1.0 INTRODUCTION

ATC Group Services LLC (ATC) by virtue of its acquisition of Environmental Compliance Services

(ECS) on October 17, 2016, has prepared this Site Monitoring Report summarizing the 2016 annual

groundwater monitoring event conducted on 22 November 2016 at the Osornio Residence (hereafter

referred to as the “Site”). The Site is located at 2284 Sims Hill Road in Lemington, Vermont (Figure 1).

The original spill consisted of a release of approximately 100 gallons of fuel oil from two above ground

storage tanks (ASTs) that reportedly occurred over several days. The spill was reported to the Vermont

Department of Environmental Conservation (VT DEC) on 23 August 2005, with initial response and

investigations performed by Engel Environmental Services, Inc. (EES).

Field work was performed in accordance with the ATC work plan dated 28 October 2016 and included

installing a replacement well for MW-3, collecting one groundwater sample from the replacement well,

and collecting one water supply sample. The scope of work was performed at the request of Mr. James

Donaldson of the VT DEC and approved by Ms. Lisa Osornio’s insurance (Vermont Mutual Insurance

Co.) in an email dated 1 November 2016.

1.1 SITE DESCRIPTION AND PHYSICAL SETTING

The Site consists of a private residence that is located in a rural setting on a small mountain (Figure 2).

The property is not used as a primary residence. The property uses a private water supply well and septic

system. The two former ASTs were located on a 6’ X 5’ dirt portion of the basement in the southwest

corner. The remaining basement flooring material is concrete. The residence is currently heated with fuel

oil stored in two ASTs located adjacent to the former ASTs.

According to the Vermont Agency of Natural Resources Internet Mapping Site of Private Wells, no

private water supply wells are located within a ½-mile of the Site other than the well serving the property.

The residence is located on a small mountain that rises out of the Connecticut River Valley. The average

slope between the residence and the Connecticut River (approximately 1.6 miles east) is eight percent.

The water supply well is a shallow dug well, located approximately 60 feet down slope from the

residence. The property is bordered by Sims Hill Road to the south and east. The area to the north and

west is forested.

1.2 SITE HISTORY

EES completed an Initial Site Investigation (ISI) on 13 September 2005, following the release of

approximately 100 gallons of fuel oil in the basement. During the ISI, EES completed six soil borings in

the basement and two borings outside the residence. Soils were screened by EES personnel with a

photo ionization detector (PID). Concentrations in the basement were reported as high as 528 parts per

million (ppm). Soils screened outside the residence were reported at 0.0 ppm.

On 30 August 2006, EES supervised the completion of five soil borings and installation of monitoring

well MW-1 by Mike’s Boring & Coring of Barre, VT. Borings were advanced with a hollow stem auger.

Soil samples were screened by EES personnel with a PID; all soil headspace readings were less than 0.1

ppm. A water sample was collected from MW-1 and submitted for laboratory analysis of volatile organic

compounds (VOCs) by EPA Method 8260B and total petroleum hydrocarbons (TPH) by EPA

Method 8015. A sample collected from the water supply well was submitted for laboratory analysis for

VOCs by EPA Method 524.2 and TPH by EPA Method 8015. There were no VOC or TPH detections

above laboratory reporting limits in the water samples collected from MW-1 or the water supply well.

Project No. 08-220825.01

February 7 2017


Page 2

EES returned to the property in May 2007 to collect additional soil and groundwater samples. One soil

boring was advanced in the basement; PID readings ranged from 3.4 ppm to 127 ppm in the 2.5 to 4.5 feet

below ground surface (bgs) interval. A groundwater sample was collected from MW-1 and the water

supply well and analyzed for the presence of VOCs. Samples collected from MW-1 and the water supply

well were below laboratory reporting limits. Indoor air monitoring was performed using a PID; all PID

readings were 0.0 ppm in the ambient air.

On 26 November 2013, ECS personnel supervised the completion of five soil borings (S-2 through S-6)

and subsequent installation of three monitoring wells (MW-3 through MW-5) to characterize contaminant

conditions at the Site and to supplement investigation data previously collected by EES. Monitoring

wells MW-4 (S-4), MW-5 (S-5), and previously installed MW-1 are located in the presumed down

gradient direction of the former ASTs. Monitoring well MW-3 (S-3) was installed in the source area.

Soil borings S-2 and S-6 were installed in the basement and are located to the north and south of the

plume, respectively. No monitoring wells or borings were installed upgradient of the former ASTs due to

space limitations.

During the advancement of soil borings on 26 November 2013, the highest soil headspace PID reading of

140.8 ppm was recorded in a soil sample collected at 0 to 3 feet bgs in S-3/MW-3, located in the spill

source area. Soil headspace PID readings in borings S-2, S-4/MW-4, S-5/MW-5, and S-6 were reported

between 0.1 and 0.8 ppm.

During drilling activities, groundwater was encountered between four and six feet bgs in the basement.

The native soils generally consisted of sand and gravel with trace amounts of silt.

Groundwater samples were collected on 30 May 2014 from monitoring wells MW-3, MW-4, and MW-5

and analyzed for the possible presence of VOCs via EPA Method 8021B. A water supply well sample

was collected from the kitchen sink and analyzed for the possible presence of VOCs via EPA

Method 524.2.

Naphthalene was detected in the sample collected from monitoring well MW-3 at 138 micrograms per

liter (µg/L) which is above the VGES of 20 µg/L. Ethylbenzene, total xylenes, and total

trimethylbenzene concentrations were detected in the water sample from MW-3, at concentrations

reported below their respective VGES. VOCs were not detected above laboratory reporting limits in

monitoring wells MW-4, MW-5, or the water supply well.

On 20 January 2015, ECS installed a soil vapor barrier and backfilled an area in the basement where the

two former heating oil ASTs were located. The installation of a soil vapor barrier was recommended to

mitigate potential vapor intrusion concerns and approved by the VT.

Prior to backfilling the former AST location, ECS personnel leveled the existing earthen area and crimped

an old copper fuel oil hose below grade. A soil vapor barrier consisting of two layers of 6 millimeter

polyethylene sheeting was placed over the former AST location. Source area monitoring well MW-3 was

inadvertently abandoned by ECS prior to installing the vapor barrier. After the soil vapor barrier was

installed, approximately half a cubic yard of ¾ inch gravel was applied and compacted. The area was then

topped with concrete flush to grade. Upon completion of the work, the ambient air in the basement was

screened using a PID. No PID readings were reported above background concentrations and no fuel oil

odors were observed in the basement of the house at the time of monitoring.

2.0 SITE MONITORING ACTIVITIES 2.1 MONITORING WELL INSTALLATION

On 22 November 2016 ATC installed a replacement well (MW-3R) immediately adjacent to the former

AST location (source area) to preserve the vapor barrier (Figure 2). The replacement well was installed to a

depth of approximately six feet bgs using portable drilling equipment after coring the existing concrete

surface. The highest PID reading was detected at 1.3 ppm at approximately three feet bgs. The well is

constructed of 1” PVC and protected at the surface with a flush-mounted road box. The boring log for MW-

3R is included in Appendix A.

2.2 PID SCREENING

During the November 2016 monitoring event, a PID was used to screen the ambient airspace within the

basement of the Osornio residence; all PID readings were 0.0 ppm within the basement.

2.3 GROUNDWATER CHARACTERISTICS

A majority of the soil boring and monitoring wells are located in the basement; therefore, a survey of the

monitoring wells has not been completed and groundwater elevations cannot be defined. Based on soil

screening results and site topography, groundwater is presumed to flow east-northeast. The vertical

groundwater flow components at the Site and the hydraulic relationship between the shallow unconfined

aquifer and the bedrock aquifer are currently unknown.

Water levels were measured in monitoring well MW-3R on 22 November 2016 and in monitoring wells

MW-4 and MW-5 on 18 January 2017. Depths to groundwater range from 2.7 feet below top of casing

(TOC) in MW-5 to 3.66 feet below TOC in MW-3R (Table 1). A contaminant distribution map with the

presumed groundwater flow direction is illustrated in Figure 3.

2.4 GROUNDWATER SAMPLING AND ANALYSIS

One groundwater sample was collected on 22 November 2016 from monitoring well MW-3R and

analyzed for the possible presence of VOCs via EPA Method 8021B. A water supply well sample was

collected on 18 January 2017 from the kitchen sink and analyzed for the possible presence of VOCs via

EPA Method 524.2.

Prior to groundwater sample collection, the monitoring well was purged using a disposable bailer and

drop line in accordance with ATC standard protocols. Purge water was discharged directly to the ground

outside the residence. The water supply well sample was collected after allowing the water to run for

approximately ten minutes prior to sample collection.

Naphthalene was detected in the groundwater sample collected from monitoring well MW-3R at 24.2

micrograms per liter (µg/L) which is above the VGES of 20 µg/L. Ethylbenzene, total trimethylbenzene,

and total xylenes concentrations were detected in MW-3R but at concentrations below their respective

VGES. VOCs were not detected above laboratory reporting limits in the water supply well.

All samples were transported under chain-of-custody in an ice-filled cooler to Eurofins Spectrum

Analytical, Inc. of Agawam, Massachusetts. The trip blank and duplicate samples were collected for

quality assurance/quality control (QA/QC) purposes. Analytical results of the duplicate sample, collected

from MW-3R, were all within the EPA guideline value of thirty percent. Petroleum-related compounds

Project No. 08-220825.01

February 7 2017

were not detected in the trip blank. Analytical results are summarized in Table 2 and illustrated in Figure

3. Laboratory analytical reports are presented in Appendix B.

3.0 CONCLUSIONS AND RECOMMENDATIONS

Based on the above findings, it is the opinion of ATC that the Site does not meet the criteria for a Sites

Management Activity Closed (SMAC) designation, unless a Notice to Land Record is applied to the

property deed. A Notice to the Land Record would be required due to VOC concentrations that exceed

the VGES in monitoring well MW-3R.

ATC recommends the following:

1. Annual groundwater monitoring with samples collected from one onsite monitoring well (MW-

3R) analyzed for VOCs by EPA Method 8021B and the water supply well analyzed by EPA

Method 524.2. Note: Prior to collecting a groundwater sample at MW-3R, an attempt will be

made to remove silt from the well using a pump in order to minimize sample turbidity. The next

groundwater monitoring event should be scheduled for fall 2017. If concentrations fall below the

VGES, the Site may be eligible for SMAC designation without a Notice to the Land Record.

2. Prepare a report to include water-quality analytical results, figures showing groundwater flow

direction and contaminant distribution, relevant tables, time-series graphs, laboratory reports, and

recommendations for further action.

Notes and Definitions

RPD Relative Percent Difference

dry Sample results reported on a dry weight basis

Not ReportedNR

Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to

document laboratory performance.

Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.

Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample

preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.

Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample

processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank

is used to document contamination resulting from the analytical process.

Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence

that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the

analyte.

Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and

accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest

non-zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes

into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample

RDLs are highly matrix-dependent.

Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical

process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and

samples prior to analysis. Percent recoveries are calculated for each surrogate.

Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic

intervals. Concentrations, intervals, and criteria are method specific.

Notes and Definitions

Analyte is found in the associated blank as well as in the sample (CLP B-flag).B

The method blank contains analyte at a concentration above the MRL, however no reportable concentration is present in

the sample.

Not ReportedNR

Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to

document laboratory performance.

Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.

Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample

preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.

Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample

processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank

is used to document contamination resulting from the analytical process.

Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence

that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the

analyte.

Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and

accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest

non-zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes

into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample

RDLs are highly matrix-dependent.

Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical

process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and

samples prior to analysis. Percent recoveries are calculated for each surrogate.

Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic

intervals. Concentrations, intervals, and criteria are method specific.
