at STA proceed, the number of study areas, site names and waste types may vary. ATSDR will review new
information relating to public health evaluations at those study areas.

Table 3A. Trespassing at Selected Study Area Study Area Access Restrictions Physical Hazards Surface Soil
Contamination1 Comments2
A1 - Decontamination Mustard Burial Area Yes3 No Yes One to two dozen bags of clothing, decontaminated afer use
in mustard agent testing, were buried. The only contamination found at A1 is a drum confirmation sample (surface
soil).
A7 - Old Gravel Pit Landfill Yes4 - fenced October 1991 Yes Yes In the past, trespassers used the area for dirt biking
and target practice. The area is now fenced. Surface soil contamination is limited to two drum confirmations and
one localized diesel fuel spill.
A9 - POL Burn Area Yes4 No Yes The area is fenced but trespassing reportedly occurs. Fifteen surface soil samples
(including a drum confirmation sample) were collected at A9. Although metals, pesticides, VOCs and SVOCs were
detected in surface soil, only benzo[a]pyrene exceeded comparison values.
A11 - Leach Field Yes3 Yes No Building rubble and debris. A drum confirmaion sample was collected but
contaminants were below comparison values.
A12 - PCB Spill Remediation Yes3 No Yes Potential past exposure to PCBs by persons scavenging parts or
vandalizing transformers. PCB-contaminated soil was remediated in 1985.
P22 - Old Gravel Pit Yes3 - boundary fence improved in spring 1993 Yes No (nitroglycerin was detected but has no
comparison value) The area, which contains metallic debris, has been used for dirt biking. A six-foot chain linked
fence along the installation boundary now prevents access. Removal of limited surface soil and metallic debris is
planned (40).
P32 - Road and Railroad Intersection Yes3 Yes Not sampled The area is used for dirt biking. Domestic trash
dumping has occurred beyond installation boundary.
P36/37 - Former XXXXXXX Buildings T104 and T106 Yes4 - the buildings doorways have either been fenced or
welded shut. Yes Not sampled The buildings contain physical hazards and asbestos. Trespassing is a problem.
ATSDR recommened that the Army demolish the buildings (ATSDR Health Consultation, November 1992 -
Appendix 8). Additional field investigations, including surface soil sampling, are planned for both study areas (40).
P45 - Burned Area by Outside Fence Yes3 Yes No A drum confirmation sample contained arsenic (260 ppm) in
surface soil at a concentration below relevant comparison values. The arsenic level does exceed a comparison value
for residential soils (85); however, current land use is NOT residential. Surface soil removal with confirmatory
sampling is planned (40).
1 Only contaminants that were detected at concentrations exceeding comparison values are reported. Refer to
Table 4 for specific contaminant concentrations.
2 References: March 1994 Phase II SI (40), July 1993 RI/SI report (4), June 1993 Phase II workplan (6) and
ATSDR site observations (October 1992 and June 1993). Only surface soil data are presented because of possible
contact by trespassers who enter these study areas. Complete sampling information is described in the previously
referenced documents.
3 The perimeter of STA is fenced.
4 The Army has attempted to further restrict access to a few on-site study areas by installing additional fencing.
Table 3B. Selected Study Areas with Public Access Study Area Surface Soil Contamination1 Comments2
P7 - Patrol Road Waste Area A soil gas survey was done - no contaminants were detected. The reported chemical
waste disposal area is overgrown with vegetation. Samples from test pits and groundwater do not contain
contaminants at levels above comparison values.
P17 - Bldg T206 Cloth Burial Area Yes Wastes were buried. DDT and related compounds and arsenic (220 ppm)
were detected in a drum confirmation sample but at concentrations below relevant comparison values. The arsenic
level does exceed a comparison value for residential soils (85); however current land is NOT residential. Additional
surface soil sampling is planned (104).
P31 - Old Dump Yes3
Sediment contained elevated metals (Table 8)3 The area is used for recreational dirt biking. A drum confirmation
sample contained benzo[a]pyrene and lead at concentrations exceeding comparion values. Test pits in the area
contain debris but, contaminant concentrations do not exceed comparison values. Removals and confirmatory
sampling is planned (40, 104).
P34 - Vegetation Stress at Main Gate Not sampled No visible evidence of contamination. The area is associated with
an underground gas pipeline.
P42 - Off-Site Dump No Contaminants were not detected in surface soil samples at the site (40).
P43 - A and B - Disturbed Areas/Strain Vegetation Stress Not Sampled During the October 1992 site visit, ATSDR
staff walked the area which has several roads and trails through it. People appear to use the area because some trash
(beverage cans) was seen. No evidence of contamination was observed. There is no indication from investigations of
the area that past disposal of chemicals occurred.
P58 - small dump of domestic debris Yes Principally metals contamination, which appears limited to the wetland
area. Also some polyaromatic hydrocarbon and total petroleum hydrocarbon contamination. A remedial
investigation is recommended for the site (40).
