Media Affected: Groundwater, Soils
Chromium is the hazardous substance of primary concern at the FHC site. While volatile organic compounds (VOCs), including tetrachloroethene (PCE) and trichloroethene (TCE) were detected in groundwater at the site, concentrations were extremely low and not directly linked to past activities at FHC. Chromium was found to be present in two forms, designated trivalent chromium and hexavalent chromium. Of the two, hexavalent chromium is the more hazardous. EPA classifies hexavalent chromium as a Group A carcinogen (evidence of human carcinogenicity) when inhaled. Both groundwater and soils were contaminated with high concentrations of hexavalent chromium. Exposure through ingestion of or direct contact with chromium-contaminated groundwater or soils may pose health risks.


Hide details for Cleanup ProgressCleanup Progress

This site is now cleaned up, we continue to monitor groundwater to ensure contaminants are not rebounding. We believe the site is ready for redevelopment. Actual cleanup began at the end of 2002. EPA demolished two vacant buildings that were located over the contaminant "hot spot." Then, EPA injected a reducing agent underground around the most concentrated contamination, forming a sort of underground fence to keep contamination from spreading. Any hexavalent chromium passing through this fence changes to non-toxic trivalent chromium. Within days of injection, the once highly-contaminated groundwater showed no detectable levels of hexavalent chromium. Over 180,000 gallons of water were treated in this way. Soils throughout the treatment zone also show no detectable levels of hexavalent chromium. Cleanup was completed in September 2003.
