Former Kaiser Aerotech Facility
Prologis
San Leandro, CA
Citadel EHS has provided long-term environmental remediation and redevelopment support for a former aerospace and aircraft manufacturing facility in San Leandro, California. Aerospace manufacturing operations occurred at the approximately 14-acre property from the mid-1950s through the 1990s, resulting in chlorinated volatile organic compounds, including trichloroethene (TCE) and its degradation products, in soil, groundwater, and soil vapor.

Santa Susana Field Lab
Envicom Corporation & Bhate Environmental Associates
Canoga Park, CA
The Santa Susana Field Laboratory (SSFL), located at 5800 Woolsey Canyon Road in Canoga Park, California, is a former U.S. government energy research and development facility. Although industrial operations ceased in 2006, the site contains residual radionuclide, soil, groundwater, and stormwater contamination. The responsible parties - Boeing, NASA, and the U.S. Department of Energy (DOE) - are conducting a comprehensive environmental cleanup to support long-term site restoration and safe future use.
