Site Investigation and Risk Assessment
Representative projects of some of our Advisory Board members
In the future, this page will reflect news of the Foundation's projects.
Brownfields Redevelopment Projects, Port of Oakland, California: Program Manager
for two consecutive as-needed contracts to provide a wide variety of environmental
compliance services to the Port of Oakland.  Over 60 projects completed to-date,
including 11 investigations for redevelopment projects at the Oakland International
Airport, a Maritime berth, and two industrial properties that have since been
redeveloped as parks.  Investigations entailed designing and implementing soil and
groundwater sampling to provide the data needed for evaluating risk during and after
redevelopment and/or for predetermining soil disposal options during development.   
Risk assessments conducted in accordance with the SFWB’s Environmental
Screening Level (ESL) Tier 1 and Tier 2 risk assessment guidance.  All work conducted
on time and on or under budget and to the Port of Oakland and SFWB’s satisfaction.

Brownfield Site Investigation and Risk Assessment, Fortune 100 Semiconductor
Manufacturer, Santa Clara, California:
 Program Manager for this client for the past
twelve years.   Our initial investigations at this undeveloped site were follow-up to
previous sampling that had identified metals contamination.  Conducted several
phases of soil sampling to determine the nature, extent and likely source of the
contamination.  Also performed air modeling to assess the need for Proposition 65
warning, and determined that no such warning was warranted.  Based on soil
investigation results, presented data to the California Department of Toxic Substances
Control (DTSC) and negotiated a Voluntary Cleanup Agreement (VCA) for our client.  
Work under the VCA included risk assessment, Removal Action Workplan (RAW), RAW
implementation, and public participation activities.  Through the risk assessment,
conducted in accordance with Preliminary Endangerment Assessment (PEA) and other
DTSC guidance, demonstrated that the RA could be limited to institutional controls to
ensure the existing clean cover remains intact.  Cost for implementing this alternative
was $1M less than other alternatives.  RAW approved by DTSC and the public.  
Prepared all public participation documents and the deed restriction, and prepared and
implemented Operations and Maintenance (O&M) and Soil Management Plans.

Brownfield Environmental Investigation and Risk Management, Former US Army
Disciplinary Barracks, Lompoc, California:
 Program Manager for investigation and risk
evaluation of this former Army facility targeted for redevelopment by the federal Bureau
of Prisons (BOP).  Sites included two landfills, a vehicle wash rack/grease rack area, an
incinerator, and a skeet range.  Work scope included soil, soil gas, ground water, and
surface water investigations; human health and ecological risk assessment following
USEPA guidance; preliminary evaluation of remedial options for two of the areas; and,
negotiations with the U.S. Army, BOP, USEPA, Central Coast Water Board (CCWB), and
County of Santa Barbara for No Further Action on the remaining sites.  

Environmental Investigation and Risk Screening, DOE-funded Research Facility,
Davis, California:
 Managed investigation of 3-acre dog pens used in radiological
testing for almost 30 years.  Diffuse, low-level radionuclide, metal, and pesticide
contamination presented difficult challenge for investigation design and risk
management planning.  Used field screening methods, a phased investigation
approach, statistical methods, and risk-based action levels to cost-effectively
demonstrate that No Further Action is required for the dog pens soil.  Project required
frequent presentations to and negotiations with multiple stakeholders with varied
interests, including USEPA, Central Valley Water Board (CVWB), DTSC, Department of
Health Services (DHS), and University of California at Davis, all of which approved the
plans.

Hydrogeology Projects, City and County of San Francisco, California: Provided site
characterization and environmental compliance expertise on several projects under an
as-needed environmental services contract for this client and assisted in negotiations
with the SFWB, CVWB and DTSC on several surface water, ground water and sediment
issues related to these projects.  One project involved the proposed dredging of
sediment with high copper levels from a reservoir and placement of the sediment near
another surface water feature.  Regulatory concerns were addressed through sediment
and water quality sampling and biological and human health risk assessment.
Hydrogeologic Investigation, DOE-funded Research Facility, East Bay, San Francisco,
California: Managed investigation of 120-acre research facility in California Coast
Range.  Worked jointly with team of scientists from the facility.  Over 100 Solid Waste
Management Units (SWMUs) and other Areas of Concern with a wide range of potential
contaminants were identified and investigated.  Investigation methods included wipe
sampling, surface soil and water sampling, active and passive soil gas surveys,
geophysical surveys, soil borings, and nested well installation.  RCRA Facility
Assessment and RCRA Facility Investigation workplans completed.
