At both groundwater and surface water sites in Arizona, tetrachloroethylene (PCE) generally exceeded the current Arizona Health-Based Guidance Levels (HBGL).
It was found that PCE concentrations were in excess of the HBGL at various groundwater sites and in excess of the MCL at a single groundwater well 1.8 km (1.1 miles) north of the U.S.-Mexico border.
At this same well site, TCE was detected at a concentration greater than the HBGL. The concentrations of PCE and TCE were generally high in Nogales, Sonora, exceeding the HBGLs and MCLs, and lower in Nogales, Arizona.
