Superfund Explanation of Significant Difference for the Record of Decision (EPA Region 9): Lorentz Barrel and Drum Co. , San Jose, CA, April 24, 1998
The document presents the Explanation of Significant Differences (ESD) for a proposed change to the remedy chosen in the Operable Unit 2 Record of Decision (OU-2 ROD) for the Lorentz Barrel and Drum Superfund site (the Site). The OU-2 ROD was dated September 22, 1988, and addressed the remediation and monitoring of the shallow groundwater contamination which resulted from activities at the Site. Concentrations of organic contaminants at the Site have generally decreased since commencement of the groundwater treatment system in 1992. Based on the reductions in the concentrations of organic contaminants in the groundwater being extracted at the Site, and the inefficiency of the UV/Ox unit in its ability to reduce these organic contaminants to the discharge limits, the potentially responsible parties (PRPs) implementing the groundwater remediation program have requested that EPA approve a change to the current treatment system involving the removal of the UV/Ox treatment unit from the approved treatment program. The revised treatment system would consists of subjecting the contaminated groundwater to the GAC filters, exclusively.
