Confidential Dry Cleaners (Remedy 2009-2010; LTM through 2013)

During an environmental assessment (ESA Phase I) evaluation of a retail strip mall shopping center, the consultant discovered a release to the environment of perchloroethylene (PCE).  Due to the presence of several food service establishments proximal to the dry cleaning business, the regulatory authority requested indoor air samples to evaluate vapor intrusion potential.  AcuityES professionals responded with two separate evaluations.  First, an evaluation of indoor air samples was completed and compared to OSHA standards for dry cleaning operations.  Second, a sub-slab vapor intrusion assessment was completed and compared to the regulatory agency recommended exposure levels (applicable to the adjoining tenant spaces).  AcuityES professionals developed a source area removal remedy, and produced an exposure assessment for the dry cleaning operation and the adjoining tenant spaces to demonstrate that the residuals from the environmental release were not the primary risk when compared to OSHA standards for dry cleaning worker exposures as the result of typical equipment operation and handling for dry cleaned clothes.  The source removal was selected for the remedy, with long-term monitoring of the dry cleaning operation for compliance with OSHA standards.
