Document Description
DTSC is currently overseeing investigative and remedial activities at the PG&E Topock Compressor Station. Historical operations at the project site involved the use of chromium in the compressor station cooling water. Subsequent discharge of the cooling water resulted in chromium entering the groundwater aquifer.
PG&E has submitted the following three work plans to DTSC for approval:
1) In-situ Hexavalent Chromium Reduction Pilot Test Work Plan - Upland Plume Treatment (Arcadis 2006)
2) Work Plan for Hydraulic Testing Bedrock Wells (CH2M HILL 2006g and CH2M HILL 2006h)
3) Well PGE-6 Revised Decommissioning Work Plan (CH2M HILL 2006f)
