Risk Based Corrective Action Analysis, IASCO Flight Training Center, Napa, California: ADH's Senior Geologist, Mr. Matt Bromely, P.G., Performed RBCA Risk Assessment to protect aquatic life and downstream marshland biota in Fagan Creek from an up gradient leaking underground storage tank site. Mr. Bromely prepared and presented empirical model of past, current, and predicated future groundwater contaminant migration, degradation rates, as well as geographic and temporal plume dynamics and contaminant discharge into creek. The model justified no active remedial measures and limited monitoring to verify modeled conditions.

U.S. Navy CLEAN Program, Pearl Harbor Shipyard RI/FS, Oahu, Hawaii: ADH's Senior Engineer, Mr. Tim Cook, PE, PG, CEG, managed several RI/FS projects at Pearl Harbor to delineate the extent and determine the human risk from lead, petroleum hydrocarbons, polychlorinated biphenyls (PCBs), and VOCs from numerous contaminant sources. Detailed Tier 2 Health Risk Assessments were conducted to determine cleanup levels protective of human and environmental receptors for each site, several remedial options were examined, and the optimal system was selected and designed.

As part of a current effort to clean up military bases, ADH's Senior Hydrogeophysicist, Dr. Barry Keller, has been involved in numerous geologic and geophysical investigations, remediation and hazardous waste management permitting at Navy and Air Force facilities in California. A recent project involves removal of free-phase hydrocarbon at a Navy National Environmental Leadership (NEL) site located in San Diego Bay.

ADH's President and Principal-In-Charge, Mr. Alessandro D. Hnatt, was Project Manager for the Ecological Assessment (EA) Naval Air Station, Alameda Comprehensive Long-Term Environmental Action Navy (CLEAN) as performed for the Department of the Navy, Western Division, Naval Facilities Engineering Command in association with two other subcontractors. The EA was performed in accordance with 1992 EPA risk assessment guidelines and the Apparent Effects Limits (AET) approach to evaluating ecological effects due to contaminated sediments in aquatic systems. Five Installation Restoration Program study areas were assessed in a two-tiered approach consistent with CERCLA and the 1986 Superfund Amendments and Reauthorization Act (SARA) including a small portion of the San Francisco Bay, a lagoon, a harbor and two landfills.

ADH's President and Principal-In-Charge, Mr. Alessandro D. Hnatt, was the Project Manager for the 1995-96 and 1996-97 Hunters Point Shipyard, Naval Station Treasure Island, and Naval Air Station (NAS), Alameda NPDES General Industrial Permit Monitoring Programs. Responsibilities included: primary client contact to prime contractor, Engineering Field Activity (EFA) West and on-site U.S. Navy personnel; planning, implementation and supervision of all field investigations; budget management; supervised and executed special Non-Point Source (NPS)/illicit discharge field investigations; supervised installation restoration investigations; performed quarterly BMP inspections of industrial activity sites, wrote corrective action plans and tracked BMP implementation; planned and implemented all storm event, dry weather sampling, and monthly dry weather and wet weather field observation reporting in respect to SWRCB's Inland Surface Water and Bays and Estuaries receiving water criteria; analytical data QA/QC; technical litigation support to EFA West and the U.S. Department of Justice; senior editor for each naval facilities' respective storm water pollution prevention plans (SWPPP), sampling and monitoring plans, and annual reports.

ADH's Senior Engineer, Mr. Garry Reid, PE, was responsible for numerous data evaluation, validation and conversion projects in the commercial and government sectors, including successfully converting environmental data from the largest Air Force facility into GIS\Key format.
