The site consisted of a suite in a retail shopping center that once contained a dry cleaner.  Soil gas samples indicated a leak of perchloroethene (PCE or “perc”) occurred but did not pose a threat to indoor air. 

Groundwater (located at less than 5 feet),  investigation defined the extent of contamination (LTCP # 3 and 4) and based on the low risk the RWQCB granted case closure under the LTCP.
