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 Sparta Training Area (STA) (also referred to as

the “facility”) in Sparta, Illinois to assess potential PFAS release areas and exposure pathways to

receptors. STA is a state-owned property, and occupation of the property by the Illinois ARNG

(ILARNG) began in 1986. 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 27 August 2020 and completed visual site inspections at locations

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

· Interviewed current ILARNG personnel and the Sparta Fire Department Fire Chief during the

site visit.

No known or documented releases of PFAS to the environment were identified at the facility during

the preparation of this PA report. Two adjacent sources, the Sparta Fire Department and Sparta

Community Airport, were identified as potential PFAS release areas. Based on the inferred

groundwater flow direction, Sparta Community Airport may be potentially upgradient from the

facility, and Sparta Fire Department is cross-gradient to the facility (Figure ES-1).

Based on the United States Environmental Protection Agency (USEPA) Unregulated Contaminant

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

system above the USEPA’s lifetime 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. Evidence does not indicate that current or former ARNG activities having

contributed to PFAS contamination in soil, groundwater, surface water, or sediment at the facility

or adjacent areas. No Areas of Interest related to PFAS release were identified at STA based on

the PA findings.

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 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 a lifetime 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 Sparta Training 

Area (STA) (also referred to as the “facility”) in Sparta, Illinois, 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 locations where PFAS may have been released into the environment at 

the STA. 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 27 August 2020 and completed visual site inspections (VSIs) at

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

disposed; 

· Interviewed current Illinois ARNG (ILARNG) personnel and the Sparta Fire Department Fire

Chief during the site visit.

Facility Location and Description

STA occupies approximately 2,635 acres in Sparta, Randolph County, Illinois, and it is located 

approximately 45 miles southeast of St. Louis, Missouri and 25 miles southeast of Scott Air Force 

Base. The facility’s administrative buildings and parking lots are accessible along North Hillcrest 

Drive and Industrial Drive. Figure 1-1 illustrates the location of the STA. 

The facility was provided by the Peabody Coal Company to the Illinois Department of Military 

Affairs at no cost in 1986 and has been used by ILARNG since then for professional military 

training. Deed agreements and easements are included in Appendix A. 

Facility Environmental Setting

The facility is located in the Central Till Plains Section of the Central Lowland physiographic 

province. Sparta sits in Mount Vernon Hill Country, a smaller physiographic division of the Central 

Till Plains, which is characterized by level to low-relief topography sloping generally southwest 

toward the Mississippi River (Reinertsen et al., 1992). The Mount Vernon Hill Country area was 

moderately glaciated during the Pleistocene Epoch, leaving a relatively thin layer of glacial till 

covering the region. The topography of the region is primarily governed by pre-glacial features, 

though lowland areas are dominated by more recent alluvial and fluvial deposition (Reinertsen et 

al., 1992). Elevation on the STA ranges between approximately 436 to 525 feet above mean sea 

level.

The facility was established on a 2800-acre reclaimed strip mine that was used to produce coal

until 1992 (USACE, 2004; Illinois State Geological Survey [ISGS], 2010). Prior to mining, the area

was a natural prairie. The STA is sparsely developed and is characterized by three ecosystems:

riparian forest, upland plains, and lakes (USACE, 2004).

1.5.1 Geology

The City of Sparta, Illinois is located on the Sparta Shelf, a quasi-circular depositional region

situated between the Missouri Ozark mountains to the west and the present-day Illinois Basin to

the north and east (Reinertsen et al., 1992). Rocks of the Sparta Shelf are part of the uppermost

Illinois Basin, a broad depression that once extended across much of Illinois and surrounding

states; tectonic activity at the end of the Pennsylvanian period upilfted the Sparta Shelf, forming

a shallow depression that eventually proved rich in oil, gas, and coal. Most of the underlying rocks

at the facility are Pennsylvanian deposits dominated by shales and carbonates, with few

sandstones. The uppermost bedrock is composed of three major formations (in order of

deposition): the Tradewater, Carbondale, and Shelburn-Patoka formations. The earlier

Tradewater Formation is primarily made of coal, with minor units of limestone and shale. The

Carbondale Formation contains shale and coal units, with minor limestone. Finally, deposits of

the uppermost bedrock formation, the Shelburn-Patoka, are dominated by limestone and contains

minor coal and sandstone units (ISGS, 2005). These geologic units contain aquifers and are

presented on Figure 1-2.

Glaciers covered much of the Upper Midwest during the Pleistocene, leaving glacial landforms

across most of the state of Illinois. Glaciation likely removed most evidence of Tertiary deposition

in Illinois, though parts of southern Illinois contain Tertiary sediments (Reinertsen et al., 1992).

Due to long-term glaciation, the shallow subsurface geology near Sparta is covered by a relatively

thin layer of glacial sediments, approximately 5 feet thick (Reinertsen et al., 1992). Terrestrial

deposition is characteristic of Holocene sediments in this region and primarily occurs in and

around major river systems.

1.5.2 Hydrogeology

Regional groundwater flow in southern Illinois appears to generally follow surface water drainage

patterns. Shallow sand and gravel aquifers correlate to major fluvial systems in the region,

including the Mississippi, Illinois, Kaskaskia, Little Wabash, and Embarras Rivers, all of which flow

generally to the south. Shallow sand and gravel aquifers are present along extant river systems,

including the Kaskaskia River to the west of the facility. Potential shallow groundwater is present

less than 50 feet below ground surface (bgs) (ISGS, 2020). Major rock aquifers of the region

include those associated with Pennsylvanian shales and limestones, including the ShelburnPatoka, Carbondale, and Tradewater Formations and the Upper Pope Group. Groundwater is

present at varying depths in the area around the facility, including aquifers <300 feet bgs and

>500 feet bgs (ISGS, 2020). Based on topographic and hydrologic features, the inferred

groundwater flow direction is to the southwest. Groundwater features are present in Figure 1-2.

An EDRTM report conducted a well search for a 1-mile radius surrounding the facility (Appendix

A). Using additional online resources, such as state and local Geographic Information System

databases, wells were researched to a 4-mile radius of the facility. The STA is supplied by

municipal water, and there are no potable wells located on the facility. Several other/unknown

type wells are located on the facility and in the surrounding area. The USEPA Unregulated

Contaminant Monitoring Rule 3 (UCMR3) data indicate that PFOS/PFOA were not detected in a

public water system above the HA within a 20-mile radius 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

6

concentrations of PFAS were not detected during the UCMR3 but might be detected if analyzed

today.

1.5.3 Hydrology

The facility is located in the Plum Creek Watershed, which flows southwest along the northwest

facility boundary (Figure 1-3). Plum Creek is a tributary of the Kaskaskia River and flows to the

southwest, eventually draining into the Mississippi River approximately 16 miles to the southwest.

Three smaller streams and several small detention ponds are present within the facility, and two

off-facility ponds are located adjacent to the facility, one in the northwest and one to the southeast

of the facility.

Runoff potential in the facility area is moderate. The Natural Resources Conservation Service

(NCRS) classifies soils into four Hydrologic Soil groups based on runoff potential and infiltration

capacity, or transmissivity (United States Department of Agriculture [USDA], 2009). Group A soils

(sand-dominated) allow the least runoff and have the highest transmissivity, while Group D soils

(clay-dominated) cause the most runoff and have the lowest transmissivity. The soils of the STA

are primarily Group B and C, with moderately high runoff potential and moderate to somewhat

low transmissivity (ILARNG, 2011). Surface water features are presented in Figure 1-3.

1.5.4 Climate

The STA is in a humid subtropical climate zone characterized by long, warm summers and

relatively short, mild winters. Sparta sees an annual average precipitation of 44.9 inches, with

most rainfall occurring during the spring months (National Ocean and Atmospheric Administration

[NOAA], 2010). Summer temperatures peak in July, with an average high of 89 degrees

Fahrenheit (°F) and an average low of 71 °F. Winter temperatures are lowest in January, with an

average high of 40 °F and an average low of 24 °F. The Sparta area receives an average of 13

inches of snowfall annually (National Weather Service Forecast Office, 2020).

1.5.5 Current and Future Land Use

The facility was provided by the Peabody Coal Company to the Illinois Department of Military

Affairs at no cost in 1986 and has been used by ILARNG for professional military training. The

STA is mostly grass-covered, with some ponds and wooded areas. Development is primarily found

in the southeast part of the facility. The different organizational units at the STA include the Armory

and Firehouse, and areas adjacent to the facility are primarily residential and agricultural, with

some industrial land use in the surrounding region (ILARNG, 2011). Reasonably anticipated future

land use is not anticipated to change from the current land use.

2. Fire Training Areas

No FTAs where AFFF may have been potentially released were identified through record reviews

and interviews during the PA. ILARNG personnel stated during interviews that they train with

water only within the facility. Prescribed burn exercises are conducted annually every spring and

occur all over the training areas of the facility. The prescribed burns are extinguished with water

from the firetrucks, water tankers, and/or other equipment. Fire training is also conducted offfacility at the Scott Air Force Base and Marseilles Training Center, but foaming agents are never

used.

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. Two non-FTAs where AFFF 

was stored and/or potentially released were identified during the PA. A description of each nonFTA is presented below, and the non-FTAs are shown on Figure 3-1. 

Armory

The Armory is a 26,000-square foot building constructed in 1990. The kitchen is equipped with 

an Ansul R-102 wet chemical fire suppression system. The wet chemical agent used in the system 

is composed of a mixture of organic salts and reportedly does not contain PFAS. The data sheet 

for the fire suppression system is included in Appendix A. According to the interviewed ILARNG 

personnel, the fire suppression system has never been triggered and is not currently in use. Only 

portable ABC and wet chemical fire extinguishers (non-AFFF) are stored within the Armory. The 

Armory is not considered to be a potential release area of PFAS. 

Firehouse 

The Firehouse is northwest of the Armory, and construction was completed on 3 July 2008. The 

Firehouse is home to the 661st and 662nd Fire Fighting Teams (FFTs). There are two firetrucks 

and two water tankers stored within the Firehouse. The firetrucks each have two 60-gallon foam 

tanks and 1000-gallon water tanks, and the water tankers each have a 2500-gallon water tank. 

According to ILARNG personnel, the vehicles were most likely acquired in 2008, after the 

Firehouse was constructed. The interviewed ILARNG personnel has been with the FFTs since the 

two units were established in 2007. 

There has never been storage of AFFF at the facility; however, the firetrucks have a history of 

containing AFFF when deployed. In 2009, one firetruck was deployed to Scott Air Force Base to 

support an air show. The firetruck was filled with an unknown type of foam concentrate. The air 

show occurred without an emergency incident, and no foam was ever released through the fire 

hoses. The foam tank was drained and rinsed before the firetruck returned to the STA. In 2012 

and 2017/2018, the FFTs utilized two firetrucks during deployment to Afghanistan and Iraq, 

respectively. During the deployments, the firetrucks were filled with an unknown type of foam 

concentrate, but the foam was never utilized. The foam tanks were drained and rinsed prior to 

returning to the STA. 

During the VSI, trench drains were observed within the Firehouse. The drains lead to an oil-water 

separator before discharging into the sanitary sewer. The oil-water separator is located in the 

back of the Firehouse, where the fire hoses are washed and nozzle tested with water. Because 

AFFF has never been present within the Firehouse, the Firehouse is not considered to be a 

potential release area of PFAS.

4. Emergency Response Areas

Emergency responses to crashes sometimes require flame suppression, which may result in the 

release of PFAS to the environment in the form of AFFF. The Sparta Fire Department provides 

fire emergency and first responder services to the STA. One emergency response area was 

identified during the PA. A description of the emergency response area is presented below and 

shown on Figure 4-1.

Telephone Pole Fire

ILARNG personnel stated that during a prescribed burn exercise, there was a single incident in 

the 2000s where a telephone pole accidentally caught on fire. The Sparta Fire Department was 

called to help respond to the emergency. ILARNG personnel could not recall the exact 

extinguishing agent used by the Sparta Fire Department but believed that water was likely used. 

The interviewed Sparta Fire Department Fire Chief was not familiar with the incident but confirmed 

that based on the nature of the fire, water was likely used. The Sparta Fire Department only uses 

AFFF for large structural fires, car fires, and oil tanker fires. The telephone line has since been 

removed from the area, and based on aerial imagery, this removal occurred between 2016 and 

2017. The telephone pole fire is not considered to be a potential release area of PFAS.

5. Adjacent Sources

Two potential off-facility sources of PFAS adjacent to the STA, not under the control of the 

ILARNG, were identified during the PA. A description of each adjacent source is presented below, 

and the adjacent sources are shown on Figure 5-1.

Sparta Fire Department

The Sparta Fire Department is the local volunteer fire department with a fire station located 

approximately 1.7 miles southeast of the facility. The interviewed Sparta Fire Department Fire 

Chief stated that 3%-6% AFFF is stored within their fire station and in firetrucks. The Sparta Fire 

Department has used AFFF on structural fires, car fires, and oil tanker fires and perform annual 

training with AFFF outside the fire station. However, the Fire Chief maintains that AFFF has not 

been used for any emergency responses within the STA, including the telephone pole fire incident 

described in Section 4.1. The Sparta Fire Department’s fire station is considered to be a potential 

PFAS release area due to the storage and use of AFFF at the property. 

Sparta Community Airport

The Sparta Community Airport is located approximately 0.5 miles east of the facility. The airport 

is home to Arch Air Ambulance, which provides helicopter-based ambulance services, and Sparta 

Aero Services, Inc., a fixed-based operator (Sparta Community Airport, n.d.). An off-facility VSI 

was not conducted at the airport, and it is unknown if any fire training activities or AFFF releases 

have occurred. Airports have historically been sources of PFAS due to AFFF storage, mandated 

Federal Aviation Administration AFFF training on aircraft rescue and firefighting vehicles, and 

emergency responses requiring flame suppression; therefore, the Sparta Community Airport was 

identified as a potential PFAS release area.

6. Preliminary Conceptual Site Model

Based on the PA findings, no release areas were identified as AOIs; therefore, a preliminary 

conceptual site model (CSM) is not required for the facility. A CSM identifies three components

necessary for potentially complete exposure pathways: (1) source, (2) pathway, and (3) receptor.

If any of these elements are missing, the pathway is considered incomplete. Based on the findings

of this PA, there are no PFAS sources at the STA; thus, there is no complete exposure pathway 

to potential receptors from ARNG use of the facility.

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 STA. The PA findings are based on the 

information presented in Appendix A and Appendix B.

Findings

No PFAS releases relating to current of historical activities at the STA were identified during this 

PA. Table 7-1 summarizes the areas discussed in Sections 3 and 4 and shown in Figure 7-1, 

which were determined to have no suspected releases.

Table 7-1: No Suspected Release Areas

No Suspected 

Release Area Used by Rationale for No Suspected Release Determination

Armory ILARNG

Only portable ABC and wet chemical fire 

extinguishers (non-AFFF) are stored within the 

Armory. The kitchen hood fire suppression 

system uses a wet chemical agent and has 

never been discharged. 

Firehouse ILARNG

AFFF has never been present at the Firehouse. 

Deployed equipment is emptied and cleaned 

prior to retuning the STA. 

Telephone Pole Fire ILARNG Interviewees indicated that water was likely used 

in the emergency response incident. 

Two adjacent sources, the Sparta Fire Department and Sparta Community Airport, were identified 

as potential PFAS release areas. Based on the inferred groundwater flow direction, Sparta 

Community Airport may be potentially upgradient from the facility, and Sparta Fire Department is 

cross-gradient to the facility.

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 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 site observations. 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.

Sparta Training Area,

Sparta, Illinois

19

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

of PFAS were reviewed, 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: Summary of Uncertainties

Location Source of Uncertainty

Armory

The Armory was constructed in 1990 and has been operated by 

ILARNG since construction. Activities prior to 2007 (the extent of 

interviewee knowledge) are unknown. 

Firehouse The type of foam contained within the firetrucks when deployed 

is unknown. 

Telephone Pole Fire

The extinguishing agent used in response to the telephone pole 

fire is unknown, although the Sparta Fire Department Chief 

maintains that water and not AFFF was likely used due to the 

nature of the fire. 

Potential Future Actions

Based on the documented absence (2007-present) of the use or release of PFAS-containing 

materials at the STA, no AOIs were identified during the PA. Evidence does not indicate that 

current or former ARNG activities contributed to PFAS contamination to soil, groundwater, surface 

water, or sediment at the facility or adjacent areas. STA will not move forward in the CERCLA 

process.
