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 Santa Fe Army Aviation Support Facility

(AASF; also referred to as the “facility”) in Santa Fe, New Mexico, to identify areas of known or

suspected releases known as Areas of Interest (AOIs) and possible exposure pathways to

receptors. The 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 PA site visit on 01 October 2019 and completed visual site inspections at

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

disposed;

· Interviewed current AASF New Mexico ARNG (NMARNG) personnel during the site visit and

NMARNG 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.

During the PA, one AOI related to potential PFAS release was identified at Santa Fe AASF based

on PA data. The AOI is shown on Figure ES-1 and described in Table ES-1 below:

Table ES-1: AOIs at Santa Fe AASF

Area of Interest Name Used by Potential Release Dates

AOI Former Fire Truck Bay NMARNG Through the mid-2000s

One adjacent off-facility potential PFAS release area was identified that includes an emergency

response area from two plane crashes in 2018 and 2019. As a result of adjacent PFAS releases,

it is possible PFAS contamination exists in site media surrounding the AASF.

Potential PFAS releases may have occurred at Santa Fe AASF based on the storage and potential

use of AFFF at the facility. Based on the possible PFAS releases at the AOI, there is potential for

exposure to PFAS contamination in media at or near of the facility. The preliminary CSM for Santa

Fe AASF is shown on Figure ES-2.

Based on the United States (US) Environmental Protection Agency’s (USEPA’s) Unregulated

Contaminant Monitoring Rule 3 (UCMR3) data, it was indicated that no PFAS were detected in a

public water system above the USEPA lifetime Health Advisory (HA) within 20 miles of the facility.

The HA is 70 parts per trillion for PFOA and PFOS, individually or combined. PFAS analyses

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. 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. Data received from city of Santa Fe March 2020 groundwater data

indicates no detections of PFAS related chemicals in the public water supply region where the

AASF facility is located.

ARNG will evaluate the need for an SI at Santa Fe AASF based on the potential receptors, the

potential migration of PFAS contamination off the facility, and the availability of resources.

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 (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 facilities that

used per- and poly-fluoroalkyl substances (PFAS) (a suite of related chemicals), 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 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 70 parts per trillion for PFOA and

PFOS, individually or combined.

This document presents the findings of a PA for PFAS-containing materials at the Santa Fe Army

Aviation Support Facility (AASF; also referred to as the “facility”), Santa Fe, New Mexico, 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 fire training areas (FTAs) as well as other locations where PFAS

may have been released into the environment at the AASF. 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.

1.2 Preliminary Assessment Methods

The following tasks were performed as part 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 PA site visit on 01 October 2019 and completed visual site inspections

(VSIs) at locations where PFAS-containing materials were suspected of being stored, used,

or disposed;

1.4 Facility Location and Description

Santa Fe AASF is located within the incorporated limits of and approximately 10 miles southwest

of downtown Santa Fe, New Mexico. The 22-acre facility is located on the northwest corner of the

Santa Fe Regional Airport and is leased to the NMARNG by the City of Santa Fe. The land was

acquired in 1976, and the original facility was constructed in 1979. The original facility consisted

of an AASF building and hangar and a small parking apron for helicopters. In 2012, the site was

completely renovated with a new, larger AASF building constructed adjacent to the former AASF

building, and the former AASF building converted to the Santa Fe Readiness Center (Appendix

A).

The properties immediately surrounding the AASF are also owned by the City of Santa Fe, with

the Santa Fe Waste Water Treatment Center to the north, and the Santa Fe Regional Airport

immediately to the west, south, and east. (Figure 1-1).

1.5 Facility Environmental Setting

The AASF is approximately 6,330 feet above mean sea level. The facility is covered by the US

Geological Survey (USGS) Turquoise Hill 7.5-minute quadrangle topographic map (Appendix A).

The geographic coordinates for the center of the facility are 106°18'31.454"W; 35°37'27.146"N.

The facility is developed with two large buildings, 3 small structures, and a helicopter parking

apron. One building, built in 1979 and renovated in 2012, is the former AASF and the current

administration headquarters for the NMARNG Readiness Center. The second building is the

current AASF, which is comprised of a 75,000-sqaure-foot hangar/administration building. A

16,400-square-foot storage building; a guard house; fuel storage area; and a 455,000 square feet

of concrete air field paving also exist on the property (PCL, 2019).

1.5.1 Geology

Santa Fe, New Mexico is located on the east border of the Rio Grande trough, in the Española

Basin, within the Rio Grande Rift. The basin formed during 25 million years of plate tectonic stress

pulling the land apart and causing a vast expanse of land to subside. When these basins formed,

large amounts of sediment filled the basin from the ancient flow of the Rio Grande and from

volcanic eruptions. These sediments, which fill the basin, make up an aquifer system that

contains the primary source of water for most residents who live in the basin (Española Basin

Technical Advisory Group [EBTAG], n.d.).

The Española basin in north-central New Mexico comprises the central portion of the Rio Grande

rift, which formed in response to rifting as early as Oligocene epoch. There are four main

physiographic units associated with the Santa Fe area: a complex of metamorphic and igneous

rocks from the Pre-Cambrian encompassing the Sangre de Cristo mountains in the eastern area; 

sedimentary and volcanic rocks Neogene to Quaternary in age in the southwest (Grauch and

Hudson, 2007); basalt flows of Quaternary in the western Mesa; and basin fill sediments of the

Santa Fe group in the intervening piedmont (Neogene to Quaternary) (Spiegel & Baldwin, 1963; 

Grauch and Hudson, 2007).

Most of the area consists of piedmont slopes underlain by late Cenozoic basin-filling deposits

called the Santa Fe marls. These marls are composed of silty sandstones, sand, and gravel about

300 feet thick. This layer lies overtop of a bedrock floor that is made up of sedimentary and

igneous rocks (Figure 1-2) (Spiegel & Baldwin, 1963).

1.5.2 Hydrogeology

Primary aquifers in the Española Basin are contained within the Tertiary-Quaternary Santa Fe

Group. Basin-fill aquifers of the Santa Fe Group are the principal groundwater resource for the

cities of Santa Fe, Española, and six Pueblo nations. The Santa Fe Group thickens to the west

and north, ranging from approximately 250 feet thick south of Santa Fe to greater than 10,000

feet beneath the Pajarito Plateau west of Española (Land, 2016). The Tesuque Formation

comprises the principal aquifer within the Santa Fe Group and is in hydraulic communication with

aquifers within the overlying Ancha and Puye Formations. The highly heterogeneous and complex

nature of the Tesuque aquifer reflects its depositional environment of coalescing alluvial fans, a

heterogeneity that is compounded by discontinuities created by faulting. The Santa Fe Group

aquifers are in hydraulic communication with Precambrian rocks along the eastern margin of the

basin, where most of the recharge occurs. Paleozoic limestones underlying the basin-fill aquifers,

fractured Tertiary intrusive rocks, and Tertiary volcanics of the Jemez volcanic field also locally

produce water (Land, 2016).

Groundwater flow in the area generally flows west towards the Santa Fe River. Recharge within

the basin is assumed to occur primarily from the higher elevations with little or no recharge from

the lower elevations because of high evapotranspiration and low precipitation (Spiegel and

Baldwin, 1963). The city of Santa Fe’s drinking water comes from a nearly even split between

groundwater from the Buckman and City well fields, and surface water from the Santa Fe and Rio

Grande rivers. The City Well Field is mostly located in close proximity to the Santa Fe River and

consists of seven active wells located within the City limits of Santa Fe. The Buckman Well Field

consists of 13 wells located near the Rio Grande, approximately 15 miles northwest of Santa Fe

(City of Santa Fe Water Division, 2017, Appendix A).

The percentage of water from any one source changes from month to month and year to year

depending upon a number of factors including availability, status of infrastructure, water rights,

turbidity in the Rio Grande, customer use, and engineering improvements (City of Santa Fe,

2019).

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

(GIS) databases, wells were researched to a 4-mile radius of the facility. One on-site unused well

was identified and located at the AASF, which has been capped and is in progress of being

plugged. Formerly, the AASF was allowed 3-acre feet of water to be used to domestic services.

The location of this well on the facility is shown on Figure 1-2. The depth to groundwater on the

base is approximately 50 to 800 feet below ground surface (bgs) (NMOSE, 2010).

1.5.3 Hydrology

The AASF is relatively flat and surface water generally drains towards the southwest. No lakes,

ponds, retentions basins, or areas of standing water are located on or immediately adjacent to

the facility, however, the Santa Fe River cuts through undeveloped land approximately 0.5 miles

from the AASF. Water features near the facility are shown in Figure 1-3.

Santa Fe’s surface water comes from the Santa Fe River and San Juan-Chama Project water via

the Rio Grande, both of which are treated through conventional and advanced treatment

processes to meet current permit regulations. The City of Santa Fe has a license to store up to

3,985 acre feet (combined) of Santa Fe River water in McClure and Nichols Reservoirs. Both

municipal drinking water supply reservoirs are located east of Santa Fe (City of Santa Fe Water

Division, 2017).

Based on the USEPA Unregulated Contaminant Monitoring Rule 3 (UMCR3) data, it was indicated

that no PFAS were detected in a public water system above the HA within 20 miles of the facility

(USEPA, 2017). The HA is 70 parts per trillion for PFOA and PFOS, individually or combined.

PFAS analyses 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.

1.5.4 Current and Future Land Use

Presently, Santa Fe AASF resides on Santa Fe Regional Airport property. The facility is comprised

of one hangar, multiple administrative buildings, a paved parking area, a fueling station, and a

small paved parking area. The current land use is listed as I-1 Light Industrial. Future land use is

not anticipated to change (City of Santa Fe GIS, 2019).

1.5.5 Climate

Santa Fe is located in north central New Mexico at an elevation above 7000 feet (US Geological

Survey [USGS], 2018). January is the coldest month, with an average temperature of 30.5

degrees Fahrenheit (oF), while July is the hottest month, with an average temperature of 70.1 (oF)

(NOAA, 2019). Santa Fe receives an average of 14.2 inches of precipitation annually, with 5.85

inches falling during summer months (National Oceanic and Atmospheric Administration [NOAA],

2019). The city receives an annual snowfall amount of 23 inches per year (NOAA).

2. Fire Training Areas

No FTAs were identified during the PA. According to interviews conducted with facility personnel

and historical research, fire training unlikely occurred on site, and there are not personnel

professionally trained for fire emergencies at the facility. In the event of an emergency, 911 is

called and the Santa Fe Fire Department will respond. Any fire suppressant training was

classroom based or used soap. Personnel interviewed also stated that the Santa Fe Fire

Department at one point may have trained at the AASF, but it would have been done with soap

only and it is unknown when or how often this training would have happened if it did occur.

Interview records appear in Appendix B.

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. Three non-FTAs where

AFFF was or is currently being stored were identified during the PA (Appendix B). A description

of the non-FTAs is presented below, and the non-FTAs are shown on Figure 3-1. Interview

records with are provided in Appendix B, and photographs are provided in Appendix C.

3.1 Former AASF Building

The former AASF building, which is now the current NMARNG Readiness center, is located on

the western portion of the facility and formerly housed a single firetruck within a bay (Figure 3-1).

It is unknown for how long the firetruck was stored in this bay, but it was sold in 2005 to the Santa

Fe Fire Department. Personnel interviews confirmed that the firetruck stored AFFF foam, but it

was never used because nobody on-site was qualified to use it. There are no records or

recollection of the any use or spill of the AFFF stored on the firetruck; however, there is a

possibility that the firetruck stored may have leaked AFFF or had its AFFF tank flushed out during

maintenance. The building was renovated in 2012 and received a new roof, exterior wall openings

and finishes, interior walls, floor finishes, ceilings, and lighting. Mechanical, electrical, plumbing,

fire protection, telecommunication, and security systems were replaced as well. The current

NMARNG Readiness Center building does not currently house any materials containing AFFF.

Interview records and a site map with the former fire truck location noted by interviewees is

available in Appendix B.

3.2 Current AASF Building

The current AASF building, located on the eastern portion of the facility, was built in 2012. This

building features an AFFF fire suppression system in the hangar. Interviewees indicated that this

fire suppression system was tested when it was first installed in 2012. Personnel confirmed that

while the fire suppression system was tested, it was completely controlled and confined to the

hangar and drain system. The drains in the hangar of the current AASF building all travel towards

a switchbox in the drain system that is designed to flip on when it detects foam, then travels west

southwest to an oil/water separator before continuing to the wastewater treatment plant across

the street from the facility. While personnel believe that the switchbox may not have been

functioning properly at the time, they are confident that the foam was entirely confined to the

hangar and drains. The area where the fire suppression system was tested is shown on Figure

3-1. The tank for the fire suppression system features a bladder and shows no signs of leakage.

3.3 Flight Line and Paved Parking Apron

The flight line and paved parking apron at the facility currently stretch across the majority of the

facility and are directly adjacent to both the current and former AASF buildings. The area was

expanded and repaved in 2012 during the construction and renovation of the facility. Prior to the

2012 renovation, Tri-MaxTM 70/30 hand trucks were stored in various places around the flight line

and parking apron and were regularly serviced. According to personnel, the Tri-MaxTM hand trucks

were only used for 4 to 5 years in the mid-2000s and were turned in because they were too

expensive to maintain. There is no recollection or record of any training conducted with these

units or nozzle testing performed. Interviewees were unsure about when or where specifically the
PFAS Preliminary Assessment Report

Tri-MaxTM units were turned in, but they no longer exist at the facility and have since been replaced

with fire extinguishers that do not contain PFAS. The primary area where the hand trucks were

stored is presented in Figure 3-1.

4. Emergency Response Areas

No emergency response areas were identified within the boundaries of the AASF facility during

the PA through interviews, previous investigations, online research, and the EDRTM report

(Appendix A). Personnel interviewed during the PA site visit stated that no incidents that required

fire suppression have occurred on site (Appendix B), and the City of Santa Fe Fire Department

provides emergency response to Santa Fe AASF. Interviews were conducted with personnel

whose firsthand knowledge of events dates from 1999 through present. A data gap exists for

Santa Fe AASF information between 1979 and 1999 due to records not typically kept by the facility

or available during the PA on the use of PFAS in training, firefighting, other non-traditional

activities, or on its disposition. keeping and lack of personnel with direct recollection of events

during that timeframe.

5. Adjacent Sources

One off-facility site was identified as a possible PFAS source adjacent to Santa Fe AASF during

the PA and is discussed below. Figure 5-1 presents the location of the suspected adjacent PFAS

sources.

5.1 Santa Fe Regional Airport

The Santa Fe Regional Airport (SAF) is a public airport that opened in 1941 and covers 2,128

acres. SAF has three active asphalt runways (GCR, 2019). Interviews with NMARNG facility staff

and a historical records search provided little information regarding use of AFFF at Santa Fe

Regional Airport; however, the records search detailed two emergency incidents that happened

on or near the runway – one on 27 November 2018, and another on 8 April 2019. According to a

local news source, the first crash occurred when a single-engine Mooney M20 crashed just short

of the runway and burst into flames (Edge, 2018). The second crash happened several months

after, when a two-seater aircraft crashed and burst into flames at the airport on a secondary

runway just south of the AASF facility (Mullan, 2019). It is unknown if AFFF were used as part of

the emergency response to either of these incidents. This possible adjacent source is presented

on Figure 5-1.

6. Preliminary Conceptual Site Model

Based on the PA findings, one potential release area was identified at Santa Fe AASF as a result

of NMARNG actions and will be considered an AOI. The AOI location is shown on Figure 6-1.

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, 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 a negligible

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

continues to be the subject of PFAS toxicological study. Receptors for Santa Fe AASF include site

workers, construction workers, and trespassers. The CSM indicates which specific receptors

could potentially be exposed to PFAS.

6.1 AOI: Former Firetruck Bay, Flight Line and Parking Apron

The former firetruck bay existed in what is now the former AASF building. The former AASF

building, located on the western portion of the facility, had housed a single firetruck within a bay

(Figure 6-1). It is unknown how long the firetruck was stored for in this bay, but it was sold in 2005

to the Santa Fe Fire Department. Personnel interviews confirmed that the firetruck stored AFFF

foam, but it was never used because nobody on-site was qualified to use it. There are no records

or recollection of the AFFF stored on this firetruck being used or spilled. Interview records and a

site map with the former fire truck location noted by interviewees is available in Appendix B.

In 2012, the former AASF building, including the firetruck bay, was completely renovated and no

longer exists as an AASF building. It is unknown if any drains existed in the former firetruck bay,

and if they did, where those drains may have led. Personnel interviews and records research

indicate that the drains on site currently flow directly through an oil/water separator and then to

the city’s wastewater treatment plant across the street.

The AOI encompasses the building that is the former AASF. There is a possibility that the firetruck

stored inside the may have leaked AFFF or may have had its AFFF tank flushed out during

maintenance. If a release occurred, ground disturbing activities in this area could result in

construction worker, site worker, and trespasser exposure to suspected PFAS contamination via

inhalation of dust of ingestion of surface soil. A construction worker could also be exposed to

subsurface soil affected by AFFF. PFAS are water soluble and can migrate readily from soil to

groundwater or surface water via leaching and run-off. However, groundwater beneath the facility

ranges from 900 to 1200 feet bgs, and the city sources roughly half of its drinking water from both

the Santa Fe and Buckman Well Fields approximately 12 miles northwest and northeast of the

facility. Groundwater flows generally southwest and away from the well fields. There are no known

drinking water sources downgradient of the facility; therefore, groundwater does not appear to be

a likely exposure pathway. Due to the arid desert climate, the pathway for surface water is

considered incomplete; however, it is possible that historic deposition of AFFF could occur during

rain events carrying into nearby ditches or recessed areas off-site. Given the high rates of

evapotranspiration, any such event would result in a quick evaporation of water, leaving the AFFF

on the surface soil and possibly sediment. Thus, soil and sediment pathways to site worker,

construction worker, and trespasser receptors are potentially complete. The preliminary CSM for

the AOI is shown on Figure 6-2.

7. Conclusions

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

and storage of AFFF at Santa Fe AASF. The PA findings are based on in the information presented

in Appendix A, Appendix B, and Appendix C.

7.1 Findings

One AOI related to suspected PFAS release was identified at Santa Fe AASF during the PA

(Figure 7-1) and is described in Table 7-1 below:

Table 7-1: AOIs at Santa Fe AASF

Interest Name Used by Potential ReleaseDates Determination

AOI Former Fire

Truck Bay NMARNG Through the mid2000s

Suspected PFAS

release

An adjacent potential PFAS release area was identified within the vicinity of the NMARNG facility.

Santa Fe Regional Airport had two plane crashes on the runway in 2018 and 2019, though it is

unknown whether AFFF were used to respond to these situations.

Based on documented potential PFAS release at the AOI, there is potential for exposure to PFAS

contamination in media at or near the facility. The preliminary CSM for Santa Fe AASF is shown

on Figure 6-2, which presents the potential receptors and media impacted. A summary of PA

findings is presented in Figure 7-1.

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,

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, other non-traditional activities, or on its disposition. There is no historically

documented use of PFAS-containing materials at the Santa Fe AASF by NMARNG staff.

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. 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 AFFF were first used, and a reliance on personal recollection. Inaccuracies

may arise in suspected AFFF discharge locations, discharge dates, discharge volumes, and PFAS

concentration. 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 personnel were interviewed, multiple persons were interviewed

for the same suspected source area, and suspected source areas were visually inspected. Table

7-2 summarizes the uncertainties associated with the PA.

any leaks or spills occurred during this timeframe is unknown.

Flight Line and Parking

Apron

It is uncertain if any fire training or leaks using AFFF happened

historically on the flight line and parking apron and where/when

the TriMaxTM units were dispatched.

7.3 Potential Future Actions

Interviews with NMARNG facility staff indicate that past ARNG activities might have contributed

PFAS contamination to soil, surface water, or sediment at the facility or adjacent areas.

Records review and interviews with NMARNG facility staff indicate that current or former ARNG

activities may have resulted in PFAS releases at the AOI at Santa Fe AASF. PFAS have the

potential to be present in the soil and surface water pathways. Based on the preliminary CSM

developed for the AOI, there is potential for receptors to be exposed to PFAS contamination in

soil and sediment. 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.
