Site Cleanup

The Regional Water Board oversees site investigation and cleanup for unauthorized releases of pollutants to soils and groundwater and in some cases to surface waters or sediments. Sites include industrial facilities, dry cleaners, underground tanks, and aboveground tanks. Much of the pollution is due to past waste disposal and handling practices, as well as spills and leaks. New sites are discovered as a result of recent spills, property transactions, or nearby environmental investigations. Cleanup of Brownfields has become a new focus of our site cleanup programs, to address polluted properties in under-utilized urban areas.

The Regional Water Board oversees site cleanup through several programs:

Underground Storage Tank Program (UST) – mostly leaking underground fuel tanks
Site Cleanup Program (SCP) – range of non-fuel sites
Department of Defense Program (DOD) – open and closed military bases
Chapter 15 Waste Discharge Requirements program (Ch. 15) – discharges to land including landfills

You can find information on sites overseen by the Water Board and County Health agencies by visiting Geotracker, our on-line site cleanup database. Once there, select the “site/facility finder” button and use the search tool to find the site you are interested in.

The Water Board is one of several regulatory agencies that oversee such cleanup work in the Bay Area. Others include: the California Department of Toxics Substances Control (DTSC) and the nine County Health agencies. You can find information on sites overseen by DTSC by visiting Envirostor, a similar on-line site cleanup database.
