Executive Summary

The United States (US) Army Corps of Engineers (USACE) Baltimore District, on behalf of the

Army National Guard (ARNG)-Installations and Environment Division (IED), Cleanup Branch,

contracted AECOM Technical Services, Inc. (AECOM) to perform Preliminary Assessments (PAs)

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

(PFOA) Impacted Sites at ARNG Facilities Nationwide. 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.

AECOM completed a PA for PFAS at the former Crash Fire Station, former Building 241 (also

referred to as “the facility”) in Newington, New Hampshire, to assess potential PFAS release areas

and exposure pathways to receptors. The performance of this PA included the following tasks:

· Reviewed data resources to obtain information relevant to suspected PFAS releases;

· Conducted a site visit on 23 April 2019;

· Interviewed current Pease Air National Guard Base (ANGB) personnel and the Pease

ANGB environmental manager during the site visit;

· Completed visual site inspections (VSIs) at known or suspected PFAS release locations and

documented with photographs.

During this PA, AFFF releases were identified at the former Crash Fire Station during use by the

United States Air Force (USAF) at the former Pease Air Force Base (AFB) and later during use

by the New Hampshire Air National Guard (NHANG) at the Pease ANGB. No releases have

occurred since the property was transferred to the New Hampshire Army National Guard

(NHARNG) in 2013. The former Crash Fire Station is shown on Figure ES-1 and described below:

In July 2015, the United States Environmental Protection Agency (USEPA) issued the

Administrative Order for Response Action Docket Number SDWA-01-2015-0061 to the USAF,

which requires investigation and mitigation of PFAS-related impacts to groundwater at the former

Pease AFB (USEPA, 2015). The USAF is currently conducting PFAS response activities at the

former Pease AFB in response to the Administrative Order. The releases to soil and groundwater

at the former Crash Fire Station were evaluated by the USAF as part of a basewide PA and SI for

the former Pease AFB. At the time of this PA, the USAF has taken the lead in addressing the

AFFF releases at the former Crash Fire Station as part of the ongoing response effort.

1. Introduction

Authority and Purpose

The United States (US) Army Corps of Engineers (USACE) Baltimore District, on behalf of the 

Army National Guard (ARNG)-Installations and Environment Division, Cleanup Branch, 

contracted AECOM Technical Services, Inc. (AECOM) to perform Preliminary Assessments (PAs) 

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

(PFOA) Impacted Sites at ARNG Facilities Nationwide under Contract Number W912DR-12-D0014, Task Order W912DR17F0192, issued 11 August 2017, and Modification 01 issued 30 

September 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 compounds 

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

evolve. The US Environmental Protection Agency (USEPA) issued Drinking Water lifetime Health 

Advisories (HAs) of 70 parts per trillion (ppt), individually or combined, for PFOA and PFOS in 

May 2016, but there are currently no promulgated national standards regulating PFAS in drinking 

water (USEPA, 2016a; USEPA, 2016b). In the absence of federal maximum contaminant levels 

(MCLs), some states have adopted their own drinking water standards for PFAS. In June 2019, 

the New Hampshire Department of Environmental Services (NHDES) issued Final Proposed 

MCLs and Ambient Groundwater Quality Standards (AGQS) for four PFAS compounds. The 

drinking water rule amendments were subsequently adopted by the New Hampshire Joint 

Legislative Committee on Administrative Rules to be effective on 30 September 2019 ( New 

Hampshire Code of Administrative Rules, 2019). The MCLs/AGQS are as follows:

· PFOA: 12 ppt

· PFOS: 15 ppt

· PFHxS: 18 ppt

· PFNA: 11 ppt

This report presents findings of a PA for PFAS at the former Crash Fire Station (former Building 

241; also referred to as “the facility”) in Newington, New Hampshire, in accordance with the 

Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA; USEPA, 

1980), as amended, the National Oil and Hazardous Substances Pollution Contingency Plan (40 

Code of Federal Regulations Part 300; USEPA, 1994a), and USACE requirements and guidance.

Facility Location and Description

The former Crash Fire Station (former Building 241) is located adjacent to the ANGB and the 

Portsmouth International Airport, within the Pease International Tradeport in the town of 

Newington, Rockingham County, New Hampshire (Figure 1-1). The property is bordered on the 

east by the city of Portsmouth, on the north by the Pease ANGB and the town of Newington, and 

on the southeast by the town of Greenland. The approximate center of the facility is located at 

43°05'1.69" North (N); 70°49'6.04" West (W), at 109 feet (ft) above mean sea level (amsl). 

According to the 2017 census, the town of Newington has a population of approximately 789 

people, and the city of Portsmouth has a population of approximately 21,796 people (US Census, 

2018). 

The property was originally developed in the early 1930s by the city of Portsmouth as a municipal 

airport (CDM and Rivers 1993). During World War II, the US Navy leased the 300-acre municipal 

airport from the city. In 1946, rights to the airfield were transferred to the US Air Force (USAF) for 

use by the Strategic Air Command. Additional land was acquired by the USAF in 1952 and 1953, 

with construction of Pease Air Force Base (AFB) beginning in 1954 (Earth Tech, 1995). At its 

maximum extent, the former Pease AFB occupied approximately 4,365 acres (Amec Foster 

Wheeler, 2016). The NHANG first arrived at Pease AFB in 1966. 

Pease AFB was closed in 1991 as part of the Secretary of Defense's Commission on Base 

Realignment and Closure (BRAC). As a result of the base closure, the New Hampshire legislature 

created the Pease Development Authority (PDA) to develop a plan for the reuse and 

redevelopment of the base (EarthTech, 1995; ANG, 2005). Most of the former AFB was 

transferred to the PDA for reuse as a civilian airport and commercial center. Approximately 1,100 

acres were transferred to the US Department of Interior for use as a national wildlife refuge 

(NHDES, 2014), and 229 acres became Pease ANGB (Amec Foster Wheeler, 2016). 

The facility, known as Parcel A of Tract 1 (of former Pease AFB), was developed with the former 

Building 241 in 1956 as part of Pease AFB, according to the 2005 Environmental Baseline Survey 

(ANG, 2005). The Pease AFB used the former Building 241 from 1954 to 1990, when the property 

was licensed to the state of New Hampshire for use by the NHANG. The NHANG used the building 

from 1992 until 2006 as a Crash/Fire response facility for base operations (ANG, 2005). In 2006, 

the facility was vacated, as the Crash/Fire Response activities were relocated to the newlyconstructed Fire Station on the base. The building remained vacated for part of this period but 

was then utilized by the PDA to provide covered storage of ground support equipment for the local 

airport operations. In August 2011, the USAF issued a formal notice of intent to dispose the 3.5-

acre parcel. The NHARNG subsequently submitted a Real Estate Action Plan, indicating its 

intentions to acquire the facility for stationing of one of its units (NHARNG, 2012). The property 

was officially transferred to the NHARNG in June 2013 (Appendix A). Aside from demolishing the 

building in December 2016, the property has not yet been used by the NHARNG. 

The facility is currently closed to the public by a 6-ft chain-link fence surrounding the facility. During 

the time of the VSI, the property was used by the US Navy for the storage of Conex boxes. 

Facility Environmental Setting

The following sections describe the environmental setting of the facility and include information 

on geology, hydrogeology, hydrology, climate, and current and future land use.

1.5.1 Geology

The facility is located on a peninsula in the Piscataqua River drainage basin, which is bounded 

by the Atlantic Ocean to the east and the New England upland section to the west (Amec Foster 
PFAS Preliminary Assessment Report

Former Crash Fire Station (Building 241)

Newington, New Hampshire

6

Wheeler, 2015). The facility is situated in the approximate center of the peninsula on a relatively

flat kame plain. Generally, the land surface slopes radially downward in all directions on the

peninsula.

The soils in the vicinity of the facility are unconsolidated glacial deposits consisting of unsorted

clay, silt, sand, gravel, cobbles, and boulders. The unconsolidated sedimentary deposits are

separated into six stratigraphic units (fill, upper sand unit, marine clay and silt, lower sand unit,

and glacial till unit). These units were deposited during the Pleistocene glaciation and the

associated flooding of coastal areas by rising ocean water levels. The units are laterally

discontinuous across the base and range in thickness from zero to greater than 100 ft (ANG,

2005; AECOM, 2015). The upper sand and lower sand are indistinguishable, except where the 

marine clay and silt separate the two units. The sand units consist of fine to coarse sand with

trace fine gravel and silt. The marine clay and silt vary from pure clay to a silt and clay interbedded

with sand. The thickness of the clay unit ranges from zero to 55 ft across Pease ANGB. The

contact between the lower sand and the glacial till is often gradational. Where the lower sand can

be identified, it ranges in thickness from a few ft to approximately 37 ft. The till at the facility

consists of either a compact, poorly sorted silt and clay with abundant facetted and rounded

gravel, or a less compact, more sand-rich deposit with angular to subangular gravel. The glacial

till is up to 39 ft thick and is discontinuous across the facility (ANG, 2005).

Bedrock beneath the facility is associated with the Merrimack Trough, one of the groups of

northeast-trending rocks with folded and metamorphosed features. The facility is divided between

the Eliot Formation to the north and Kittery Formation to the south. Both formations are of

Ordovician to Silurian age generally composed of phyllite, quartize, and metasandstone. The

surface of the bedrock is locally weathered, both chemically and physically. While below the

weathered zone, the bedrock is variably fractured.

1.5.2 Hydrogeology

Groundwater in the area occurs in unconsolidated material, fractured bedrock, and competent

bedrock and is typically 5 to 25 ft below ground surface (bgs). Depth to groundwater varies

because of natural and human factors such as precipitation and pumping rates. Overburden

(shallow) groundwater regionally flows east to southeast, while bedrock (deep) predominantly

moves southeast (Figure 1-2). The principal water-bearing overburden units are the Upper Sand

and Lower Sand, which merge under the flight line to form a 40 to 60 ft-thick section of saturated,

permeable sand (Shaw, 2013). The marine clay and silt and the glacial till, where present, may

act as local confining layers that retard vertical groundwater flow. Where natural aquitard units

are discontinuous, the shallow bedrock, which is highly permeable, can be considered part of the

water table aquifer along with the overburden deposits.

The presence of groundwater in the competent bedrock is dependent on secondary porosity,

which is a function of fractures, bedding planes, and joint sets. Tidal fluctuations can be measured

in both water table wells and bedrock wells (ANG, 2005). Groundwater elevations also vary

seasonally, with groundwater highs from December to May, and lows from July to September

(ANG, 2005). Available groundwater data indicate that groundwater flow in the vicinity of the

former Crash Fire Station is to the southeast. Groundwater elevations in January 2016 ranged

from approximately 73.90 to 66.30 ft amsl in the Upper Sand and from 73.53 to 61.42 ft amsl in

the Lower Sand (Amec Foster Wheeler, 2017). The approximate depth to groundwater in the

vicinity of the facility is 15 ft bgs.

Currently, the Portsmouth Water System supplies the former Pease AFB property with potable

water, in addition to the following municipalities: Greenland, New Castle, Newington, Portsmouth,

and Rye (Tighe & Bond, 2013). The water system is supplied by the Bellamy Reservoir and three

groundwater wells via the Madbury Water Treatment Plant, located approximately 8 miles
PFAS Preliminary Assessment Report

Former Crash Fire Station (Building 241)

Newington, New Hampshire

7

northwest of the installation, and six groundwater wells located throughout the municipalities

mentioned above. The Harrison and Smith wells are still in service and are located on the former

Pease AFB property; the Collins and Portsmouth wells are located within 0.5 miles southeast of

the installation, and the Greenland well is located approximately 1.7 miles southwest of the

installation. The Haven well was in operation until May 2014, after which it was shut down due to

detectable levels of PFAS, including PFOS above USEPA HA (Amec Foster Wheeler, 2015).

Locations of the wells are shown on Figure 1-2.

Third Unregulated Contaminant Monitoring Rule (UCMR 3) data were reviewed as part of the PA.

UCMR 3 samples were collected at four locations within the Portsmouth Water System, including

the Collins Well Treatment Site (Figure 1-2), Portsmouth Well Treatment Site (Figure 1-2),

Greenland Well Treatment Site (approximately 4.5 miles southeast of the facility), and the

Madbury Water Treatment Plant. All samples were nondetect for PFAS within the Portsmouth

Water System (USEPA, 2017).

1.5.3 Hydrology

The facility is located on a peninsula in the Piscataqua River Basin, approximately 2 miles

southwest of the Piscataqua River (Figure 1-3). The river is a 13-mile long, tidally-influenced river

that drains approximately 1,020 square miles of southern Maine and southeastern New

Hampshire, prior to discharging to the Atlantic Ocean (ANG, 2005). The Great Bay, a 6,000-acre

tidal estuary, is located approximately 1.5 miles west of the facility and flows into the Piscataqua

River. The North Mill pond, also tidally influenced, is located approximately 2.5 miles east of the

facility and also discharges to the Piscataqua River.

The surface water runoff at the former Pease AFB has been altered from natural conditions by

facility infrastructure and is collected by a series of manmade ditches, storm sewers, and drainage

swales, which all leave the base in outfalls, streams, or brooks to one of three receiving bodies of

water: the Great Bay, the Little Bay, or the Piscataqua River (ANG, 2005). The former Crash Fire

Station is potentially located near a surface water flow divide. Stormwater runoff from the entire

Pease ANGB flightline and, in particular, the area where the Pease ANGB aircraft are parked

(approximately 250 ft west of the former Crash Fire Station), drains through underground pipes

and one of two oil/water separators (OWSs) to an OWS on the west side of the runway. Water is

then discharged to McIntyre Brook, which flows into the Great Bay. Stormwater from the Pease

ANGB around Hangars 251 and 252 (north of the former Crash Fire Station) drains through open

ditches and underground pipes to the vicinity of Hodgson Brook, where it discharges to the North

Mill Pond and then to the Piscataqua River (ANG, 2005).

According to Federal Emergency Management Agency Flood Insurance Rate Maps for the region,

there are no 100- or 500-year floodplains on the facility (ANG, 2005). Several wetland studies

were performed on the former Pease AFB as part of its closure (USAF, 1995). The National

Wetlands Inventory Map indicates that wetlands are not present at the facility; however, there is 

a small parcel of wetland area present approximately 1,000 ft to the northeast along Newington

Street and New Hampshire Avenue (ANG, 2005). Additionally, numerous wetlands are located

throughout the former Pease AFB. These wetlands are generally groundwater recharge features

that collect and attenuate surface water runoff (Amec Foster Wheeler, 2016).

The Great Bay National Wildlife Refuge, located 1.5 miles west of the facility, comprises over

1,000 acres and is the largest parcel of protected conservation land on the Great Bay. The refuge

includes many diverse habitats including oak hickory forests, grasslands, shrub thickets, fresh

and saltwater wetlands, marshes, and open water habitats, all where wild plants and animals

thrive, including several state-listed rare and endangered species (Amec Foster Wheeler, 2016).

1.5.4 Climate

The facility lies within the humid continental climate zone, which is characterized by long, cold,

snowy winters, very warm (and at times humid) summers, and relatively brief autumns and

springs. The monthly daily average temperature ranges from a high of 33 degrees Fahrenheit (°F)

in January to 83°F in July. In winter, successive storms deliver light to moderate snowfall amounts

that contribute to the relatively reliable snow cover. Summer can bring stretches of humid

conditions as well as thunderstorms. Average annual rainfall is 46 inches, and average annual

snowfall is approximately 45 inches (US Climate Data, 2019). The region has a fairly even

distribution of precipitation throughout the year, as measurable amounts of precipitation typically

occur one out of three days (ANG, 2015).

1.5.5 Current and Future Land Use

The facility is not currently being used by the NHARNG and is closed to the public by a 6-ft chainlink fence surrounding the facility. During the time of the VSI, the property was being used by the

US Navy for the storage of Conex boxes. According to NHARNG personnel, the NHARNG may

construct a new facility on the property, but no plans have been finalized at the time of this PA.

The surrounding properties include the Pease ANGB, the Portsmouth International Airport, and

the Pease International Tradeport. The Portsmouth International Airport shares its runway with

the Pease ANGB and operates both domestic and international passenger service. The Pease

International Tradeport is a 3,000-acre business and industrial park that is home to over 200

businesses including technology companies, insurance firms, and goods manufacturers, among

many others.

The surrounding area also includes the following residential communities: many schools,

daycares, medical facilities, and multiple commercial centers. The Great Bay National Wildlife

Refuge is located 1.5 miles west of the property and comprises over 1,000 acres of protected

conservation. Future land use in the surrounding area is anticipated to remain the same.

2. Fire Training Areas

No FTAs were identified within the former Crash Fire Station property boundary during the PA

through interviews (Appendix B), historical document review, or Environmental Data Resource,

Inc. (EDR) Reports (Appendix A; EDR, 2019). Historic fire training activities occurred at two offfacility areas, which are discussed in Section 5 of this PA Report. According to interviewees,

current fire training activities are conducted at the New Hampshire Fire Academy (also known as

the Richard M. Flynn Fire Academy) in Concord, New Hampshire.

3. Non-Fire Training Areas

One non-FTA where AFFF was stored and/or released was identified during the PA. A description 

of the non-FTA is presented below, and the location is shown on Figure 3-1. 

Former Crash Fire Station

The former Crash Fire Station (former Building 241) was located on the flightline of the Portsmouth 

International Airport at Pease, New Hampshire, south of the control tower, at approximately 

43°05'1.69"N; 70°49'6.04"W. The station was in service from 1954 to 2006 and was first used by 

the former Pease AFB, followed by the Pease ANGB. In 2006, the facility was vacated by the 

NHANG Fire Department (FD), as the Crash/Fire Response activities were relocated to the newlyconstructed Fire Station on the Pease ANGB. The property was transferred to the NHARNG in 

June 2013, and the building was demolished in 2016. The NHARNG did not use AFFF or PFAScontaining materials at the former Crash Fire Station. No activities conducted by the NHARNG 

would have resulted in a release of PFAS. 

According to interviews with NHANG FD personnel, the former Crash Fire Station did not have a 

fire suppression system. Two Aircraft Rescue Fire Fighting (ARFF) vehicles were housed at the 

former Crash Fire Station, which are still in use at the new NHANG FD today. Photos of the 

vehicles are included in Appendix C. AFFF was transferred into the respective ARFF vehicles at 

the station from trailers, which were used as secondary containment. No documentation or 

procurement records were kept for AFFF, but 3% AFFF was always used. At the time of the 

closure of the former Crash Fire Station, 3% Ansulite AFFF was being used.

NHANG FD personnel also indicated that the ARFF trucks often had small leaks (approximately 

less than 1 gallon per week). The leaks were sometimes contained in buckets when the vehicles 

were parked inside the station. When the vehicles were parked outside the station, leaks would 

discharge to the parking apron. The vehicles were never parked on the grass. The station also 

contained a wash rack. Because AFFF has surfactant-like properties, AFFF was occasionally 

used to wash the vehicles at the wash rack when soap was not available. Surface drainage from 

the former station would have been collected by the storm water collection system along the flight 

line and routed to the storm water outfall at McIntyre Brook. AFFF spilled inside the building, and 

runoff from the truck washing would have been contained in the building and collected by the 

building sanitary sewer piping, ultimately being discharged to the former Pease AFB municipal 

Waste Water Treatment Plant (WWTP). 

The USAF began initiatives in 2012 to assess the presence of PFAS at BRAC installations in 

accordance with Department of Defense (DoD) Instruction 4715.18, Emerging Contaminants 

(DoD, 2009). Additionally, in July 2015, the USEPA issued the Administrative Order for Response 

Action Docket Number SDWA-01-2015-0061, which requires investigation and mitigation of 

PFOS and PFOA related impacts to groundwater at the former Pease AFB (USEPA, 2015). As 

part of this effort, a Perfluorinated Compounds PA was prepared for the former Pease AFB (Amec 

Foster Wheeler, 2015), and a basewide SI was subsequently conducted (Amec Foster Wheeler, 

2017). The former Crash Fire Station (former Building 241) was included in the basewide PA and 

SI.

Consistent with the findings of the interviews conducted as part of this PA, the USAF PA found 

that AFFF was stored at the station from 1974 to the closure of the installation. No AFFF was 

purposely released at the station, and no equipment testing or calibration were performed. PFAS 

may have been inadvertently released from spilled AFFF and runoff from the truck washing, which 

would have been contained in the building and ultimately discharged to the former Pease AFB 

municipal WWTP (Amec Foster Wheeler, 2015).

Soil and groundwater samples were collected at the former Crash Fire Station as part of the 2017

SI. PFAS were detected in soil and groundwater at elevated concentrations. In groundwater,

PFOS was detected at 1000 J (estimated value) to 19,000 ppt, and PFOA was detected at 160 to

1500 ppt, all of which exceed the current USEPA HA of 70 ppt and the New Hampshire

MCLs/AGQS of 15 ppt (PFOS) and 12 ppt (PFOA). The SI Report also concluded that the

distribution of PFAS across the former AFB in combination with the flow patterns derived from the

groundwater model suggested that the former Crash Fire Station was one of four areas that were

the primary contributors to PFAS concentrations in groundwater at Pease (Amec Foster Wheeler,

2017).

In June 2018, an Action Memorandum was prepared to document the approval and decision by

the USAF to conduct an ERA in response to the presence of PFOA and PFOS in private drinking

water wells in Newington, New Hampshire and surrounding areas of the former Pease AFB

(USAF, 2018). The USAF is continuing to address PFAS at the former Crash Fire Station as part

of the ongoing PFAS response activities at the former Pease AFB, in accordance with USEPA

Administrative Order SDWA-01-2015-0061. An Airfield Interim Mitigation System (AIMS) is

currently being implemented in response to the Administrative Order to treat groundwater in the

vicinity of the airfield, including the groundwater at the former Crash Fire Station.

4. Emergency Response Areas

No emergency response areas were identified within the former Crash Fire Station property

boundary during the PA through interviews (Appendix B) or historical document review. One

adjacent, off-facility emergency response area was identified and is discussed in Section 5 of this

PA Report.

5. Adjacent Off-Facility Sources

Several potential off-facility sources of PFAS adjacent to the former Crash Fire Station, not under 

the control of the ARNG, were identified during the PA. Based on interviews with Pease ANGB 

personnel (Appendix B) and historical document review, all identified adjacent areas with 

potential AFFF releases are within the former Pease AFB boundary. Descriptions of the adjacent 

sources are presented below and are shown on Figure 5-1. 

Former Pease Air Force Base

The former Pease AFB is located at approximately 70°49'24"N; 43°04'41"W in the communities 

of Portsmouth and Newington in Rockingham County, New Hampshire. The installation was in 

operation by the USAF from 1956 to 1991 and occupied approximately 4,365 acres (Amec Foster 

Wheeler, 2016). 

Two fire stations were located at the installation: the former Crash Fire Station (discussed in 

Section 3), which was tasked to respond to fires associated with aircraft crashes, and the former 

Municipal Fire Station, which was primarily tasked to respond to municipal fires. The former 

Municipal Fire Station was located at the corner of Rye Street and International Drive (Figure 5-

1). Crash station vehicles were never stored, maintained, or washed in the former Municipal Fire 

Station; this location was strictly a structural substation that did not store or utilize AFFF (Amec 

Foster Wheeler, 2016). The Portsmouth FD reopened the former Pease AFB municipal firefighting 

station in 1993 (Portsmouth FD, 2014).

The NHANG FD at Pease ANGB currently operates a crash fire station on the flight line. The 

current crash fire station was opened in 2006 and is located north of the control tower. Operations 

were moved from the former Crash Fire Station at that time. Two AFFF-capable fire engines are 

housed at the NHANG FD. The NHANG FD stores AFFF at the current crash fire station in the 

two engines and two mobile trailers (Appendix C). 

Fire suppression systems are currently installed in eight hangars on the Pease ANGB. NHANG 

hangars 251, 253, and 254 have high expansion foam (HEF) suppression systems. The former 

PAN-AM hangar, which is the largest hangar on the installation, contains a deluge suppression 

system that utilizes water. The Tyco, PlaneSense, and two Port City Air hangars also have 

suppression systems; however, the type of suppressant utilized (either HEF or AFFF) is currently 

unknown (Amec Foster Wheeler, 2015).

As described in Section 3, the USAF began initiatives to assess the presence of PFAS at the 

former Pease AFB in 2012. Additionally, in July 2015, the USEPA issued the Administrative Order 

for Response Action Docket Number SDWA-01-2015-0061, which requires investigation and 

mitigation of PFOS and PFOA related impacts to groundwater at the former Pease AFB (USEPA, 

2015). In response to the Administrate Order, a Perfluorinated Compounds PA was prepared 

(Amec Foster Wheeler, 2015) and a basewide SI was subsequently conducted (Amec Foster 

Wheeler, 2017). The results of the PA indicated that AFFF containing PFAS was used and stored 

at the former Pease AFB and was routinely used during training exercises and to extinguish 

petroleum fires. In addition, AFFF was inadvertently released on several occasions at several 

locations. AFFF areas associated with the former Pease AFB are shown on Figure 5-1 (Amec 

Foster Wheeler, 2015) and are described below: 

· Installation Restoration Program Site AT008, former Fire Training Area 2 (herein referred to

as “Site 8” or FTA-2): The former Pease AFB FD utilized two FTAs during operational years.

FTA-1 was utilized from 1956 to 1961 (prior to the time PFAS were first used in 1969), and

FTA-2 was utilized from 1961 to 1988 (USEPA, 1994b). FTA-2 was located at the north end
PFAS Preliminary Assessment Report

Former Crash Fire Station (Building 241)

Newington, New Hampshire

22

of the Pease flightline. AFFF was used at the FTA-2 to extinguish mixed waste oils, solvents,

and fuel training fires.

· North Apron: After the closure of FTA-2, the NHANG FD used the North Apron for testing

and calibration of the ARFF vehicle equipment.

· Fire Department Equipment Testing Area: The NHANG FD currently uses wooded area

south of Landfill 5 (FD Equipment Testing Area) for testing and calibration of the ARFF

vehicle equipment.

· KC-135 Accident Area: The Boeing KC-135 Stratotanker is a military aerial refueling aircraft.

In January 1990, a KC-135 burned and exploded during routine fuel cell maintenance. An

estimated 90,000 gallons of water and AFFF mixture were used to extinguish the fire.

· Hangar 253: Hangar 253 was equipped with an AFFF fire suppression system. The hangar

is located at the north end of the flightline, east of parking Row 3. AFFF was released during

the initial acceptance tests for the system conducted in 1992. The suppression systems

were designed to contain, store, and ultimately discharge the AFFF to the Pease Municipal

WWTP.

· Hangar 254: Hangar 254 was also equipped with an AFFF fire suppression system. The

hangar is located near Hangar 253 at the north end of the flightline, east of parking Row 3.

AFFF was also released during the initial acceptance tests for the system conducted in

1992. The suppression systems were designed to contain, store, and ultimately discharge

the AFFF to the Pease Municipal WWTP.

· Bulk Fuel Storage Area: The bulk fuel storage area contained an AFFF fire suppression

system. The system was installed in 1993 and decommissioned in 2012. The system was

never tested or used, nor was there an accidental release reported.

· Golf Course Maintenance Area: During the CERCLA PA, AFFF-labeled 55-gallon barrels

were identified in the golf course maintenance area. The maintenance area is located on

the north side of the golf course, west of the installation runway. The AFFF-labeled barrels,

at the time of the inspection, contained various constituents other than AFFF; however, it is

unclear if AFFF were stored or discharged in the area.

· Firing Range Area: An unknown quantity of AFFF was released north of the firing range

around 2006. The firing range was located south of the current FD Equipment Test Area.

AFFF released in this area could be collected by the brooks around Landfill 5, which

discharge into the Little Bay via Railway Ditch and Flagstone Brook.

· Supply Building 122: Site representatives said the Pease supply building (122) was used to

store AFFF. No further information was provided concerning the storage or handling of the

AFFF in this area.

· Pease International Tradeport WWTP: AFFF was collected and transported by the

installation sanitary sewer system from Hangars 253 and 254, and possibly the former crash

fire station, to the Pease International Tradeport WWTP. Additionally, PFAS could have

entered the soil and groundwater through cracks in the sanitary sewer system piping.

· Pease International Tradeport WWTP Outfall: AFFF collected by the installation sanitary

sewer system flowed to the municipal WWTP, where it would have been discharged into the

Piscataqua River through the outfall. This outfall also serves as the discharge point for the

city of Newington’s treated wastewater effluent.

· Flightline Storm Sewer System: The flightline storm sewers collected AFFF during the KC135 fire (see KC-135 Accident Area description above), transported the AFFF through the

storm sewer system, and discharged it into the McIntyre Brook through the main outfall

and/or the OWS.

· Flightline Storm Sewer Outfall: The PA indicates that a release of AFFF on the flightline

would have been collected and routed by the sewer system to the storm sewer outfall at the

McIntyre Brook.

· Current Crash Fire Station: The NHANG FD stores AFFF at the current crash fire station,

occupied beginning in 2006. AFFF is stored in two 850-gallon mobile trailers.

· Site 8 Recharge Trenches: The Site 8 groundwater hydraulic containment and treatment

system was designed to remove organic and inorganic contaminants from the groundwater.

Historically, the treatment facility was not designed to remove PFAS. Therefore,

groundwater containing PFAS extracted by the treatment system could have been reinjected into the aquifer via the recharge trench(s) that are located north of the flightline.

· Zone 3 Recharge Trench: The Zone 3 groundwater hydraulic containment and treatment

system was designed to remove contaminants from groundwater and discharge (in part) the

treated water via subsurface recharge. The treatment facility was not designed to handle

PFAS. Therefore, groundwater containing PFAS extracted by the treatment system could

be re-injected into the aquifer via the recharge trench that is located southwest of the

flightline.

· Golf Course Irrigation System: The Zone 3 groundwater hydraulic containment and

treatment system was designed to remove contaminants from groundwater and discharge

(in part) the treated water through surface application to the Pease golf course. The

treatment facility is not designed to handle PFAS. Therefore, any groundwater containing

PFAS extracted by the treatment system and used for irrigation purposes could be topically

applied to the ground throughout the golf course.

· Hodgson Brook: Groundwater from the 1992 aquifer test conducted on the Haven Well,

which is known to contain PFAS, was discharged into Hodgson Brook.

· Haven Well Treatment Plant Area: Groundwater from the 2002 safe yield test and

subsequent annual flow tests on the Haven Well, which is known to contain PFAS, was

discharged approximately 100 ft east of the Haven Well Treatment Plant and 475 ft up

gradient of the Harrison Well. Receiving waters for this discharge is Lower Grafton Ditch,

which flows into Hodgson Brook.

· IRP Site AB022 (former Burn Area 1) and IRP Site AB037 (former Burn Area 2): AFFF might

have been used as a fire suppressant at these two burn areas. Although definitive

documentation proving PFAS use was not available, PFAS and PFOA were detected in

groundwater in the area at concentrations exceeding the current USEPA HA and New

Hampshire MCLs and AGQS (Amec Foster Wheeler, 2017).

· McIntyre Brook, Peverly Brook, Knights Brook, Pickering Brook, and Flagstone: PFAS

releases from the above-described sources likely have entered the surrounding brooks via

surface water flow. The surface water runoff at the former Pease AFB is collected by a series

of manmade ditches, storm sewers, and drainage swales, some of which discharge to these

brooks.

Two of the PFAS release areas described above (the FTA-2 and Site 8 recharge trenches) were

subsequently investigated by the USAF in the Site 8 Investigation Report (Amec Foster Wheeler,
PFAS Preliminary Assessment Report

Former Crash Fire Station (Building 241)

Newington, New Hampshire

24

2016). The remaining PFAS release areas were investigated by the USAF in the Basewide SI for

PFAS (Amec Foster Wheeler, 2017). In June 2018, an Action Memorandum was prepared to

document the approval and decision by the USAF to conduct an Emergency Removal Action

(ERA) in response to the presence of PFOA and PFOS in private drinking water wells in

Newington, New Hampshire and surrounding areas of the former Pease AFB (USAF, 2018).

The USAF is continuing to address PFAS at the former Pease AFB in accordance with USEPA

Administrative Order SDWA-01-2015-0061. An AIMS is currently being implemented to treat

groundwater in the vicinity of the airfield. Additionally, a groundwater extraction and treatment

system was installed at Site 8 as an interim action to address PFOS and PFOA (Amec Foster

Wheeler, 2018).

6. Preliminary Conceptual Site Model

Based on the PA findings from interviews with Pease ANGB personnel, review of EDR reports,

and review of historic documents, known AFFF releases occurred at the former Crash Fire Station

during use by the USAF at the former Pease AFB and later during use by the NHANG FD at the

Pease ANGB. No releases have occurred since the property was transferred to the NHARNG in

2013. Because no PFAS sources were identified to originate from the NHARNG activities at the

facility, preliminary conceptual site models (CSMs) were not developed as part of this PA.

However, because known releases of AFFF have occurred at the former Crash Fire Station

historically, there is a potential for exposure to PFAS contamination in surface soil to site workers,

construction workers, and trespassers via ingestion and inhalation of dust; subsurface soil to 

construction workers via ingestion; surface water and sediment to nearby offsite receptors via

ingestion; and groundwater to construction workers and nearby offsite receptors via ingestion.

Potential offsite receptors include nearby residents and recreational users of the Great Bay and

Piscataqua River. 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.

To address the known releases of AFFF, ongoing PFAS response activities are being conducted

by the USAF at the former Pease AFB, including the former Crash Fire Station.

7. Conclusions

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

storage, and potential release of AFFF and other PFAS-related activities at the former Crash Fire 

Station (former Building 241). The PA findings are based on the information presented in 

Appendix A and Appendix B.

Findings

Known AFFF releases were identified (Table 7-1) at the former Crash Fire Station during use by 

the USAF at the former Pease AFB and later by the NHANG as the NHANG FD (Figure 7-1). No 

releases have occurred since the property was transferred to the NHARNG in 2013.

NHANG (Pease ANGB) ~1974 - 2006

Based on known AFFF releases at the former Crash Fire Station, there is potential for exposure 

to PFAS contamination in media at or near the facility.

Uncertainty

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, 

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 predominantly based on the information provided during interviews 

with personnel who had direct knowledge of PFAS use at the facility. Sometimes the provided 

information was vague. 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. 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, 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 the PA.

Area of Interest Source of Uncertainty

Former Crash Fire Station

No documentation of procurements records were kept for AFFF at

the former Crash Fire Station. Although 3% AFFF was always used,

the type and quantities are not documented.

Potential Future Action

Based on the PA findings from interviews with Pease ANGB personnel, review of EDR reports, 

and review of historic documents, known AFFF releases have occurred at the former Crash Fire 

Station.

The releases to soil and groundwater at the former Crash Fire Station were evaluated by the 

USAF as part of a basewide PA and SI for the former Pease AFB. At the time of this PA, the USAF 

has taken the lead in continuing to address PFAS at the former Crash Fire Station as part of the 

ongoing PFAS response activities at the former Pease AFB, in accordance with USEPA 

Administrative Order SDWA-01-2015-0061. An Airfield Interim Mitigation System (AIMS) is 

currently being implemented in response to the Administrative Order to treat groundwater in the 

vicinity of the airfield, including the groundwater at the former Crash Fire Station.

AFFF was stored at the station from

1974 to 2006. Two ARFF vehicles

were housed at the station; AFFF was

transferred to vehicles there. Vehicles

were also washed with AFFF. No

AFFF was released purposely but

small leaks were noted by

interviewees.
