Document Description
Pursuant to Chapter 6.5 of the Health & Safey Code, the Department of Toxic Substances Control is considering a request from PG&E for approval of an In-Situ Pilot Study Workplan that describes field activities for pilot tests to be conducted to evaluated in-situ technologies to reduce hexavalent chromium (CrVI) to trivalent chromium in groundwater in the Colorado River floodplain adjacent to the Topock site. The results of the pilot test would be used to: - Evaluate the effectiveness and persistence of selected in-situ reductants under actual site conditions; - Provide additional information on site conditions necessary to determine the feasibility of in-situ reduction of the CrVI plume; - Assist with the selection of preferred in situ reductant(s) for possible long-term site management.
