Superfund record of decision (EPA Region 9): San Gabriel Valley (Area 4), Puente Valley Operable Unit, La Puente, CA, September 30, 1998

Technical Report ·
OSTI ID:350776
This Interim Record of Decision (ROD) addresses the contamination at the Puente Valley Operable Unit (PVOU) located within the San Gabriel Valley Superfund Site in Los Angeles County, California. This ROD addresses ground water contaminated with volatile organic compounds (VOCs). The selected remedy is containment of ground water contaminated with VOCs in the shallow and intermediate zones at the mouth of Puente Valley to prevent further migration of existing ground-water contamination. This remedy includes performance criteria that will require extraction and treatment of contaminated ground water at certain locations along the downgradient edge of the contamination and will require continued monitoring and evaluation at other locations. Treated ground water will be provided to local water purveyors or discharged to Puente Creek, immediately upstream of San Jose Creek. In addition, this remedy includes monitoring in the shallow, intermediate, and deep ground-water zones at mid-valley and at the mouth of the valley.
