Polychlorinated biphenyls (PCBs) are a group of legacy pollutants formerly used in commercial and industrial processes, with peak use between 1950 and 1980. "Old Industrial" indicates that an area's land use was Industrial prior to 1980 and has not yet been redeveloped. Regional monitoring data demonstrate higher loads of PCBs in stormwater runoff from Old Industrial areas, compared with other land uses types. In order to reduce PCBs runoff to the Bay, the City will investigate and treat Old Industrial areas, on a parcel-by-parcel basis. Investigation occurs through sample collection and lab testing, as well as desktop analysis. Treatment to control or abate PCBs runoff may include redevelopment, full trash capture device installation, enhanced street sweeping, and implementation of BMPs or cleanup on confirmed source properties. This layer shows the current investigation and treatment status for each Old Industrial parcel in San Jose. Data updated annually.
