Eagle Project No. 19-046.12T1 Dear Mr. Pellman, This letter report summarizes a Phase II Environmental Site Investigation (ESI) conducted by Eagle Environmental, Inc. (Eagle) at Southeast Elementary School located at 134 Warrenville Road in Mansfield Center, Connecticut (the “Site”). The Phase II ESI was completed to assess if a release of regulated materials has occurred at the Site in the vicinity of the former and current 10,000-gallon underground #2 fuel oil storage tank and in the septic system leaching fields that have served the on-Site school building. One (1) Volatile Organic Compound (VOC) was detected in one (1) soil sample collected from the former and current underground storage tank (UST) area. The VOC, Carbon Disulfide, is well below the Connecticut Department of Energy and Environmental Protection (CT DEEP) Remediation Standard Regulations (RSR) numeric criteria used herein as guidance on this project. Detected Carbon Disulfide is likely attributed to the fill surrounding the UST and not from a release of the current or former UST systems. The UST has exceeded the thirty (30) year life expectancy of sti-P3 USTs. The UST and associated piping should be removed and replaced in a timely manner. Prior to any tank removal activities, thirty (30) day notification is required by the CT DEEP as well as any applicable permits through the Town of Mansfield. Given the proposed future demolition of the school, the Town may also seek an extension from the CT DEEP to utilize the current UST system.

Two (2) VOCs were detected in an initial groundwater/drinking water sample collected from inside the well pump house at the “Well #3” spigot. Bromomethane and Chloromethane were detected at concentrations below CT DEEP criteria. The presence of Bromomethane may be due historic agricultural pest control activities. The presence of Chloromethane may be due to naturally occurring chemical reactions in soil/groundwater. Barium and Lead were also detected well below applicable CT DEEP RSR numeric criteria. Barium is often detected at low concentrations due to naturally occurring background conditions and the lead detection could be due to plumbing fixture cross-contamination.

Groundwater from the on-Site drinking wells was resampled on March 29, 2019. Samples were collected from three (3) locations within the pump house and one (1) from the kitchen faucet to confirm/assess the previous VOC detections. Chloromethane was detected in each of the four (4) samples at low, below applicable CT DEEP RSR numeric criteria. On April 8, 2019, to further assess and confirm the previous Barium and Lead detections, two (2) additional water samples were collected from the water holding tank at the pump house and from the kitchen faucet. Barium was detected in both samples at concentrations well below CT DEEP numeric criteria. No lead was detected.

Per pursuant Section 22a-6u(c) of the Connecticut General Statues, a Significant Environmental Hazard (SEH) is triggered and requires notification to CT DEEP if any drinking water supply well sample has contamination above the analytical detection limit and is associated with the pollution/site being investigated. The owner of the property must notify CT DEEP in writing of the hazard within 30 days of the hazard determination, March 28, 2019.

Due to the detected presence of Bromomethane, further soil testing for pesticides in former agricultural areas and around the school building is recommended. Prior to proposed demolition activities of the school building, waste characterization and a hazardous building material inspection (HBMI) survey is required specifically for but not limited to asbestos containing material (ACM), polychlorinated biphenyls (PCBs) and lead-based paint. Depending on the results of the survey, soil sampling adjacent to the building may require additional analysis for lead and PCBs.

Please do not hesitate to contact us at (860) 589-8257 if you have any questions or require more information.

Sincerely, EAGLE ENVIRONMENTAL, INC.

EXECUTIVE SUMMARY

Eagle Environmental, Inc. (Eagle) has performed a Phase II Environmental Site Investigation (Phase II ESI) at Southeast Elementary School located at 134 Warrenville Road in Mansfield Center, Connecticut. The Site is currently occupied by Southeast Elementary School. Historically, the Site was utilized for agricultural fields with mixed forested land until the school building was constructed in 1957.

The purpose of the Phase II ESI is to determine the absence or presence of regulated compounds that may be present as a result of releases of oil and/or hazardous substances at each of the Areas of Concern (AOCs) identified in the Conceptual Site Model (CSM). These include AOC-1 septic system leaching fields and AOC-2 former and current 10,000-Gallon underground #2 fuel oil storage tanks.

A ground penetrating radar (GPR) survey was conducted at the Site prior to drilling activities. The purpose of the GPR survey was to identify sub surface utilities associated with the septic system and the location of the underground storage tank (UST). The GPR survey identified the boundary of the UST northwest of the school building and the suspect septic system leaching fields southeast of the school building in a mixed asphalt/turf area.

The activities conducted as part of the Phase II ESI study included the advancement of eight (8) soil borings (B1 through B8), the installation of one (1) groundwater monitoring well (MW-1) and the collection and analysis of soil and groundwater samples. Due to a lack of groundwater recharge at MW-1, groundwater samples were collected from the drinking water supply wells from within the pump house and the school located north of the septic system leaching fields.

One (1) Volatile Organic Compound (VOC) was detected in one (1) soil sample collected from the former and current underground storage tank (UST) area. The VOC, Carbon Disulfide, is well below the Connecticut Department of Energy and Environmental Protection (CT DEEP) Remediation Standard Regulations (RSR) numeric criteria used herein as guidance on this project. Detected Carbon Disulfide is likely attributed to the fill surrounding the UST and not from a release of the current or former UST systems. The UST has exceeded the thirty (30) year life expectancy of sti-P3 USTs. The UST and associated piping should be removed and replaced in a timely manner. Prior to any tank removal activities, thirty (30) day notification is required by the CT DEEP as well as any applicable permits through the Town of Mansfield. Given the proposed future demolition of the school, the Town may also seek an extension from the CT DEEP to utilize the current UST system.

Two (2) VOCs were detected in an initial groundwater/drinking water sample collected from inside the well pump house at the “Well #3” spigot. Bromomethane and Chloromethane were detected at concentrations below CT DEEP criteria. The presence of Bromomethane may be due historic agricultural/pest control activities. The presence of Chloromethane may be due to naturally occurring chemical reactions in soil/groundwater. Barium and Lead were also detected well below applicable CT DEEP RSR numeric criteria. Barium is often detected at low concentrations due to naturally occurring background conditions and the lead detection could be due to plumbing fixture cross-contamination.

PHASE II ESI ES-1 APRIL 2019

Groundwater from the on-Site drinking wells was resampled on March 29, 2019. Samples were collected from three (3) locations within the pump house and one (1) from the kitchen faucet to confirm/assess the previous VOC detections. Chloromethane was detected in each of the four (4) samples at low, below applicable CT DEEP RSR numeric criteria. On April 8, 2019, to further assess and confirm the previous Barium and Lead detections, two (2) additional water samples were collected from the water holding tank at the pump house and from the kitchen faucet. Barium was detected in both samples at concentrations well below CT DEEP numeric criteria. No lead was detected. Per pursuant Section 22a-6u(c) of the Connecticut General Statues, a Significant Environmental Hazard (SEH) is triggered and requires notification to CT DEEP if any drinking water supply well sample has contamination above the analytical detection limit and is associated with the pollution/site being investigated. The owner of the property must notify CT DEEP in writing of the hazard within 30 days of the hazard determination, March 28, 2019. Due to the detected presence of Bromomethane, further soil testing for pesticides is recommended.

PHASE II ESI ii APRIL 2019

1.0 INTRODUCTION AND BACKGROUND

1.1 Introduction

Eagle Environmental, Inc., (Eagle) performed a Phase II Environmental Site Investigation (Phase II ESI) at Southeast Elementary School located at 134 Warrenville Road in Mansfield Center, Connecticut (the “Site”) on March 15, 25, 29 and April 8, 2019. The purpose of the Phase II ESI was to assess if a release of hazardous materials has occurred at the Site due to historic and/or current Site operations or conditions.

The Phase II ESI was conducted to be in general conformance with the following: the CT DEEP Remediation Standard Regulations (RSRs), the CT DEEP's September 2007 Site Characterization Guidance Document (SCGD) revised December 2010, and the Significant Environmental Hazard Condition Notification Statute established by the CT DEEP. Since the Site is not currently in a CT DEEP regulatory program the RSRs were used as guidance on the project. The Phase II ESI work scope was based on a Preliminary Conceptual Site Model (CSM) that was developed for the Site. The results of the Phase II ESI and the regulatory compliance are discussed in this report.

1.2 Conceptual Site Model (CSM)

1.2.1 Site Description

The 16.1-acre Site is located at 134 Warrenville Road in Mansfield Center, Connecticut. The Site is accessed via two (2) asphalt paved driveways off the east side of Warrenville Road.

The Site is improved by one (1) single-story masonry building of approximately 34,594 square feet originally constructed in 1957. Construction consists of slab-on-grade with a basement boiler room and pipe tunnels, masonry walls, pitched and flat roofing. The building is served by a septic system. Two (2) additions were added to the east end of the school in the late 1960s and early 2000s. Construction consists of slab-on-grade, masonry/wood framing and flat roofing. The Site includes 41,500 square feet of asphalt paving to the north and south of the building. An approximate 600 square foot concession stand with a bathroom was constructed in 2009 northeast of the Site building. Construction consists of slab-on-grade, wood framing, pitched roofing. The stand is served by a dedicated septic system. A storage shed, greenhouse/storage shed and a masonry block well pump house also exist on-Site. A Site plan is enclosed as Figure SP-1.

The school building includes twenty-three (23) classrooms, one (1) multi-purpose room (cafeteria, gymnasium & auditorium), one (1) kitchen, four (4) custodial closets throughout the building, one (1) boiler room in the basement and one (1) maintenance bay adjacent to the boiler room. Approximately 150 students, Pre-K through 4th grade, utilize the building with associated faculty. A site location is depicted on a Locus Map and Topographic Map enclosed as Figure SL-1 and Figure SL-2. The Site is located in a predominately residential/forested area nearby to the south of Mansfield Hollow Reservoir.

PHASE II ESI 1-1 APRIL 2019

The geographic coordinates for the Site are as follows:

Latitude/Longitude: 41° 46ˈ 24" N

-72° 11ˈ 27" W

UTM Coordinates: X: 733480.86, Y: 4628416.88

1.2.2 Area Receptors

The nearest natural surface water body is Schoolhouse Brook located approximately 400 feet west of the Site which discharges to the Fenton River and then Mansfield Hollow Lake. Groundwater at the Site flows northerly towards Mansfield Hollow Lake according to a 2010 Septic Suitability Report prepared by Anchor Engineering Services, Inc.

1.2.3 Geology

According to the CT DEEP Surficial Materials Map of Connecticut (Stone 1992), the materials beneath the Site are mapped as sand and gravel overlying sand overlying fines. Sand and gravel is generally less than 20ft thick, horizontally bedded and overlies thicker inclined beds of sand which in turn overlie thinly bedded fines of variable thickness (deltaic deposits overlying lake-bottom sediment).

According to the “Bedrock Geological Map of Connecticut” (Rodgers, 1985), the bedrock underlying the Site is described as the Waterford Group. Bedrock is characteristically light to dark, medium-grained gneiss.

1.2.4 Groundwater Classification

According to the CT DEEP Water Quality Classifications Map of Connecticut (2015), the Site is a GA, GAA groundwater classification area that may not meet current standards of the presumption that groundwater is suitable for drinking without prior treatment. The Site is also located in an area that contributes to a public supply well.

1.2.5 Hydrogeology

Groundwater flow direction is northerly towards Mansfield Hollow Lake located just north of the Site. Mansfield Hollow Lake discharges into the Willimantic reservoir and Natchaug River.

1.2.6 Previous Studies

Eagle prepared a “Phase I Environmental Site Assessment Southeast Elementary School – 134 Warrenville Road, Mansfield Center, Connecticut, Eagle Project No. 19-046.12T1” on March 22, 2019. A copy of the report (text only) is included in Appendix A. The following are conclusions and recommendations based on the completed Phase I ESA: The Phase I ESA revealed evidence of two (2) historic and one (1) recognized environmental conditions (HRECs and REC) in connection with the Site at the time of this report.


HREC No. 1: Septic System Leaching Fields Southeast Elementary School was constructed in 1957 with an on-Site septic system and leaching fields located southeast of the building. If halogenated solvents (commonly found in floor strippers and cleaners prior to 1980) or other products potentially containing contaminant compounds were previously used in the building, the constituents and residual rinse water may have been disposed of into the septic system with potential to impact soil and/or groundwater within the vicinity of the leaching fields. HREC No. 2: Underground Storage Tank A1 One (1) former 10,000-gallon heating oil UST (Tank ID A1) was said to be located within the same area as the current UST and removed from the ground 07/01/1988. No additional information was available to review. Specifically, a closure report or analytical summary of soil and/or groundwater results from the tank removal activity was not observed at the time of this report. Should a release of fuel oil have occurred, there is potential for an impact to soil and/or groundwater unless official documentation can prove a release had not occurred. REC No. 1: Underground Storage Tank A1R1 One (1) 10,000-gallon sti-P3 #2 fuel oil UST (Tank ID A1R1) exists on-Site north of the building. The UST was installed 07/01/1988 and has exceeded the thirty (30) year life expectancy of sti-P3 USTs. Mansfield Facilities Department provided a copy of the cathodic protection monitoring log dated June 15, 2018 indicating the UST passed testing. It is unclear however, if just the UST was cathodically tested or if the return/supply piping was included. Until the UST is removed from the ground, or abandoned in place, there is potential for a release to soil and/or groundwater within the vicinity of the UST and associated piping.

Eagle recommended conducting a Phase II Environmental Site Investigation (ESI) to assess the presence of a release of regulated substances to soil and/or groundwater at the Site to address the two (2) HRECs and one (1) REC observed in connection with the property. The remainder of this report will reference the HRECs and REC previously identified as Area of Concerns (AOCs) to comply with the CT DEEP Site Characterization Guidance Document (SCGD). The AOCs for the Site are summarized in Section 3.0.

1.2.7 Constituents of Concern

Based on the historic use of the Site, the presence of a release of the following constituents of concern (COCs) were assessed during this investigation:

• Extractable Total Petroleum Hydrocarbons (ETPH) • Polyaromatic Hydrocarbons (PAHs) • RCRA 8 Total Metals (RCRA 8 TM) • Volatile Organic Compounds (VOCs)

2.0 REGULATORY FRAMEWORK

2.1 Connecticut Transfer Act

The Connecticut Transfer Act (CTA) (Connecticut General Statute (CGS) Section 22a-134)


regulates the transfer, investigation and remediation of Hazardous Waste Establishments. An Establishment is defined as any real property at which or any business from which:

• on or after November 19, 1980, there was generated, except as a result of remediation of polluted soil, groundwater or sediment more than one hundred kilograms of hazardous waste in any one month;

• hazardous waste generated at a different location was recycled, reclaimed, reused, stored, handled, treated, transported or disposed of;

• the process of dry cleaning was conducted on or after May 1, 1967; • furniture stripping was conducted on or after May 1, 1967; or, • A vehicle body repair facility was located on or after May 1, 1967.

Facilities that are considered Establishments under the CTA are subject to certain reporting requirements to the CT DEEP when a transfer of ownership occurs. These reporting requirements include: 1) one of four filing forms (Form I, II, III, IV) and 2) an Environmental Condition Assessment Form (ECAF) of which need to be submitted to the CT DEEP. In order to achieve compliance with the CTA and achieve CT DEEP approval or verification by a LEP, it is necessary to demonstrate that all potential release areas at the Site have been investigated in accordance with standard and prevailing guidelines, and that remediation has been completed, including any post remedial groundwater monitoring, if necessary. The Site does not appear to qualify as an ”Establishment” and therefore, would not be subject to the legal and technical requirements of the CTA in the event of a transfer of ownership. 2.2 Remediation Standard Regulations

The CT DEEP has developed the RSRs, Sections 22a-133k-1 through 3 of the Regulations of the Connecticut State Agencies (RCSA), that specify the allowable levels of regulated compounds in soil and groundwater for both GA (groundwater presumed drinkable without treatment) and GB (presumed unsuitable for drinking without treatment) groundwater classification areas. The RSRs are typically used for all sites undergoing environmental investigations as a baseline to evaluate a site’s potential environmental liability. However, RSRs only legally apply to sites that are under order from the CT DEEP to perform remediation, are considered a Hazardous Waste Establishment as defined by the CTA or are undergoing voluntary remediation where verification by the CTDEEP or an LEP is needed. The RSRs are being used herein as guidance on this project.

2.2.1 Soil Criteria

The RSRs define two criteria that apply to soil: the Direct Exposure Criteria (DEC) and the Pollutant Mobility Criteria (PMC). The DEC defines the maximum level of regulated compounds allowed in soil to a depth of 15 feet below ground surface (bgs) without posing a threat due to direct human exposure, while the PMC sets the maximum level of regulated compounds allowed in soil above the water table without posing a threat to groundwater quality. Each criterion is further


divided into two categories; the DEC is based upon Site usage (i.e. Residential or Industrial/Commercial use), while the PMC is based on the groundwater classification (i.e.GA/GAA or GB). The Site is located in a GA/GAA groundwater classification area and therefore would be required to meet the GA/GAA PMC. The Residential DEC (RDEC) must be met if a Site is to be used for residential purposes. The CTDEEP and the RSRs define “residential activity” to include any activity related to a residence or dwelling, or to a school, hospital, day care center, playground, or outdoor recreation area. If a Site or property is not to be used for residential purposes, then the Industrial/Commercial DEC may be met if an Environmental Land Use Restriction (ELUR) is filed for the Site. The ELUR would limit the Site to industrial or commercial usage. The DEC does not apply if soil meets the definition of “inaccessible” and the PMC does not apply if soil meets the definition of “environmentally isolated”. In either case, an ELUR is required. Soil can be rendered ”inaccessible” if the impacted soil is covered by four feet of clean fill (non- polluted material), or covered by two feet of clean fill and a minimum of three inches of asphalt, or covered by a building or other permanent structure. Soils that are isolated beneath a building or other impermeable structure may be considered “environmentally isolated”, such that with the use of an ELUR, the PMC does not apply. Pavement is not considered impermeable and cannot be used to render soil environmentally isolated. Additionally, the RSRs provide certain exceptions and variances with regard to polluted fill when specific criteria are met for the Site. Moreover, the RSRs also provide several self- implementing options for assessment and remediation of regulated compounds in soil.

2.2.2 Groundwater Criteria

The RSRs define three criteria that apply to groundwater: the Groundwater Protection Criteria (GWPC), the Surface Water Protection Criteria (SWPC), and the Volatilization Criteria (VC). The GWPC defines the maximum levels of regulated compounds allowed in groundwater for protection of the groundwater as a potable water source. The GWPC applies to Sites located in a GA/GAA groundwater quality area. The Site is located in a GA/GAA area; therefore, the GWPC does apply at the Site.

The SWPC applies to impacted groundwater that is discharging to a surface water body, including wetlands, streams, rivers, ponds, lakes and Long Island Sound. One standard has been set for all surface water bodies, regardless of quality classification. The SWPC specifies the levels of compounds allowable in groundwater just prior to discharging into surface water. For sites without surface water nearby, compliance with the SWPC is based on the average plume concentration across the site. The RSRs also allow the evaluation of an alternative SWPC, based on available dilution in the receiving water body. Groundwater from the Site discharges to Mansfield Hollow Lake; the Site must comply with the SWPC.

The VC sets the allowable levels of VOCs in groundwater that is less than 15 feet bgs. The VC is designed to protect humans from exposure to VOCs present in shallow groundwater. Residential and industrial/commercial VC have been established, with the residential VC being more stringent, and the industrial/commercial VC requiring the use of an ELUR. The VC may not have


to be met if monitoring of soil vapor above the water table or indoor air quality demonstrates that there is no exposure hazard. The Site must comply with the Residential VC because there is no ELUR for the Site.

3.0 PHASE II ENVIRONMENTAL SITE INVESTIGATION

3.1 Phase II Environmental Site Investigation Project Approach

Eagle conducted a Phase II ESI to evaluate the Areas of Concern (AOCs) identified below. Based on the findings of the 2019 Phase I ESA performed previously, and cognizance of the CT DEEP Site Characterization Guidance Document (SCGD), Eagle developed a Conceptual Site Model for the Site. Based on site history discussed in greater detail in Section 1.2.7, COCs may exist in the vicinity of the following AOCs:

Conceptual Site Model AOC

Number Name AOC Location

1 Septic System Leaching Fields Southeast of the school building

2 Former and current 10,000-Gallon Underground

#2 Fuel Oil Storage Tanks Northwest of the school

building

3.2 Ground Penetrating Radar Survey

On March 14, 2019, Sub-Surface, LLC of East Longmeadow, Massachusetts mobilized to the Site to conduct a ground penetrating radar (GPR) survey of each AOC. The GPR survey was conducted to investigate the location of an underground storage tank (UST) and sub surface features associated with leaching fields utilized on-Site. The GPR survey identified the boundary of the UST northwest of the school building and the suspect septic system leaching fields southeast of the building in a mixed asphalt/turf area. Geophysical Survey results are presented in Appendix B.

3.3 Soil Boring and Groundwater Monitoring Well Installation

On March 15, 2019 Kropp Environmental Contractors, Inc. of Lebanon, Connecticut mobilized a track-mounted Geoprobe 7822DT rig to the Site. Four (4) test borings were advanced in the vicinity of AOC-1 and four (4) in vicinity of AOC-2. Geoprobe test borings were advanced to a depth of 16-30 ft. Soil samples were collected at test borings B1 through B8 to assess the presence/absence of ETPH, PAHs, RCRA 8 Total Metals and VOCs. Test borings were monitored by Eagle and soil conditions were logged in the field. Soil boring logs are presented in Appendix C.

A groundwater monitoring well was installed in the completed test boring B3/MW-1. Due to a lack of observed groundwater beyond 30 feet below ground surface, one (1) groundwater well was completed during the drilling activities. Refer to Figure SP-1 for the soil test boring and


groundwater monitoring well installation locations. A summary table detailing the test boring locations and corresponding AOCs are presented below:

Soil samples were collected continuously using four-foot direct-push soil samplers, affixed with acetate sleeves, and advanced with the Geoprobe from the ground surface to a maximum depth of sixteen (16) feet (30 feet for the attempted groundwater well locations). Retrieved samplers were placed on an examination table and the acetate sleeves were carefully cut open to minimize soil sample disturbance. Retrieved soil was field-screened for the presence of total volatile organic compounds (VOCs) using a MiniRAE 3000 (serial Number 592-916914) photo-ionizing detector (PID) equipped with a 10.6 eV lamp pre-calibrated with Isobutylene gas. Soil samples were collected from each test boring and placed into glass containers and preserved in accordance with analytical methods. Samples collected for VOC analysis were obtained using a dedicated polyethylene syringe as a soil micro-core sampler to ensure an undisturbed sample. Soil core samples were placed directly into three (3), laboratory-prepared, 40-ml Volatile Organic Ampoules (VOAs) including one containing 5 milliliters (mls) of methanol and two (2) containing 5 mls of de-ionized water. Sample collection methods were completed in accordance with CTDEEP VOC sampling protocols. Immediately after collection, samples were placed directly into an ice cooler and/or freezer where they were held under proper chain of custody until they were delivered to the laboratory. No petroleum or solvent odors, stained soil, or PID readings were detected in AOC-1 or AOC-2 during the investigation Based on the field screening results and understanding of the vertical extent of the AOCs, soil samples were selected and, along with two (2) quality control samples, were submitted to Phoenix Environmental Laboratories, Inc., a Connecticut-certified laboratory, located in Manchester, Connecticut. Laboratory analysis included Extractable Total Petroleum Hydrocarbons (ETPH), Polyaromatic Hydrocarbons (PAHs) by EPA Method 8270, RCRA 8 Total Metals (RCRA 8 TM) by EPA Method 6000/7000 and Volatile Organic Compounds (VOCs) by EPA Method 8260. The following soil samples were submitted for quality control/quality assurance (QA/QC) purposes: soil sample No. 0315192468 (duplicate of soil sample No. B2 S4) was submitted as a blind duplicate and soil sample No. 031519771214 (duplicate of soil sample No. B7 S7) was submitted as a matrix spike/matrix spike duplicate. Both samples were analyzed for VOCs only.

3.4 Groundwater Sampling

On March 20, 2019, Eagle attempted to collect groundwater from the newly installed monitoring well (B3/MW-1) using EPA low-flow sampling methodology. However, due to lack of water in the well column, no sampling could be completed.

On March 25, 2019, Eagle collected a groundwater sample from onsite drinking water supply “Well #3” located approximately 120 feet east of the pump house. The well was sampled from a spigot located after the in-line water meter and before the holding tank. The line was purged for only approximately 30 seconds before collection. A 2007 well installation record indicated that the well was installed to a depth of 500 feet including the first 83 feet in sand and gravel and the remaining depth in to bedrock.

Groundwater from the on-Site drinking water supply was resampled on March 29, 2019 to confirm/assess previous well VOC detections. Samples were collected from three (3) locations within the pump house including both of the two (2) well inlet spigots and one (1) from after the holding tank (before the circulation pumps and expansion tanks). One (1) sample was also collected from the kitchen faucet to confirm/assess the previous VOC detections. The samples from the pump house were collected after each sample outlet was purged for approximately 20 minutes and the kitchen sample was collected after approximately one (1) hour of purging. On April 8, 2019, to further assess and confirm previous Barium and Lead detections, two (2) additional water samples were collected from after the water holding tank at the pump house and from the kitchen faucet. Both samples were collected after approximately 20 minutes of purging.

The samples were directly placed into the appropriate containers and preserved in accordance with analytical methodology. Immediately after collection, samples were placed into an ice cooler where they were held under proper chain of custody until they were delivered to the laboratory for analysis. The samples were submitted to Phoenix Environmental Laboratories, Inc., a Connecticut-certified laboratory, located in Manchester, Connecticut. Laboratory analysis for drinking water included VOCs by EPA Method 8260, ETPH and RCRA 8 TM by EPA Method 6000/7000.

Groundwater was observed at 47.2 feet from the top of the PVC casing a previously installed monitoring well in the northern portion of the site.

4.0 SITE INVESTIGATION ANALYTICAL RESULTS

4.1 Laboratory Reasonable Confidence Protocols

Soil analytical results are presented in Appendix D. Groundwater analytical results are presented in Appendix E. A review of the laboratory narratives for the soil and groundwater indicates that no significant bias has been observed with the data.

The duplicate soil sample was non-detect for all VOCs. The matrix spike/matrix spike duplicate (MS/MSD) sample was also was non-detect for all VOCs.


The LCS/LCSD recovery of the MS/MSD is acceptable. One or more analytes in the site-specific matrix spike recovery is below the lower range but within the method criteria. A slight low bias is possible for some compounds. The MSD recovery is above the upper range for one analyte that was not reported in the sample(s), therefore no significant bias is suspected. (Hexachlorobutadiene). Overall, based on the QA/QC the data is usable for the intended purpose.

Carbon Disulfide at B6 S6 (10.0-12.0ˈ) was detected above the laboratory reporting limit but well below applicable RSR numeric criteria.

VOCs were non-detect in the soil sample matrix spike/matrix spike duplicate.

4.1.2 Groundwater Analytical Results

Groundwater analytical results are summarized in Table II. Applicable CTDEEP RSRs are presented on the table for informational purposes and to assess if a release has occurred to groundwater at the Site. A summary of groundwater results is presented below.


ETPH was not detected in groundwater above the laboratory RL.


Two (2) VOCs were detected above the laboratory reporting limit but below applicable RSR numeric criteria in the first sample collected from the “MW-3” spigot in the pump house. Bromomethane was detected at 0.00094 mg/l in the sample and could be the result of historic agricultural/pesticide fumigant practices in the area. Chloromethane was detected at 0.0012 mg/l and is likely the result of natural chemical reactions occurring in soil/groundwater. Each VOC detected is well below applicable RSR numeric criteria. One (1) tentatively identified compound, Isopropyl Alcohol, was detected in the groundwater sample likely from a disinfectant or hand sanitizer used within the pump house and not associated with the groundwater sample.

During the second round of groundwater samples collected from the pump house and school kitchen faucet, Chloromethane was detected in all four (4) samples at concentrations ranging from 0.0012 mg/l to 0.0019 mg/l. No other VOCs were detected.

RCRA 8 Total Metals (RCRA 8 TM)

Two (2) metals were detected above the laboratory reporting limit, but well below applicable RSR numeric criteria in the first sample collected from the pump house. Barium was detected at 0.004 mg/l and is likely associated with natural background conditions. Lead was detected at 0.0014 mg/l and is likely the result of plumbing fixture residue as a result of insufficient flushing prior to collection from the well sampling outlet.

Barium was detected in both second-round samples collected from the pump house and the kitchen faucet at concentrations of 0.004 mg/l each.

PHASE II ESI 4-3 FEBRURAY 2019

5.0 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS

5.1 Summary

Eagle Environmental, Inc. (Eagle) has performed a Phase II Environmental Site Investigation (Phase II ESI) at Southeast Elementary School located at 134 Warrenville Road in Mansfield Center, Connecticut. The Site is currently occupied by Southeast Elementary School. Historically, the Site was utilized for agricultural fields with mixed forested land until the school building was constructed in 1957.

The purpose of the Phase II ESI is to determine the absence or presence of regulated compounds that may be present as a result of releases of oil and/or hazardous substances at each of the Areas of Concern (AOCs) identified in the Conceptual Site Model (CSM). These include AOC-1 septic system leaching fields and AOC-2 former and current 10,000-Gallon underground #2 fuel oil storage tanks.

A ground penetrating radar (GPR) survey was conducted at the Site prior to drilling activities. The purpose of the GPR survey was to identify sub surface utilities associated with the septic system and the location of the underground storage tank (UST). The GPR survey identified the boundary of the UST northwest of the school building and the suspect septic system leaching fields southeast of the school building in a mixed asphalt/turf area.

The activities conducted as part of the Phase II ESI study included the advancement of eight (8) soil borings (B1 through B8), the installation of one (1) groundwater monitoring well (MW-1) and the collection and analysis of soil and groundwater samples. Due to a lack of groundwater recharge at MW-1, groundwater samples were collected from the drinking water supply wells from within the pump house located north of the septic system leaching fields.

One (1) Volatile Organic Compound (VOC) was detected in one (1) soil sample collected from the former and current underground storage tank (UST) area. The VOC, Carbon Disulfide, is well below the Connecticut Department of Energy and Environmental Protection (CT DEEP) Remediation Standard Regulations (RSR) numeric criteria used herein as guidance on this project. Detected Carbon Disulfide is likely attributed to the fill surrounding the UST and not from a release of the current or former UST systems. The UST has exceeded the thirty (30) year life expectancy of sti-P3 USTs. The UST and associated piping should be removed and replaced in a timely manner. Prior to any tank removal activities, thirty (30) day notification is required by the CT DEEP as well as any applicable permits through the Town of Mansfield. Given the proposed future demolition of the school, the Town may also seek an extension from the CT DEEP to utilize the current UST system.

Two (2) VOCs were detected in an initial groundwater/drinking water sample collected from inside the well pump house at the “Well #3” spigot. Bromomethane and Chloromethane were detected at concentrations below CT DEEP criteria. The presence of Bromomethane may be due historic agricultural pest control activities. The presence of Chloromethane may be due to naturally occurring chemical reactions in soil/groundwater. Barium and Lead were also detected well below applicable CT DEEP RSR numeric criteria. Barium is often detected at low


concentrations due to naturally occurring background conditions and the lead detection could be due to plumbing fixture cross-contamination. Groundwater from the on-Site drinking wells was resampled on March 29, 2019. Samples were collected from three (3) locations within the pump house and one from the (1) kitchen faucet to confirm/assess the previous VOC detections. Chloromethane was detected in each of the four (4) samples at low, below applicable CT DEEP RSR numeric criteria. On April 8, 2019, to further assess and confirm the previous Barium and Lead detections, two (2) additional water samples were collected from the water holding tank at the pump house and from the kitchen faucet. Barium was detected in both samples at concentrations well below CT DEEP numeric criteria. No lead was detected. Per pursuant Section 22a-6u(c) of the Connecticut General Statues, a Significant Environmental Hazard (SEH) is triggered and requires notification to CT DEEP if any drinking water supply well sample has contamination above the analytical detection limit and is associated with the pollution/site being investigated. The owner of the property must notify CT DEEP in writing of the hazard within 30 days of the hazard determination, March 28, 2019. 5.2 Revised CSM

Based on a conceptual site model developed for this Phase II ESI, soil samples were collected within AOC-1 (Septic System Leaching Fields) and AOC-2 (Former and Current 10,000-Gallon Underground #2 Fuel Oil Storage Tanks) and analyzed for the presence of ETPH, PAHs, RCRA 8 TM and VOCs. The analysis was performed to assess if a release of regulated materials has occurred due to historic use of a septic system and utilization of a former and current 10,000-gallon #2 fuel oil USTs on-Site.

Soil collected during this investigation consisted predominately of fine gravelly coarse to fine sand. Groundwater flow direction at the time of groundwater sampling on March 25, 2019 was presumed northerly towards Mansfield Hollow Lake.

Analytical testing for the presence of ETPH, PAHS, RCRA 8 TM and VOCs revealed no release has occurred to soil at AOC-1 and AOC-2.

Bromomethane was detected in the first well water sample collected and is likely attributable to historical agricultural use or pest control in the area/on-Site. Chloromethane was detected in the initial and subsequent confirmatory groundwater samples and is likely attributable to naturally occurring chemical reactions in soil/groundwater. Lead was detected in the first well water sample and was attributed to plumbing fixture residue and lack of flushing prior to sample collection. Barium was detected in all the samples analyzed for metals and is typical of low-level background concentrations observed in Connecticut.

5.3 Conclusions and Recommendations

No release was detected in the areas of the septic leaching system or the UST area. The UST has exceeded the thirty (30) year life expectancy of sti-P3 USTs. The UST and associated piping


should be removed and replaced in a timely manner. Prior to any tank removal activities, thirty (30) day notification is required by the CT DEEP as well as any applicable permits through the Town of Mansfield. Alternatively, the Town may seek to extend the use of the tank year by year given the planned site demolition and reconstruction activities. Bromomethane initially detected in the drinking water well supply could indicate the presence of pesticides in the vicinity or onsite from agricultural activities or pest control around the school grounds. Confirmatory soil testing for pesticides is recommended in former agricultural areas and around the older portions of the school building. Per pursuant Section 22a-6u(c) of the Connecticut General Statues, a Significant Environmental Hazard (SEH) reporting has been triggered and requires notification to CT DEEP due to the detection of contaminants above the analytical detection limit in a drinking water supply well. Due to the detected presence of Bromomethane, further soil testing for pesticides in former agricultural areas and around the school building is recommended. Prior to proposed demolition activities of the school building, waste characterization and a hazardous building material inspection (HBMI) survey is required specifically for but not limited to asbestos containing material (ACM), polychlorinated biphenyls (PCBs) and lead-based paint. Depending on the results of the survey, soil sampling adjacent to the building may require additional analysis for lead and PCBs. 6.0 LIMITATIONS

Dear Mr. Pellman:

Eagle Environmental, Inc. (Eagle) completed a Phase I Environmental Site Assessment for the Southeast Elementary School located at 134 Warrenville Road in Mansfield Center, Connecticut(the “Site”). The Phase I Environmental Site Assessment was performed in general accordance with American Testing and Materials (ASTM) standards E1527-13 and meets EPA’s All Appropriate Inquiry (AAI) standard. This assessment has revealed evidence of two (2) historic and one (1) recognized environmental condition (HRECs and REC) in connection with the property at the time of this report.

Eagle recommends a Phase II environmental site investigation to assess if a release of oil and/or hazardous substances have occurred at the two (2) HRECs and one (1) REC.

In our opinion, the Site does appear to qualify as an “Establishment” as defined by the Connecticut Property Transfer Law.

Please contact us directly if you have any questions related to the report.

Sincerely,Eagle Environmental, Inc.

EXECUTIVE SUMMARY

Eagle Environmental, Inc. (Eagle) conducted a Phase I Environmental Site Assessment (ESA) atSoutheast Elementary School located at 134 Warrenville Road in Mansfield Center, Connecticut (hereinafter referred to as “the Site”). This Phase I ESA was performed in accordance with the scope and limitations of American Society for Testing and Materials (ASTM) standards E1527-13 and meets EPA’s All Appropriate Inquiry (AAI) standard. The Phase I ESA included an environmental databases search, review of local, state, and federal regulatory agency files, and a limited reconnaissance of the Site and vicinity for potential off-site contamination sources. No sampling or other intrusive activities were conducted as part of the Phase I ESA. Additionally, an evaluation for the presence of suspected asbestos-containing material (ACM), lead-based paint (LBP), poly-chlorinated biphenyls (PCB) containing building materials or radon gas was not included in the scope of work for the ESA.

The major findings of the Phase I ESA are as follows:

The Site consists of one (1) parcel of land totaling 16.1-acres;

The Site is improved by one (1) single-story masonry building of approximately 34,594square feet originally constructed in 1957. Construction consists of slab-on-grade with a basement boiler room and pipe tunnels, masonry framing, pitched and flat roofing and a septic system. Two (2) additions were added to the east end of the school in the late 1960s in early 2000s. Construction consists of slab-on-grade, masonry/wood framing and flat roofing. The Site includes 41,500 square feet of asphalt paving to the north and south of the building. An approximate 600 square foot concession stand with a bathroomwas constructed in 2009 northeast of the Site building. Construction consists of slab-on-grade, wood framing, pitched roofing and an independent septic system. A storage shed, greenhouse/storage shed and a masonry block well pump house also exists on-Site;

The school building includes twenty-three (23) classrooms, one (1) multi-purpose room (cafeteria, gymnasium & auditorium), one (1) kitchen, four (4) custodial closets throughout the building, one (1) boiler room in the basement and one (1) maintenance bay adjacent to the boiler room. Approximately 150 students, grades Pre-K through 4th

grade, utilize the building with associated faculty;

The Site is currently occupied by Southeast Elementary School. Historically, the Site was utilized for agricultural fields with mixed raw land until the Site building was constructed in 1957;

The Site building utilizes an on-Site septic system, onsite water supply wells, and #2 fuel oil for heating;

One (1) approximate 10,000-gallon sti-P3 #2 heating oil underground storage tank (UST) exists on the north side of the school building. The UST was installed 07/01/1988 and has exceeded the thirty (30) year life expectancy of sti-P3 USTs. A former 10,000-gallon

PHASE I ESA ES-1 MARCH 2019

heating oil UST was reportedly located within the same area installed in 1957 and removed from the ground 07/01/1988;

One (1) backup generator with a self-contained diesel tank exists north of the school within a wood enclosure. Staining on or adjacent to the generator was not observed;

One (1) concrete pad-mounted transformer exists north of the school within a wood enclosure. No label indicating the presence or absence of PCB containing di-electric fluid was observed;

The Site is listed on the CT UST, SPILLS and FINDS databases contained in an EDR environmental database report for two (2) registered USTs and a release of 2-gallons of #2 fuel oil in 2015;

There is low potential that a vapor encroachment condition VEC exists at the Site based upon a lack of documented releases within the area and current and historic chemical utilization/storage on and off-Site;

An ACM inspection was not included as part of this Phase I ESA, however, suspect ACM may exist within the pipe tunnels below the school and within inaccessible areas (above ceilings/behind walls). The Site building appeared to have been recently renovated with new floor tile; and,

The Site does not appear to qualify as an “Establishment” as defined by the Connecticut Transfer Act due to a lack of observed evidence that on or after November 19, 1980 the Site generated more than one hundred (100) kilograms of hazardous waste in any one month. Advice from legal counsel is suggested to confirm a final determination.

Eagle identified one (1) significant data gap, as defined by ASTM E1527-13, during the Site reconnaissance and records review that would significantly affect the ability of Eagle to identify recognized environmental conditions in connection with the Site.

One (1) former 10,000-gallon heating oil UST (Tank ID A1) was reportedly located within the same area as the current UST and removed from the ground June 1, 1988. No additional information was available to review. Specifically, a closure report or analytical summary of soil and/or groundwater results from the tank removal activity was not observed at the Town of Mansfield Municipal Departments or at CTDEEP at the time of this report.

This assessment has revealed evidence of two (2) historic and one (1) recognized environmental conditions in connection with the Site at the time of this report.

HREC No. 1: Septic System Leaching FieldsSoutheast Elementary School was constructed in 1957 with an on-Site septic system and leaching fields located southeast of the building. If halogenated solvents (commonly found in floor strippers and cleaners prior to 1980) or other products potentially containing contaminant compounds were previously used in the building, the constituents and residual rinse water may


have been disposed of into the septic system with potential to impact soil and/or groundwater within the vicinity of the leaching fields.

HREC No. 2: Underground Storage Tank A1One (1) former 10,000-gallon heating oil UST (Tank ID A1) was reportedly located within the same area as the current UST and removed from the ground 07/01/1988. No additional information was available to review. Specifically, a closure report or analytical summary of soiland/or groundwater results from the tank removal activity was not observed at the time of this report. Should a release of fuel oil have occurred, there is potential for an impact to soil and/or groundwater unless official documentation can prove a release had not occurred.

REC No. 1: Underground Storage Tank A1R1One (1) 10,000-gallon sti-P3 #2 fuel oil UST (Tank ID A1R1) exists on-Site north of the building. The UST was installed 07/01/1988 and has exceeded the thirty (30) year life expectancy of sti-P3 USTs. Mansfield Facilities Department provided a copy of the cathodic protection monitoring log dated June 15, 2018 indicating the UST passed testing. It is unclear however, if just the UST was cathodically tested or if the return/supply piping was included. Until the UST is removed from the ground, or abandoned in place, there is potential for a release to soil and/or groundwater within the vicinity of the UST and associated piping.

Based on the findings and conclusions discussed herein, Eagle offers the following recommendations:

Eagle recommends conducting a Phase II Environmental Site Investigation (ESI) to assess the presence of a release of regulated substances to soil and/or groundwater at the Site to address the two (2) HRECs and one (1) REC observed in connection with the property.

Eagle also recommends the timely removal and replacement of the underground storage tank (UST) A1 and associated piping due to the exceedance of the thirty (30) year life expectancy. Prior to any tank removal activities, thirty (30) day notification is required by the Connecticut Department of Energy and Environmental Protection (CTDEEP) as well as any applicable permits through the Town of Mansfield.

PHASE I ESA iii MARCH 2019

1.0 INTRODUCTION

Eagle Environmental, Inc. (Eagle) conducted a Phase I Environmental Site Assessment (ESA) at Southeast Elementary School located at 134 Warrenville Road in Mansfield Center, Connecticut (hereinafter referred to as “the Site”). The Phase I ESA is being conducted to support the potential future consolidation of the three (3) Mansfield Elementary Schools into a single centrally located facility.

The purpose of the Phase I ESA is to determine if Recognized Environmental Conditions(RECs)1 are present in connection with the Site from past or present property usage in accordance with the Comprehensive Environmental Response, Compensation and Liability Act(CERCLA) of 1980 as amended, 40 USC 9601, et seq. Furthermore, the Phase I ESA will assess applicable levels of environmental compliance; environmental liability; hazardous material stored, released or disposed of on Site; and the need for characterization investigation, if required. In addition, this Phase I ESA renders an opinion as to whether the Site is an “Establishment” as defined under the Connecticut Transfer Act (Sections 22a-134 through 22a -134e of the Connecticut General Statutes), as amended by Public Acts 09-235 and 09-3.

This Phase I ESA was conducted in conformance with the scope and limitations of American Society for Testing and Materials (ASTM) standard for the Phase I Environmental Site Assessment Process (ASTM E1527-13) which is compliant with EPA’s All Appropriate Inquiry (AAI) rule (40 CFR §312). In addition, this Phase I ESA meets the requirements of the Site Characterization Guidance Document published by the Connecticut Department of Energy and Environmental Protection (CT DEEP) and the Connecticut Housing Finance Authority (CHFA) Construction Guidelines: Environmental & Hazardous Materials Review January 2018.

1.1 Purpose

This assessment utilized the general quality principles and practices towards the preparation of a report that incorporates suggested methods under the ASTM. The term “recognized environmental condition” (REC) referenced in the revised ASTM E1527-13 refers to “the presence or likely presence of any hazardous substances or petroleum products in, on or at a property under conditions that indicate an existing release, a past release or a material threat of a release of hazardous substance or petroleum products into structures on the property or into the ground, groundwater, or surface water of the property.” The ASTM definition does not include “de minimis” conditions, which generally do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of the appropriate government agencies. Therefore, de minimis conditions are not considered RECs. A new term “controlled recognized environmental condition” (CREC) referenced in the revised ASTM E1527-13 refer to “sites where a REC from past releases has been addressed to standards and either hazardous substances or petroleum remain in place with implementation of required controls”.

The Phase I ESA includes the following tasks:

1 Recognized environmental conditions – the presence or likely presence of any hazardous substances or petroleum products in, on or at a property: (1) due to release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not recognized environmental conditions.

PHASE I ESA 1-1 MARCH 2019

Review of an environmental database search report for sites identified on databases including National Priorities List (NPL); Comprehensive Environmental Response Compensation and Liability Act (CERCLA); Resource Conservation and Recovery Act (RCRA); emergency response notification sites; a state spill, release, and landfill sites;

Review of files at the Tax Assessor’s Office, Health Department, Town Clerk, Fire Marshal’s Office and the Building/Engineering/Zoning Department;

Site reconnaissance to observe conditions exposed at the ground surface for evidence of previous and current property usage, and indications of environmental impact (e.g., stressed vegetation, staining, etc.);

Reconnaissance of surrounding properties to identify potential off-site sources of contamination; and

Vapor encroachment screening based on information obtained via the environmental database report, local and/or state research and interview documentation.

In accordance with the approved scope of work, Eagle did not collect samples for suspect asbestos containing material (ACM), lead-based paint (LBP), or radon gas. This Phase I ESA was performed in accordance with the limitations and exceptions identified in Section 14.0 of this report.

5.0 DATABASE SEARCH REPORT AND MUNICIPAL RECORDS

5.1 Standard Environmental Record Sources

Eagle retained Environmental Data Resource, Inc. (EDR) of Milford, Connecticut to perform an on-line radius search (based on AAI standards) of applicable State and federal environmental databases. The EDR (Appendix C), dated March 8, 2019, reviewed the following databases for the area within the specified radius of the subject parcel:

Environmental Protection Agency (EPA) National Priorities List (NPL), 1-mile radius;Environmental Protection Agency (EPA) National Priorities List (NPL) Delisted site, 1/2-mile radius;EPA Comprehensive Environmental Response Compensation Liability Information System (CERCLIS) List (which included EPA Superfunds sites), 1/2-mile radius;EPA Comprehensive Environmental Response Compensation and Liability Information System Archived sites (CERCLIS NFRAP), 1/2-mile radius;Resource Conservation and Recovery Act (RCRA) sites (Generators within 1/2-mile radius; Treatment, Storage and Disposal facilities within 1/2-mile radius; and Corrective Action sites within 1-mile radius);Federal Institutional Controls/Engineering Controls (IC/EC), 1/2-mile radius;Emergency Response Notification System (ERNS) sites, 1/8-mile radius;Tribal Lands (database of boundaries in which American Indian tribes have primary governmental authority, administered by the Bureau of Indian Affairs), 1-mile radius;State/Tribal Hazardous Waste sites, 1-mile radius;State/Tribal Spill Sites; 1/8-mile radius;Solid/Tribal Waste Landfill sites, 1/2-mile radius;State/Tribal Registered Underground storage Tanks (USTs) and Aboveground Storage Tanks (ASTs) listings,) 1/4-mile radius;State/Tribal Leaking Underground Storage Tanks (LUSTs) listing, 1/2-mile radius;State/Tribal Institutional Control (IC) database, 1/2-mile radius;State/Tribal Brownfields sites, 1/2-mile radius;State/Tribal Voluntary Cleanup Program (VCP) sites, 1/2-mile radius; and,State Other (database of sites within the (CTDEEP’s Property Transfer Program), 1/4-mile radius.

Eagle reviewed the area topography as it relates to the Site and determined an inferred direction of groundwater flow through the Site and adjacent area to be northwesterly/northerly towards Schoolhouse Brook that discharges to Mansfield Hollow Lake. Based on this inferred direction of groundwater flow, properties (within the search radii specified above) located south/southeastand upgradient of the Site will be discussed as it relates to the potential environmental impact to the Site. The location of the Site is depicted on the Topographic Map enclosed as Figure 2.

5.6 Supplemental CTDEEP File Review

Eagle conducted a CTDEEP file review on March 12, 2019 for UST information, remediation files, manifest files, oil and chemical spill files, oil and chemical spill correspondences, soil vapor recovery, solid waste and any additional documents deemed relevant to the scope of this Phase I ESA. Eagle reviewed three (3) documents for the subject Site. A copy of each file isprovided in Appendix D


1. Underground/Aboveground U.L. Storage Tanks - September 23, 1988A correspondence between Riggott Manufacturing, Inc. and the Town of Mansfield Fire Marshal indicated the Site UST was inspected September 21, 1988 and found to be installed using the recommended installation practices of NFPA-30 and of Riggott Manufacturing and is fully warranted as is. Riggott Manufacturing manufactured the UST and Chem-Tech installed it on-Site.

2. Emergency Incident Report - January 20, 1989A release of #2 heating oil occurred at Southeast School in sand backfill of the new tank. Approximately 2-5 cubic yards of soil was removed to a landfill. No additional information was available to review.

3. Underground Storage Facilities Notification - November 20, 1991One (1) 10,000-gallon steel #2 fuel oil UST (Tank ID A1) was installed June 1955 on-Site. The 10,000-gallon UST A1 was replaced July 1988 by a 10,000-gallon sti-P3 #2 fuel oil UST (Tank ID A1R1). A Site plan was included with the notification indicating UST A1 was located within the same area as the current UST A1R1. See Section 8.2 for further detail on the location of UST A1.

5.7 Municipal File Review

Eagle conducted a Municipal Office review on March 12, 2019. Municipal offices researched as part of this Phase I ESA study include the Mansfield Assessor’s Office, Town Clerk, FireMarshal’s Office, Building Department, Public Works, Planning & Zoning, Facilities Department and Health Department. All municipal files are included in Appendix D.

5.7.1 Tax AssessorMansfield Tax Assessors property cards were reviewed and provided information regarding the parcel size and building layout, size and construction previously described in Section 2.0.

5.7.2 Building DepartmentEagle visited the Mansfield Building Department, but no pertinent or relevant records to the scope of this report were found for the subject Site.

5.7.3 Town ClerkEagle visited the Mansfield Town Clerk’s Office, but no pertinent or relevant records to the scope of this report were found for the subject Site.

5.7.4 Facilities DepartmentEagle visited the Mansfield Facilities Department and reviewed the following documents.

1. Service Station Equipment, Inc. - June 15, 2018A Cathodic Protection Monitoring Log indicated the 10,000-gallon UST located at the Site passed Cathodic protection testing.

2. Septic Suitability Report – January 26, 2010


A septic suitability study was conducted on-Site to determine the potential suitability to support an 800 student facility through data collection, field and laboratory testing, topographic surveying and preliminary subsurface waste absorption system (SWAS) calculations. Four (4) monitoring wells were installed north of the Site building around the turf fields. Groundwater was observed at depths from 45-58 feet below ground surface. Groundwater was observed to flow dominantly north towards the Fenton River and Mansfield Hollow Lake. Based on the observations of the Site and surrounding area, including topography, soils, and groundwater depths, the report concluded that the Site can adequately accept the wastewater flows of an 800 student facility.

5.7.5 Fire Marshal’s OfficeEagle visited the Mansfield Fire Department and reviewed one (1) underground storage facilitiesnotification consistent with the information discussed in Section 5.6.

5.7.6 Health DepartmentEagle visited the Eastern Highlands Health District and reviewed two (2) correspondence emails dated June 20, 2007 from the Connecticut Department of Public Health to Mr. Allen Corson of the Town of Mansfield indicating that Well #2 and #3 used for on-Site drinking water installed in the early 2000s were approved for public water supply use.

5.7.7 Planning & ZoningEagle visited the Mansfield Public Works and reviewed the following documents.

1. Topographic MapA topographic map provided by the Town of Mansfield Web GIS revealed detailed contours of the Site parcel. Based upon localized topography, a groundwater divide may exist on-Site with the northern portion flowing northerly and the southern more northwesterly towards Schoolhouse Brook and the Fenton River.

2. Wetland/Stream MapA wetland/stream map provided by the Town of Mansfield Web GIS revealed that wetlands and/or streams mapped by the National Wetland Inventory and Town Wetlands do not appear to exist on-Site.

3. Natural Diversity Database MapA natural diversity database map provided by the Town of Mansfield Web GIS revealed that the Site parcel appears to include natural diversity areas on the north, south, east and western parcel boundary lines.

5.7.8 Public WorksEagle visited the Mansfield Public Works and reviewed the following document.

1. Site Plan A Site Plan prepared by the Malmfeldt Associates Architects of Hartford, Connecticut (date unknown) revealed a preliminary Site sketch of the building and surrounding parcel. The septic system tank and leaching fields are located southeast of the Site


building, well #1 is located near or within the building foot print and an oil tank is said to be located just northeast of the boiler room within the pavement. See Section 8.2 for further detail on the location of UST A1.

5.8 Connecticut Transfer Act

Based on the information reviewed to date, in our opinion the Site does not meet the requirements set forth in the Connecticut Transfer Act to be considered an “Establishment” and, therefore, would not be subject to the legal and technical requirements of the Connecticut Transfer Act in the event of a transfer of ownership. Advise from legal counsel is suggested to confirm a final determination.


6.0 SITE AND AREA HISTORY

The Site and area history has been compiled from Sanborn Maps, City Directories, Historical Topographic Maps and Aerial Photographs of the Site.

6.1 Sanborn Fire Insurance Maps

Certified Sanborn® Fire Insurance Maps were unavailable for the Site due to the property being unmapped. Copies of the Sanborn Fire Insurance Map report are included in Appendix E.

6.2 Topographic Maps

Topographic maps were obtained via the EDR Topographic Map Library. Specific maps reviewed included the United States Geological Survey (USGS): Woodstock and Norwich 15-minute Quadrangle for the 1892, Woodstock 15-minute Quadrangle for the years 1915 and 1921,Spring Hill 7.5-minute Quadrangle for 1943 and Spring Hill and Willimantic 7.5-minute Quadrangle for 1945, 1953, 1970, 1983, 1984 and 2012. Copies of the topographic maps are included in Appendix F.

From 1892 to 1945, Site topography remained relatively consistent with higher elevation to the northeast and lower to the southwest.

In 1953, the southern adjacent parcel becomes developed for residential housing and the dam constructed by the Army Corps of Engineers is visible west of the Site, across Warrenville Road.

In 1970, the Site building is visible. Localized grading of the Site to facilitate the buildingis evident. The outline of the new Mansfield Hollow Lake is also depicted north of the Site.

In 1983 and 1984, Mansfield Hollow Lake appears fully developed (flooded) north of the Site.

In 2012, the Site and surrounding area appears as current conditions exist today. The Site is located at an approximate elevation of 275 feet above sea level.

6.3 Aerial Photographs

Aerial photographs were obtained via EDR through their Aerial Photo Decade Package sourced from CTMAGIC, USGS, USDA, MAGIC, FAIR, USGS/DOQQ and USDA/NAIP collections.Aerial photographs reviewed were for the years 1934, 1941, 1951, 1959, 1963, 1969, 1970,1974, 1980, 1986, 1990, 1991, 1995, 2005, 2008, 2012 and 2016. Copies of the aerial photographs are included in Appendix G.

Aerial photographs from 1934 to 1941, show the northeast and southwest portions of the Site appear to consist of cultivated agricultural fields. An apparent farmstead with several barns is located offsite, adjacent to the northwest.


The 1951 aerial photograph depicts some partial clearing of the site. The 1959 aerial photograph, depicts the current main sections (central and west) of the building near the western property boundary.

From 1963 to 1980, the Site appears to remain unchanged however, one (1) addition was added to the east side of the building in the late 1960s. In 1986, the turf fields north of the Site building appear.

From 1990 to 2016, the Site appears as current conditions exist today with the second addition added to east side of the building in the early 2000s.

6.4 City Directories

City directories were obtained by Eagle via EDR Digital Archive. City directories reviewed were from 1977, 1982, 1987, 1992, 1995, 2000, 2005, 2010 and 2014. Copies of the city directories are included as Appendix H.

In 1977, the subject Site is not listed.

From 1982 to 2014, the subject Site is listed as Southeast/Mansfield Public School District.


7.0 SITE RECONNAISSANCE

Ms. Kristi Gagnon and Ms. Taylor Carfiro performed visual observations of the subject propertyduring a Site Reconnaissance on March 12, 2019. The Site visit included walking around the property, entering the building and surveying the surrounding property area. The purpose of the Site reconnaissance was to observe current Site conditions and assess, based on visual observations, if there were release(s) of OHM to the surface or subsurface. Full inspection of theexterior portions of the Site property was inhibited by snow cover at the time of inspection. Pertinent Site characteristics are shown on the Site plan presented as Figure 3 and on photographs included in Appendix I.

7.1 Physical Setting

7.1.1 Site Setting and TopographyThe Physical Setting of the Site are discussed in Section 2.0 of this report and shown in Figure 1and Figure 2. The Site is generally flat with higher elevation to the east and located at an elevation approximately 275 feet above mean sea level. The Site is located on the “Woodstock,Norwich, Spring Hill and Willimantic 7.5, 15 and 30 Minute Quadrangle Series Topographic”maps. Based on the topographic maps, inferred groundwater flow direction is northwesterly/northerly towards Schoolhouse Brook that discharges to Mansfield Hollow Lake.

7.1.2 Groundwater CharacteristicsAccording to the CT DEEP Water Quality Classifications Map of Connecticut (2015), the Site isa GA, GAA groundwater classification area that may not meet current standards of the presumption that groundwater is suitable for drinking without prior treatment. The Site is also located in an area that contributes to a public supply well.

7.1.3 Geologic CharacteristicsAccording to the CT DEEP Surficial Materials Map of Connecticut (Stone 1992), the materials beneath the Site are mapped as sand and gravel overlying sand overlying fines. Sand and gravel is generally less than 20ft thick, horizontally bedded and overlies thicker inclined beds of sand which in turn overlie thinly bedded fines of variable thickness (deltaic deposits overlying lake-bottom sediment).

According to the “Bedrock Geological Map of Connecticut” (Rodgers, 1985), the bedrock underlying the Site is described as the Waterford Group. Bedrock is characteristically light to dark, medium-grained gneiss.

7.1.4 Potential Environmental ReceptorsBased on USGS topographic maps, the nearest natural surface water body is Schoolhouse Brook located approximately 400 feet west of the Site which discharges to the Fenton River and then Mansfield Hollow Lake. The Site is located in Flood Zone C (X); areas determined to be outside the 1.0% and 0.2% annual chance floodplain according to the Flood Insurance Rate Map for this area of Tolland County. A copy of the FEMA Map is included in Appendix J.

7.2 Physical Characteristics

The following is a list of observations made during the reconnaissance of the Site.


7.2.1 Land AreaThe land area for the Site was observed to be generally flat with higher elevation to the east. Adjacent parcels to the north and west sloped steeply down, away from the Site.

The 16.1-acre Site is located at 134 Warrenville Road in Mansfield, Connecticut. The Site is accessed via two (2) asphalt paved driveways off the east side of Warrenville Road. The Site is currently occupied by Southeast Elementary School. The Site is improved by one (1) single-story masonry building of approximately 34,594 square feet originally constructed in 1957. Two (2) additions were added to the east end of the school in the late 1960s in early 2000s.

The school building includes twenty-three (23) classrooms, one (1) multi-purpose room one (1) kitchen, four (4) custodial closets throughout the building, one (1) boiler room in the basement,several office areas and one (1) maintenance bay adjacent to the boiler room. The interior of the school appeared recently renovated with new floor covering and vinyl windows.

The Site includes 40,120 square feet of asphalt paving to the north and southwest around the building. The northern portion of the parcel includes three (3) turf fields, one (1) storage shed for equipment and one (1) concession stand with an independent septic system built in 2009. Asingle-story masonry block well pump house exists northeast of the Site building that houses storage and well equipment for the three (3) groundwater drinking wells located on-Site. Agreenhouse/storage shed also exists south the Site building with two (2) propane tanks for heating. A suspected septic system tank cover was observed south of the Site building with an associated leaching field area southeast of the Site building.

Warrenville Road (Route 89) borders the Site to the west and northwest. An Army Corps of Engineers Dam (Mansfield Hollow Dam) is located on the parcel, across the road, to the west of the Site. Forested land is located across the road to the northwest and southwest. Residential dwellings exist south of the Site. Forested land extends east, northeast and north from the site, extending to Mansfield Hollow Reservoir.

7.2.2 Site OperationThe Site currently operates as Southeast Elementary School housing approximately 150 studentsgrades Pre-K through Grade 4. The building utilizes twenty-three (23) classrooms. Science labs were not observed during the Site visit. One (1) multi-purpose room in the northwest corner of the building is used as the cafeteria, auditorium and gymnasium. One (1) kitchen exists east of the multi-purpose room. The boiler room is located within the only basement area including one (1) new and one (1) retired oil furnace. A maintenance bay for landscape equipment and extra storage is accessed from the exterior adjacent to the boiler room. Site operation has remained consistent since first constructed in 1957. Prior to Site development, the Site parcel appears to have been occupied by agricultural fields and forested land.

7.2.3 Petroleum Product and Raw Chemical StorageThe following petroleum and chemical storage was observed on-Site:

One (1) 10,000-gallon sti-P3 #2 heating oil UST adjacent to the northwest side of the Site building;One (1) self-contained diesel generator north of the Site entrance within a wood enclosure;Two (2) propane cylinders for greenhouse/storage shed heat;


One (1) 5-gallon diesel and one (1) 5-gallon gasoline steel containers in the maintenance bay;One (1) plastic bin of ice melt (approximately 200-lbs) was observed near the maintenance bay;Fuel and petroleum products within landscape equipment (tractor, snow blower and weed-wacker;De minimis quantity petroleum products and lubricants were observed within the boiler room area; and,De minimis quantity Hillyard Arsenal cleaners, strippers, soaps and disinfectants including (Top Clean 10, Citrus-Scrub, Suprox-D, Carpet pH Rinse, Extraction pH Rinse,Suprox-Multi-Purpose and Green Select Glass Cleaner) throughout each of the four (4) custodial closets, kitchen and nurse area. De minimis quantity penetrating spray (WD40) and adhesives were also observed within the custodial areas.

7.2.4 Petroleum and Chemical Waste Generation and DisposalPetroleum and chemical waste generation and disposal was not observed on-Site other thantypical solid waste disposal discussed in Section 7.2.8. Gasoline/diesel fuel is utilized as needed to refill landscape equipment and any waste oil from equipment is disposed in conjunction with the Town of Mansfield Public Works Facility.

7.2.5 Air Emission SourcesOne (1) chimney associated with the boiler room was observed on-Site. One (1) vent pipe was observed on the greenhouse/storage shed associated with the propane heater.

7.2.6 Wastewater Discharge SourcesNot observed on-Site other than floor drains discussed in Section 7.2.11.

7.2.7 Visual Indications of Contamination of Building InteriorSuspect petroleum staining (appeared de minimis in nature) was observed within the boiler room adjacent to the west wall. UST supply and return piping was observed at the north wall. De minimis petroleum/possible gasoline staining was observed below the tractor within the maintenance bay.

7.2.8 Solid Waste or Hazardous Waste Deposits Observed On-SiteTwo (2) hydraulic trash compactors exist on-Site north of the building within a wood enclosure on a concrete pad. The two (2) compactors were formerly located on a separate concrete pad closer to the Site building but were moved to the current location. Staining on or adjacent to the area of each compactor was not observed. Staining was also not observed on the former concrete pad.

7.2.9 On-Site Sources of Contamination Observed During Site VisitA de minimis petroleum sheen was observed within the catch basin located just north of the Site building within the asphalt parking lot. The source of the sheen is likely from sheetflow off the parking lot and typical, incidental vehicle discharges.

7.2.10 Dielectric Fluid-Containing Electrical Devices


One (1) concrete pad-mounted transformer exists at the north side of the building within a wood enclosure. No label indicating the presence or absence of PCB dielectric fluid was observed.Staining on or adjacent to the concrete pad was not observed.

7.2.11 Floor Drains, Dry Wells, Pits, Sumps or LagoonsFour (4) floor drains were observed within each custodial closet. One (1) floor drain was observed within the boiler room and one (1) within the kitchen area. Staining on or adjacent to the area of each drain was not observed.

7.2.12 Asbestos Containing Materials (ACMs)An ACM inspection was not included as part of this Phase I ESA, however, suspect ACM may exist within the pipe tunnels below the school and within inaccessible areas (above ceilings/behind walls). The Site building appeared to have been recently renovated with new floor tile.

7.2.13 Off-Site Sources of Contamination Observed During Site VisitNo offsite sources of potential contamination were noted.


8.0 INTERVIEWS

8.1 User

The User is typically interviewed about their knowledge of the Site during the Phase I ESA study. The User of the report, Town of Mansfield, referred Eagle to the User Questionnaire discussed in Section 3.0 of this report.

8.2 Key Site Manager

Mr. Allen Corson, Director of Facilities Management Department for the Town of Mansfieldwas identified as the “Key Site Manager” and was interviewed by Eagle on March 12 and 14,2019. Information gathered through interview with Mr. Corson is as follows:

A Septic System Study was conducted in 2010;

A 10,000-gallon #2 heating oil UST (A1R1) exists on-Site; and

The former 10,000-gallon #2 heating oil (A1) was reportedly located within the same area as the current UST when the UST’s were exchanged during a renovation project in the early 1990s.

8.3 Interview with State and/or Local Officials

Various City officials were interviewed on March 12, 2018. No additional or pertinent information was found related to the subject Site.

8.4 ASTM Environmental Questionnaire

In addition to an interview with the Site User, an ASTM environmental site assessment questionnaire was also completed by Mr. Corson, as well as the Eagle personnel that completed the Site Reconnaissance, and can be found in Appendix A. The questionnaire did not provide additional information of environmental significance that was not already addressed during the Site Reconnaissance.


9.0 DATA GAPS

Eagle identified one (1) significant data gap, as defined by ASTM E1527-13, during the Site reconnaissance and records review that would significantly affect the ability of Eagle to identify recognized environmental conditions in connection with the Site.

One (1) former 10,000-gallon heating oil UST (Tank ID A1) was reportedly located within the same area as the current UST and removed from the ground June 1, 1988. No additional information was available to review. Specifically, a closure report or analytical summary of soil and/or groundwater results from the tank removal activity was not observed at the Town of Mansfield Municipal Departments or at CTDEEP at the time of this report.


10.0 VAPOR ENCROACHMENT SCREENING

10.1 Vapor Encroachment Screening

In 2010, ASTM international issued its revised Standard E2600-10 entitled “Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions.” This standard guide has been adopted into the ASTM E1527-13 Phase I Environmental Site Assessment Standard. The purpose of the standard is to define good commercial and customary practice for real estate transactions in the United States for conducting a screening assessment directed solely at the likelihood for migrating vapors to encroach upon a target property (i.e. the Site) creating a vapor encroachment condition (VEC). The presence of vapors in a building that has migrated from a release to the environment (i.e. from a release outside of the building) can result in CERCLA liability. Thus, this screening serves to assess the likelihood of a VEC. Determining whether or not encroaching vapors result in a vapor intrusion problem requiresfurther investigation that is beyond the scope of the standard.

A VEC is defined as the presence or likely presence of chemicals of concern (COC) vapors in the subsurface of the Site caused by the release of vapors from contaminated soil or groundwater on or near the Site. An area of concern (AOC) as defined in the E2600-10 is measured 0.33-miles from the Site for known or suspect contaminated sites with volatile organic compound (VOC) or semi-VOCs; 0.1-mile from the Site for known or suspect petroleum hydrocarbon releases. The identification of AOCs may be reduced if the groundwater flow direction is known relative to the Site. Critical distances are taken into account for contaminated groundwater plumes in any direction for COCs including petroleum light non-aqueous phase liquid (LNAPL) accumulating above the water table at a distance of 100 ft. from the edge of the plume to the Site and 30 ft. for dissolved volatile petroleum hydrocarbons.

A Vapor Encroachment Screen (VES) was obtained by Eagle via EDR. Based on this VEC assessment, and the Site reconnaissance, there is low potential that a VEC exists at the Site based upon a lack of documented releases within the area and current and historic chemical utilization/storage on and off-Site. A copy of the VES report is provided in Appendix K.


11.0 FINDINGS

Based on the information compiled in this Phase I ESA, Eagle offers the following pertinent findings for the Site:

The Site consists of one (1) parcel of land totaling 16.1-acres;

The Site is improved by one (1) single-story masonry building of approximately 34,594square feet originally constructed in 1957. Construction consists of slab-on-grade with a basement boiler room and pipe tunnels, masonry framing, pitched and flat roofing and a septic system. Two (2) additions were added to the east end of the school in the late 1960s in early 2000s. Construction consists of slab-on-grade, masonry/wood framing and flat roofing. The Site includes 41,500 square feet of asphalt paving to the north and south of the building. An approximate 600 square foot concession stand with a bathroom was constructed in 2009 northeast of the Site building. Construction consists of slab-on-grade, wood framing, pitched roofing and an independent septic system. A storage shed, greenhouse/storage shed and a masonry block well pump house also exists on-Site;

The school building includes twenty-three (23) classrooms, one (1) multi-purpose room (cafeteria, gymnasium & auditorium), one (1) kitchen, four (4) custodial closets throughout the building, one (1) boiler room in the basement and one (1) maintenance bay adjacent to the boiler room. Approximately 150 students, grades Pre-K through 4th

grade, utilize the building with associated faculty;

The Site is currently occupied by Southeast Elementary School. Historically, the Site was utilized for agricultural fields with mixed raw land until the Site building was constructed in 1957. Additions were constructed in the late 1960s and early 2000s;

The Site building utilizes an on-Site septic system, onsite water supply wells, and #2 fuel oil for heating;

One (1) approximate 10,000-gallon sti-P3 #2 heating oil underground storage tank (UST) exists on the north side of the school building. The UST was installed 07/01/1988 and has exceeded the thirty (30) year life expectancy of sti-P3 USTs. A former 10,000-gallon heating oil UST was reportedly located within the same area and removed from the ground 07/01/1988;

One (1) backup generator with a self-contained diesel tank exists north of the school within a wood enclosure. Staining on or adjacent to the generator was not observed;

One (1) concrete pad-mounted transformer exists north of the school within a wood enclosure. No label indicating the presence or absence of PCB containing di-electric fluid was observed;


The Site is listed on the CT UST, SPILLS and FINDS databases contained in an EDR environmental database report for two (2) recorded USTs and a release of 2-gallons of #2 fuel oil in 2015;

There is low potential that a vapor encroachment condition (VEC) exists at the Site based upon a lack of documented releases within the area and current and historic chemical utilization/storage on and off-Site;

An ACM inspection was not included as part of this Phase I ESA, however, suspect ACM may exist within the pipe tunnels below the school and within inaccessible areas (above ceilings/behind walls). The Site building appeared to have been recently renovated with new floor tile; and,

The Site does not appear to qualify as an “Establishment” as defined by the Connecticut Transfer Act due to a lack of observed evidence that on or after November 19, 1980 the Site generated more than one hundred (100) kilograms of hazardous waste in any one month. Advice from legal counsel is suggested to confirm a final determination.


12.0 CONCLUSIONS

Eagle has performed a Phase I Environmental Site Assessment in general conformance with the scope and limitations of ASTM Practice E1527-13 at Southeast Elementary School located at 134 Warrenville Road in Mansfield, Connecticut (depicted on Figure 3). Any exceptions to, or deletions from, this practice are described in Section 14.0 of this report.

This assessment has revealed evidence of two (2) historic and one (1) recognized environmental conditions in connection with the Site at the time of this report.

HREC No. 1: Septic System Leaching FieldsSoutheast Elementary School was constructed in 1957 with an on-Site septic system and leaching fields located southeast of the building. If halogenated solvents (commonly found in floor strippers and cleaners prior to 1980) or other products potentially containing contaminant compounds were previously used in the building, the constituents and residual rinse water may have been disposed of into the septic system with potential to impact soil and/or groundwater within the vicinity of the leaching fields.

HREC No. 2: Underground Storage Tank A1One (1) former 10,000-gallon heating oil UST (Tank ID A1) was reportedly located within the same area as the current UST and removed from the ground 07/01/1988. No additional information was available to review. Specifically, a closure report or analytical summary of soil and/or groundwater results from the tank removal activity was not observed at the time of this report. Should a release of fuel oil have occurred, there is potential for an impact to soil and/or groundwater unless official documentation can prove a release had not occurred.

REC No. 1: Underground Storage Tank A1R1One (1) 10,000-gallon sti-P3 #2 fuel oil UST (Tank ID A1R1) exists on-Site north of the building. The UST was installed 07/01/1988 and has exceeded the thirty (30) year life expectancy of sti-P3 USTs. Mansfield Facilities Department provided a copy of the cathodic protection monitoring log dated June 15, 2018 indicating the UST passed testing. It is unclear however, if just the UST was cathodically tested or if the return/supply piping was included. Until the UST is removed from the ground, or abandoned in place, there is potential for a release to soil and/or groundwater within the vicinity of the UST and associated piping.


13.0 RECOMMENDATION

Based on the findings and conclusions discussed herein, Eagle offers the following recommendations:

Eagle recommends conducting a Phase II Environmental Site Investigation (ESI) to assess the presence of a release of regulated substances to soil and/or groundwater at the Site to address the one (2) HRECs and one (1) REC observed in connection with the property.

Eagle also recommends the timely removal and replacement of the underground storage tank (UST) A1 and associated piping due to the exceedance of the thirty (30) year life expectancy.Prior to any tank removal activities, thirty (30) day notification is required by the Connecticut Department of Energy and Environmental Protection (CTDEEP) as well as any applicable permits through the Town of Mansfield.

1.0 Introduction

In accordance with your authorization, Sub-Surface, LLC. (SS) reports to you the results of the ground penetrating radar survey performed on March 14, 2019 at 134 Warrenville Road, Mansfield, CT. This survey directed by your approval of SS quotation #1.6901.19 dated March 8, 2019.

1.1 Purpose and Scope

The purpose of the ground penetrating radar survey was an investigation for the location of underground storage tank and sub surface features associated with leaching field (Southeast Elementary School),

Above image shows site map provided by the Eagle Environmental, Inc.

2.0 Geophysical Survey

Sub-Surface, LLC performed the geophysical survey. A transducer operator/supervising GPR technician performed the survey.

2.1 Geophysical Survey Procedures

The depth setting of the GPR survey was approximately 10.00’ to locate any existing and unknown anomalies. An increase of high conductivity was located approximately 0.00’ to 05.25’ below the surface. The increase in conductivity is commonly caused by the capillary fringe of the water table, clays, silts, or organics. GPR traverses were conducted with a maximum of a 12.00’ spacing to better conduct the GPR survey. Traverses were conducted in both north/south and east/west directions to form a grid pattern. Traverses were conducted around all surface obstructions such as snow banks, standing water, curbs, fence, walls, etc. All depths are approximate based on an estimation of the dielectric constants of the subsurface.

The following is an explanation of the equipment used during our survey:

1. The equipment used to conduct the geophysical survey included GPR equipment, which consists of subsurface interface radar (SIR-3000) computer manufactured by Geophysical Survey Systems, Inc., power supply, graphic recorder, video display unit, and transmitting/receiving antenna. The equipment is known collectively as a GPR system. The transmitting/receiving antenna transmits electromagnetic signals into the subsurface and then detects, amplifies and displays reflections of the signal on a graphic recorder and a video display unit. As the antenna is moved slowly across the ground surface or surface of contact, a radar image of the subsurface is produced. The maximum depth of penetration of the GPR signal and the resolution of the reflections are a function of the antenna frequency and the electrical properties of the subsurface. As electrical conductivity of the subsurface increases, GPR signal penetration decreases. GPR reflections are produced by spatial changes in the physical properties of the subsurface (I.e., type of material, presence of any subsurface fluid and porosity) and related changes in the electrical properties of the subsurface material in the path of the signals. The greater the difference in the subsurface structures the stronger the GPR reflection seen in the data. Characteristics that are considered in the interpretation of the GPR data from a given site include the size, shape, and amplitude of the reflections. Metallic underground storage tanks (UST’s), utilities and conduits have electrical properties uniquely different from those of the soils in which they are buried. As a result, the GPR reflections are usually of high amplitude and have distinctive shapes. For GPR profiles oriented perpendicular to the long axis of the tanks, the signature is similar to a hyperbola. The signature is also a function of the tank diameter.

SAMPLE PHOTO: above represents a sample of data collected by Sub-Surface Informational Surveys, Inc. on Sept. 15, 2004 at a site in the State of CT. It shows three (3) Underground Storage Tanks (UST’s) with the centerline at the top of the parabolas. This data was taken through concrete, with rebar. NOTE: The above is not part of the data collected for this survey.



2. Pipehorn 500 Dual-Transmitter, Dual-Frequency Locator: This unit has two separate transmitters. One operates at the highest frequency available in sweeping an area of tracing poor conductors such as iron pipes, fiber optic cable w/tracer tape. A second, low frequency transmitter enables us to quickly isolate a single conductor in congested areas, or to trace for a long distance. NOT IMPLEMENTED 3. The Verifier G2: This unit provides digital signal processing for a variety of applications. The unit offers Active, Passive and Beacon locating modes. The unit transmits via direct line connections, induction clamp or induces broadcast signals. An 80 kHz frequency facilitates locating metallic lines with insulators that weaken or block low frequencies. In passive mode, detects signals generated by 50/60 HZ power as well as radiated radio frequencies. NOT IMPLEMENTED

2.2 Geophysical Survey Results

A Ground Penetrating Radar (GPR) survey was conducted in two (2) specific grass, snow, and concrete covered areas located at 134 Warrenville Road as directed by the Eagle Environmental, Inc. project manager. The first area was just north of the building for the location of underground storage tanks (UST). The location of GPR anomalies consistent with one (1) possible suspect underground storage tank were detected in the GPR data collected in the second survey area south of building and marked on the ground with paint on the day of the survey. The location of GPR anomalies consistent with possible suspect underground leach fields were detected and marked with paint on the day of the survey (as seen below).

Above photo shows survey area with the location of detected GPR anomalies consistent

with a possible suspect underground leach field marked with paint as directed by the Eagle Environmental, Inc. project manager.



The above and below photos show survey area where parabolic anomalies consistent with an underground storage tank were detected in the GPR data and marked on the ground with paint on the day of

the survey.



Above image shows GPR data collected while traversing survey area pictured below. GPR anomalies consistent with possible suspect underground storage tank can be seen starting at 99.94’ into the

GPR data at an approximate depth of 02.90’’. The location of the detected anomalies were marked with pink paint on the day of the survey as seen below.



Above image shows GPR data collected while traversing grass covered survey area on south side of building pictured below. GPR anomalies similar to the long axis of a possible suspect underground leach field can be seen starting at 346.56’ into the GPR data at an approximate depth of 04.84’. The location was

marked with on the day of the survey.

APPENDIX H

DRINKING WATER NOTIFICATIONS

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER March 29, 2019

No action is required by consumers as a result of this issue

Eagle Environmental Inc., is currently performing an environmental study at Southeast School as we look to identify a suitable location to serve all elementary students. During the course of their study Bromomethane was detected at 0.94 ppb from a raw well sample. Additional follow up samples are being collected today. Although the EPA has not established a maximum contaminate level (mcl) for this compound and there is currently no standard health effects language listed for public notification for Bromomethane, we felt it was important we share this information with you. For the purposes of water quality regulations Bromomethane is tested at the point of entry not from the raw well. Samples taken from the entry point are indicative of what the children consume. As required by the Connecticut Department of Public Health (DPH), Southeast School had sampled volatile organic chemicals quarterly from the point of entry and results have been non-detect for two years. Due to no detections of volatile organic chemicals, DPH has recently reduced the requirement for Southeast School to annual. Bromomethane results for the past two years are outlined below:

Date Result February 26, 2019 < 0.5 ppb November 18, 2018 < 0.5 ppb August 3, 2018 < 0.5 ppb April 2, 2018 < 0.5 ppb February 20, 2018 < 0.5 ppb October 16, 2017 < 0.5 ppb August 1, 2017 < 0.5 ppb April 3, 2017 < 0.5 ppb

Finally, we want you to be assured that your water is tested on a continuous basis as required by the Connecticut Department of Public Health and that all parameters tested meet state and federal compliance guidelines.
