1.0 INTRODUCTION
Kleinfelder, on behalf of ExxonMobil Environmental Services Company (EMES), has prepared this
Phase IV Completion Statement, Remedy Operation Status (ROS) Opinion, and Substantial
Hazard Evaluation (SHE) for former Mobil Service Station No. 01-JE4 located at 99 Worcester
Road in Natick, Massachusetts, associated with the Release Tracking Number (RTN) 3-0715 (the
site). Refer to Figure 1 for the regional location and Figures 2 through 8 for pertinent site features.
This report has been prepared in accordance with the applicable provisions of the Massachusetts
Contingency Plan (MCP), 310 CMR 40.0000. The Phase IV activities have been completed
pursuant to the provisions set forth in 310 CMR 40.0800 for Comprehensive Response Actions.
The continued operation, maintenance and monitoring of the Comprehensive Remedial Alternative
(enhanced bioremediation using BOS 200® followed by monitored natural attenuation (MNA)) will
be conducted at this site under the ROS provisions set forth in 310 CMR 40.0890 for the purpose
of achieving a Permanent Solution. A SHE has been conducted in support of the ROS to
demonstrate that a condition of No Substantial Hazard exists at the site.
1.1 Background and Regulatory Status
The information in the following section was obtained directly or summarized from the Revised
Class C-1 RAO Statement submitted by Camp, Dresser, and McKee, Inc. (CDM) in December
2009.
Amoco reported petroleum-affected soil and groundwater to the Massachusetts Department of
Environmental Protection (MassDEP) following a subsurface investigation in November 1986. The
MassDEP listed the site as a Location To Be Investigated on January 15, 1990 and issued Mobil
a Notice of Responsibility on May 29, 1991. On July 15, 1991, the site was listed as a Non-Priority
Confirmed Disposal Site with MassDEP RTN 3-0715 assigned to the site.
On May 28, 1991, an Interim Measure was approved by the MassDEP involving the installation,
implementation, and operation of a groundwater recovery and treatment system and a soil vapor
extraction (SVE) system. In May 1992, Mobil was granted a Waiver of Approvals by the MassDEP.
Mobil received a “Notice of Audit: Request for Information” letter from the MassDEP on February
28, 1994 indicating a violation because the Request of Information response was past the 30-day
deadline. No further action was taken.
135659/FRM16R48263 Page 2 of 18 October 18, 2016
On May 7, 1997, the Waiver of Approvals expired.
In 1999, Groundwater & Environmental Services Inc. (GES) conducted a MassDEP database
search and file review and determined that an RAO for the subject property was completed by
LandTech Remedial in September 1997 but never submitted to MassDEP. In 2001, CDM
conducted another MassDEP file review and found no evidence of the LandTech RAO submittal.
On February 20, 2000 GES submitted a Tier II Extension Request to MassDEP.
GES detected 2.64 feet of light non-aqueous phase liquid (LNAPL) in monitoring well OW-7.
MassDEP was notified of the 72-hour reportable condition on February 25, 2000 and MassDEP
issued RTN 3-19321 to the site. On April 21, 2000, GES submitted an Immediate Response Action
(IRA) Plan to gauge and bail monitoring well OW-7 to recover detected LNAPL. IRA Status
Reports were submitted by GES on June 28 and December 28, 2000, and Parsons submitted an
IRA Status Report on April 9, 2001.
Parsons submitted a Phase II Scope of Work on April 9, 2001 and a Tier II Extension request on
May 23, 2001 to the MassDEP.
On September 4th, 2001 CDM submitted a Phase I Initial Site Investigation and a Tier
Classification with a score of 202 resulting in a Tier II Classification for the site.
CDM submitted an IRA Amendment in October 2001 and IRA Status Reports in October 2001,
April and October 2002, April and October 2003. An IRA Completion Report was submitted on
April 12, 2004 to the MassDEP.
In January 2002, CDM submitted a Phase II Comprehensive Site Assessment (CSA). A Revised
Phase II CSA and a Phase III RAP were submitted on July 21, 2004 to the MassDEP. The Phase
II revision was to correct the groundwater classification from GW-2/GW-3 to GW-1. Enhanced in-
situ bioremediation was determined as the most effective remedial alternative in the Phase III RAP.
In July 2004, a Phase IV RIP was submitted to the MassDEP by CDM proposing the use of Oxygen
Release Compound (ORC®) as the approach to remediate the elevated levels of gasoline
constituents in the site’s groundwater. In July 2004, CDM oversaw the injection of ORC® into the
subsurface. CDM submitted a Phase IV Final Inspection Report (FIR) and Completion Report,
and Phase V ROS submittal in August 2004.
135659/FRM16R48263 Page 3 of 18 October 18, 2016
To maintain ROS, CDM submitted Inspection and Monitoring Reports in February, August 2005,
and February 2006. In August 2006, CDM submitted a Class C-1 RAO Statement to the MassDEP,
based on the determination that a Temporary Solution and condition of No Substantial Hazard had
been achieved for the site, and that a Permanent Solution was not currently feasible. CDM
concurrently submitted a Final Phase V Inspection Monitoring Report to the MassDEP with the
submittal of the Class C-1 RAO.
In September 2008, MassDEP was notified of LNAPL detected in monitoring well OW-7. MassDEP
did not issue a new RTN but gave verbal approval of the IRA Plan involving weekly gauging and
bailing of the LNAPL. Weekly events included gauging and bailing of OW-7 as well as gauging of
ten on-site wells. LNAPL in OW-7 decreased from 0.37 feet to 0.01 feet within the first three weeks
with no measureable product detected for the four subsequent weeks of gauging. Additionally,
LNAPL was not detected in any of the 10 on-site wells.
In November 2008, an IRA Modification Plan was submitted modifying the gauging frequency from
weekly to bi-weekly by CDM. IRA Status Reports were submitted January and July 2009 and an
IRA Completion report was submitted in December 2009 by CDM.
CDM submitted Post Class C RAO Status Reports to the MassDEP in June and December 2010,
and June 2011.
Kleinfelder submitted Class C-1 Post Response Action Outcome (PRAO) Status Reports on
December 9, 2011 and June 18, 2012.
On July 16, 2012, Kleinfelder retracted the Class C RAO and submitted a Phase III RAP, Phase
IV RIP, and Tier II Extension. The Phase IV RIP outlined plans for the application of ISCO as an
alternative and more aggressive approach to achieve a Permanent Solution at the site.
Kleinfelder submitted a Phase IV Completion Statement, and ROS with Substantial Hazard
Evaluation (SHE) on January 7, 2012. The Phase IV Completion Statement detailed the
implementation of ISCO at the site, and summarized the results of the Comprehensive Response
Action which met performance standards for ROS.
Kleinfelder submitted ROS status reports in May 2013, December 2013, June 2014, January 2015,
and July 2015 summarizing groundwater monitoring activities and evaluating ROS.
135659/FRM16R48263 Page 4 of 18 October 18, 2016
In October 2015 Kleinfelder submitted a ROS Termination, Phase III RAP, Phase IV RIP, and Tier
II Extension selecting the Comprehensive Response Action of enhanced bioremediation using
BOS 200 ® followed by MNA and detailing its implementation. In March 2016 Kleinfelder submitted
a Phase IV RIP Status report summarizing monitoring well repairs conducted during the reporting
period and proposing a schedule for implementing the selected remedial alternative.
1.2 General Site Description and Use History
The subject property is located on the Town of Natick Assessor’s Map 21, Lot 309. The property
is currently owned and operated by Jiffy Lube as an automotive service facility. The site is
approximately 0.15 acres on the northern side of Worcester Road (Route 9), refer to Figures 1 and
2 for site and surrounding features. The subject and surrounding properties are zoned for business
use.
The site is improved by a single story building currently operated as a Jiffy Lube service facility.
The majority of the property is paved with landscaped areas along the eastern, southwestern, and
northwestern perimeters of the property. A landscaped area is also located southwest of the site
building. The property is served by underground water and sewer, which enter along the southern
portion of the site building from Worcester Road. The property is also serviced by gas and
overhead electric and telephone service entering from the southeast corner of the site building.

2.0 POTENTIAL RECEPTORS AND EXPOSURE PATHWAY
2.1 Potential Sensitive Receptors
Kleinfelder personnel reviewed available data to determine potential receptors including but not
limited to humans, subsurface utility conduits, potable water supplies, surface water bodies, natural
resource areas, schools and institutions, and buildings in the vicinity of the subject property. Please
refer to the MassGIS Priority Resource Map included as Figure 3.
2.2 Surface Water and Wetlands
No surface water or wetlands are located within 500 feet of the site. The closest surface water
body to the site is Jennings Pond located approximately 570 feet southeast of the site. Reed Pond
is located approximately 1,680 feet northeast of the site and Mud Pond is located approximately
2,370 feet to the west. DEP wetlands are located to the northeast (approximately 915 feet), to the
west (approximately 1,050 feet) and to the southeast (approximately 1,115 feet).
2.3 Potable Water Supplies
The site is in an area designated as a medium yield potentially productive aquifer and is mapped
by the Town of Natick as a “groundwater recharge area” (refer to Figure 3). A Zone II area is
located approximately 525 feet north-northwest of the site. Eight municipal drinking water wells
are located within 4,921 feet of the site to the southeast and northwest, with the closest located
approximately 3,188 feet downgradient (southeast). One private well is reportedly located 885 feet
to the southwest of the site and used in a car wash operation.
2.4 Schools and Institutions
No schools or institutions were identified within 500 feet of the subject site. The closest school or
institution is the Crossroads School for Children, located approximately 0.82 miles north-northwest
of the site.
2.5 Other Potential Sensitive Receptors
Based on information from the Massachusetts GIS database, there are no known Areas of Critical
Environmental Concern or designated State, Federal, Municipal, or Private Open Space or
Recreational Facility areas within a 500 foot radius of the subject site. The MassGIS priority resource
map is included as Figure 3.

3.0 IMPLEMENTATION OF COMPREHENSIVE RESPONSE ACTIONS
Since the submission the Phase IV Status Report on April 13, 2016, Kleinfelder conducted the
following field work to implement the remedial alternative selected in the Phase IV RIP (enhanced
bioremediation using BOS 200® followed by MNA). Field work included baseline groundwater
monitoring, BOS 200® injections, and periodic post-injection groundwater monitoring.
3.1 BOS 200® Injections
From June 21 through 26, 2016, Kleinfelder personnel were onsite to oversee Geosearch
Environmental Contractors Inc. (Geosearch) and AST Environmental, Inc. (AST) conduct BOS
200® injections at 59 locations. BOS 200® consists of carbon, calcium sulfate, nitrate, phosphate,
and ammonia. The BOS 200® product traps contaminants via carbon adsorption and subsequently
facilitates biological degradation of the petroleum constituents present in the dissolved phase and
sorbed to saturated zone soils. Please refer to Figure 4 for the approximate injection locations.
AST Environmental prepared a slurry consisting of approximately 14% (by weight) BOS 200®, and
bacteria concentrate. In total, approximately 6,305 pounds of BOS 200®, 13 gallons of bacteria
concentrate, and 8,125 gallons of water were injected. The remedial additive was injected at a
depth interval of approximately 18 to 28 feet below ground surface (bgs) using a Geoprobe®. To
ensure distribution of the remedial additive at the targeted depths, the slurry was injected in two-
foot lifts of 15 to 25 pounds of BOS 200® per lift. Due to the nature of the lithology and subsurface
conditions, slight variations of injection interval and injection amount were made based on field
observations. Down-well groundwater monitoring was periodically performed on select wells
during injection activities. Refer to Table 1 for injection related monitoring data.
3.2 Groundwater Monitoring Activity
Groundwater monitoring was performed before, during, and after injections to evaluate the effects
of the remedial additives on site groundwater. Water quality parameters dissolved oxygen (DO),
oxidation reduction potential (ORP), conductivity, pH, and temperature were monitored using a
YSI 600 water quality meter. The YSI sonde was deployed approximately one foot below the water
table and allowed to stabilize for approximately 60 seconds before taking readings. Following field
water quality monitoring, a minimum of three standing well volumes of groundwater were purged
from each monitoring well. Groundwater samples were submitted for laboratory analysis of volatile
organic compounds (VOCs) via Environmental Protection Agency (EPA) 8260 methodology,
volatile petroleum hydrocarbons (VPH) via MassDEP approved methodology, sulfate via American
Society for Testing Materials (ASTM) 516-90, nitrite, and nitrate via EPA 353.2 methodology.
135659/FRM16R48263 Page 7 of 18 October 18, 2016
During BOS 200® injections, groundwater monitoring was conducted at monitoring wells A-4, OW-
3, OW-7, and OW-9R.
3.2.1 Baseline Conditions
Prior to the BOS 200® injections, on May 27, 2016, groundwater monitoring was conducted at
monitoring wells A-1, A-4, OW-3, OW-7, OW-8, OW-9R, and OW-10 to document the pre-injection
conditions at the site and establish a baseline for comparison to future data. Refer to Tables 2
and 3 for groundwater gauging and analytical results, and Table 4 for injection-related monitoring
results. The VPH distributions are displayed on Figures 5, 6, 7, and 8 respectively. Complete
laboratory reports are included as Appendix A. The following pre-injection baseline measurements
were recorded:
DO concentrations ranged from 2.44 milligrams per liter (mg/L) at monitoring well OW-3 to 6.32 mg/L at monitoring well OW-8.
Conductivity measurements ranged from 303 microSiemens per centimeter (μS/cm) at well A-1 to 1,601 μS/cm at well OW-8.
Sulfate ranged from 14.8 mg/L in well OW-8 to 55.7 mg/L at monitoring well A-4.
Nitrogen (sum of nitrate and nitrite) ranged from 0.84 mg/L in well OW-7 to 7.4 mg/L in well OW-8.
Total VPH ranged from below laboratory reporting limits at monitoring wells OW-8 and OW-10 to 15,275 µg/L at well OW-9R.
3.2.2 Post-injection Conditions
On June 25, 2016, groundwater samples were collected from downgradient monitoring wells OW-
8, OW-9R, and OW-10 and submitted to SGS for analysis of VPH. Total VPH concentrations
ranged from below laboratory detection limits in monitoring wells OW-8 and OW-10 to 21,252 µg/L
in monitoring well OW-9R.
On July 6, 2016 groundwater samples were collected from monitoring wells A-1, A-4, OW-3, and
OW-7 and submitted to SGS for analysis of VPH, VOCs, nitrate, nitrite, and sulfate. Monitoring
wells OW-5, OW-6, OW-8, OW-9R, and OW-10 were located under bituminous asphalt applied
following re-paving of Massachusetts State Route 9 and were inaccessible. Total VPH
concentrations ranged from 1,128 µg/L in monitoring well A-1 to 4,690 µg/L in monitoring well OW-
3.
135659/FRM16R48263 Page 8 of 18 October 18, 2016
On August 18, 2016 Kleinfelder supervised Geosearch access and repair groundwater monitoring
wells OW-5, OW-6, OW-8, OW-9R, and OW-10 which were paved over in June 2016. Geosearch
removed 3 inches of bituminous asphalt to access each monitoring well. The monitoring well road-
boxes were observed to be present and intact upon inspection. Geosearch replaced each
monitoring well road-box with an 8-inch traffic-rated road-box and finished each road-box
installation with hot bituminous asphalt to surrounding grade. Following monitoring well repairs,
each monitoring well was gauged for depth to water and depth to bottom using an interface probe.
Each monitoring well was re-developed using a Proactive branded Water Spout 2 Complete®
submersible pump to purge and remove ten standing well volumes.
On September 2, 2016 Kleinfelder personnel conducted post-injection groundwater monitoring and
sampling at monitoring wells A-1, A-4, OW-3, OW-8, OW-9R, and OW-10. Depth to water was
measured using an interface probe at each monitoring well. Depth to water measurements ranged
from 19.89 feet bgs (A-1) to 21.90 feet bgs (A-4). It should be noted that these were the lowest
recorded water levels in several years. Non-aqueous phase liquid (NAPL) was measured at 0.02
feet thickness in monitoring well OW-7. The presence of NAPL in well OW-7 has been previously
reported to MassDEP and is not related to a new release but rather a result of the recent drought
conditions. Groundwater was not sampled from monitoring well OW-7 during this monitoring event.
Groundwater samples were submitted to SGS for analysis of VPH, VOCs, nitrate, nitrite, and
sulfate. Total VPH concentrations ranged from below laboratory detection limits in monitoring wells
OW-8 and OW-10 to 21,369 µg/L in monitoring well OW-9R.
Please refer to Tables 4 for post-injection-related monitoring results and Table 2 for a summary of
groundwater gauging and analytical results. The distribution of VPH concentrations detected
during baseline sampling, and subsequent post-injection monitoring are displayed on Figures 5, 6,
7, and 8. Complete laboratory results are included in Appendix A. These monitoring data were
evaluated relative to the baseline monitoring data collected in May 2016 and the data collected
during the injections.
Increases in conductivity, which is an indicator of total dissolved solids, in wells A-4, OW-3, and
OW-7, increases in sulfate in wells A-4, OW-3, OW-7, and OW-10, and decreases in total VPH in
wells OW-3 and OW-7 indicate that the BOS 200® mixture was effectively delivered to the target
area.
In accordance with 310 CMR 40.1403(10), property owners have been provided the results of the
May, June, July, and September 2016 monitoring events (Appendix B).
135659/FRM16R48263 Page 9 of 18 October 18, 2016
4.0 PHASE IV COMPLETION STATEMENT
Kleinfelder, on behalf of EMES, has completed Phase IV Comprehensive Response Actions in
accordance with 310 CMR 40.0870 for the disposal site located at 99 Worcester Road in Natick,
Massachusetts. Based on the information obtained during the implementation of the
Comprehensive Remedial Action, as presented herein, the performance standards as described
in 310 CMR 40.0872 are viewed to have been met in accordance with 310 CMR 40.0879(2).
During the course of the Phase IV activities discussed herein, a total of 6,305 pounds of BOS 200®
was injected into the subsurface at 59 injection points. Field monitoring conducted during injection
activities identified variations in aquifer parameters. While additional monitoring will be necessary
to further evaluate the effects of BOS 200®, it is appears that this remedial alternative,
supplemented with monitored natural attenuation (MNA), will be an effective means of achieving a
permanent solution for this site.
Following the submittal of this Phase IV Completion Statement and ROS Opinion, ROS activities
will include periodic monitoring events as well as additional response actions deemed necessary
based on monitoring results. Additional activities may include additional BOS 200® injection
events. Subsequently, data will be evaluated to assess progress towards a condition of No
Significant Risk and a Permanent Solution.
135659/FRM16R48263 Page 10 of 18 October 18, 2016
5.0 SUBSTANTIAL HAZARD EVALUATION
To fulfill the requirements of a ROS Opinion, a SHE was performed for the disposal site associated
with RTN 3-0715. Substantial Hazard, as discussed in 310 CMR 40.0956, refers to a condition that
would pose a significant risk of harm to human health or the environment over an exposure period
from the time of notification to the present time plus five years. Under current site uses, potential
exposure to employees of the Jiffy Lube® service station, neighboring residents, utility workers,
and ecological receptors was qualitatively evaluated. The residual petroleum constituents
detected in soil and groundwater samples collected from the site are related to release(s) in the
vicinity of the gasoline UST systems on the subject property. This evaluation was performed to
assess the potential exposure pathways and hazards associated with the residual concentrations
of petroleum constituents in site soil and groundwater.
5.1 Applicability of Soil and Groundwater Standards
For the purpose of evaluating the exposure potential to soil, the MCP classifies soil in three distinct
categories: S-1, S-2, and S-3. Category S-1 soils are associated with the highest potential for
exposure while Category S-3 soils have the lowest potential for exposure. The divisions amongst
the soil categories are dependent upon the frequency and intensity of site use by both children
and adults, and the accessibility of the site soil. The table presented in 310 CMR 40.0933(9)
contains a matrix summarizing the criteria used to categorize soil.
The frequency of exposure for employees that work on-site is considered high and the intensity of
soil exposure is low because employees are present at the site on a periodic basis but are not
involved in activities that disturb the soil. Visitors and trespassers (including children) at the site
are assumed to have a low frequency and intensity of exposure. Construction or utility workers
that may be involved with redevelopment or utility repair work on the site are considered to have
a low frequency and high intensity of soil exposure because they are present on the site for a short
period of time (i.e., a time period that is typically less than 6 months) and are involved in activities
that may disturb the soil. The majority of the site is paved with asphalt, therefore Soil Category S-
3 applies to soil in the upper 15 feet of the paved areas and Soil Category S-2 applies to soil in the
upper three feet of the paved areas. Soil in the landscaped portions of the site at depths less than
three feet are classified as S-1. Should future ground-intrusive activities be conducted at this
property, the frequency of use would then be classified as low as activities of this nature are not
anticipated to be conducted on a continuous basis. In the event that future ground-intrusive
activities do take place at this property, only adults are anticipated to be present with respect to
petroleum-affected soil deemed “accessible”.
135659/FRM16R48263 Page 11 of 18 October 18, 2016
The GW-1 standards were derived to be protective of use of groundwater as drinking water. The
site is located in area designated as potentially productive medium aquifer. Therefore all site wells
are classified as GW-1. Eight municipal drinking water wells are located within 4,921 feet of the
site to the southeast and northwest. The closest municipal drinking water well is located
approximately 3,188 feet downgradient (southeast). One private well is reportedly located 885 feet
to the southwest of the site and used in a car wash operation. There are no known private drinking
water wells within 500 feet of the site.
The GW-2 standards were derived to be protective of volatile migration through the vadose zone
and indoor air vapor intrusion. Depth to groundwater is calculated to average greater than 15 feet
bgs, therefore, groundwater category GW-2 does not apply to site wells.
The Method 1 Risk Characterization GW-3 standards were derived to be protective of aquatic
organisms in surface water affected by site groundwater constituent migration. The nearest
surface water body is Jennings Pond located approximately 570 feet southeast of the site. All site
wells are classified as GW-3.
5.2 Soil Conditions
Soil analytical data for the site includes six samples collected from three soil borings by Kleinfelder
in August 2015. Soil samples were collected from soil borings SB-3, SB-1, and SB-2 located
upgradient, within, and downgradient of the historical source area respectively. Soil samples
ranged in depth from 18 to 26 feet bgs, and were analyzed for volatile petroleum hydrocarbons
(VPH) (Appendix C).
5.3 Groundwater Conditions
Groundwater samples have been collected at this site since 1989 from site-related monitoring
wells. Recent groundwater gauging and analytical data are presented in Table 2. Historical
groundwater analytical data is included as Appendix C. Groundwater samples have been
analyzed for VPH and target analytes via MassDEP-approved methodology. The delineation of
petroleum-affected groundwater has historically been defined by monitoring wells that have
exhibited low constituent concentrations and/or in which constituents were infrequently detected.
The historical limits of affected groundwater were horizontally and vertically delineated at this site
as within the area of monitoring well locations OW-11 to the north, A-1 to the east, OW-10 to the
southeast, OW-8 to the southwest, and OW-1 to the west. Groundwater monitoring data collected
135659/FRM16R48263 Page 12 of 18 October 18, 2016
from monitoring well OW-9R indicate that petroleum-affected groundwater is likely to extend under
a portion of state highway Route 9 to the south of the site.
The horizontal extent of petroleum-affected groundwater has been established by elevated
concentrations of VPH detected historically in samples collected from monitoring wells A-4, OW-
3, and OW-7. Over the recent two-year period of groundwater monitoring, petroleum constituents
including ethylbenzene, total xylenes, naphthalene, C5-C8 aliphatics, C9-C12 aliphatics, and C9-C10
aromatics have been detected above MCP Method 1 GW-1 standards in groundwater collected
from monitoring wells A-1, A-4, OW-3, OW-7, and OW-9R. The highest concentration of
constituents was detected in monitoring wells located immediately west, and south of the former
gasoline tank field.
The direction of groundwater in the overburden aquifer has been calculated to be to the south/
southwest. As shown in Table 2, groundwater analytical data collected since 1989 indicate that
overall petroleum mass and the area of affected groundwater are decreasing over time. The
historical maximum extent of affected area has been adequately delineated and, based on historical
sampling data, has not, nor is likely to, affect the above mentioned receptors.
Soil analytical results following the recent August 2015 soil boring investigation indicate no
exceedances of applicable MCP Method 1 Soil Standards with the exception of naphthalene, and
C9-C10 aromatic hydrocarbons in a single location within the former gasoline tank field area. Under
current conditions, petroleum-affected soil is at a depth of approximately 18 feet bgs, under the
paved surface of the site.
Therefore, there are no current exposures to affected soil at this site for neighboring residents, site
employees, customers, future construction workers, and utility workers. Therefore, exposure to
soil via these pathways is incomplete. Based on this analysis, no substantial hazards with regard
to soil exist at the site.
135659/FRM16R48263 Page 13 of 18 October 18, 2016
5.4.2 Groundwater Ingestion
Although the site is located within a potential drinking water source area (Potentially Productive
Medium Yield Aquifer), groundwater sample analytical results appear to have defined the full
horizontal and vertical extent of dissolved-phase petroleum affect at this site. As shown in Table 2,
groundwater analytical data collected since 1989 indicate that overall petroleum mass and the area
of affected groundwater are decreasing over time. The historical maximum extent of affected area
has been adequately delineated and, based on historical sampling data, has not, nor is likely to,
affect the above mentioned receptors. On this basis, the groundwater ingestion pathway is
considered to be incomplete and as such, does not represent a substantial hazard to groundwater
off-site.
5.4.3 Volatilization
There are residential properties with basements within 300 feet of the site. The depth to groundwater
at the site is approximately 16-22 feet bgs. Groundwater averages at greater than 15 feet bgs, and
volatile constituents at concentrations greater than Method 1 GW-2 groundwater standards have not
been detected in monitoring wells within 30 feet of a building since August 2010 (OW-7 C9-C10
aromatics). Concentrations of soil vapors measured most recently in August 2015 at soil vapor point
VP-1 were below applicable threshold levels (Table 5). Therefore, volatilization of constituents into
indoor air of the on-site building is not considered a potentially complete exposure pathway.
5.4.4 Ecological Risk Evaluation
As specified in 310 CMR 40.0956(2), the focus of an Ecological Substantial Hazard Evaluation shall
be on any environmental resource areas, such as wetlands, aquatic terrestrial habitats, and fisheries
that exist at a site. There are no mapped wetlands, aquatic habitats or fisheries that exist on the
site. The closest surface water body to the site is Jennings Pond located approximately 570 feet
southeast of the site. Reed Pond is located approximately 1,680 feet northeast of the site and
Mud Pond is located approximately 2,378 feet to the west. DEP wetlands are located to the
northeast (approximately 915 feet), to the west (approximately 1,050 feet) and to the southeast
(approximately 1,115 feet).
There have been no recent concentrations of petroleum constituents detected in the most down
gradient wells above Method 1 GW-3 groundwater risk characterization standards, with the
exception of total xylene concentrations detected in monitoring well OW-9R. As shown in Table 2
and Appendix C, groundwater analytical results from monitoring wells located between monitoring
well OW-9R and the above mentioned receptors (A-1, A-7, OW-1, OW-8, OW-10 and OW-11) have
135659/FRM16R48263 Page 14 of 18 October 18, 2016
demonstrated concentrations of total xylenes and other target constituents below the applicable
Method 1 GW-3 groundwater standards. As such, it is the opinion of Kleinfelder that there is not a
complete pathway from site groundwater to surrounding surface water receptors. On this basis,
current site groundwater conditions do not pose a substantial hazard to ecological receptors.
5.4.5 Utility Workers
Under current conditions, utility workers engaged in emergency utility repair work may be exposed
to constituents of concern in soil and groundwater via dermal contact, incidental ingestion, and
inhalation of ambient air. Site soil has been demonstrated to pose no significant risk to receptors.
The concentrations of VPH in site groundwater do not meet the conditions provided by MassDEP
for when a quantitative evaluation of risk to utility workers is required. These include exposures
associated with acute, non-cancer effects, inhalation of vapors from NAPL, or potential explosive
vapors. Therefore, petroleum-affected groundwater does not pose a substantial hazard to utility
workers under current site conditions.
5.5 Findings of Substantial Hazard Evaluation
In conclusion, a qualitative evaluation of hazards posed by site soil and groundwater conditions
under currently foreseeable site uses and activities found no complete exposure pathways that
would pose a significant risk to human health or ecological receptors. Thus, in accordance with
310 CMR 40.0956, a condition of No Substantial Hazard currently exists to human health or the
environment at the site.
135659/FRM16R48263 Page 15 of 18 October 18, 2016
6.0 REMEDY OPERATION STATUS OPINION
Phase IV activities have been completed pursuant to the provisions set forth in 310 CMR 40.0800
for Comprehensive Response Actions. The continued operation, maintenance and monitoring of
the Comprehensive Remedial Action will be conducted at this site under the ROS provisions set
forth in 310 CMR 40.0890. Accordingly, the objective of this section is to demonstrate that the
criteria set forth in 310 CMR 40.0893 for ROS have been achieved at this site based on the
following criteria:
the remedial program presented in the Phase III-IV dated October 16, 2015 has been adequately designed in accordance with 310 CMR 40.0870 to achieve a Permanent Solution;
the remedial program will be operated and maintained in accordance with the requirements of 310 CMR 40.0890;
the source of oil and/or hazard material (OHM) associated with this site has been eliminated and/or controlled pursuant to 310 CMR 40.1003(5);
current site conditions do not constitute a substantial hazard at this site; and
information and data on operation and maintenance and/or monitoring will be documented and submitted to the MassDEP every six months in a reports as described in 310 CMR 40.0892.
Based on the information presented, it is the opinion of Kleinfelder that the remedial program has
been conducted in accordance with the requirements of 310 CMR 40.0870, that the source of OHM
has been eliminated or controlled in accordance with 310 CMR 40.1003(5), and that substantial
hazards have been eliminated. Kleinfelder will continue to review all provided information and the
current site conditions and to re-evaluate their opinions as new information becomes available.
6.1 Future Remedial Actions
Following the submission of this ROS Opinion, groundwater monitoring activities will continue on
an approximate quarterly to semi-annually basis. Select site wells will be gauged and sampled for
laboratory analysis of VPH constituents. NAPL conditions will continue to be monitored at
monitoring well OW-7. If areas of the site do not adequately respond to the initial BOS 200®
injections and data indicate that MNA will not be suitable to achieve a condition of no significant
risk in the foreseeable future then, additional remedial injections may be conducted under ROS.
135659/FRM16R48263 Page 16 of 18 October 18, 2016
The results of these monitoring activities will be tabulated and submitted to the MassDEP twice
per year in ROS Reports. Based on an ongoing evaluation of the data collected, the scope and
frequency of monitoring may be modified at the direction of the LSP. Any such modifications will
be supported and documented in ROS reports.
6.2 Reporting
Subsequent to the submittal of this ROS Opinion, ROS Reports will be submitted, at minimum,
every six months from the submittal of this report until such time that a Permanent Solution may
be achieved through the demonstration of a condition of “no significant risk” in accordance with the
requirements of 310 CMR 40.1000. Each report will be completed in accordance with 310 CMR
40.0893.
6.3 Future Course of Action The following is a tentative timeline for upcoming response actions:
Groundwater Monitoring Events – December 2016 and March 2017
