Groundwater Treatment Plant Modifications, Whittier Narrows Operable Unit, San Gabriel Valley Area 1 Super
Document Type
MND - Mitigated Negative Declaration

Document Description
USEPA proposes to modify the existing groundwater treatment plant in order to connect the plant to SGVWC's drinking water distribution system. The modifications would include construction of a storage tank, booster pump station, a connection between the storage tank and SGVWC's distribution system (located immediately adjacent to the treatment plant along Durfee Avenue), an emergency connection to the City of Whittier's drinking water distribution system, and relocation of the current chlorination unit. Construction for the clear well, booster pump station, and emergency connection, relocation of the chlorination unit, and the contingent modifications are entirely within the existing plant boundary. Construction for the pipeline to connect the SGVWC distribution line to the treatment plant may extend into Durfee Avenue.
