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 Beauregard Cantonment Area near

Pineville, Louisiana, 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 site visit on 24 January 2019 and completed visual site inspections at locations

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

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

during the site visit and LAARNG environmental managers and operations staff;

· Developed a preliminary conceptual site model (CSM) to outline the potential release and

pathway of PFAS for the Area(s) of Interest (AOIs) and the facility (Figure ES-1).

Three AOIs related to a potential PFAS release was identified at Camp Beauregard Cantonment

Area during the PA. The AOIs are shown on Figure ES-1 and described in Table ES-1 below:

Based on potential PFAS releases at three AOIs, there is potential for exposure to PFAS

contamination in media at or near the facility. The preliminary CSM for the Camp Beauregard

Cantonment Area, which presents the potential receptors and media impacted, is shown on

Figure ES-2. ARNG will evaluate the need for an SI at Camp Beauregard Cantonment Area

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

and the availability of resources.

Based on the US Environmental Protection Agency (USEPA) Unregulated Contaminant

Monitoring Rule 3 (UCMR3) data, no PFAS were detected in a public water system above the

USEPA Health Advisory (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. 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 polyfluoroalkyl substances (PFAS), primarily in the form of aqueous film 

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

possible. In addition, the ARNG is assessing businesses or operations adjacent to the ARNG 

facility (not under the control of ARNG) that could potentially be responsible for a PFAS release.

PFAS are classified as emerging environmental contaminants that are garnering increasing 

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

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

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

evolve. The US Environmental Protection Agency (USEPA) issued Drinking Water 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 the Camp Beauregard 

Cantonment Area (also referred to as the “facility”), near Pineville, 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 a known fire training area (FTA) as well as other locations where PFAS may 

have been released into the environment at the Cantonment Area. 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 site visit on 24 January 2019 and completed visual site inspections (VSIs) at 

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

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

during the site visit and LAARNG environmental managers and operations staff; and,

· Developed a preliminary conceptual site model (CSM) to outline the potential releases and 

pathways of PFAS for the Area(s) of Interest (AOIs) and the facility.

Facility Location and Description

Camp Beauregard is located in north central Louisiana, northeast of Pineville and Alexandria

(Figure 1-1). Camp Beauregard is approximately 13,618 acres and is separated into two distinct 

non-contiguous areas, the Training Site (locally known as Range Central) (12,889 acres) and the 

Cantonment Area (729 acres) (LAARNG, 2007). The Cantonment Area and most of the Training 

Site are in the Rapides Parish, although a portion of the Training Site extends into Grant Parish. 

This PA focuses on the Cantonment Area where the former Camp Beauregard Army Aviation 

Support Facility (AASF) helicopter airfield was located before it was moved to Esler Field in 2000-

2001. The Cantonment Area is bounded to the south and east by Esler Field Road (LA 116), by 

Monroe Highway (US Route 165) to the west, and by Flagon Bayou to the north.

Camp Beauregard was authorized by the War Department on 15 July 1917 for the training of 

troops for World War I, when it was determined that Camp Stafford was too small. After the war, 

the State of Louisiana acquired Camp Beauregard, and it became a training site for the National 

Guard. With the beginning of World War II in 1940, Camp Beauregard was federalized and used 

for the 1940 Louisiana Maneuvers and the Fifth Corps (LAARNG, 2007). Once World War II 

ended, Camp Beauregard came under control of the State of Louisiana for summer National 

Guard training. In 1973, Camp Beauregard was again used as an annual training facility (Malcolm 

Pirnie, Inc., 2003).

Facility Environmental Setting

Camp Beauregard is in the Upper West Gulf Coastal Plain physiographic region (USACE, 2014). 

The Cantonment Area topography ranges from around 100 to 160 feet above mean sea level (US 

Geological Survey [USGS], 2003; USGS, 2015) and is bisected by Flagon Bayou, which flows 

southeast across the Cantonment Area.

1.5.1 Geology

In general, the geology of central Louisiana is composed of marine sediments deposited by 

changing sea levels, and fluvial sediments deposited by the meandering Mississippi River system. 

These sediments dip less than 5 degrees toward the south-southeast, and their composition 

ranges from clays to sands (US Army Environmental Hygiene Agency [USAEHA], 1994). 

The geology of Camp Beauregard includes Quaternary surficial deposits overlying Oligocene to 

Miocene deposits. The surficial geology consists of the Bentley and Williana formations, which 

have two facies: a clayey and a sandy to gravelly facies (USAEHA, 1994). The Oligocene to 

Miocene deposits at Camp Beauregard consists of two formations, from oldest to youngest: the 

Catahoula Formation and the Fleming Formation, which comprises the Lena, Carnahan Bayou, 

Dough Hills, and Williamson Creek members. The Catahoula Formation contains thick beds of 

sand (fresh water bearing beds range from 10 to 230 feet thick) and thin layers of clay (US Army 

Center for Health Promotion and Preventive Medicine [USACHPPM], 2004). The Miocene-aged 

Fleming Formation is characterized by consolidated clays with discontinuous silts and sands 

(USAEHA, 1994).

At the Cantonment Area, the clayey facies of the Bentley and Williana formations are present in 

thicknesses ranging from 30 to over 100 feet. The clayey facies are underlain by the Williamson 

Creek, which is only present in the southernmost portion of the Cantonment Area, Dough Hills, 

Carnahan Bayou, and Lena members of the Flemings Formation and the Catahoula Formation. 

The geology at the Training Site differs slightly than that found at the Cantonment Area. The 

Williamson Creek and Dough Hills members of the Flemings Formation are absent at the Training 

Site. The Williamson Creek member terminates at the southern part of the Cantonment Area, and 

the Dough Hills member terminates just north/northeast of the Cantonment Area and is therefore 

not present at the Training Site. Second, the sandy to gravelly facies of the Bentley and Williana 

formations predominates in the Training Site (USAEHA, 1994). The geology of Camp Beauregard 

Cantonment Area is shown on Figure 1-2.

1.5.2 Soil

Soils at Camp Beauregard consist mostly of Quaternary-aged fine sandy loams and clay loams 

with marine or alluvial origins (USDA, 1980). Soils present at the Cantonment Area include Acadia 

silt loam, Cahaba fine sandy loam, Gore very fine sandy loams, Guyton complex, Kolin silt loam, 

Lucy loamy fine sand, Malbis fine sandy loam, Rexor-Nugent complex, and the Ruston fine sandy 

loam. The silty loams tend to have relatively low permeability, whereas the sandy loam has higher 

permeability. The pH of these soils range from 3.8-5.8 (US Department of Agriculture [USDA], 

2019).

1.5.3 Hydrogeology

The hydrogeology at Camp Beauregard is characterized as a multi-layered system composed of 

four aquifers: the Bentley and Williana, Williamson Creek, Carnahan Bayou, and Catahoula 

aquifers. The Jasper aquifer system comprises the Williamson Creek and Carnahan Bayou 

aquifers in Rapides Parish.
PFAS Preliminary Assessment Report

Camp Beauregard, Louisiana

Freshwater from the Bentley and Williana aquifer is sourced in the minor sandy lenses in the

clayey facies (USAEHA, 1994). Some geotechnical reports and Parish-wide aquifer studies do

not identify this aquifer, which suggests it is not a major source of freshwater in Rapides Parish.

Additionally, some sources incorrectly call this aquifer the Red River aquifer (USACHPPM, 2004),

which terminates at the Red River south-southwest of the facility.

The Williamson Creek aquifer is situated in the Williamson Creek member of the Fleming

Formation and is therefore only present in the southern portion of the Cantonment Area. The

aquifer sits within well-sorted, fine- to medium-grained sand interbedded with clay. Average

thickness of the sand beds is approximately 50 feet. The base of the aquifer ranges from 0 feet

below National Geodetic Vertical Datum of 1929 (NGVD 29) in northwestern Rapides Parish to

2,500 feet below NGVD 29 in the south (Griffith, 2009; Tomaszewski, 2009). Potentiometricsurface maps for the Williamson Creek aquifer show groundwater at the Cantonment Area flowing

southwest towards the Red River, directly between the cities of Alexandria and Pineville

(Tomaszewski, 2009). Approximately 270 wells were screened in the Williamson Creek aquifer;

193 of these wells are domestic, and 44 are public supply wells (Griffith, 2009). The confining unit

between the Williamson Creek and Carnahan Bayou aquifers is the Dough Hills member of the

Fleming Formation.

The Carnahan Bayou aquifer is the major aquifer at Camp Beauregard and is located within the

Carnahan Bayou member, which is composed of well-sorted, fine- to medium-grained sand

interbedded with clay, which are interpreted to have deltaic and marine origins. The sand beds

have an average thickness of approximately 38 feet. The base of the aquifer ranges from 0 feet

below NGVD 29 in northwestern Rapides Parish to 4,000 feet below NGVD 29 in the south

(Griffith, 2009; Tomaszewski, 2009). Potentiometric-surface maps for the Carnahan Bayou aquifer

show groundwater at the Cantonment area flowing southwest towards the Red River, directly

between the cities of Alexandria and Pineville (Tomaszewski, 2009). Approximately 210 wells are

screened in the Carnahan Bayou aquifer. Of these wells, 122 are domestic, and 71 are public

supply wells (Griffith, 2009).

The Lena member of the Fleming Formation is the confining unit between the Carnahan Bayou

aquifer and the underlying Catahoula Aquifer; however, at Camp Beauregard, the Catahoula

aquifer contains saltwater (USACHPPM, 2004).

Water to the facility and surrounding area is supplied by the Water Works District No. 3 of Rapides

Parish. The District distributes water sourced from seven groundwater wells (40 percent), with

two supply wells (No. 2 and No. 7) located within the Camp Beauregard Cantonment Area

(Figure 1-2). The remaining 60 percent of the District’s water is sourced from a surface water

intake on Big Creek in Grant Parish, approximately 8 miles north of the facility (French, 2020).

Several other wells were identified within a 1-mile radius of the Camp Beauregard Cantonment

area. The EDRTM report (Appendix A) identified 48 well records; however, several wells have

multiple records (e.g., one well may have a record for installation and a record for abandonment).

Using additional online resources, such as state and local GIS databases, wells were researched

to a 4-mile radius of the facility. Well depths ranged from 15 to 1180 feet below ground surface

(bgs). Several wells were noted as owned by the Louisiana National Guard (LNG), Camp

Beauregard, and the USGS; furthermore, 17 records noted plugged/abandoned or destroyed

wells (including several LNG wells). Eight wells were reported as monitoring wells installed to total

depths ranging from 15 to 80 feet bgs. Water levels listed for two monitoring wells (E17 and E18

owned by the Louisiana Air National Guard and located immediately north of the facility) were

reported as shallow as 3 feet bgs.

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 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,
PFAS Preliminary Assessment Report

Camp Beauregard, Louisiana

8

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

Camp Beauregard is situated in the watershed of Catahoula Lake, where surface water consists

of intermittent streams, open water bodies, and wetlands (LAARNG, 2007, USACE, 2014). The

Cantonment Area is in the Upper and Lower Flagon Bayou watersheds (Figure 1-3). The Flagon

Bayou flows southeast from northwest Rapides Parish through the Cantonment Area and,

eventually, northeast into Catahoula Lake. Local drainage features include a retention pond in the

northeastern portion of the Cantonment area, which overflows into Flagon Bayou.

1.5.5 Climate

Camp Beauregard has a sub-tropical climate influenced by its proximity to the Gulf of Mexico

(LAARNG, 2007). The average temperature at the facility is 65.85 degrees Fahrenheit (°F).

Seasonally, temperatures vary from a summer average monthly high of 94 °F to a winter average

monthly low of 37 °F. Average precipitation in Pineville is 57.48 inches (National Oceanic and

Atmospheric Administration [NOAA], 2019). The mean annual relative humidity is 74 percent

(LAARNG, 2007). The mean annual evaporation rate in central Louisiana is 45 inches (NOAA,

1982). Thunderstorm activity is most common during hurricane season (1 June–31 October),

when tropical storms and hurricanes regularly develop in the Gulf of Mexico. The tropical

disturbances cause high winds and excessive rainfall (LAARNG, 2007).

1.5.6 Current and Future Land Use

Camp Beauregard is primarily used for training LAARNG members but is also used for the

following (LAARNG, 2007):

· Military training for various reserve and active units;

· Training center for Special Operations Group of the United States Federal Marshall Service;

· Training for the Louisiana Youth Challenge Program;

· Branch headquarters for the Louisiana Office of Emergency Preparedness; and

· Recreational opportunities.

Adjacent land uses include residential, commercial/industrial, and institutional. Reasonably

anticipated future land uses are not expected to change from the current land uses. Access to the

facility is restricted and controlled by fencing and gates.

2. Fire Training Areas

One FTA was identified within the current facility during the PA interviews (Appendix B). This FTA 

is described below and shown in Figure 2-1. 

Wash Rack

LAARNG personnel believe the Wash Rack was constructed sometime after the AASF was 

moved to Esler Field in 2000-2001. AFFF was possibly discharged at the Wash Rack near 

Building 1338 during fire training activities. The Wash Rack is located on a concrete surface with 

a drain to an oil/water separator (OWS). The OWS drained to the retention pond until 2003, when 

it was closed (Section 3.1). Since 2003, wastewater from the Wash Rack is conveyed to and 

treated by the wastewater treatment plant adjacent to Pinecrest School. Photos of the concrete 

surface and drains leading to the OWS can be seen in Appendix C. There are no documented 

instances of AFFF usage. The approximate coordinates of the Wash Rack are 31°22’32.8”N; 

92°23’23.4”W.

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. Based on interviews 

conducted with facility personnel, with knowledge of the facility spanning from 1986 to current, 

two non-FTAs were identified during the PA where AFFF was stored or possibly released. 

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

Retention Pond

The Retention Pond is a former 33-acre large oxidation pond located on the eastern side of the 

Cantonment Area. In 2003, it was closed and converted into a natural wetlands area. Prior to 

2003, AFFF potentially released at the Wash Rack would have been rinsed and drained into OWS, 

which flowed to the Retention Pond. The approximate coordinates of the Retention Pond are 

31°22'45.2"N; 92°22'46.1"W.

Firehouse Building 327

Firehouse Building 327 was opened around 1995-1996 and remains active with multiple firetrucks 

and response vehicles. The firehouse is operated by the City of Pineville Fire Department.

During the VSI, it was observed that the Firehouse Building 327 currently stores Chemguard© six 

percent AFFF in five 5-gallon containers near the emergency response vehicles. Firetrucks 

carried 5-gallon containers up until around 2017. Spray tests were performed with these vehicles; 

no foam was used on site but was used in training off-post. The interviewee had no recollection 

of any AFFF leaks. The geographic coordinates for the Firehouse Building 327 are 31°22'13.90"N; 

92°24'10.89"W.

Interviewees also indicated that Tri-MaxTM extinguishers were housed at Camp Beauregard in an 

unknown location until 2000, when they were transferred to Esler Field Army Aviation Support 

Facility (Esler Field). Any fire extinguishers at the Cantonment Area may have been discharged 

prior to 1990 but have not been used since. It is unclear where the Tri-MaxTM extinguishers were 

located, but it is possible that they were stored at the Firehouse.

4. Emergency Response Areas

Based on interviews conducted with facility personnel, with knowledge of the facility spanning

from 1986 to current, no emergency response action using AFFF occurred at the Cantonment

Area of Camp Beauregard. No emergency response areas were identified within the current

facility during the PA through interviews or EDRTM Reports.

5. Adjacent Sources

Five adjacent off-site sources of potential PFAS, not under control of LAARNG were identified 

during the PA through interviews and data review. These off-facility sources include: Station 1, 35 

Purser St, Safety-Kleen Systems, Proctor and Gamble Manufacturing, and Esler Field. Figure 5-1

displays the adjacent sources described in this section.

Station 1

Station 1 is located approximately 3.5 miles southwest of the Cantonment Area in the City of 

Pineville. The Pineville Fire Department stored 5-gallon buckets of AFFF at Station 1. No further 

information was available regarding the use or disposal of the AFFF. Station 1 is hydrogeologically 

downgradient of the Cantonment Area.

35 Purser St

35 Purser St is located approximately 2.75 miles southwest of the Cantonment Area at 909 

College Dr, Pineville, LA. During fire training activities, the Pineville Fire Department discharged 

AFFF in unknown quantities at this location. 35 Purser St is hydrogeologically downgradient of 

the Cantonment Area.

Safety-Kleen Systems

Safety-Kleen Systems is located a mile west of the Cantonment Area. Safety-Kleen Systems is a 

used oil refiner that provides aqueous and solvent washers, equipment, and services. No 

information was available regarding the use of PFAS.

Proctor and Gamble Manufacturing

Proctor and Gamble Manufacturing is located a quarter mile southwest of the Cantonment Area. 

PFOA has been used by Proctor and Gamble Manufacturing to manufacture 

polytetrafluoroethylene in some of their products. No additional information was provided on their 

use or disposal of PFAS-containing materials.

Esler Field

Esler Field is located approximately 3.5 miles northeast of the Cantonment Area and is directly 

adjacent to (and south of) the Training Site. Esler Field is currently undergoing PA to evaluate 

their storage and use of PFAS-containing materials.

6. Preliminary Conceptual Site Model

Based on the PA findings, three AOIs were identified at the Cantonment Area. Locations of the 

AOIs are shown on Figure 6-1. The following sections describe the CSM 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.

Pathways

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

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

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

continue to be the subject of PFAS toxicological study (National Groundwater Association, 2018). 

Known and potential AFFF releases identified at the Cantonment Area occurred on both surface 

soil and paved surfaces. Releases to the paved surfaces could have migrated a short distance 

onto the surrounding surface soil. Ground-disturbing activities in these surface soil as well as 

beneath the pavement may result in potential exposure to surface soils via ingestion and 

inhalation of dust particles. AFFF releases to the paved surfaces could have infiltrated the 

subsurface via cracks in the pavement or joints between areas that are paved with different 

materials. Ground-disturbing activities may result in potential exposure to subsurface soils and 

groundwater via ingestion. 

PFAS are water soluble and can migrate readily from soil to groundwater via leaching. Drinking 

water at the Cantonment Area is sourced from two public supply wells within the facility boundary. 

Wells within approximately 2 miles downgradient of the facility include domestic and public supply 

wells and may result in potential exposure via ingestion of groundwater. 

Storm water runoff at the facility drains to Flagon Bayou. When Flagon Bayou rarely floods, storm 

water may enter the retention pond. Flagon Bayou flows off the facility to the northeast, into 

Catahoula Lake, and may result in potential exposure via ingestion of surface water and sediment. 

Receptors

Receptors at the Cantonment Area include site workers, construction workers, off-facility 

recreational users, and off-facility residents. These receptors, as they pertain to the facility, are 

described below:

· Site workers typically work at or use the site and may come into contact with the surface soils. 

Site workers may also come into contact with surface water in the retention areas.

· Construction workers are considered workers who represent a utility worker or other worker 

who would be exposed to surface and/or subsurface conditions through ground-disturbing 

activities. 

· Trespassers typically identify a person who has infrequent access to the site. 

· Off-facility recreational users could be exposed to sediment and surface water during 

recreational use.

· Off-facility residents identify receptors who occupy properties outside of the Cantonment Area. 

Off-facility residents may come into contact with groundwater using unregistered, private 

wells, domestic wells, or public supply wells. 

The preliminary CSM for the Cantonment Area indicates which specific receptors could potentially 

be exposed to PFAS. The preliminary CSM for AOI 1 is shown on Figure 6-2. The preliminary 

CSM for AOIs 2 and 3 is shown on Figure 6-3.

AOI 1 Retention Pond

AOI 1 includes the Retention Pond which was converted to a natural wetlands area in 2003. Prior 

to 2003, any AFFF potentially discharged at the Wash Rack entered the OWS and would have 

been conveyed to the Retention Pond. Any upgradient AFFF releases would flow towards the 

Retention Pond.

Releases at AOI 1 occurred to surface water. Surface water within the Retention Pond interacts 

with surface sediment and can leach into the underlying subsurface soil. PFAS are water soluble 

and can migrate readily into the shallow groundwater. Groundwater infiltrating into Flagon Bayou 

flows off the facility boundary toward Catahoula Lake. Potential PFAS exposure pathways 

resulting from releases at AOI 1 are described in Table 6-1.

AOI 2 Wash Rack

AOI 2 encompasses the Wash Rack. LAARNG personnel indicated that AFFF was possibly 

discharged at the Wash Rack. AFFF discharged at this location would have been rinsed and 

drained into the OWS, which may flow towards the Retention Pond. 

Releases of AFFF may have occurred on concrete and could have migrated off the concrete 

surface, thus resulting in PFAS contamination of the surface soil. AFFF may have also infiltrated 

subsurface soil via cracks in the pavement. PFAS are water soluble and can readily migrate from 

soil to groundwater. Overland flow would result in PFAS contamination in downgradient Retention 

Pond and Flagon Bayou. Flagon Bayou flows east, then northeast toward Catahoula Lake. 

Potential PFAS exposure pathways resulting from releases at AOI 1 are described in Table 6-2.

AOI 3 Firehouse Building 327

AOI 3 encompasses Firehouse Building 327. AFFF is currently stored in 5-gallon buckets within 

the Firehouse Building 327 near the emergency response vehicles. No known leaks have been 

reported. Fire extinguishers may have been discharged prior to 1990 but have not been used 

since. Additionally, firetrucks housed at Firehouse Building 327 carried 5-gallon containers of 

AFFF. 

Any releases would have occurred on paved areas, where they could migrate to surface soil. 

AFFF may have also infiltrated subsurface soil via cracks in pavement or joints between areas 

that are paved with different materials. PFAS are water soluble and can migrate readily from soil 

to groundwater via leaching. Surface water would flow downgradient toward the Retention Pond 

and Flagon Bayou. Potential PFAS exposure pathways resulting from releases at AOI 3 are 

described in Table 6-2 above.

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 Cantonment Area. The PA findings are 

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

Findings

Three AOIs related to potential PFAS releases were identified at Camp Beauregard Cantonment 

Area during the PA. A summary of the AOIs is shown in Table 7-1, and the location of the AOIs is 

shown on Figure 7-1.

Table 7-1: AOIs at Camp Beauregard

AOI 2 Wash Rack LAARNG Unknown

AOI 3 Firehouse Building 327 City of Pineville Fire 

Department

Mid 1990s - 

Current

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

contamination in media at or near the facility. The preliminary CSMs for the AOIs, which present 

the potential receptors and media impacted, are shown on Figures 6-2 and 6-3. 

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. 

The conclusions of this PA are predominantly based on the information provided during interviews 

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

information was vague. Gathered information has a degree of uncertainty due to the absence of 

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

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

personal recollection. Inaccuracies may arise in potential PFAS release locations, dates of 

release, volume of releases, and the concentration of AFFF used. There is also a possibility the 

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

continually evolves.

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

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

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

inspected. Table 7-2 summarizes the uncertainties associated with the PA.

Table 7-2: Uncertainties

Area of Interest Source of Uncertainty

AOI 2 Wash Rack It is unclear if AFFF was discharged at this location and the 

frequency at which this might have occurred.

AOI 3 Firehouse 

Building 327

Until 2017, fire trucks carried 5-gallon containers of AFFF. 

It is not known if these trucks were ever parked in another 

location other than the Firehouse for extended periods of 

time.

General

Tri-MaxTM units were located at Camp Beauregard prior to 

being moved to Esler Field in 2000. It is unclear where 

these units were stored while onsite.

Potential Future Actions

Interviews and records (spanning from 1986 to current) indicate that current or former ARNG 

activities may have resulted in potential PFAS releases at three AOIs identified during the PA 

(Table 7-1). Based on the preliminary CSM developed for the Site, there is a potential for 

receptors to be exposed to PFAS contamination in soil, groundwater, surface water, and sediment 

at these 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. 

ARNG will evaluate the need for an SI at Camp Beauregard Cantonment Area based on the 

potential receptors, the potential migration of PFAS contamination off the facility, and the 

availability of resources.

Hi ,

Thanks for calling today on behalf of Mr. and agreeing to research the total depths of the 2 supply wells at Esler

(#8 and #9) and the 2 at Camp Beauregard Cantonement Area (# 2 and #7). I am copying as he is working with me

on the Preliminary Assessment reports we are preparing for both of these facilities. I believe you also mentioned that

one of the Esler wells is being targeted for plug and abandonment due to ongoing water quality issues. Would that be

#9? If you have any additional information about when that is planned, please advise.

I had also asked Mr. about information regarding other wells WWD#3 uses for their water supply, specifically

locations and depths, particularly if they are within 4 miles of Esler or Beauregard facilities.

Lastly we would also be grateful if you are in a position to share results of any future PFAS sampling of one or more of

the wells you mentioned you may be conducting, so we can provide those results to our Army National Guard clients

accordingly.

Best regards,

********

Dear Mr. ,

Thank you for taking time to speak with me today. As I mentioned, AECOM is working for the Army National Guard at

Esler Field and Camp Beauregard. This confirms information you provided, specifically that your District obtains

approximately 60% of its source water from surface water drawn from Big Creek in Grant Parish; 40% from groundwater

including two wells at Camp Beauregard (#2 and #7) which require treatment to remove organic color. Two wells at Esler

Field (#8 and #9) are offline due to methane which is cost prohibitive to treat. However, well #8 is used to supply Esler

Field’s maintenance facility’s fire protection water storage tank.

I look forward to receiving any additional information you can provide about the depths of these wells; and,

location/depth of other wells used by WWD#3, at your earliest convenience.

I was able to speak with Mr. with the Buckeye Water District #50 regarding their wells, so I greatly

appreciate you directing me to them.

Best regards,
