Executive Summary

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

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

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

(PFAS)-containing materials was completed for Camp Villere in Slidell, Louisiana, to assess

potential PFAS release areas and exposure pathways to receptors. Camp Villere is constructed

on a parcel of land owned in fee by the State of Louisiana.

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 site visit on 12 March 2019 and completed visual site inspections at locations

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

 Interviewed current and former Louisiana ARNG (LAARNG) Camp Villere personnel during

the site visit including Assistant Operations Manager (since 2012), LAARNG environmental

managers, and other operations staff. In addition, a senior staff member (since 2011) of the

St. Tammany Fire Protection District No. 1 (STFPD1) was interviewed.

 Identified Area(s) or Interest (AOIs) and developed a conceptual site model (CSM) to

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

groundwater, surface water, and sediment for each AOI.

One AOI related to a potential PFAS releases was identified at Camp Villere during the PA. The

AOI is shown on Figure ES-1 and described below:

Table ES-1: Camp Villere PA AOI

Area of Interest Name Used by Potential Release Date

AOI 1 Fire Training Areas

& AFFF Storage

St. Tammany Fire

Protection District No. 1

2008 - present

Based on documented releases of firefighting foam that potentially contains PFAS at this AOI,

there is potential for exposure to PFAS in media at or near the facility. Potential off-facility sources

of PFAS were identified. The preliminary CSM for Camp Villere is shown on Figure ES-2, which

presents the potential receptors and media impacted.

The LAARNG has not used, stored, trained with or released AFFF, not only on this particular

parcel of land, but throughout the entirety of Camp Villere. Potential PFAS releases are associated

with St. Tammany Fire Protection District No. 1 (STFPD1) use of the property. Although real

property accountability is be held by the Louisiana Department of Military Affairs, the property is

not utilized for federal training and therefore there is no federal responsibility for the site. With no

release due to federal training nor any federal interest in the real property, there is no authority to

carry the site into the SI phase.

Based on the USEPA Unregulated Contaminant Monitoring Rule 3 (UCMR3) data, it was indicated

that no PFAS were detected in a public water system above the USEPA Health Advisory (HA)

level within 20 miles of the facility. The HA is 70 parts per trillion for PFOS and PFOA, 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. 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.

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 will vary. The regulatory framework at both federal and state levels continues 

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

Advisory (HA) 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 PFOS and PFOA, 

individually or combined. 

This report presents the findings of a PA for PFAS-containing materials at Camp Villere in Slidell, 

Louisiana, 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 Camp Villere. 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 and other firefighting materials.

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 site visit on 12 March 2019 and completed visual site inspections (VSIs) at 

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

disposed;

· Interviewed current and former Louisiana ARNG (LAARNG) Camp Villere personnel during 

the site visit including the Assistant Operations Manager (since 2012), LAARNG 

environmental managers, and other operations staff. In addition, a senior staff member (since 

2011) of the St. Tammany Fire Protection District No. 1 (STFPD1) was interviewed.

· 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.

Facility Location and Description

Camp Villere (also referred to as the “facility”) encompasses approximately 1,440 acres in St. 

Tammany Parish, Louisiana (Figure 1-1). The facility is three miles northwest of Slidell, Louisiana, 

approximately 30 miles northeast of New Orleans, Louisiana, and approximately 6 miles north of 

Lake Pontchartrain. Other neighboring towns include Lacombe to the west and Pearl River to the 

northeast. Interstate 12 runs immediately south of the facility, and Interstate 59 lies approximately 

6 miles east. The following description of the facility and setting is primarily from the Phase II 

report (USACE, 2009).

Camp Villere was established in 1942 as a training site for Camp Plauche in New Orleans to 

provide additional training areas and firing ranges for the US Army. Throughout the 1940s, the 

facility was used as a rifle and pistol marksmanship training area for the soldiers at Camp Plauche 

and also as a training facility for reserve components of the services with their creation in the late 

1940s (Daigle, 1978; ERG and USACE, 2007). From the 1950s to the 1970s, the US Army 

continued to use Camp Villere for training and ammunition storage; however, it was also used by 

the LAARNG, with control of the facility passing to the LAARNG in the late 1950s (Casey, 1983; 

ERG and USACE, 2007; Teague et al., 1995). A quitclaim deed dated 8 April 1975 (included in 

Appendix A) transferred approximately 1,710 acres of the over 6,000-acre facility from federal to 

State control. Changes in operations and the termination of land use agreements have since 

reduced the facility to its current size and usage. By 2009, approximately 671 acres of the facility 

were operational, whereas the remaining 946 acres were non-operational. By 2014, real property 

changes to Camp Villere further decreased the facility area. Only a small portion of the facility,

fewer than 100 acres, remains classified as non-operational. Under a cooperative endeavor with 

the State executed on 26 March 1992, the STFPD1 is a LAARNG tenant occupying a 6-acre 

parcel of land on Camp Villere. The facility boundary was also modified to exclude a Veterans 

Affairs cemetery on the southern boundary of Camp Villere (USACE, 2009). LAARNG staff note 

transfer of the 75-acre cemetery parcel was completed in 2013. 

Facility Environmental Setting

Camp Villere is part of the East Gulf Coastal Plain physiographic region and is characterized as 

having gentle to flat topography. The elevation ranges from 15 feet to about 25 feet above mean 

sea level (amsl) on the facility. The highest elevations are in the northwest portion of the facility, 

and the lowest elevations are found in the south, generally more so in the southeast portion of 

the facility. Elevations at the firing ranges are approximately 20 feet amsl. Interstate 12, which is 

to the south of Camp Villere, can act like a dam during significant rain events and cause ponding 

along the southern border of the facility (ECC and Neel-Schaffer, Inc., 2003). 

1.5.1 Geology

Camp Villere is in the north shore area of the Lake Pontchartrain basin. This area is underlain by 

the Prairie Terrace geologic formation of the Pleistocene series within the Coastal Plain 

geomorphic province. The Prairie Terrace is the youngest terrace in southeast Louisiana and is 

the first well-defined, shore-parallel terrace below the Holocene deltaic plain (USGS, 2002). 

Deposits from this series range from 100 to 500 feet thick and were formed by sea level variations 

resulting from glacial and interglacial processes (ERG and USACE, 2007). Overall, the Prairie 

Terrace dips to the south-southwest, with a slope that varies from two to ten feet per mile (Saucier, 

1963). The lithology of the Prairie Terrace is difficult to generalize because sediments vary locally 

and regionally and have multiple depositional environments, such as fluvial, deltaic, and marine; 

however, generally, the formation consists of moderately to well-sorted, fine- to medium-grained 

sands with interbedded coarse sand, silt, and clay. The shallow terrace deposits underlying Camp 

Villere are composed primarily of clay with interbedded sand units. Alluvial deposits of the 

Holocene series found east and west of Camp Villere are associated with the streambeds of the 

Liberty Bayou and Bayou Bonfouca. The alluvial deposits consist of gray clay, silty clay, and some 

sand and gravel. Figure 1-2 shows the surficial geology at and near Camp Villere (NWRC, 1998).

1.5.2 Hydrogeology

Regional System

Camp Villere overlies the Southern Hills regional aquifer system, which is composed of the 

surficial fluvial formations along river valleys and the series of terrace deposits in the region. The 

upper part of these terrace deposits includes the Prairie Terrace formation. The Southern Hills 

regional aquifer system is a sole-source aquifer system that supplies water to all of southeastern 

Louisiana and is usually first encountered between 60 and 100 feet below ground surface (bgs). 

This complex system comprises three aquifer systems named by the United States Geological 

Survey (USGS) (in downward stratigraphic order): Chicot Equivalent Aquifers, Evangeline 

Equivalent Aquifers, and Jasper Equivalent Aquifers. 

These aquifer systems are broken down further into hydrogeological units. The Chicot Equivalent 

Aquifer system is composed of the Upland Terrace aquifer and the Upper Ponchatoula aquifer. 

The Evangeline Equivalent Aquifer system is composed of the Lower Ponchatoula aquifer, the 

Big Branch aquifer, the Kentwood aquifer, the Abita aquifer, the Covington aquifer, and the Slidell 

aquifer. The Jasper Equivalent Aquifer system is composed of the Tchefuncte aquifer, the 

Hammond aquifer, the Amite aquifer, and the Ramsey aquifer.

Regional groundwater flow in the Southern Hills aquifer system is to the south-southeast, with

main pumpage centers in Covington and Slidell (ERG and USACE, 2007; USGS, 2002; USGS 

and LA DOTD, 2002). The southern boundary of the recharge area for the Southern Hills aquifer

system is approximately 12 miles upgradient and north of Camp Villere (Lovelace, 2009).

Surficial Aquifer

The regional shallow surficial aquifer, overlying the Southern Hills regional aquifer system, is

recharged through precipitation infiltration via soils. This aquifer, comprised of the upper Prairie

Terrace formation, generally lies two feet or less below the loam soils at the ground surface.

Shallow groundwater flow direction mimics topography and generally flows to the south. At Camp

Villere, the surficial aquifer is encountered at slightly greater depths (approximately eight feet bgs)

and is locally semi-confined by a silty clay/clay unit that is laterally continuous across the facility.

However, a perched groundwater table, caused by the clay aquitard, is also present in parts of

the facility.

Groundwater flows south toward Liberty Bayou and Vincent Creek. Underlying confining clay

layers ranging from 60 to 100 feet thick separate the shallow groundwater from the deeper Chicot,

Evangeline, and Jasper Aquifer systems (Tomaszewski and Lovelace, 2007). Figure 1-2 outlines

groundwater pathways and potential groundwater receptor areas.

Drinking water for Camp Villere is obtained from the City of Slidell. Several public supply wells

are located downgradient within 1,600 feet of Camp Villere’s southern boundary. An EDRTM report

conducted a well search for a 1-mile radius surrounding the facility. Using additional online

resources, such as State and local GIS databases, wells were researched to a 4-mile radius of

the facility. One irrigation well is located approximately 900 feet downgradient of the southern

facility boundary. One water supply well, ST-776, is located on Camp Villere. While ST-776 is

currently not used, site personnel suggested it could be used in the future if municipal water supply

becomes unavailable.

Based on the USEPA Unregulated Contaminant Monitoring Rule 3 data, it was indicated that no

PFAS were detected in a public water system above the HA within 20 miles of the facility. The HA

is 70 parts per trillion for PFOS and PFOA, 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.

1.5.3 Hydrology

Camp Villere is approximately 6 miles north of Lake Pontchartrain and is within the lake’s

approximately 4,700-square-mile drainage basin (USGS, 2002). Two streams drain surface water

from Camp Villere. The first is Vincent Creek, which is a perennial stream approximately 10 to 15

feet wide and 3 to 4 feet deep that drains the eastern portion of the facility. Vincent Creek exits

the facility in the southeast corner and flows south-southeast to Bayou Bonfouca, which joins

Bayou Vincent. Bayou Bonfouca continues south and then southwest, through Big Branch Marsh,

and eventually to Lake Pontchartrain.

On the western side of the facility, the second stream, an unnamed intermittent stream, exits the

southwest corner of the facility and flows south, eventually discharging to Liberty Bayou. Liberty

Bayou joins Bayou Bonfouca approximately a half mile upstream from Lake Pontchartrain (US

Census Bureau, 2010a and 2010b). The northwest portion of the facility drains either to the

southwest or north toward off-facility detention ponds (MSE, 2001). The surface water pathways

can be seen on Figure 1-3.

The National Wetlands Inventory maps some isolated wetland areas on the facility, including

around the western edge of the Cantonment area (USFWS, 2019).

1.5.4 Climate

In general, Louisiana has a relatively constant, subtropical climate defined by long, hot, humid

summers and short, mild winters. Due to its location approximately 6 miles north of Lake

Pontchartrain in southeast Louisiana, conditions at Camp Villere are greatly influenced by its

proximity to the Gulf of Mexico. The proximity to the Gulf of Mexico increases precipitation and

humidity, stabilizes daily temperature variation, and makes the area prone to tropical storms and

hurricanes. Temperatures reach their average daily high in July and August, surpassing

90 degrees Fahrenheit (°F). January is the coolest month, with an average high daily temperature

of 61°F. Rainfall is fairly constant throughout the year; however, the highest precipitation totals 

generally occur in July and August, which have monthly averages of more than 6.5 inches of

rainfall. The average annual rainfall is over 60 inches (US Climate Data, 2019).

1.5.5 Current and Future Land Use

Camp Villere currently serves to provide resources and training for soldiers in support of

international, federal, and State missions, and it also has training facilities for additional

Department of Defense (DoD) personnel, including the US Marine Corps, the US Coast Guard,

the Naval Reserves, the Federal Bureau of Investigation, the Drug Enforcement Administration,

and local police and fire departments, including STFPD1 which, under a cooperative endeavor

with the State, is an LAARNG tenant occupying a 6-acre parcel of land on Camp Villere. Planned

land use changes were not noted by facility personnel during the site visit.

2. Fire Training Areas

FTAs are considered areas where deliberate discharge of AFFF or other firefighting materials is 

performed for purposes of training personnel. Two particular FTAs were identified at Camp Villere 

during the PA (Figure 2-1). The FTAs are currently and historically operated by STFPD1 and 

include a current fire training structure/former burn pit and a separate nozzle testing and live burn 

area. STFPD1 began fire training activities at Camp Villere in 1998, however, only information 

from 2008 – 2019 was available during the PA. 

Former Burn Pit FTA

The Former Burn Pit FTA is located in the western end of the Cantonment area (Figure 2-1). The 

geographic coordinates of the approximate center of the area are 30°18’47.5’’N; 89°49’03.2’’W. 

According to an interview with the senior staff member of the STFPD1, training activities by 

STFPD1 using “Chemguard SUPERTRAIN Training Foam (Chemguard Supertrain)” have been 

conducted multiple times per year from at least 2008 to present. The exact chemical makeup of 

Chemguard Supertrain is unknown. However, the safety data sheet (SDS; Appendix A) for the 

product lists a proprietary fluorosurfactant as a part of the mixture. Therefore, the Chemguard 

Supertrain foam is assumed to contain PFAS. It was reported that approximately a combined 60-

gallons per year of Chemguard Supertrain concentrate have been used between Former Burn Pit 

FTA and Nozzle Testing and Live Burn Area FTA, which is discussed below in Section 2.2.

The Former Burn Pit FTA is a former fire training pit, at which Chemguard Supertrain was released 

during live burns for STFPD1 training purposes. According to aerial imagery and the visual site 

inspection (VSI), a structure was built on top of the former training pit from 2015 – 2016. Firetrucks 

are washed at this location. However, a side container and a foam inductor are used during the 

training so that the firetruck tanks do not come into direct contact with the foam. Bare earth 

immediately surrounds all sides of this area, except for a concrete walkway off the northeast 

corner of the building. According to site personnel and field observations, an unlined drainage 

ditch runs to the west and south of the area, and eventually drains off-site to the east. This 

drainage ditch is completely vegetated with grass. No remediation activities have occurred at this 

FTA. 

Nozzle Testing and Live Burn Area FTA

The Nozzle Testing and Live Burn Area FTA is located in the western end of the Cantonment area 

(Figure 2-1). The geographic coordinates of the approximate center of the area are 30°18’48.8’’N; 

89°48’57.8’’W. According to an interview with the senior staff member of the STFPD1, nozzle 

testing and live burn activities have been conducted on multiple occasions by the STFPD1 using 

Chemguard Supertrain from at least 2008 to present. As noted above, a combined approximately 

60-gallons of the concentrate have been used per year between Former Burn Pit FTA and Nozzle 

Testing and Live Burn Area FTA. 

The small structure in this area was historically used for live burns, at which Chemguard 

Supertrain was released. Nozzle testing activities also occurred in this area. Bare earth with grass 

vegetation immediately surrounds all sides of this area. An unlined drainage ditch is located to 

the east of the area and runs to the south, eventually draining off-site. No remediation activities 

have occurred at this FTA.

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 

Chemguard Supertrain was stored was identified during the PA. A description of this non-FTA is 

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

AFFF Storage Container

The AFFF Storage Container (Figure 3-1) is located on the same STFPD1-occupied parcel as 

the Former Burn Pit FTA and Nozzle Testing and Live Burn Area FTA. The geographic coordinates 

at the approximate center of the building are 30°18’46.4’’N; 89°48’57.9’’W. Inside the AFFF 

storage container is a 250-gallon tank of Chemguard foam. During the site visit, approximately 

1/3 of the tank was full. A senior staff member at the STFPD1 reported that this tank is re-filled as 

needed when the supply is used for fire training activities. There is no inventory or documentation 

kept for foam on-site. 

The AFFF Storage Container is surrounded on all sides by bare earth. There was no evidence of 

staining or residue on the ground, and no evidence of corrosion or leaking inside the AFFF 

Storage Container.

5. Adjacent Sources

Slidell Municipal Airport

The Slidell Municipal Airport is located upgradient and adjacent to the facility’s northern boundary. 

No information was obtained during the PA about potential PFAS sources at the Slidell Municipal 

Airport. However, storage and use of AFFF is common at airports, therefore, the area is shown 

as a potential adjacent source on Figure 5-1.

6. Preliminary Conceptual Site Model

Based on the PA findings, one AOI was identified at Camp Villere: Fire Training Areas and AFFF 

Storage which are currently and historically operated by STFPD1. The AOI location is shown on 

Figure 6-1. The following sections describe the CSM components and the specific preliminary 

CSM developed for AOI 1. 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 is sparse and 

continues to be the subject of PFAS toxicological study (NGWA 2018). Receptors at Camp Villere 

include site workers, construction workers, residents, recreational users, and trespassers. The 

preliminary CSM for Camp Villere indicates which specific receptors could potentially be exposed 

to PFAS. 

AOI 1 – Fire Training Areas & AFFF Storage

AOI 1 includes FTAs and AFFF storage maintained and operated by STFPD1, which 

encompasses the Former Burn Pit FTA (Section 2.1), the Nozzle Testing and Live Burn Area FTA 

(Section 2.2) and the AFFF Storage Container (Section 3.1). Releases of approximately 60 

gallons per year of PFAS-containing Chemguard Supertrain foam to the soil by STFPD1 have 

occurred from at least 2008 to present. Additionally, there is the potential for PFAS to have been 

released during operation of the FTA from 1998 – 2008, but no information from that time period 

was gathered during the PA. No remediation activities have occurred at AOI 1. 

PFAS are water soluble and readily migrate from soil to groundwater. Since Chemguard 

Supertrain may contain PFAS, PFAS releases at AOI 1 have potentially occurred. PFAS may 

migrate from the surface soil to the shallow groundwater, which ranges in depth from 2.7 to 12.6 

feet bgs. Drinking water for Camp Villere is obtained from the City of Slidell. One public supply 

well is located approximately 700 feet downgradient of AOI 1. Four other public supply wells and 

one domestic well are located downgradient to cross-gradient of AOI 1 within 1,600 feet. One 

irrigation well is located approximately 1,200 feet downgradient of AOI 1. One water supply well, 

ST-776, is located on Camp Villere. While ST-776 is currently not used, site personnel suggested 

it could be used in the future if municipal water supply becomes unavailable. 

Ground-disturbing activities to surface soil at AOI 1 may result in site worker, construction worker, 

and trespasser exposure to potential PFAS contamination. Ground disturbing activities to 

subsurface soil could result in construction worker exposure. Therefore, the exposure pathways 

for inhalation of soil particles and ingestion of soil are potentially complete for these receptors. 

Based on the south to southeastern groundwater flow direction at Camp Villere, drinking water 

wells downgradient or cross-gradient may be impacted by Chemguard Supertrain releases at AOI 

1. Therefore, the exposure pathway for groundwater to all receptors is potentially complete.

Ephemeral drainage ditches flow around the AOI 1 area and eventually off-facility to the south;

therefore, surface water and sediment exposure pathways to all receptors are potentially

complete. 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 Chemguard Supertrain foam and other PFAS-related activities at Camp Villere. The PA

findings are based on the information presented in Appendix A and Appendix B.

Findings

One AOI related to potential PFAS release was identified at Camp Villere based on PA data. This

AOI is summarized in Table 7-1 below and shown on Figure 7-1:

Table 7-1: Camp Villere PA AOI

AOI 1 Fire Training Areas

& AFFF Storage

St. Tammany Fire

Protection District

No. 1

2008 – present

Potential off-facility sources of PFAS were identified during the PA.

Based on reported Chemguard Supertrain releases at this AOI, there is potential for exposure to

PFAS contamination in media at or near the facility. The preliminary CSM for Camp Villere is

shown on Figure 6-2, which presents the potential receptors and media impacted.

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

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 or conflicted with other sources. Gathered information has a degree of uncertainty due

to the absence of written documentation, the limited number of personnel with direct knowledge

due to staffing changes, the time passed since PFAS were first used (1969 to present), and a

reliance on personal recollection. Inaccuracies may arise in potential PFAS release locations,

dates of release, volume of releases, and the concentration of foam used. There is also a

possibility the PA has missed a source of PFAS, as the science of how PFAS may enter the

environment continually evolves.

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

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

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

inspected.

Table 7-2 summarizes the uncertainties associated with the PA:
PFAS Preliminary Assessment Report

Table 7-2: Uncertainties within the PA

Area of Interest Source of Uncertainty

AOI 1

The exact chemical makeup of the Chemguard Supertrain foam

used at Camp Villere is unknown. The SDS lists a proprietary

fluorosurfactant as an ingredient; Therefore, it is assumed that

the foam contains PFAS.

General

The history of STFPD1 activities at the installation prior to 2008

is unknown. The FTAs used by the STFPD1 have been in use

since 1998.

Potential Future Actions

Interviews and records (covering 2008 to present) indicate that current or former ARNG activities

have not resulted in potential PFAS releases at the AOI identified during the PA. STFPD1 activities

have resulted in potential PFAS releases at the AOI. Based on the preliminary CSMs developed

for this AOI, there is potential for receptors to be exposed to PFAS contamination in soil,

groundwater, surface water 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.

The LAARNG has not used, stored, trained with or released AFFF, not only on this particular

parcel of land, but throughout the entirety of Camp Villere. Potential PFAS releases are associated

with St. Tammany Fire Protection District No. 1 (STFPD1) use of the property. Although real

property accountability is be held by the Louisiana Department of Military Affairs, the property is

not utilized for federal training and therefore there is no federal responsibility for the site. With no

release due to federal training nor any federal interest in the real property, there is no authority to

carry the site into the SI phase.
