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 the Utah ARNG (UTARNG) Sustained Airborne

Training Facility (SATF; the “facility”) that is located at the Salt Lake City International Airport in

Salt Lake City, Utah to assess potential PFAS release areas and exposure pathways to receptors.

The performance of this PA included the following tasks:

· Reviewed available administrative record documents and Environmental Data Resources,

Inc. (EDR)TM report packages to obtain information relevant to potential PFAS releases, such

as: drinking water well locations, historical aerial photographs, Sanborn maps, and

environmental compliance actions in the area surrounding the facility; 

· Conducted a 1-day site visit on 18 July 2019 and completed visual site inspections at

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

disposed;

· Interviewed current SATF personnel during the site visit including the UTARNG Safety NonCommissioned Officer (NCO) /Hazardous Materials (HAZMAT) Training Manager, the

UTANRG Environmental Manager, the Base Civil Engineer, and the Det 4/Det 50

Commander;

· Identified an Area of Interest (AOI) 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 the AOI.

One AOI related to a potential PFAS release was identified at the SATF during the PA. The AOI

is shown on Figure ES-1 and described in Table ES-1 below:

Table ES-1: AOI at SATF

Area of Interest Name Used by Release Dates

AOI 1 Building 10 UTARNG 2014

Based on information obtained during the PA, there is potential for exposure to PFAS

contamination in surface and subsurface soil to construction workers via ingestion and inhalation; 

surface water to offsite residents via ingestion, and groundwater to all receptors via ingestion. The

preliminary CSM for the SATF is shown on Figure ES-2.

The PA identified two adjacent potential PFAS source areas: the Aircraft Rescue and Fire Fighting

(ARFF) Training Center and the Salt Lake City International Airport.

The ARFF is considered a potential adjacent PFAS source area due to its heavy use of aqueous

film forming foam (AFFF) from 1998-2018. The Salt Lake City International Airport is considered

a potential adjacent source area due to the use of AFFF to extinguish approximately 10

emergency incidents on the runways of the airport, and various system discharges at airport

hangars. These potential adjacent PFAS source areas are shown on Figure ES-1.

One public well and a number of stock watering, irrigation, domestic, and non-production

groundwater wells have been identified in the vicinity of the SATF. The third Unregulated

Contaminant Monitoring Rule (UCMR3) data were reviewed to identify nearby sites that exceed

US Environmental Protection Agency (USEPA) lifetime Health Advisory of 70 parts per trillion for

PFOA and PFOS, individually or combined; however, none were identified (USEPA, 2017). PFAS

analysis performed in 2016 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.

Notes:1. The resident receptor refers to an off-site resident.2. Current risk practice suggests the exposure pathway for dermal contact is 

insignificant compared to ingestion, but supporting data is sparse and continues to be studied. 3. Based on the topography and water bodies in the vicinity of the SATF, it is assumed groundwater moves from west to east or northeast, towards the Jordan River. The Jordan River is the main source of irrigation water for farms in the Jordan 

Valley; therefore, the exposure pathway for surface water to the off-facility resident 

receptor via ingestion is potentially complete.

1. Introduction

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 (US) 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 their facilities 

that used per- and poly-fluoroalkyl substances (PFAS) (a suite of related chemicals), primarily 

releases of aqueous film forming foam (AFFF) (used for safety mitigation and emergency 

response efforts) although other sources of PFAS 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 these PFAS 

compounds in the environment will vary. The regulatory framework at both federal and state levels 

continues to evolve. In May 2016, the US Environmental Protection Agency (USEPA) issued 

lifetime Drinking Water Health Advisories (HAs) of 70 parts per trillion (ppt) for individual and 

combined PFOA and PFOS in drinking water. 

This report presents findings of a PA for PFAS-containing materials at the Utah ARNG (UTARNG) 

Sustained Airborne Training Facility (SATF; the “facility”) at the Salt Lake City International Airport 

in Salt Lake City, Utah, 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 Part 300), and Army 

requirements and guidance. 

This PA documents the known fire training areas (FTAs) as well as additional locations where 

PFAS may have been released to the environment at the SATF. The term PFAS will be used 

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

PFOA, which are key components of AFFF.

Preliminary Assessment Methods

The performance of this PA included the following tasks: 

· Reviewed available administrative record documents and Environmental Data Resources, 

Inc. (EDR)TM report packages to obtain information relevant to potential PFAS releases, such 

as: drinking water well locations, historical aerial photographs, Sanborn maps, and 

environmental compliance actions in the area surrounding the facility;

· Conducted a 1-day site visit on 18 July 2019 and completed visual site inspections (VSIs) at 

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

disposed;

· Interviewed current SATF personnel during the site visit including the UTARNG Safety NonCommissioned Officer (NCO) /Hazardous Materials (HAZMAT) Training Manager, the

Facility Location and History

The SATF is located in Salt Lake County, approximately 6 miles west of Salt Lake City, Utah. The 

facility is situated southeast adjacent to the Salt Lake City International Airport, at geographic 

coordinates 40°47'03.1"N; 111°57'28.4"W, in Salt Lake City, Utah, 84116 (Figure 1-1). 

According to the knowledge of interviewees, the facility was first constructed in the 1940s and 

used as a US Army Air Force (USAAF) facility until circa 1980, when the Air National Guard 

acquired the facility and used it as their fire department. The building was used to store firetrucks 

and AFFF under the jurisdiction of the Air Force. In approximately 2013, the facility was leased to 

the Army and remodeled with the installation of a fire suppression system. The leasing 

documentation available in Appendix A describes the property leasing by Salt Lake City to the 

US Government for use of the Utah Air National Guard (UTANG), US Air Force, and Army Aviation 

flight activities. The lease term began on 1 January 1988 and extends until 30 September 2037.

The SATF building, also referred to as “Building 10”, is the location of Site 8, a remedial site 

managed by the Air National Guard as an operable unit. The site is the location of two former 

underground storage tanks containing aviation gasoline, jet fuel (JP-4), or diesel. The source of 

contamination at Site 8 is attributed to possible releases from an oil-water separator. Groundwater 

monitoring is currently ongoing at Site 8 following groundwater remediation activities performed 

during 2014, which consisted of subsurface injection to promote anaerobic reductive 

dechlorination of contaminants of concern (CH2M Hill, 2015).

Facility Environmental Setting

The SATF occupies approximately 1 acre which is composed entirely of impervious surfaces 

(concrete and asphalt). The areas surrounding the SATF are primarily Air National Guard, Air 

Force, and various facilities in support of the operations of the Salt Lake City International Airport 

to the west. The facility sits at an elevation of 4,221 feet above mean sea level, with a very slight 

topographic slope to the northeast. The Great Salt Lake is located approximately 11 miles west 

of the facility, and the foothills of the Wasatch mountains are located approximately 5.5 miles east 

of the facility. 

1.5.1 Soil

According to the US Department of Agriculture (USDA) soil map, the soils at the facility generally 

consist of “made land” (USDA, 2019). Because the facility was once inundated by Lake Bonneville 

during the Pleistocene epoch, the soils underlying any paved surface and imported fill would be 

silty clay loam, silt loam, and fine sandy loam. 

1.5.2 Geology

The SATF is located in the Basin and Range physiographic province. The province is generally 

composed of northerly-trending, fault-block ranges and intervening, drier basins (Woods et al., 

2001). The underlying geology is dominated by deltaic (silt, sand, and clay) and lake deposits. 

Geologic units are depicted on Figure 1-2. 

1.5.3 Hydrogeology

The Basin and Range physiographic province is internally drained by ephemeral streams. Based 

on a review of the topographic map, local groundwater flow in the vicinity and beneath the facility 

is generally expected to be towards the north and east. Groundwater features are presented on 

Figure 1-2. 

Groundwater beneath and in the vicinity of the SATF is not used as a drinking water source. More 

than 60% of Salt Lake City’s water originates in the mountain streams of the Wasatch Mountains, 

supplemented with deep wells throughout the Salt Lake Valley. An EDRTM report conducted a well 

search for a 1-mile radius surrounding the facility (Appendix A). Using additional online 

resources, such as state and local Geographic Information System databases, wells were 

researched to a 4-mile radius of the facility. The EDRTM database search returned one public well 

and a number of stock watering, irrigation, domestic, and non-production groundwater wells in 

the vicinity of the facility (Figure 1-2). The closest underground wells for domestic use are located 

approximately 0.5 miles east of the facility. Data regarding US Geological Survey (USGS) wells 

in the area recorded depth to groundwater exists less than 10 feet below ground surface (bgs) 

(Utah Division of Water Rights [UDWR], 2019). 

The third Unregulated Contaminant Monitoring Rule (UCMR3) data were reviewed to identify 

nearby sites that exceeded the HAs of 70 parts per trillion for PFOA and PFOS, individually or 

combined; however, none were identified (USEPA, 2017). PFAS analyses performed in 2016 had

Sustained Airborne Training Facility

Salt Lake City, Utah

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.

1.5.4 Hydrology

The facility is located within the Jordan Hydrologic Unit. The majority of groundwater recharge

most likely comes from mountain precipitation and surface waters. The nearest surface water to

the subject property is the Jordan River, located approximately 1.1 miles east of the subject

property, and which flows into the Great Salt Lake to the north. Stormwater is expected to flow

offsite to stormwater drains or runoff in a northeasterly direction down a moderate grade. Surface

water features are presented on Figure 1-3.

Based on a desktop review of the National Wetlands Inventory online mapping system

(http://wetlands.fws.gov/; see Appendix A), the facility does not contain any mapped wetlands or

surface waters; however, there are approximately 465 acres of wetlands west of the airport that

were created in the 1990s to compensate for natural wetlands impacted by runway construction

(Salt Lake City International Airport, 2019). Due to the close proximity to the wetlands, the depth

to groundwater at the facility is expected to be very close to the surface.

1.5.5 Climate

The facility is located in an area characterized by a dry, mid-latitude desert climate, which is

marked by hot summers and mild winters (Woods et al., 2001). The annual average high

temperature in Salt Lake City is 78.7 degrees Fahrenheit (°F), and the annual low temperature is

29.5 °F, with an annual average temperature of 52.7 °F. The average annual precipitation is 16.10

inches, with most of it falling during the spring (March-May); the driest month is July, with average

precipitation of 0.61 inches. The average annual snowfall is 56.2 inches (National Oceanic and

Atmospheric Administration [NOAA], 2020).

1.5.6 Current and Future Land Use

The facility currently operates as a UTARNG Sustained Airborne Training Facility and is

comprised of a hangar, maintenance and storage areas, and an administrative office area.

Reasonably anticipated future land use is not expected to change significantly from the current

land use described above.

2. Fire Training Areas

UTARNG personnel confirmed there have been no fire training activities with AFFF at the facility

since at least 2013, when the ARNG first occupied the facility. Interviewees had knowledge of

operations dating back to 2013.

One FTA used by all airport units (including the UTARNG) exists within the vicinity of the UTARNG

property and is discussed in Section 5.

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. One non-FTA where AFFF 

could have been potentially stored and/or released was investigated during the PA, as described 

below and shown on Figure 3-1. 

Building 10

Building 10 was used as the UTANG fire station since the 1940s until approximately 2009. During 

the time this building was being used as a fire station, AFFF for the fire engines was stored onsite 

in 55-gallon drums and a 1,000-gallon trailer. Fire truck washing was also performed at the site. 

A building floor drain system captured liquids and transported the to the municipal sewer system 

(CH2M Hill, 2015).

A fire suppression system was installed at the facility when it was renovated circa 2014, and one 

full scale discharge test was conducted at installation. After the test, the foam was reportedly 

washed down the trench drains in the building, which flow to the oil/water separator before 

discharging to the municipal sewer system. 

The sanitary sewer system is serviced by the Salt Lake City Public Utilities Department. 

Wastewater is conveyed to the Salt Lake City Water Reclamation Facility, which provides 

secondary wastewater treatment, and discharges to Farmington Bay. 

During the renovation of the building, the sewage pipes were accidentally hooked to the oil/water 

separator and were replumbed circa 2015. During the replumbing activities, a break in the pipe 

was discovered. It is unknown if the break in the pipe were already existing or a result of the 

replumbing activities. The oil/water separator was reportedly damaged, and a bladder was 

inserted. During the system test, the drains were hooked to the oil/water separator; it is unknown 

if the discharge path of the foam were affected by the break in the pipe. 

One AFFF tank containing 55 gallons of Jet-X 2% high expansion foam concentrate was observed 

in the building’s mechanical room. Corroded concrete observed below the tank faucet indicated 

a slow leak coming from the tank. There were no signs that the leak had ever flowed farther than 

the immediate vicinity of the concrete directly below the tank, and therefore, there is no suspected 

release to soil, groundwater, or to drains leading to the sanitary sewer system.

5. Adjacent Off-Facility Sources

Two potential off-facility sources of PFAS adjacent to the facility were identified during the PA 

through interviews. A description of each potential adjacent source identified during the PA 

interviews is presented below, and the sources are shown on Figure 5-1. 

Aircraft Rescue and Fire Fighting Training Center 

The Aircraft Rescue and Fire Fighting (ARFF) Training Center is located approximately 2 miles 

northwest of the facility, at the Salt Lake City International Airport. The ARFF training center 

operated as an international fire-fighting training center from 1997-2018. The ARFF training center 

has a replica aircraft and burn pit where firefighters can train for fire emergencies. Firefighters at 

Fire Station 11 stated that various types and quantities of AFFF were used in this location on a 

daily basis. All firetruck and hose cleaning after the use of AFFF was conducted at the ARFF. 

Approximate geographic coordinates for fire training activities (based on description) are 

40°48'21"N; 111°59'18"W.

Salt Lake City International Airport 

Fire Station 11 provides fire support for the Salt Lake City International Airport and surrounding 

areas. Station 11 firefighters stated that in the last ten years, there have been less than ten 

emergency incidents that required the use of fire-fighting foam on the runways of the Salt Lake 

City International Airport. These firefighters also reported knowledge of two to three foam system 

discharges at the Delta Hangar in the last ten years. The firefighters and airport personnel both 

stated that all foam training and equipment cleanup took place at the ARFF, and that only water 

was deployed in the fire stations. 

Since the exact location of the emergency incidents and system discharges at the Salt Lake City 

International Airport are unknown, the entire airport is considered a potential adjacent source. 

Former Fire Training Areas

Three former fire training areas were investigated during a Site Inspection of AFFF conducted by 

the Utah Air National Guard in 2018 as listed below. 

· Area 1 - Former FTA-1 (Site 4): Located 0.45 miles northeast of the SATF at approximate 

geographic coordinates 40°47'26.3"N 111°57'15.3"W. Currently a paved parking lot used 

for recreational vehicle storage. Used for annual fire training exercises from 1947 to 1972. 

· Area 2 - Former FTA-2 (Site 5): Located 0.54 miles northeast of the SATF at approximate 

geographic coordinates 40°47'31.3"N 111°57'14.9"W. Currently a paved parking area for 

heavy machinery. Used two or three times for firefighting training between 1973 and 1975.

· Area 3 - Former FTA (AT016): Located 0.7 miles northeast of the SATF at approximate 

geographic coordinates 40°47'39.6"N 111°57'18.8"W. Currently an open area with low 

vegetation. Used for annual fire training from 1978 to approximately 1983.

These three areas were selected for SI based on potential or known use of AFFF during training 

activities; however, quantities of AFFF discharged were unknown. All three areas were found to 

have a potentially complete groundwater pathway for human digestion. An expanded SI was 

recommended for all three areas to determine whether groundwater impacted with PFOA/PFOS 

from previous on-base fire-fighting activities is migrating off base and presents a possible threat

6. Preliminary Conceptual Site Model

Based on the PA findings, there was one fire suppression system test at the facility with a 

confirmed discharge of AFFF to the trench drains in the building. The trench drains discharge to 

the oil/water separator, which was subsequently found to be damaged. It is unknown if the piping 

were damaged at the time of the AFFF release. As such, the soil under the SATF building has 

been determined an AOI and a possible PFAS source area. The AOI and preliminary CSM for the 

AOI are shown on Figures 6-1 and 6-2, respectively, and are summarized below.

The following sections describe the CSM components and the specific preliminary CSM 

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

complete exposure pathway: (1) source, (2) pathway, (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 studies (National Ground Water Association, 

2018). Receptors for the SATF include site workers, construction workers, residents, recreational 

users, and trespassers. The preliminary CSM for the AOI indicates which specific receptors could 

potentially be exposed to PFAS. 

AOI 1: Building 10

AOI 1 comprises the footprint of Building 10. The UTANG used the building as a fire station since 

the 1940s until 2009. The fire station had stored AFFF and AFFF-capable trucks that may have 

resulted in releases to the ground surface or municipal sewer system.

Since the UTARNG has occupied the building, there has been one known discharge of AFFF. The 

discharge of AFFF in the hangar area during the fire suppression system test in 2014 may have 

resulted in a release to a potentially broken pipe and subsequently, directly into the subsurface. 

PFAS are water soluble and can migrate readily from soil to groundwater or surface water via 

leaching and run-off. If PFAS releases to the subsurface soil occurred, it is possible that PFAS 

have migrated from subsurface soil at AOI 1 to groundwater and waters in the Jordan River, and 

therefore, the exposure pathway for groundwater to the off-facility resident receptor is potentially 

complete. Based on the topography and water bodies in the vicinity of the SATF, it is assumed 

groundwater moves from west to east or northeast, towards the Jordan River. The Jordan River 

is the main source of irrigation water for farms in the Jordan Valley; therefore, the exposure 

pathway for surface water to the off-facility resident receptor via ingestion is potentially complete. 

Ground-disturbing activities to subsurface soil could present another potentially complete 

exposure pathway to construction workers via ingestion of subsurface soil. There is no exposed 

surface soil present at the facility. The preliminary CSM for AOI 1 is shown on Figure 6-2.

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 the SATF. The PA findings are based on 

the information presented in Appendix A and Appendix B.

Findings

One AOI related to a potential PFAS release was identified (Table 7-1) at the SATF during the PA 

(Figure 7-1). 

Table 7-1: AOI at SATF

Area of Interest Name Used by Release Dates

AOI 1 Building 10 UTARNG 2014

Based on information obtained during the PA at this AOI, there is potential for exposure to PFAS 

contamination in subsurface soil to construction workers via ingestion and inhalation; surface 

water to offsite residents via ingestion, and groundwater to all receptors via ingestion. There were 

no suspected PFAS releases to the environment by the UTARNG outside the SATF building. 

Adjacent potential PFAS release areas were identified within the vicinity of the SATF. The ARFF 

is considered a potential adjacent PFAS source area due to its heavy use of AFFF from 1998-

2018. The Salt Lake City International Airport is considered a potential adjacent source area due 

to the use of AFFF to extinguish approximately ten emergency incidents on the runways of the 

airport and various system discharges at airport hangars. These potential adjacent PFAS source 

areas are shown on Figure 7-1. 

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. Records 

were not typically kept by the ARNG on the use of PFAS in emergency response or by non-ARNG 

units during training events at ARNG facilities. 

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

environmental reports, EDRsTM, observations made during the VSI, 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. 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 or its surrounding areas. Sometime, 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 at adjacent sources 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:

Table 7-2: Uncertainties within the PA

Location Source of Uncertainty

SATF (the Facility)

Foam was discharged down the building drains 

which flow to the oil/water separator. It is unknown if 

the discharge path of the foam were affected by a 

break in the pipe found during subsequent 

replumbing activities. The location was also 

previously used by the Air Force as a fire station. It 

is likely that AFFF was used and/or stored on site. 

The type, volume, and concentration of AFFF used 

or stored at the facility during Air Force possession 

are unknown. It is also unknown if equipment testing, 

nozzle testing, equipment washing, and line purging 

occurred at the facility.

It is unknown if AFFF were stored or discharged 

onsite prior to 1980 when the building was used as 

USAAF facility.

The building operated as an Air Force fire station 

circa 1980 until 2013. It is unknown if AFFF was 

discharged onsite. 

Aircraft Rescue and Fire Fighting 

Training Center – off facility

The type, volume, and concentration of AFFF used 

to extinguish the training fires are unknown. 

Salt Lake City International Airport 

(Various Runway Crashes) – off 

facility

The exact location of the various runway crashes at 

the Salt Lake City Airport since the 1940s is 

unknown. The type, volume, and concentration of 

AFFF used to extinguish the fires are unknown. 

Former Fire Training Areas – off 

facility

It is unknown if groundwater impacted with 

PFOA/PFOS from previous on-base fire-fighting 

activities is migrating off base and presents a 

possible threat to human health via ingestion of 

contaminated drinking water.

Potential Future Action

Interviews and records (covering 1994 to present) indicate that current or former ARNG activities 

may have resulted in a potential PFAS release at the AOI identified during the PA. Based on the 

preliminary CSM developed for the AOI, there is potential for receptors to be exposed to PFAS 

contamination in soil, surface water, sediment, and groundwater at the AOIs. Table 7-3

summarizes the rationale used to determine if the AOI should be considered for further 

investigation under the CERCLA process and undergo an SI.

Army did not control building prior to five years ago. Fire fighting efforts at this facility were done by the

air force.

Building was remodeled 5 years ago when the army took possession of the facility. Groundwater samples

were taken at this time.

AFFF system was put in 5 years ago before the renovation; the building likely just had sprinklers before

that. Foam in hangar is 5 years old, and has only been discharged during the full scale test at installation.

heard from a friend who filmed on his phone that it went well past 8 feet, the room filled up in

seconds. According to the mechanics consulted by during the interview, they just washed it

down the drain. No accidental discharges have occurred since then. No issues with bladder in tank or

system at all.

Drains go to oil/water separator. During the renovation, sewage was accidentally hooked to the oil/water

separator and had to be dug out approximately 4 years ago. There was a break in the pipe. The o/w

separator was damaged, so a bladder was inserted. The o/w separator goes to sewer system. They don’t

drain oil into the drain, it’s just for wash water. Sump has probably been pumped out a couple times. For

the first year and a half or 2 years, the sump pump kept tripping the breaker and there would be backup but

that hasn’t happened in a few years. O/w separator gets pumped out every 6 months or as needed; about

once a year.

Mobile extinguishers are owned by air force. Might be Halon. One in the hangar.

Since it was an old fire station it likely had chemicals here, to look into this.
