USGS Hinkley Chromium Study Overview

The Pacific Gas and Electric Company (PG&E) Hinkley Compressor Station is used to compress natural gas as the gas is transported through pipelines from Texas to California. Between 1952 and 1964, cooling water was treated with a compound containing chromium to prevent corrosion within the compressor station. This water was discharged to unlined ponds, resulting in contamination of soil and groundwater. The USGS and partner agencies began a 5-year study to evaluate the occurrence of natural and anthropogenic chromium near the contaminated area.

For more details regarding the study, the project proposal is available for review.
