Executive Summary

The United States (US) Army Corps of Engineers (USACE) Baltimore District on behalf of the

Army National Guard (ARNG) G9, Cleanup Branch contracted AECOM Technical Services, Inc.

(AECOM) to perform Preliminary Assessments (PAs) and Site Inspections (SIs) for

Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA) Impacted Sites at ARNG

Facilities Nationwide. 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 during firefighting

activities or training, although other PFAS sources are possible.

AECOM completed a PA for PFAS at Plant City Readiness Center (RC) in Plant City, Florida, to

assess potential PFAS release areas and exposure pathways to receptors. Historical aerials

imagery shows an armory as early as 1991. Plant City RC (also referred to as “the facility”) under

the current lease, which began in July 1983, extends for a period of 99 years between Florida

ARNG (FLARNG) and Plant City. Based on the USEPA Unregulated Contaminant Monitoring Rule

3 (UCMR3) data, it was indicated that PFAS were detected in a public water system above the

USEPA Health Advisory level within 20 miles of the facility.

The performance of this PA included the following tasks:

· Reviewed data resources to obtain information relevant to suspected PFAS releases

· Conducted a 1-day site visit on 5 February 2019

· Interviewed current Plant City RC personnel during the site visit including FLARNG

operations staff and Plant City Fire Department Station No. 1 staff

· Completed visual site inspections (VSIs) at known or suspected PFAS release locations and

documented with photographs

Two areas, Plant City RC Armory and Field Maintenance Shop (FMS), have been identified as No

Suspected Release (Figure ES-1). Based on the documented absence (1986-present) of the use

or release of PFAS-containing materials at Plant City RC, no areas of interest (AOIs) were

identified during the PA. Evidence does not indicate that current or former ARNG activities

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

adjacent areas. Plant City RC will not move forward in the Comprehensive Environmental

Response, Compensation, and Liability Act (CERCLA) process.

1. Introduction

1.1 Authority and Purpose

The United States (US) Army Corps of Engineers (USACE) Baltimore District on behalf of the

Army National Guard (ARNG) G9, Cleanup Branch contracted AECOM Technical Services, Inc.

(AECOM) to perform Preliminary Assessments (PAs) and Site Inspections (SIs) for

Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA) Impacted Sites at ARNG

Facilities Nationwide under Contract Number W912DR-12-D-0014, Task Order

W912DR17F0192, issued 11 August 2017, and Modification 01 issued 30 September 2017. The

ARNG is assessing potential effects on human health related to processes at their facilities that

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

releases of aqueous film forming foam (AFFF) although other sources of PFAS are possible. In

addition, the ARNG is assessing businesses or operations adjacent to the ARNG facility (not

under the control of ARNG) that could potentially be responsible for a PFAS release.

PFAS are classified as emerging environmental contaminants that are garnering increasing

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

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

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

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

Health Advisories for PFOA and PFOS in May 2016, but there are currently no promulgated

national standards regulating PFAS in drinking water.

This report presents findings of a PA for PFAS at Plant City Readiness Center (RC) in Plant City,

Florida, in accordance with the CERCLA, as amended, the National Oil and Hazardous

Substances Pollution Contingency Plan (40 Code of Federal Regulations [CFR] Part 300), and

USACE requirements and guidance.

This PA documents locations where PFAS may have been released into the environment at Plant

City RC (also referred to as “the facility”). The term PFAS will be used throughout this report to

encompass all PFAS chemicals being evaluated, including PFOS and PFOA, which are key

components of AFFF.

1.2 Preliminary Assessment Methods

The performance of this PA included the following tasks:

· Reviewed data resources to obtain information relevant to suspected PFAS releases

· Conducted a 1-day site visit on 5 February 2019

· Interviewed current Plant City RC personnel during the site visit including Florida ARNG

(FLARNG) operations staff and Plant City Fire Department Station No. 1 staff

· Completed visual site inspections (VSI) at known or suspected PFAS release locations and

documented with photographs

1.4 Facility Location and Description

Plant City RC is located at 4004 North Airport Road, Plant City, Florida in Hillsborough County,

western central Florida (Figure 1-1). The facility is surrounded by urban and suburban

developments, including the Plant City Municipal Airport to the south. Over one third of the land

use in Plant City is agricultural, and a quarter of the city is residential. Over 89% of this residential

land use is in the low to medium density category (Public Works Department/Engineering Division

[PWDED] 2002).

The facility contains an armory with dining, office space, and an associated vehicle storage and

vehicle maintenance shop. The facility’s perimeter is bounded by fences. The Plant City RC has

a 99-year lease from Plant City that began in 1983.

1.5 Facility Environmental Setting

Hillsborough County lies within the Polk Upland and Zephyrhills Gap physiographic units. Land

elevations vary from approximately 30 feet to over 100 feet above the National Geodetic Vertical

Datum (NGVD) (PWDED 2002).

1.5.1 Geology

The facility is underlain by a thick sequence of sedimentary strata divided into an upper zone of

unconsolidated sediments and a lower zone of consolidated carbonate rock.

At land surface, undifferentiated sediments including silt, sand, and clay form surficial deposits

that vary in thickness from less than 10 feet in coastal areas to over 100 feet in paleokarst

depressions or in sand ridges. Typical thickness of the surficial deposits varies from 20 to 50 feet.

In low lying areas near lakes and streams, thin layers of organic material mix with the surficial

deposits. At Plant City RC, it is estimated that the sediments range from 20 to 50 feet thick below
PFAS Preliminary Assessment Report

ground surface (bgs). Pleistocene-aged silts and clays form the base of the undifferentiated

sediments (Spechler 2007).

Underlying the unconsolidated material is a series of Tertiary-aged limestones and dolomites that

form the carbonate platform of peninsular Florida. The sequence of carbonate rocks includes, in

descending order, the following formations: Bone Valley formation, Peace River formation, and

Tampa Member of the of the Arcadia Formation of the Hawthorn Group, Suwannee Limestone,

Ocala Group, Avon Park, Oldsmar, and Cedar Key Formations. A lithographic change from

limestone and dolomite to a sequence of gypsiferous dolomite begins in the lower portion of the

Avon Park Formation and continues into the Oldsmar and Cedar Key Formations. The top of this

lithologic change marks the middle confining unit of the Floridan aquifer system. The middle

confining unit is generally considered the base of the freshwater production zone of the Upper

Floridan aquifer (Spechler 2007).

The Tampa Member of the Arcadia Formation of the Hawthorn Group is a tan-colored carbonate

and sand mixture, which can contain variable amounts of clay. The Tampa Member can be

fossiliferous and may also contain phosphate grains and chert. The Tampa Member ranges from

50 to 150 feet in thickness. The Suwannee Limestone consists of two rock types; the upper portion 

is tan-colored, crystalline limestone containing prominent gastropod and pelecypod molds, and

the lower portion is cream-colored limestone containing foraminifera and pellets of micrite in a

finely crystalline limestone matrix. The Suwannee Limestone varies from 150 to 300 feet in

thickness (Spechler 2007).

The Peace River Formation is composed of interbedded quartz sand, clay, and carbonates, with

variable amounts of phosphate. Siliciclastics, however, are the predominant lithology, comprising

more than two-thirds of the formation. The top of the unit generally ranges from about 125 feet

above to 125 feet below NGVD 1929. The Bone Valley Member is a clastic unit consisting of

pebble- or gravel-sized phosphate fragments and sand-sized phosphate grains in a matrix of

quartz sand and clay (Spechler 2007).

The Ocala Group contains a series of limestones that are generally soft, friable, porous, and

fossiliferous. This unit is late Eocene in age and ranges in thickness from 90 to 300 feet. The Avon

Park Formation comprises brown, highly fossiliferous, soft to well-indurated, chalky limestone and

a gray to brown, very fine microcrystalline dolomite. The Avon Park Formation ranges from 300

to 500 feet in thickness (PWDED 2002).

1.5.2 Hydrogeology

The principal hydrogeologic units within the watershed are the surficial aquifer, the intermediate

confining unit, the Upper Floridan aquifer, middle confining unit and the Lower Floridan aquifer

(Trommer 2009). The discussion below focuses on the uppermost aquifer, as it is the most likely

to be affected by PFAS releases.

The surficial aquifer resides within unconsolidated deposits of fine-grained sand with an average

thickness of 30 feet. Due to the karst geology of the region, the thickness of the sand can be

highly variable. Rainfall is the primary influence on water table elevation, with annual highs in

most years occurring during the end of the wet season, and annual lows occurring near the end

of the dry season. The direction of groundwater flow varies locally and is significantly influenced

by the topography of the land surface (PWDED 2002).

The depth to water table at Plant City RC is approximately 3.5 to 6 feet (US Department of

Agriculture [USDA] 2019). Locally at Plant City RC, the groundwater flow direction is

predominantly to the north-northeast (Figure 1-2). There are three public supply wells within 0.5

miles of Plant City RC which range in depth from to 290 to 746 feet, and one public supply well

within 1 mile of Plant City RC which has a depth of 746 feet. The public supply wells are not

immediately downgradient of the facility. There are no drinking water/public supply wells on the

facility, and drinking water for Plant City RC is supplied by public utilities, City of Plant City Utility.

Based on the USEPA UCMR3 data, it was indicated that PFAS were detected in a public water

system above the USEPA Health Advisory level within 20 miles of the facility (Appendix A).

1.5.3 Hydrology

Plant City RC is within the Pemberton Creek Watershed (Figure 1-3). The Pemberton Creek

Watershed is approximately six miles in length and receives stormwater runoff from Spartman

Branch, which serves as major stormwater conveyance feature for Plant City. Spartman Branch

located north of Plant City RC. This channel at one time may have been a shallow natural creek,

but over the years has experienced extensive channelization through a variety of projects and

man-accelerated erosion processes. Pemberton Creek watershed flows to the west after passing

under Wallace Branch Road. The character of the creek is a rather flat-bottomed channel that is

densely vegetated. The system passes through several wetlands (PWDED 2002).

1.5.4 Climate

The climate of the Pemberton Creek Area watershed, and for Hillsborough County as a whole, is

classified as humid subtropical. Winter rainfall is, for the most part, relatively light and is generally

associated with the weak cold fronts that descend from the northern part of the country and travel

south through the region (PWDED 2002).

In January, the average temperature is 70.1 degrees Fahrenheit (°F). June, July, and August have

the highest average temperatures, at 90°F. The greatest mean monthly precipitation occurs in

July and August. The average annual precipitation is 46.3 inches (National Oceanic and

Atmospheric Administration [NOAA] 2019).

The Rainy season coincides with the occurrence of most tropical storms and hurricanes. The

conditions are conducive for regular, convective afternoon and evening thunderstorms. These

summer events, which can be very localized, are highly variable in both intensity and volume. The

larger, normal summer storm events and those associated with tropical systems can cause

flooding problems (PWDED 2002).

1.5.5 Current and Future Land Use

Plant City RC currently contains an armory with dining, office space, an outdoor vehicle storage

area for the ARNG, and a vehicle maintenance shop. The armory complex includes parking areas.

Access to the facility is controlled, and land use is not expected to change.

2. Fire Training Areas

Through Environmental Data Resource Reports and interviews with Plant City RC personnel who

had knowledge dating back to 1999, no FTAs were identified within the Plant City RC facility

during the PA. Aerial photos covering 1991 to present show no sign of an FTA, and development

of the property has remained relatively unchanged from 1991 to present. Interview records appear

in Appendix B.

3. Non-Fire Training Areas

Two non-FTAs where PFAS were potentially released were also inspected during the PA. A

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

Interview records appear in Appendix B. Photographs appear in Appendix C.

3.1 Armory

The Armory is located in the center of the property (Figure 3-1). The geographic coordinates are

28° 0'14.57"N; 82° 9'39.66"W. The armory is used for training drills and is outfitted with a water

fire suppression system that was installed approximately 4 years prior to the site visit. During the

site visit, ABC Dry chemical extinguishers were found throughout the facility. The kitchen portion

of the armory is outfitted with a fire suppression system. At the time of the visit and to interviewee

knowledge dating back to 1999, the fire suppression system contained potassium carbonate

solution. However, FLARNG confirmed no AFFF-containing materials were used at the facility

since its construction. A potential PFAS release to the environment at the armory is not suspected.

3.2 Field Maintenance Shop (FMS)

The FMS is located in the north east portion of the property (Figure 3-1). The geographic

coordinates are 28°0'17.94"N; 82°9'39.25"W. During the site visit, ABC Dry chemical

extinguishers were found throughout the facility. At the time of the visit and to interviewee

knowledge dating back to 2013, there have been no fires on site at the FMS. The FMS is equipped

with an overhead water fire suppression system. Firetrucks were not serviced for maintenance at

the FMS. A fuel point previously existed on site that was decommissioned, and the tank was

removed. A potential PFAS release to the environment at the FMS is not suspected.

6. Preliminary Conceptual Site Model

Based on the PA findings, no release areas were identified, therefore, there are no AOIs at Plant

City RC. A conceptual site model (CSM) identifies three components necessary for potentially

complete exposure pathways related to a site: (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 that originate at Plant City RC or from activities associated with

Plant City RC.

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 Plant City RC. The PA findings are based

on the information presented in Appendix A and Appendix B.

7.1 Findings

No PFAS releases relating to current or historical activities at Plant City RC were identified during

this PA. Table 7-1 summarizes the areas discussed in Section 3 and shown in Figure 7-1, which

were determined to have no suspected release:

Interviewees indicated the fire extinguishers

7.2 Uncertainties

A number of information sources were investigated during this PA to determine the potential for

PFAS-containing materials to have been present, used, or released at the facility. Historically,

documentation of PFAS use was not required because PFAS were considered benign. Therefore,

records on the disposition of PFAS or the use of PFAS in training, firefighting, or other nontraditional activities, were not typically kept by the facility or available during the PA.

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

with personnel who had direct knowledge of 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 was first used (1969 to present), and a reliance on personal

recollection. There is also a possibility the PA 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, current personnel were interviewed, and potential source areas were

visually inspected.

however FLARNG confirmed no AFFFcontaining materials were used at the

facility since its construction. EDR aerial

photographs provided limited information

on site development over time.

7.3 Potential Future Actions

Based on the documented absence (1986-present) of the use or release of PFAS-containing

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

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

water, or sediment at the facility or adjacent areas. Plant City RC will not move forward in the

CERCLA process.
