4 - Savanna Depot Park

INVESTIGATION RESULTS The Environmental Baseline Survey (EBS) team from Science
Applications International Corporation (SAIC) identified and categorized
all sites and areas at the Savanna Army Depot Activity (SVDA) in accordance
with relevant regulations and guidance. This section presents the results
of the EBS investigation. Sites that were identified as part of previous
studies as well as new sites identified during the EBS process are
discussed in Section 4.1. Underground storage tanks (USTs) and aboveground
storage tanks (ASTs) were investigated and an inventory was compiled during
the EBS investigation and is discussed in Section 4.2. Adjacent
properties, including an assessment of potential sources of environmental
contamination, are described in Section 4.3. Non-Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA) related
environmental hazards potentially present at SVDA, including asbestos, lead-
based paint, polychlorinated biphenyls (PCBs), radionuclides, radon, and
unexploded ordnance (UXO), are discussed in Section 4.4. Remediation
efforts conducted at SVDA are described in Section 4.5. Worksheets A, B,
and C, which are used as a source for baseline site information during the
property transfer process and summarize the results of the EBS, are
provided in Appendix H.
1 PROPERTY CATEGORIZATION This section presents the categorization results of the EBS
investigation. Environmentally relevant sites that were identified prior
to the EBS and the new sites identified during the EBS process are
discussed. The history of each site is provided, as well as the assigned
Comprehensive Environmental Response Facilitation Act (CERFA) parcel
category. The categorization is based on former and current environmental
conditions as a result of installation operations. The seven categories
used for property classification are defined in Section 1.3. The level of
detail given for each site varies based on the amount of data available.
Detailed multimedia sampling has been conducted at some sites, whereas
others have received only a visual inspection. Also, the detail of a
site's history is based on available information from installation records
and documents, and interviews of former and current installation employees. Five environmental investigations have been conducted at SVDA to
identify and characterize, on an installation-wide basis, sites that may
pose environmental concern or require an environmental investigation.
These investigations identified 76 sites. Table 4-1 lists the previously
identified sites. The five investigations that identified these sites are
summarized below. . U.S. Army toxic and Hazardous Materials Agency (USATHAMA),
Installation Assessment, 1979-USATHAMA conducted an investigation
in 1978 to determine past and current use of toxic and hazardous
materials at SVDA and assess the likelihood of release of these
materials. A final report was published in January 1979. The
investigation did not include environmental sampling. The
investigation was conducted by reviewing available records,
interviewing former and current employees, and observing and
photographing the installation during a site visit. USATHAMA
identified 59 potential areas of contamination in the final report. . Environmental Science and Engineering, Inc. (ESE), Rapid Response
Environmental Surveys, 1982-ESE conducted an environmental survey
at SVDA from September 1980 to September 1981. A final report was
published in March 1982. This survey was conducted to screen the
sites identified by USATHAMA during the Installation Assessment
(1979) and identify sites that warranted additional investigation.
In the final report, ESE identified 34 potential areas of
contamination that warranted additional investigation. The sites
that were classified as having high contamination potential were
directly monitored by ESE, and sites that were classified as having
low contamination potential were monitored indirectly by reviewing
the analytical data from environmental samples collected from
downgradient sites that were associated with directly monitored
sites. In addition to environmental sampling, ESE conducted
geophysical surveys to locate UXO. Table 4-1. Previously Identified Sites |Site No.|Report |Categor|Previously Identified Site |
