    Military Base Cleanups

    A quarter of all U.S. military bases shut down during base closings from 1988 through 1995 were in California. DTSC mobilized massive base cleanup efforts that have repositioned more than 70 percent of closed acreage for new uses.


    Brownfields Cleanups

    Brownfields are contaminated industrial and manufacturing sites that require cleanups before being developed for new uses. DTSC has cleaned up thousands of acres of brownfields to create new housing, offices, stores and jobs.


    Groundwater Cleanups

    Industrial byproducts and other contaminants can spread beyond surface soils and into one of California’s most precious resources, its groundwater. Many of DTSC’s cleanups involve successfully restoring the quality of groundwater.


    Mine Cleanups

    More than a century and a half of mining in California has created an estimated 47,000 abandoned mine land sites. DTSC’s cleanup efforts have led to new uses, including parks.
