Executive Summary

The Army National Guard (ARNG) is performing Preliminary Assessments (PAs) and Site

Inspections (SIs) for Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA)

Impacted Sites at ARNG Facilities Nationwide. A PA for per- and polyfluoroalkyl substances

(PFAS)-containing materials was completed for Camp Edwards, located on Joint Base Cape Cod

(JBCC), Massachusetts. The goal of the PA is to ensure that any potential PFAS release areas

and exposure pathways to receptors are appropriately addressed.

The Joint Base Cape Cod (JBCC) is a 22,000-acre military training facility home to three

Department of Defense (DoD) Agencies and one Homeland Security Agency: Cape Cod Air Force

Station (United States [U.S.] Air Force), Otis Air National Guard Base (Air National Guard), Camp

Edwards (Army National Guard) and the U.S. Coast Guard Air Station Cape Cod, respectfully.

In 1989, the installation was listed on the National Priority List (NPL) as a superfund site. There

are two separate environmental cleanup programs still active at JBCC. The U.S. Air Force Civil

Engineer Center (AFCEC) manages the Installation Restoration Program (IRP) for both the Army

and the Air Force, using environmental restoration funds from both Army and Air Force accounts.

In 1996, the Army National Guard Bureau (NGB) established the Impact Area Groundwater Study

Program (IAGWSP) to examine the impacts of military training and defense contractor testing

activities at the installation on the environment, specifically the groundwater. The IRP cleanup is

regulated under the Comprehensive Environmental Response, Compensation and Liability Act of

1980 (CERCLA) and the IAGWSP cleanup is regulated under the Safe Drinking Water Act

(SDWA). The IAGWSP and AFCEC closely coordinate all activities to ensure, to the extent

possible, the programs take a common approach on technical issues, management processes

and interaction with the regulators, the public and other stakeholders.

Any potential future actions related to sites identified under this PA will be addressed by these

established cleanup programs at JBCC.

Potential release areas identified on JBCC and the contiguous area surrounding Camp Edwards

are described in this PA as adjacent sources along with other adjacent sources outside of the

JBCC facility.

The performance of this PA included the following tasks:

· Reviewed available administrative record documents and public records to obtain information

relevant to potential PFAS releases, such as: drinking water well locations, historical aerial

photographs, and environmental compliance actions in the area surrounding the facility;

· AECOM conducted a site visit on 13 September 2018 and completed visual site inspections

at locations where PFAS-containing materials were suspected of being stored, used, or

disposed; 

· Collaborative interviews have been conducted with current Camp Edwards personnel for the

impact area groundwater study program, AFCEC personnel, and ARNG environmental

managers and operations staff;

· Identified Area(s) of Interest (AOIs) and developed a preliminary conceptual site model (CSM)

to summarize potential source-pathway-receptor linkages of potential PFAS in soil,

groundwater, surface water, and sediment for each AOI.

Six AOIs related to a PFAS release were identified at Camp Edwards during the PA. The AOIs

are shown on Figure ES-1 and Figure ES-2 and are described below:

The AFCEC IRP is performing ongoing PFAS-related activities at AOI 1 through AOI 5; future 

actions at these AOIs will continue to be managed by the AFCEC IRP. Any future investigations

related to PFAS at AOI 6 will be managed by the IAGWSP.

Based on documented and potential PFAS releases at these AOIs, there is potential for exposure

to PFAS contamination in media at or near the facility. Actual and potential off-facility aqueous film

forming foam (AFFF) releases exist in the area, which have a potential effect on Camp Edwards.

The preliminary CSM for Camp Edwards’s AOIs is shown on Figure ES-3.

1. Introduction

1.1 Authority and Purpose

The Army National Guard (ARNG) G9 is the lead agency in performing Preliminary Assessments

(PAs) and Site Inspections (SIs) for Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic

acid (PFOA) at Impacted Sites at ARNG Facilities Nationwide. This work is supported by the

United States (U.S.) Army Corps of Engineers (USACE) Baltimore District and their contractor

AECOM Technical Services, Inc. (AECOM) under Contract Number W912DR-12-D-0014, Task

Order W912DR17F0192, issued 11 August 2017.

The ARNG is assessing potential effects on human health related to processes at facilities that

used per- and poly-fluoroalkyl substances (PFAS), primarily in the form of aqueous film forming

foam (AFFF) released as part of firefighting activities, although other PFAS sources are possible.

In addition, the ARNG is assessing businesses or operations adjacent to the ARNG facility (not

under the control of ARNG) that could potentially be responsible for a PFAS release.

PFAS are classified as emerging environmental contaminants that are garnering increasing

regulatory interest due to their potential risks to human health and the environment. PFAS

formulations contain highly diverse mixtures of compounds. Thus, the fate of PFAS in the

environment varies. The regulatory framework at both federal and state levels continues to evolve.

The U.S. Environmental Protection Agency (USEPA) issued Lifetime Drinking Water Health

Advisories (HAs) for PFOA and PFOS in May 2016, but there are currently no promulgated

national standards regulating PFAS in drinking water. The HA is 0.07 micrograms per liter (μg/L)

for PFOS and PFOA, individually or combined.

This report presents findings of a PA for PFAS-containing materials at Camp Edwards, located on

Joint Base Cape Cod (JBCC), Massachusetts, in accordance with the Comprehensive

Environmental Response, Compensation, and Liability Act (CERCLA), as amended, the National

Oil and Hazardous Substances Pollution Contingency Plan (40 Code of Federal Regulations

[CFR] Part 300), and Army requirements and guidance.

This PA documents the known release areas as well as other locations where PFAS may have

been released into the environment at Camp Edwards. The term PFAS will be used throughout

this report to encompass all PFAS chemicals being evaluated, including PFOA and PFOS, which

are key components of AFFF.

1.2 Preliminary Assessment Methods

The performance of this PA included the following tasks:

· Reviewed available administrative record documents and public records to obtain information

relevant to potential PFAS releases, such as: drinking water well locations, historical aerial

photographs, and environmental compliance actions in the area surrounding the facility;

· AECOM conducted a site visit on 13 September 2018 and completed visual site inspections

at locations where PFAS-containing materials were suspected of being stored, used, or

disposed; 

· Collaborative interviews have been conducted with current Camp Edwards personnel for the

impact area groundwater study program, U.S. Air Force Civil Engineer Center (AFCEC)

personnel, and ARNG environmental managers and operations staff;

1.4 Facility Location and Description

Camp Edwards is located on JBCC (Figure 1-1) in Barnstable County, Massachusetts,

approximately 60 miles south of Boston. The facility is located in the upper portion of Cape Cod,

with Cape Cod Bay to the north, Nantucket Sound to the south, and Buzzards Bay to the west.

The Cape Cod Canal connects Cape Cod Bay and Buzzards Bay to the north of JBCC. The

northeastern corner of JBCC is adjacent to the Shawme-Crowell State Forest, and the south and

southwest portions of JBCC are bounded by the Frances Crane Wildlife Management Area, the

Ashumet Pond Sanctuary, and the Johns Pond Park Conservation Area.

JBCC occupies approximately 22,000 acres (34 square miles) within the towns of Bourne,

Falmouth, Mashpee, and Sandwich, and is divided into two distinct areas: the Training Range and

Impact Area and the Cantonment Area. Camp Edwards occupies 14,433 acres within the Training

Range and Impact Area, which consists of 22 maneuver training areas, Chemical Spill 10 (Former

BOMARC Site), small arms ranges, and the impact area and its buffers. The remainder of the

Training Range and Impact Area is occupied by the U.S. Coast Guard (USCG) Transmitter Site,

the U.S. Air Force (USAF) Precision Acquisition Vehicle Entry – Phased Array Warning System

(PAVE-PAWS) Radar Site, former Landfill #1 (LF-1), Barnstable County Correctional Facility, two

former demolition areas, the former Otis Fish and Game Club, the Upper Cape Regional Water
PFAS Preliminary Assessment Report

Camp Edwards, Massachusetts

AECOM 8

Cooperative, a wastewater infiltration bed, and various utility easements (Massachusetts ARNG

[MAARNG], 2009).

Camp Edwards occupies 697 acres of the Cantonment Area, making up 12 percent of the total

Cantonment Area. The Camp Edwards facilities within the Cantonment Area include ARNG

Training Support Facilities, ARNG Aviation (helicopter) Facilities, the Regional Training Institute,

Bachelor Officer’s Quarters, Billeting (housing assignment office), and grassland management

areas. The remainder of the Cantonment Area is occupied by Otis Air National Guard (ANG) Base,

USCG Air Station Cape Cod, Veteran’s Affairs National Cemetery, Bourne School System, a

portion of the Crane Wildlife Management Area, and the remainder of the grassland management

area (MAARNG, 2009).

1.5 Facility Environmental Setting

Camp Edwards is located in the northwestern portion of Cape Cod, between Buzzards Bay and

Cape Cod Bay. The elevation of the facility is approximately 125 feet (ft) above mean sea level

(amsl). The terrain is gently sloping to the south, with hummocky topography characterized by

rolling hills and deep kettle holes with slopes ranging from 0 to 15 percent. The highest point on

Cape Cod, Pine Hill (318 ft amsl), is located in the western part of Camp Edwards (AFCEC, 2017).

1.5.1 Geology

JBCC is located in the Seaboard Lowlands section of the New England Physiographic Province

in the Appalachian Highlands physiographic region. The Seaboard Lowlands represent the areas

that were submerged by the ocean and large proglacial lakes during the Late Wisconsinan glacial

retreat (Stone and Borns, 1986).

Camp Edwards is situated on the Wisconsinan-age glacial deposits of Cape Cod, as shown on

Figure 1-2. The northern and western portions of Camp Edwards are occupied by the Sandwich

and Buzzards Bay moraines. These two glaciotectonic moraines are composed of ablation till,

with unsorted material ranging from boulders to clay overlying reworked basal till; these moraines

are approximately 100 ft thick. The remainder of Camp Edwards is located on the Mashpee pitted

outwash plain, consisting of sandy sediments that were deposited in a delta that prograded to the

southeast (Fitts, 2013). Foreset beds are composed of coarser sand, gravel, and cobble

sediments, whereas bottomset beds are composed of fine sand and silt. The thickness of the

Mashpee pitted outwash plain ranges from approximately 175 ft in the northwest to approximately

250 ft near Nantucket Sound in the south. The moraine and outwash deposits overlie fine-grained

proglacial lake and ground moraine deposits composed of dense silt and clay (Fitts, 2013). The

outwash plain also contains many glacial collapse structures formed from the melting of buried

blocks of remnant glacial ice that form topographic depressions that commonly contain kettle-hole

ponds (Walter et al., 2002).

1.5.2 Hydrogeology

Camp Edwards is located over the Sagamore Lens of the Upper Cape Cod Aquifer, which has

been designated a sole source aquifer by the USEPA (MAARNG, 2009). This aquifer is

unconfined, with areal recharge from precipitation as the sole source of water to the aquifer. The

lateral boundaries of the aquifer are saltwater from Buzzards Bay, Cape Cod Bay, and Nantucket

Sound, and the vertical boundary is formed by the impermeable bedrock below the aquifer.

Groundwater flow is radial from a water-table mound located in the eastern portion of Camp

Edwards, to the north of Snake Pond, where the maximum hydraulic-head altitude is

approximately 70 ft amsl (Walter et al., 2002). Depths to the water table are typically 0-100 ft

below ground surface (bgs). Groundwater at Camp Edwards generally flows to the south in the
PFAS Preliminary Assessment Report

Camp Edwards, Massachusetts

AECOM 9

southern portion, to the west in the western portion, and to the north in the northern portion

(Figure 1-2).

Hydraulic conductivities in the aquifer range from 10 ft per day (ft/day) to 290 ft/day, with hydraulic

conductivity generally decreasing with depth. The horizontal-to-vertical hydraulic conductivity

ratios range from 3:1 in the outwash deposits up to 100:1 in the lacustrine deposits (Walter et al.,

2002). The effective porosities of the aquifer generally range from 0.32 to 0.42.

Surface water bodies are generally hydraulically connected to groundwater (groundwater flowthrough ponds), with groundwater flowing into the pond on the upgradient side and out of the

pond on the downgradient side. As a result, groundwater gradients are usually highest near the

shore of the pond (Walter et al., 2002).

Using additional resources, such as state and local Geographic Information System (GIS)

databases, wells were researched to a 4-mile radius of the facility. Multiple community and noncommunity drinking water supply wells are located on and within a mile of the property and

downgradient from the water table mound observed in the eastern portion of Camp Edwards

(Figure 1-2). Community wells are defined as wells associated with public water systems that

supply potable water to the same residential population year-round. Non-community wells are

associated with public water systems designed to supply drinking water to locations that have

their own water systems and that either support at least 25 people at least 6 months per year

(non-transient; e.g., schools, factories, office buildings, hospitals), or that are not designed to

support the same people for long periods of time (transient; e.g., service stations, campgrounds)

(USEPA, 2017).

In 2014, drinking water samples were collected from eight wells on base and within one mile of

Camp Edwards as part of the USEPA Unregulated Contaminant Monitoring Rule 3 (UCMR3)

program. The purpose of the UCMR3 is to collect data for contaminants that are suspected to be

present in drinking water and do not have health-based standards set under the Safe Drinking

Water Act (SDWA). Collected drinking water samples were analyzed for various PFAS, including

PFOS, PFOA, perfluorononanoic acid (PFNA), perfluorobutanesulfonic acid (PFBS),

perfluoroheptanoic acid (PFHpA), and perfluorohexanesulfonic acid (PFHxS). None of the

analytes were detected in the eight sampled wells (USEPA, 2012). PFAS analyses performed in

2014 had method detection limits that were higher than currently achievable. Thus, it is possible

that low concentrations of PFAS were not detected during the UCMR3 but might be detected if

analyzed today.

1.5.3 Hydrology

No surface water currently enters Camp Edwards. There are no large lakes, rivers, or streams on

the JBCC property (MAARNG, 2009). Numerous small (less than 1 acre) wetlands and ponds are

located on Camp Edwards. The wetlands are characterized as palustrine, emergent wetlands,

bogs, and swamps. Some of the ponds and wetlands are groundwater flow-through kettle holes

with little surface drainage, whereas others are perched water features on localized, relatively

impermeable deposits. Due to the highly permeable nature of the soils at Camp Edwards, surface

water flow is negligible. Overland flow is primarily controlled by a stormwater drainage system.

There are numerous surface water features near Camp Edwards, as shown on Figure 1-3. The

Shawme Lakes are located near the northeast boundary of Camp Edwards and are drained by

Mill Creek, which flows into salt marshes and discharges to Cape Cod Bay. To the east are Snake,

Peters, Wakeby, and Mashpee Ponds. Ashumet, Johns, and Moody Ponds, as wells as the

Quashnet River and Bog System, are located generally to the south of Camp Edwards. To the

west, several small ponds and rivers drain westward into Buzzards Bay. The Cape Cod Canal is

located on the northern boundary of Camp Edwards and connects Buzzards Bay to Cape Cod

Bay.

1.5.4 Climate

The climate at Camp Edwards is humid continental, with warm summers and cold, snowy winters.

The climate is influenced by proximity to the Atlantic Ocean, with generally cooler summers and

warmer winters than inland locations. The average temperature is 49.4 degrees Fahrenheit (°F),

with summer highs of 76.4 °F and winter lows of 23.9 °F (National Oceanic and Atmospheric

Administration [NOAA], 2018). Average annual precipitation is 45.16 inches.

1.5.5 Current and Future Land Use

Current Camp Edwards property is located in the Training Range and Impact Area. The Training

Range and Impact Area is used for military and public safety operations. Maneuvers, bivouac,

and range use are the most common activities in this location. The Cantonment Area is used

jointly by Otis ANG Base, USCG Air Station Cape Cod, Six-Missile Warning Squadron, and Camp

Edwards. The Cantonment Area is used primarily for military and public safety operations,

including administrative, operational, maintenance, and housing facilities. No changes in land use

are currently planned for Camp Edwards.

There are currently two environmental cleanup programs that are addressing PFAS at JBCC. In

1996, the Army National Guard Bureau (NGB) established the Impact Area Groundwater Study

Program (IAGWSP) to examine the impacts of military training and defense contractor testing

activities at the installation on the environment, specifically the groundwater. The AFCEC

Installation Restoration Program (IRP) has also conducted a PA and SI for PFAS at JBCC,

primarily in the Cantonment Area, and is currently conducting Remedial Investigations (RIs) and

an expanded SI for PFAS at JBCC. The AFCEC IRP has also conducted a time-critical removal

action treatment and is incidentally treating several groundwater plumes for PFAS as well as other

actions (AFCEC, 2018d).

2. Fire Training Areas

No FTAs were identified within the Camp Edwards facility during the PA through interviews or the

administrative record. Interview knowledge (1976 to 2019) and facility records dating to 1948

covered the entire duration of Camp Edwards’ operations during the period in which AFFF has

been in use. Army Aviation Support Facility (AASF) personnel currently train at an offsite location.

Fire training activities were conducted with AFFF on unlined fire pits on a few occasions in the

mid-1980s; however, no other information, including the location of these unlined fire pits, is 

available. Current fire training activities are conducted without the use of AFFF. Three former FTAs

were identified on JBCC adjacent to Camp Edwards property during the PA. Two of these FTAs

pre-dated the use of AFFF. The remaining FTA is addressed in Section 5.

AECOM 15

3. Non-Fire Training Areas

In addition to FTAs, the PA evaluated areas where PFAS-containing materials may have been

broadly used, stored, or disposed. This may include buildings with fire suppression systems, paint

booths, AFFF storage areas, and areas of compliance demonstrations. Information on these

features obtained during the PA are included in Appendices A and B. AFCEC has identified five

non-FTAs, and one additional non-FTA has been identified, all of which are described in the

following sections. The locations of the non-FTAs are shown on Figure 3-1, and the photographs

appear in Appendix C.

3.1 Hangar 2816

Hangar 2816 is located in the southeastern portion of Camp Edwards, on Richardson Road,

between Generals Boulevard and East Inner Road (Figure 3-1). The geographic coordinates are

41.659555°N; 70.535325°W. Hangar 2816, which houses rotary-winged aircraft, was constructed

in 1969 and is occupied by the MAARNG. Hangar 2816 contains a water-deluge sprinkler fire

suppression system and five 125/150-pound portable Amerex fire extinguisher units containing

Purple K, a dry-chemical fire suppression agent composed of potassium bicarbonate. The Hangar

2816 building includes floor drains which were previously connected to dry wells located on either

end of the building. The floor drains are now self-contained. Trench drains are located on the flight

line running parallel to the north side of Hangar 2816. There have not been any documented

releases of AFFF at this location.

Tri-MaxTM portable compressed air foam fire suppression system (CAFS) units were formerly used

outside Hangar 2816. The CAFS units were kept on the flight line and parking lot. Because they

were equipped with canvas covers, the CAFS units were not stored inside Hangar 2816.

According to interviewees, annual training was conducted with the CAFS units intermittently from

the late 1970s until approximately 2013. Only one CAFS unit was used for training during which

personnel discharged the CAFS unit in the parking lot immediately south of Hangar 2816. The

CAFS unit used a water and soap mixture during training exercises. The units were removed with

their contents intact an estimated 3 to 5 years ago.

AFCEC performed an SI at Hangar 2816 in 2017 (AFCEC, 2017). One direct-push groundwater

vertical profile boring was completed south of Hangar 2816. One groundwater sample collected

from 53.5 ft bgs exceeded the USEPA HA of 0.07 μg/L, with PFOS and PFOA concentrations of

0.053 μg/L and 0.046 μg/L, respectively (AFCEC, 2017). AFCEC is also performing an ongoing

expanded SI at Hangar 2816.

3.2 Building 2814

Building 2814 is located adjacent to Hangar 2816, on the southeastern portion of Camp Edwards

on Richardson Road, between Generals Boulevard and East Inner Road (Figure 3-1). The

geographic coordinates are 41.660028°N; 70.536491°W. Building 2814 is a former fire station

used by MAARNG and is currently occupied by MAARNG Echo Company. There have not been

any documented releases of AFFF at this location.

The MAARNG owned a class 530C fire truck that was stored at Building 2814 and carried AFFF.

The fire truck was parked in various locations on the property in a motor pool on the west and

north sides of Building 2814 between the late 1970s and early 1990s. Interviewees indicated that

the pump unit from the fire truck was removed and stored in the parking lot on the west side of

Building 2814. Additionally, approximately 20 5-gallon plastic drums of AFFF were stored in dirt

near Building 2814 during this time.
PFAS Preliminary Assessment Report

Camp Edwards, Massachusetts

AECOM 16

While historical records do not document AFFF releases at this AOI, an interviewee indicated that

the class 530C fire truck discharged AFFF foam to a grassy area on the north side of the Building

2814 motor pool in the late 1970s. A wash rack (WR) and an oil-water separator (OWS) were

installed at this location in 1989. Soil was removed from the location of the potential AFFF

discharge in order to build the WR/OWS pad. AFCEC is performing an ongoing investigation for

PFAS at Building 2814 as part of an expanded SI for Building 2816.

3.3 Landfill #1 (LF-1)

LF-1 occupies approximately 100 acres and is located in the southern portion of Camp Edwards,

bounded by Turpentine Road and Frank Perkins Road on the east and west, respectively, and

Herbert Road and Connery Avenue on the north and south, respectively (Figure 3-1). The

geographic coordinates are 41.673590°N; 70.554194°W. ARNG currently contributes 27 percent

of the funding towards the LF-1 remedial action objective. Unregulated disposal activities occurred

at LF-1 from approximately 1940 to 1984 in distinct areas known as the 1947 Cell, 1951 Cell,

1970 Cell, Post-1970 Cell, and Kettle Hole. Since 1984, regulated disposal activities have

occurred in the Post-1970 Cell under the Massachusetts Military Reservation (MMR) Hazardous

Waste Management Plan. Among the wastes believed to be included in LF-1 are municipal

sewage sludge and fire extinguisher fluids (AFCEC, 2018b). The landfill was capped in 1995.

AFCEC conducted an initial presence/absence (SI equivalent) PFAS field effort for the LF-1 plume

in 2016 that included sampling of existing extraction wells, influent and effluent at the associated

treatment plants, and six LF-1 monitoring wells. The existing groundwater treatment system treats

trichloroethene, tetrachloroethene, carbon tetrachloride, 1,1,2,2-tetrachloroethane, vinyl chloride,

ethylene dibromide, and 1,4-dichlorobenzene in groundwater using a granular activated carbon

(GAC) filter. PFOS was detected at concentrations exceeding the HA of 0.07 μg/L in two extraction

wells and in three monitoring wells. PFOA was detected at a concentration exceeding the HA of

0.07 μg/L in one monitoring well. A Supplemental RI was conducted between September 2015

and March 2017 that included sampling of 107 monitoring wells and eight extraction wells. The

sum of PFOS and PFOA were detected at concentrations exceeding the HA in nine monitoring

wells and two extraction wells (AFCEC, 2018a). The Supplemental RI also included sampling of

treatment plant influent and effluent ports for PFAS. PFOA/PFOS were detected at concentrations

exceeding the HA in influent at one of the treatment plants, and at concentrations below the HA

in influent at the second treatment plant. PFOA/PFOS were detected at concentrations below the

HA in effluent at one treatment plant and were not detected in the effluent at the second treatment

plant (AFCEC, 2018a).

3.4 Waste Water Treatment Plant Sand Infiltration Beds

The Waste Water Treatment Plant (WWTP) Sand Infiltration Beds are located in the northern

portion of Camp Edwards, approximately 1,550 ft southwest of the intersection of Jarvis Road

and Sandwich Road, adjacent to the Camp Edwards property boundary (Figure 3-1). The

geographic coordinates are 41.764626°N; 70.562624°W. Since 1995, the wastewater treated at

the JBCC WWTP has been conveyed to the Sand Infiltration Beds via underground piping.

Wastewater passes through the Sand Infiltration Beds and is discharged to the Cape Cod Canal.

The JBCC WWTP is addressed in Section 5.

AFCEC conducted an SI for PFAS at the WWTP Sand Infiltration Beds in 2015 that included

sampling three existing monitoring wells, the WWTP influent and effluent, the Sand Infiltration

Beds effluent, and a direct push boring near the former WWTP composting facility. PFOS and

PFOA were detected at concentrations exceeding the HA of 0.07 μg/L in two monitoring wells,

and PFOS was detected at concentrations exceeding the HA of 0.07 μg/L in the Sand Infiltration

Beds effluent, the WWTP influent, and the WWTP effluent. PFOS and PFOA were not detected

in the upgradient monitoring well (AFCEC, 2017). Additional work was completed during the

Expanded SI, which is ongoing.

3.5 Fire Station Building 3132 and Drainage Ditch #1

Fire Station Building 3132 is located in the Southeast portion of Camp Edwards, at the intersection

of Richardson Road and Bradshaw Street (Figure 3-1). The geographic coordinates of Building

3132 are 41.656330°N; 70.529865°W. Fire Station Building 3132 was built in 2007. Drainage

Ditch #1 begins approximately 440 ft west of Building 3132, along Richardson Road. The

geographic coordinates of Drainage Ditch #1 are 41.656981°N; 70.531698°W. MAARNG owns

36 percent of Building 3132, which houses the JBCC Fire Department, including nine MAARNG

firefighters, two MAARNG M1142 TFFT fire trucks, and two M1158 HEWATT tank trucks. The two

fire trucks each house a 60-gallon tank of Class A firefighting foam and a 60-gallon tank of Class

B firefighting foam. The two tank trucks each house a 50-gallon AFFF storage tank. An additional

approximately 1,500 gallons of AFFF are stored at Fire Station Building 3132.

On 25 March 2015, after responding to Tanker Truck Rollover #3 (see Section 5), about 2 gallons

of AFFF were flushed out of fire hoses to the gravel area in the northwest corner of the Fire

Station. Some AFFF may have drained into a nearby storm sewer inlet that discharges to

Drainage Ditch #1.

AFCEC conducted an SI for PFAS at Fire Station Building 3132 and Drainage Ditch #1 in 2015

through 2016 (AFCEC, 2017). Five monitoring wells and three direct push borings were

completed as part of the Focused SI. PFOS analytical results from two monitoring wells located

near Drainage Ditch #1 exceeded the HA of 0.07 μg/L. PFOS/PFOA were not detected above the

HA 0.07 μg/L in any of the three direct push groundwater borings. The Expanded SI is ongoing.

The AFCEC Remediation Program Manager indicated that there are likely ongoing releases at

Fire Station Building 3132 and Drainage Ditch #1. The Lower 40 Ramp Area (Section 5) is a

potential off-facility source of PFAS which also discharged AFFF to Drainage Ditch #1.

3.6 Open Burn Open Detonation Sites

The Open Burn Open Detonation (OB/OD) Sites are four sites located in the Training Range and

Impact Area of Camp Edwards (Figure 3-1). The four sites are Demolition Area 1, J1, J2, and J3,

and the geographic coordinates of these sites are 41.694006°N, 70.546667°W; 41.701222°N,

70.519167°W; 41.703778°N, 70.514444°W; and 41.697667°N, 70.522500°W, respectively.

Demolition Area 1 is located north of Pocasset Forestdale Road, west of Turpentine Road, and

east of Frank Perkins Road. The Demolition Area 1 site covers approximately 7.4 acres and is

located in a kettle hole that covers approximately one acre at its base. Demolition Area 1 was

used by MAARNG for the destruction of munitions and other unspecified items as well as

demolition training from the mid-1970s to the late 1980s.

Sites J1, J2, and J3 are located to the northwest of Greenway Road and to the south of Wood

Road. These three properties were occupied by a Department of Defense contractor.

There have been no documented releases of PFAS at the OB/OD Sites; however, according to 

the Environmental and Readiness Center, there is anecdotal evidence that if AFFF were used, it

would have been used at an OB/OD site.

The IAGWSP, in coordination with MassDEP and USEPA, have written the Final Sampling Work

Plan for Per- and Polyfluoroalkyl Substances (PFAS) (USACE, 2019) to address each of the four

OB/OD Sites for PFAS, and the plan is currently being executed by the IAGWSP. The Camp

Edwards IAGWSP program manager indicated that no HA exceedances were detected in the

preliminary groundwater concentration data collected to date.

6. Preliminary Conceptual Site Model

Based on the PA findings, the release areas were grouped into several AOIs. The AOIs located in

the north area are shown on Figure 6-1, and the AOIs located in the south area are shown on

Figure 6-2. The following sections describe the CSM components and the specific preliminary

CSMs developed for each AOI. The CSM identifies the three components necessary for a

potentially complete exposure pathway: (1) source, (2) pathway, and (3) receptor. If any of these

elements are missing, the pathway is considered incomplete.

In general, the potential PFAS exposure pathways are ingestion and inhalation. Human exposure

via the dermal contact pathway may occur, and current risk practice suggests it is an insignificant

pathway compared to ingestion; however, exposure data for dermal pathways are sparse and

continue to be the subject of PFAS toxicological study (National Ground Water Association

[NGWA], 2018). Receptors at Camp Edwards include site workers (e.g., camp staff and visiting

soldiers), construction workers, full-time and part-time residents outside the facility boundary,

trespassers, and recreational users. The preliminary CSMs for each AOI indicate which specific

receptors could potentially be exposed to PFAS.

6.1 AOI 1: Hangar 2816 and Building 2814

During the time period between the late 1970s and 2013, AFFF was stored at several locations

within the boundary of AOI 1 and may have been discharged to asphalt and soil. The AOI has

been identified based on preliminary data and groundwater flow directions from the AFCEC Final

Focused SI (AFCEC, 2017).

Ground-disturbing activities at the AOI could result in site worker, construction worker, and

trespasser exposure to potential PFAS contamination via inhalation of dust or ingestion of surface

soil. Ground-disturbing activities to subsurface soil also could result in site worker and

construction worker exposure.

Given the length of time since the potential AFFF releases (i.e., greater than 30 years), the

average precipitation at the facility, and high degree of soil permeability, some potential PFAS

contamination at the AOI may have migrated from the soil to groundwater via infiltration. Previous

investigation activities indicate that groundwater likely discharges to a wetlands area

approximately 6,200 ft south from Hangar 2816, which discharges to Ashumet Pond. Groundwater

passes through Ashumet Pond and continues to Johns Pond. Previous sampling activities have

identified PFOS/PFOA in surface water in Ashumet Pond and Johns Pond at concentrations

exceeding the HA (AFCEC, 2018c). Therefore, the ingestion exposure pathways for surface water

and sediment are potentially complete for residents and recreational users of Ashumet Pond and

Johns Pond (e.g., swimming and fishing).

Previous sampling activities have identified PFOS/PFOA at concentrations exceeding the HA in

groundwater at Hangar 2816 and in public drinking water supply wells to the south of the AOI

(AFCEC, 2018c). Therefore, the ingestion exposure pathway for groundwater is potentially

complete for off-facility residents and recreational users, although the source of PFAS in drinking

water to the south of the AOI is not yet identified. The preliminary CSM for Camp Edwards AOI 1

is presented on Figure 6-3.

6.2 AOI 2: LF-1

Unregulated disposal activities occurred at LF-1 from approximately 1940 to 1984, and regulated

disposal activities have occurred there from 1984 to 1995, when the landfill was capped. Among

the wastes believed to be included in LF-1 are municipal sewage sludge and fire extinguisher

fluids which may contain AFFF. The AOI has been identified based on preliminary data and
PFAS Preliminary Assessment Report

AECOM 24

groundwater flow directions from the AFCEC Final Focused SI (AFCEC, 2017). AFCEC will

continue to manage LF-1 under the current IRP. The existing groundwater extraction and

treatment system will be used to capture and treat the PFOS/PFOA within the AOI.

Ground-disturbing activities at the AOI could result in site worker, construction worker, and

trespasser exposure to potential PFAS contamination via inhalation of dust or ingestion of surface

soil. Ground-disturbing activities to subsurface soil also could result in site worker and

construction worker exposure.

Given the length of time since the potential PFAS releases (i.e., greater than 30 years), the

average precipitation at the facility, and high degree of soil permeability, some potential PFAS

contamination at the AOI may have migrated from the soil to groundwater via infiltration; AFCEC

has mapped this plume. Previous investigation activities indicate that groundwater likely

discharges to Squeteague and Red Brook Harbors in Buzzards Bay, approximately 3 miles

west/southwest from LF-1. Therefore, the ingestion exposure pathways for surface water and

sediment are potentially complete for residents and recreational users of Squeteague and Red

Brook Harbors Harbor (e.g., swimming and fishing).

Previous sampling activities have identified PFAS in groundwater at LF-1 monitoring wells, in

downgradient monitoring wells, and in extraction wells for the LF-1 treatment system. The sum of

PFOS/PFOA was detected at concentrations exceeding the HA in nine monitoring wells (all

located upgradient of the extraction fence) and two extraction wells. PFAS were not detected at

the public water supply wells when sampled for UCMR3 by the town. AFCEC currently operates

a groundwater extraction and treatment system that incidentally treats PFAS in groundwater.

Therefore, the ingestion exposure pathway for groundwater will be evaluated by AFCEC. The

preliminary CSM for Camp Edwards AOI 2 is presented on Figure 6-4.

6.3 AOI 3: WWTP Sand Infiltration Beds

During the time period between 1995 and the present, wastewater from the JBCC WWTP, which

potentially contains PFAS, has been discharged to the sand infiltration beds. The AOI has been

identified based on preliminary data and groundwater flow directions from the AFCEC Final

Focused SI (AFCEC, 2017).

Ground-disturbing activities at the AOI could result in site worker, construction worker, and

trespasser exposure to potential PFAS contamination via inhalation of dust or ingestion of surface

soil. Ground-disturbing activities to subsurface soil also could result in site worker and

construction worker exposure.

Given the average precipitation at the facility, the wastewater discharge to groundwater, and high

degree of soil permeability, some potential PFAS contamination at the AOI may have migrated

from the soil and wastewater discharge to groundwater via infiltration. Previous investigation

activities indicate that groundwater discharges to the Cape Cod Canal, approximately 480 ft

west/northwest from the AOI. Previous sampling activities have identified PFAS in groundwater

at WWTP Sand Infiltration Bed monitoring wells and in sand infiltration bed effluent at

concentrations exceeding the HA (AFCEC, 2017). Therefore, the ingestion exposure pathways

for surface water and sediment are potentially complete for residents and recreational users of

the Cape Cod Canal.

There is currently no groundwater use downgradient of the AOI between the WWTP Sand

Infiltration Beds and its discharge point at the Cape Cod Canal. Therefore, the ingestion exposure

pathway for groundwater is incomplete for the WWTP Sand Infiltration Beds. The preliminary CSM

for Camp Edwards AOI 3 is presented on Figure 6-5.

6.4 AOI 4: Fire Station Building 3132 and Drainage Ditch #1

AFFF has been stored at Fire Station Building 3132 since 2007, and AFFF potentially containing

PFAS was discharged to surface soil and Drainage Ditch #1 on 25 March 2015. AFFF also went

through the drains inside Fire Station Building 3132 and into an OWS, which drains to the WWTP.

The AOI has been identified based on preliminary data and groundwater flow directions from the

AFCEC Final Focused SI (AFCEC, 2017).

Ground-disturbing activities at the AOI could result in site worker, construction worker, and

trespasser exposure to potential PFAS contamination via inhalation of dust or ingestion of surface

soil. Ground-disturbing activities to subsurface soil also could result in site worker and

construction worker exposure.

Given the average precipitation at the facility and the high degree of soil permeability, some

potential PFAS contamination at the AOI may have migrated from the soil to groundwater via

infiltration. Previous investigation activities indicate that groundwater discharges to a wetlands

area approximately 5,200 ft south from Drainage Ditch #1, which discharges to Ashumet Pond.

Groundwater passes through Ashumet Pond and continues to Johns Pond. Previous sampling

activities have identified PFAS in surface water in Ashumet Pond and Johns Pond at

concentrations exceeding the HA. Therefore, the ingestion exposure pathways for surface water

and sediment are potentially complete for residents and recreational users of Ashumet Pond and

Johns Pond (e.g., swimming and fishing). These ponds are catch and release only due to a

mercury advisory.

Previous and ongoing sampling activities have identified PFAS in groundwater at Fire Station

Building 3132 and Drainage Ditch #1 monitoring wells at concentrations exceeding the HA, and

in public drinking water supply wells and registered community and non-community water supply

wells to the south of the AOI (AFCEC, 2018c). Therefore, the ingestion exposure pathway for

groundwater is potentially complete for off-facility residents and recreational users. The

preliminary CSM for Camp Edwards AOI 4 is presented on Figure 6-6.

6.5 AOI 5: Utilidor Fire

In 1988 or 1989, an unknown type and quantity of foam that potentially contained PFAS was

discharged to the subsurface during an underground fire in a timber-lined tunnel (utilidor) near

and south/southwest of the Chemical Spill 10 (Former BOMARC Site). The precise location is

unknown. The AOI has been identified based on preliminary data and groundwater flow directions

from previous investigations (AFCEC, 2018b).

Ground-disturbing activities at the AOI could result in site worker, construction worker, and

trespasser exposure to potential PFAS contamination via inhalation of dust or ingestion of surface

soil. Ground-disturbing activities to subsurface soil also could result in site worker and

construction worker exposure.

Given the length of time since the foam release, the average precipitation at the facility, and the

high degree of soil permeability, some potential PFAS contamination at the AOI may have

migrated from the soil to groundwater via infiltration. Previous investigation activities indicate that

groundwater discharges to Ashumet Pond, approximately 2.9 miles south of the Chemical Spill

10 (Former BOMARC Site). Groundwater passes through Ashumet Pond and continues to Johns

Pond. Chemical Spill 10 (Former BOMARC Site) previous sampling activities have identified

PFAS in surface water in Ashumet Pond and Johns Pond at concentrations exceeding the HA.

Therefore, the ingestion exposure pathways for surface water and sediment are potentially

complete for residents and recreational users of Ashumet Pond and Johns Pond (e.g., swimming

and fishing).
PFAS Preliminary Assessment Report

Camp Edwards, Massachusetts

AECOM 26

The AFCEC Remediation Program Manager stated that sampling of the Chemical Spill 10 (Former

BOMARC Site) has been completed and the groundwater results did not indicate any PFAS

impacts. Therefore, it is unlikely that the foam used in emergency response at the utilidor fire

contained PFAS. However, previous sampling activities have identified PFAS in groundwater at

downgradient monitoring wells as well as in public drinking water supply wells and registered

community and non-community water supply wells to the south of the utilidor fire (AFCEC, 2018c).

Therefore, the ingestion exposure pathway for groundwater is potentially complete for off-facility

residents and recreational users. The preliminary CSM for Camp Edwards AOI 5 is presented on

Figure 6-7.

6.6 AOI 6: OB/OD Sites

Though there is no direct evidence of AFFF usage documented. However, there has been

suggested anecdotal evidence that if AFFF were used, it would have been used at an OB/OD Site

(USACE, 2019). The Camp Edwards IAGWSP is conducting an ongoing PFAS investigation at

the OB/OD Sites, which will evaluate the presence of PFAS compounds as well as potential

exposure pathways. The preliminary CSM for Camp Edwards AOI 6 is presented on Figure 6-8.

7. Conclusions

This report presents a summary of available information gathered during the PA on the use and

storage of AFFF and other PFAS-related activities at Camp Edwards. The PA findings are based

on the information presented in Appendix A and Appendix B.

7.1 Findings

The AFCEC IRP is performing ongoing PFAS-related activities at AOI 1 through AOI 5 and other

sites; future actions at these AOIs will continue to be managed by the AFCEC IRP. For AOI 6, the

IAGWSP in coordination with MassDEP and the USEPA have written the Final Sampling Work

Plan for Per- and Polyfluoroalkyl Substances (PFAS) (USACE, 2019) to address each OB/OD

Site for PFAS. Figure 7-1 and Figure 7-2 present a summary of PA findings (Table 7-1).

Thirteen potential off-facility sources of PFAS were considered in the local area surrounding Camp

Edwards. Descriptions of these sources are presented in the AFCEC JBCC PFAS Program

Summary (Appendix A; AFCEC, 2020). 

Based on the potential AFFF releases documented at Camp Edwards and the contiguous

surrounding JBCC area, there is potential for exposure to PFAS contamination in soil,

groundwater, surface water, and sediment for the following potential receptors: site workers (e.g.,

Camp Edwards military and non-military staff and visitors), onsite construction workers, fulltime

and part-time residents outside the facility boundary, trespassers, and recreational users. In

addition, residents using groundwater for drinking water surrounding the facility may be exposed

to migrating PFAS contamination via the nearby groundwater pathway. The groundwater ingestion

pathway is potentially complete for off-facility residents to the south, southeast, southwest, and

west of Camp Edwards. Receptors are less likely to be exposed to potential PFAS contamination

through direct contact with soil and inhalation via air; however, some PFAS chemicals are water 

soluble and can migrate readily from soil to groundwater or surface water via leaching and runoff. Therefore, there is a potential for PFAS contamination in soil to migrate to groundwater and

surface water systems.

7.2 Uncertainties

A number of information sources were investigated during this PA to determine the potential for

PFAS-containing materials to have been present, used, or released at the facility. Historically,
PFAS Preliminary Assessment Report

Camp Edwards, Massachusetts

AECOM 36

documentation of PFAS use was not required because PFAS were considered benign. Therefore,

records were not typically kept by the facility or available during the PA on the use of PFAS in

training, firefighting, or other non-traditional activities, or on its disposition.

The conclusions of this PA are based on all available information, including previous

environmental reports, observations made during the visual site inspection, and interviews.

Interviews of personnel with direct knowledge of a facility generally provided the most useful

insights regarding a facility's historical and current PFAS-containing materials. Sometimes the

provided information was vague or conflicted with other sources. Gathered information has a

degree of uncertainty due to the absence of written documentation, the limited number of

personnel with direct knowledge due to staffing changes, the time passed since PFAS were first

used (1969 to present), and a reliance on personal recollection. Inaccuracies may arise in

potential PFAS release locations, dates of release, volume of releases, and the concentration of

AFFF used. There is also a possibility the PA has missed a source of PFAS, as the science of

how PFAS may enter the environment continually evolves.

In order to minimize the level of uncertainty, readily available data regarding the use and storage

of PFAS were reviewed, retired and current personnel were interviewed, multiple persons were

interviewed for the same potential source area, and potential source areas were visually

inspected.

Table 7-2 summarizes the uncertainties associated with this PA:

Table 7.2. Uncertainties within the PA

Area of Interest Source of Uncertainty

All AOIs

Camp Edwards interviewees did not recall the type or brand of firefighting

foam historically used; it is not known if the generic use of the term “foam”

by interviewees may have, in some instances, been in reference to AFFF

or other non-PFAS containing firefighting foams or wetting agents.

AOI 1: Hangar

Exact locations of potential PFAS releases were not recalled during

interviews. Interviewees recalled conflicting locations for the CAFS

training area and where the fire truck was parked.

Interviewees could not identify the content or quantity of disposed material

in unregulated disposal areas. It is unclear from interviews if disposed

municipal sewage sludge and fire extinguisher fluid contain PFAS.

The quantity of PFAS in influent released from off-facility sources is

unknown.

AOI 4: Fire

Interviewees could not recall the exact amount or extent of off-facility

source release into Drainage Ditch #1 or exact location and extent of

potential release from line flushing into Drainage Ditch #1.

AOI 5: Utilidor

Interviewees did not recall the type or quantity of foam discharged into

the subsurface during the underground fire or the exact location and

extent of the potential release.

AOI 6: OB/OD

Sites (J1, J2, J3,

and Demolition

Area 1)

Exact locations and quantities of AFFF use unknown. Interviewees were

unavailable to confirm anecdotal evidence regarding AFFF use.

7.3 Potential Future Actions

Interviews and records (covering from the 1940s to present) indicate that current or former ARNG

activities may have resulted in potential PFAS releases at the six AOIs identified during the PA.
PFAS Preliminary Assessment Report

Camp Edwards, Massachusetts

AECOM 37

Based on the preliminary CSMs developed for the AOIs, there is potential for human receptors to

be exposed by direct or indirect pathways to PFAS contamination by inhalation of soil dust or

ingestion of soil, groundwater, surface water, and sediment at these AOIs. Table 7-3 summarizes

the rationale used to determine if the AOIs should be considered for further investigation under

the CERCLA process and undergo an SI.

The AFCEC IRP is performing ongoing PFAS-related activities at AOI 1 through AOI 5; future 

actions at these AOIs will continue to be managed by the AFCEC IRP. The ARNG IAGWSP being

executed under the SDWA is currently working with the MassDEP and USEPA on a

comprehensive PFAS investigation work plan to collect groundwater samples at several sites on

Camp Edwards, including at AOI 6. ARNG will evaluate the need for an SI at AOI 6 at Camp

Edwards based on the potential receptors, the potential migration of PFAS contamination off the

facility, and the availability of resources. Any future investigations related to PFAS at AOI 6 will be

managed by the IAGWSP.

Conceptual Site Model Information
Preliminary Assessment – Conceptual Site Model Information

Site Name: Camp Edwards

Why has this location been identified as a site? Facility is a training site with multiple vehicle 

maintenance and fueling areas. AFFF was stored in vehicles or plastic containers, and released in training

Exercises and emergency responses.

Are there any other activities nearby that could also impact this location? Yes. AFFF releases from

adjacent locations on JBCC related to AFF storage, emergency response actions, ANG facility, and

waste/sewage water treatment.

Training Events

Have any training events with AFFF occurred at this site? Yes

If so, how often? Annually from late 1970s through 2013.

How much material was used? Is it documented? Unknown quantity. Contents of foam discharge 

during training events could not be identified. Unknown quantity.

Identify Potential Pathways: Do we have enough information to fully understand over land surface 

water flow, groundwater flow, and geological formations on and around the facility? Any direct 

pathways to larger water bodies?

Surface Water:

Surface water flow direction? South towards wetlands and Ashumet Pond; west towards Buzzards 

Bay; north towards Cape Cod Canal and Cape Cod Bay.

Average rainfall? 45.16 inches annual precipitation per year

Any flooding during rainy season? No

Direct or indirect pathway to ditches? Yes

Direct or indirect pathway to larger bodies of water? Yes. Wetlands areas, Ashumet Pond, Johns Pond, 

Cape Cod Canal.

Does surface water pond any place on site? Yes, in various wetlands areas

Any impoundment areas or retention ponds? No

Any NPDES location points near the site? Yes

How does surface water drain on and around the flight line? N/A
Preliminary Assessment – Conceptual Site Model Information

Groundwater:

Groundwater flow direction? To south in southern portion; to west in western portion, and to north 

in northern portion of Camp Edwards and JBCC.

Depth to groundwater? Unknown. Maximum hydraulic-head altitude observed at approximately 70 

ft msl. Surface water bodies generally connected to groundwater.

Uses (agricultural, drinking water, irrigation)? Public water supply, registered community and noncommunity water supply, private water supply, drinking water

Any groundwater treatment systems? Landfill #1, Hunter Avenue, CS-10, CS-10 Mobile Treatment 

Unit, FS-12, Sandwich Road, FS-1, Ashumet Valley, FS-28

Any groundwater monitoring well locations near the site? Yes, many monitoring wells within JBCC 

and adjacent areas for ongoing investigations

Is groundwater used for drinking water? Yes. Groundwater is the sole source of drinking water in the 

area.

Are there drinking water supply wells on installation? Yes

Do they serve off-post populations? Yes

Are there off-post drinking water wells downgradient? Yes. PFAS have been detected in some 

downgradient public and private water supply and drinking water wells.

Waste Water Treatment Plant:

Has the installation ever had a WWTP, past or present? No. Camp Edwards wastewater is treated at 

the JBCC WWTP at intersection of Kittridge Road and Boron Drive, on ANG property. WWTP 

sand infiltration beds for treated wastewater located on north installation boundary.

If so, do we understand the process and which water is/was treated at the plant? Yes. Wastewater from 

JBCC is treated and discharged to sand infiltration beds.

Do we understand the fate of sludge waste? Sludge waste from the JBCC WWTP was disposed at the 

former sewage treatment plant and current WWTP on ANG property. Sludge waste was also

disposed in Landfill #1.

Is surface water from potential contaminated sites treated? No.

Equipment Rinse Water

1. Is firefighting equipment washed? Where does the rinse water go?

Firefighting equipment has been washed at Building 2814, Building 3132, and in the flight line area 

of Otis ANG Base. Rinse water collected in storm sewers and drainage ditches. Possible historical 

releases to ground surface and asphalt.

2. Are nozzles tested? How often are nozzles tested? Where are nozzles tested? Are nozzles cleaned after 

use? Where does the rinse water flow after cleaning nozzles?

Some nozzle testing/cleaning has occurred at Building 2814, Building 3132, and in the flight line 

area of Otis ANG Base. Rinse water flows to storm sewers and drainage ditches, as well as to 

ground surface and asphalt.

3. Other? N/A

Identify Potential Receptors: 

Site Worker Yes

Construction Worker Yes

Recreational User Yes

Residential Yes

Child Yes

Ecological Yes

Note what is located near by the site (e.g. daycare, schools, hospitals, churches, agricultural, livestock)?

Recreational lakes, wetlands, woodlands; residents; Cape Cod Canal

Documentation 

Ask for Engineering drawings (if applicable). No engineering drawings were provided.

Has there been a reconstruction or changes to the drainage system? When did that occur?

Hangar 2816 drains previously flowed to dry wells on site. The drainage system was reconstructed 

to discharge to storm sewer (date unknown).
