Jeff provided review and data analysis for this former dry cleaning facility that had released tetrachloroethylene (PCE) to site soil and groundwater. Work included site characterizations using direct push borings, soil gas surveys, well installations, and a remedial alternatives evaluation. He has also assisted in the development of a remedial program for the site. The project site consists of a dry-cleaning facility located within a commercial/retail center. Dry-cleaning operations occurred at the facility since 1974 and resulted in chlorinated solvent impacts to soil and groundwater beneath the site.As a result, the RWQCB opened a Spills, Leaks, Investigations, and Cleanups (SLIC)case and the site was referred to the Alameda County Water District (ACWD) for lead agency oversight. A series of soil and groundwater investigations identified a source area beneath the drycleaner suite and an adjoining retail suite. ENGEO prepared a Corrective Action Plan (CAP) and coordinated the in-situ chemical oxidation program that consisted of injecting 35,000 gallons of potassium permanganate to the subsurface to oxidize chlorinated solvents. The project is currently in the post-remediation monitoring phase. Stone Lock District Development - Consulting Services—West Sacramento, CA Project Engineer.
