Cleanup
Between 1999 and 2001 benthic toxicity tests found PAHs and mercury levels at up to 507 mg/kg and 13 mg/kg respectively at this site and a 20-acre (81,000 m2) portion was designated as an area of concern (AOC). The worst contaminated, AOC is adjacent to the former wastewater outfall which has now been relocated into San Pablo Bay. A California Environmental Quality Act (CEQA)-mandated mitigated negative declaration was completed and a corrective action plan has been designed. The plan which comes with a natural resource damage assessment will quarten off the AOC with a steel sheet pile and have the contaminated muds and sediment dredged and pumped into a disused treatment pond. In that treatment pond the toxic waste will be dried and then neutralized with a stabilizing agent like fly ash or cement. The inactive pond will at that time be regraded and capped with vegetation. The resportation project is scheduled for the summer of 2007. Castro Cove is named after Don Víctor Castro.
