A dry cleaning facility operated from 1947 to 2014. Fugro was retained by California Department of General Services to assess conditions, address risks posed, and to remediate the Site to allow redevelopment. The facility used a variety of dry cleaning solvents including tetrachloroethene (PCE) and the petroleum-based Stoddard Solvent. Contaminant plumes of the various chemicals of concern (COCs) are commingled onsite.
The Site is located in a dense urban setting with low income and market rate housing, restaurants and a child care facility as direct neighbors. Subsurface conditions at the Site are complex with sandy silts, dense silts, silts and clays, silty sands, and cobble/boulders. Based on the soil matrix, three water bearing zones were identified. Fugro’s focus was on the shallow groundwater because it is the source of vapor intrusion risk. The groundwater plume has been delineated to extend below several city blocks presenting unique challenges in development of the Conceptual Site Model.
