13. ABSTRACT (Maximum 200 words)
Dames 'and Moore has conducted a Remedial Investigation (RI) of the Presidio of San Francisco (PSF), CA. The objectives
of the RI included the determination of the nature and extent of contamination at PSF and to quantify both the human health
and ecological risk posed by that contamination. The report concludes that, in general, the Presidio does not pose a
significant risk to either human health or the environment. There are, however, a number of locations where elevated risks
are present. The remedial actions to abate those risks will be identified in a follow -on document called the "Presidio Main
Installation, Feasibility Study".

* 1. INTRODUCTION
This Executive Summary presents, in condensed form, the basis and results of the Final
Remedial Investigation (RI) conducted at the Presidio of San Francisco (PSF) Main
Installation. This summarized form of the RI report is intended to make the RI results more
accessible to all individuals who take an interest in the U.S. Army's efforts to identify and
remediate contamination resulting from the U.S. Army's activities at the PSF. To that end,
this Executive Summary provides the RI results in a concise form with a minimum of
technical jargon.
Because the PSF is so valuable for its scenic beauty and recreational use, the U.S. Army, the
National Park Service (NPS, which currently controls the PSF)), the State of California, and
the general public want to ensure that the area does not pose a risk to either human health or
the environment. As part of that effort, this Executive Summary serves as a convenient
reference to the RI results and to interpretive information that helps readers put the results
into a realistic perspective. The interpretation of results from RI studies is crucial. While
scientific study yields valid information on environmental contamination and associated
adverse effects, that data must be evaluated against inherent qualifying factors. Only then
can the most appropriate resources be committed to remediating contamination in the
environment.
The first three sections of this Executive Summary summarize the RI program; describe the
background of the PSF, its history, use and physical setting; and presents the investigative
methods used to collect data, along with information on how to interpret the risk assessment.
sections 4 through 14 describe the RI sites individually and present the findings of
contaminant investigations. The final section, section 15 summarizes the results of the
human health and ecological risk assessments.
1.1 Purpose of the Remedial Investigation
The purpose of the Main Installation RI is to characterize the nature and extent of
contamination resulting from U.S. Army activities at the PSF and to assess associated risks
to human health and/or the environment. When the PSF was closed as a U.S. Army base and
o:\proj\psf\ri\f-text\exsum.doc DAMES & MooRE
January 1997
Executive Summary Final RI Report, Presidio Main Installation
was transferred in 1994 to the National Park Service (NPS), it was required by the Base
Closure and Realignment Act to undergo environmental studies. As a result of early studies,
a number of sites were identified for investigation under the Main Installation RI. The Main
Installation RI is only one of several environmental studies initiated by the U.S. Army.
The specific objectives of the PSF RI are to
"* Identify and characterize potential sources of contamination at Main Installation sites
"* Define the concentrations and distribution of chemicals of potential concern in
environmental media (soil, water, sediments)
"• Evaluate the risks to human health and the environment which may be posed by these
chemicals.
In addition, data from the RI will support the Main Installation Feasibility Study (FS). The
FS will identify procedures to mitigate environmental contaminants that present an
unacceptable risk to human health or the environment.
The RI was conducted in accordance with the U.S. Environmental Protection Agency
(USEPA) guidance for activities performed under the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA) as amended by the Superfund
Amendments and Reauthorization Act, the National Environmental Policy Act of 1969
(NEPA), and the President's Council on Environmental Quality 40 Code of Federal
Regulations 1500-1508. The investigative approach was based on recommendations in the
USEPA's Guidancef or ConductingR emedial Investigations and FeasibilityS tudies Under
CERCLA (1988).
Furthermore, the procedures used in this RI are consistent with the Department of the Army
policy of integrating the NEPA and CERCLA processes. Local and State environmental
policies, laws, and regulations were also followed in conducting the RI.
1.2 Background on the Remedial Investigation
In December 1988, the U.S. Secretary of Defense's Commission on Base Realignments and
Closures recommended closure of the PSF. The PSF was transferred to NPS on October 1,
1994, under Public Law 92-5 89, and became part of the Golden Gate National Recreation
