When a release of PFAS occurs at a metal finishing facility, it is often due to the integrity of the wastewater system. Due to the persistence of PFAS and very low concentrations considered to be toxic, even water containing a small amount of PFAS can result in a large impact on the environment. If water can migrate into the subsurface, so can PFAS. Once in the soil, any water introduced into the soil can transport the PFAS into the groundwater.
The Californian chrome plating facilities are being required to test for PFAS even if there is no evidence of historical contamination at the property from any chemicals. Current testing is requiring the analysis of 25 different kinds of PFAS, including PFOS and 6:2 FTS.
Because such low concentrations of PFAS are considered to be toxic and their prevalence in common consumer products and tools, false-positive detections are common during the investigations for PFAS. False positives detections can lead to unnecessary expense and additional investigations. Therefore, selecting a knowledgeable, skilled, and experienced environmental consulting firm, is paramount to keeping the investigation as low cost as possible.
