Wendy Cohen, CVRWQCB-SLIC Unit page 2 RE: Hess-Dubois Dry Cleaners Table 2 of the enclosed quarterly monitoring report listed TPH-ss at 1,500 ug/I for MW- 10 but the laboratory data sheets identified this detection as Gasoline Range Organics. This reporting detail was repeated for MW-6 in the same table. A discussion with the consultant indicated that the similarities of these detections resemble a gasoline pattern slightly more than they do Stoddard solvent. A UST site one block down gradient of this dry cleaner site will be undergoing a groundwater investigation soon. On March 29, 2002, EHD approved the February 12, 2002 work plan to install up to ten- paired CPT borings offsite and down gradient of the site. On June 5, 2002, the SWRCB Cleanup Fund denied reimbursement for this EHD approved work stating, "Corrective action costs associated with chlorinated solvents are not eligible for reimbursement from the Fund— only assessment and remediation of stoddard solvent contamination is eligible." EHD has discussed this site with Marty Hartzell in the UST Unit of the CVRWQCB and his recommendation was to forward the most current quarterly report to you with a request for the SLIC unit to oversee the investigation and cleanup of this Dry Cleaner/ solvent impacted groundwater site. Please provide your comments to Michael Infurna at (209) 468-3454 should you have any concerns and when you have made your decision.
