Document Description
The approved project is a modification to the Topock Compressor Station Groundwater Remediation Project that was previously approved by the DTSC. The Topock Compressor Station Groundwater Remediation Project involves manipulation of subsurface water flow to move a contaminated groundwater plume with hexavalent chromium Cr(VI) and other chemicals of potential concern (COPCs), originating from past operations at the Pacific Gas & Electric Company (PG&E) Topock Compressor station (compressor station) site, through a treatment zone. This treatment zone or "in situ reactive zone (IRZ)" will be created by introducing a carbon substrate such as, but not limited to, ethanol, molasses, lactate, or whey to introduce microbial growth which, in turn, creates an environment where the Cr(VI) is reduced and precipitated.
