Dear Mr. Zalaskus:
Arsenic and lead soil sampling investigations have been conducted at Facilities 461 and 239 at Camp Pedricktown, New Jersey. Facility 461 is an above ground water storage tank located within the Base Realignment and Closure (BRAC) excess area, and Facility 239 is an elevated water storage tank located within the non-BRAC Army Reserve Enclave area. Enclosed for your review and approval are the following March 2000 reports prepared by Fort Dix on the arsenic and lead investigations. Electronic data deliverables for both reports will be provided under separate cover.
a. Arsenic and Lead Soil Sampling Investigation, Facility 461 (Water Tank), Camp Pedricktown, Oldmans Township, New Jersey; and
b. Arsenic and Lead Soil Sampling Investigation, Facility 239 (Water Tower), Camp Pedricktown, Oldmans Township, New Jersey.
The Camp Pedricktown water supply facilities are under consideration for transfer to the Pennsgrove Water Supply Company. Previous investigations have detected elevated arsenic and lead soil concentrations in several areas at Camp Pedricktown. Therefore, soil sampling investigations were conducted to assess the arsenic and lead concentrations in the area of Facilities 461 and 239 prior to the facility transfer. Based on these investigations, lead concentrations in both areas exceed the NJDEP residential and non-residential soil cleant1p criteria. Arsenic concentrations in both areas were below NJDEP residential and non-residential soil cleanup criteria. Action plans to address the elevated lead concentrations will be prepared and submitted under si,parate cover.

Arsenic and Lead Soil Sampling Investigation
Executive Summary
Facility 239 is a water storage tower located southwest of South A venue in the Army Reserve Enclave portion of
Camp Pedricktown, New Jersey. The tank has a nominal capacity of 125,000 gallons and was constructed in 1942
(Knighten, 2000; Woodward-Clyde, 1997). Facility 239 is currently used to supply potable water to Camp
Pedricktown. Previous investigations have detected elevated arsenic and lead concentrations in other portions of
Camp Pedricktown. Both arsenic and lead are, under certain circumstances, regulated by the New Jersey
Department of Environmental Protection (NJDEP) when present in the soil at concentrations greater than 20
milligrams per kilogram (mg/kg) and 400 mg/kg, respectively (IT Corp., 1999). This investigation was conducted to
determine the concentrations of arsenic and lead in the surface soil beneath the water tower. This investigation was
not intended to quantify the magnitude or extent of arsenic or lead in the surface soil.
On 6 January 2000, a member of the Base Realignment and Closure (BRAC) support team collected four surface
soil samples (0 to 6 inches below ground surface) immediately adjacent to (within I-foot) the water tower support
columns. The Fort Dix representative is a NJDEP certified Subsurface Evaluator, and the samples were collected in
accordance with NJDEP field sampling protocols. Laboratory analysis indicates that total arsenic concentrations are
below the testing instruments detection limit for all samples tested and total lead concentrations range from 2,740
mg/kg to a maximum concentration of 6,390 mg/kg. Site specific background concentrations of lead reportedly
range from 1.4 mg/kg to 66 mg/kg (Versar Inc, 1993). Based on the investigation results, the soil samples tested do
not contain regulated concentrations of arsenic but do contain regulated concentrations of lead. Lead-based paints
from the water tower are a potential source of the elevated lead concentrations. Additional investigation would be
necessary to assess the horizontal and vertical extent of the lead in the soils beneath the water tower.

Arsenic and Lead Soil Sampling Investigation
1.0 Introduction
Facility 239 is a water tower located southwest of South Avenue in the Army Reserve Enclave portion of Camp
Pcdricktown, New Jersey. The tank has a nominal capacity of 125,000 gallons and was constructed in 1942
(Knighten, 2000; Woodward-Clyde, 1997). Facility 239 is currently used to supply potable water to Camp
Pedricktown. Previous investigations have detected elevated arsenic and lead concentrations in other portions of
Camp Pedricktown. Both arsenic and lead are, under certain circumstances, regulated by the New Jersey
Department of Environmental Protection (NJDEP) when present in the soil at concentrations greater than 20
milligrams per kilogram (mg/kg) and 400 mg/kg 1, respectively (IT Corp., 1999). This investigation was conducted
to determine the concentrations of arsenic and lead in the surface soil beneath the water tower. This investigation
was not intended to quantify the magnitude or extent of arsenic or lead in the surface soil.
2.0 Sampling Method
On 6 January 2000, a member of the Fort Dix BRAC support team collected four surface soil samples from
immediately adjacent to the water tower support columns, Figure 1. The Fort Dix representative is a NJDEP
,ertified Subsurface Evaluator, and the samples were collected in accordance with NJDEP field sampling protocols.
The samples were identified as follows:
• Environmental Samples
? WT-10600-A
};,,, WT-10600-B
};,,, WT- I 0600-C
};,,, WT-10600-D
• Quality Control Sample
::,.. WT-10600-FB
WT= Facility 239 water tower, I0600=sampling date, A-D = sampling location, and FB = Field Blank
rhe soil samples were collected twelve inches from the north side of the water tower support columns using a
J,:dicated, decontaminated stainless steel spoon (one spoon per sample location). Soil was collected from O inches
·.1.j 6 inches below the ground surface (bgs) and placed into an aluminum foil lined I-gallon steel bowl,
' 1·0mogenized, and placed into pre-labeled half-pint sample jars supplied by the testing laboratory (QC Incorporated).
:he sample locations were biased to areas free of vegetation. Sample locations WT-10600-C and WT-10600-D
,,~re free of vegetative cover.

Arsenic and Lead Soil Sampling Investigation
The environmental samples were tested for total arsenic and total lead by United States Environmental Protection
Agency (U.S. EPA) procedure SW 846, method 6010. QC laboratory Inc. performed all the chemical testing and is
certified in New Jersey (Certificate No. 77166). A copy of QC laboratory's certificate is provided in Appendix 2.0.
Standard quality control and assurance (QA/QC) practices were employed in the conduct of this investigation. The
stainless steel sampling spoons were decontaminated using NJDEP methods as follows:
• Tap water and phosphate free detergent wash
• Tap water rinse
• Distilled water rinse
• Air dry
• The decontaminated sampling spoons were then wrapped in aluminum foil (polished side out) for transport
to the site
The QA/QC practices also included the preparation of a chain-of-custody form and the collection and analysis of a
field blank. The field blank is an aqueous sample consisting of distilled/deionized water poured over the
Jccontaminated sampling tool (rinsate). For this investigation the rinsate was collected in a 500-milliliter plastic jar
:mpplied by QC laboratory. The field blank was containerized and tested in a fashion similar to the environmental
~amples to assess the potential for arsenic and lead cross contamination. The plastic jar contained a premeasured
amount of nitric acid to preserve the sample. After filling the field blank sample jar with rinsate water, the jar was
~caled and placed in the cooler with the environmental samples. The field blank was tested using U.S. EPA method
200.7 for both arsenic and lead.
3.0 Test Results and Findings
lhc soil samples were brown in color and consisted of medium to fine sands with trace amounts of silt. A black
vrganic like soil layer was encountered at 6 inches bgs at WT-10600-C and WT-10600-D. Paint chips were
lJbscrved in the soil at WT-10600-D and were observed in sample WT-10600-D. In general, the soil was moist and
very loosely compacted. The analytical test results are summarized in Table 1.0. The laboratory report is included
11 Appendix 1.0. The field blank results indicate that no apparent cross contamination occurred between the
1ampling equipment and the sample.
~- O Conclusions/Recommendations
r h~ ;malytical test results indicate the soil samples ttsted do not contain regulated levels of arsenic but do contain
rq~ulated levels of lead. Site specific background concentrations of lead reportedly range from 1.4 mg/kg to 66
'"l'/kg (Versar Inc, 1993). Lead-based paints from the water tower are a potential source of the elevated lead
! he concentrations provided are based on the NJDEP's ·'Residential Direct Contact Soil Cleanup Criteria". The NJDEP's "Non-residential ",. •,1 Contact Soil Cleanup Criteria" for arsenic and lead are provided in Table 1.0 of this report.
