Opinion: Legislation needed to defend local water systems from harmful PFAS chemicals

RESEARCH CONDUCTED BY the Environmental Working Group (EWG) detected PFAS contaminants in 74 water systems around California, which serve 7.5 million residents. Forty percent of the water systems tested positive for at least 70 ppt concentrations of PFOA and PFOS, both common PFAS. Additionally, it was reported that some of the water systems contained six other types of PFAS chemicals.

PFAS, or per- and poly-fluoroalkyl substances, are tightly bonded chemical compounds that are used for merchandise with insulation, stain- and heat-resistant qualities. These products are commonly found in household goods and fixtures, food packaging, firefighting foams, paint, turnout gears, and equipment used in the military. The man-made substances offer convenience and efficiency in the community’s day-to-day lives. However, the Environmental Protection Agency has found that PFAS is related to serious health issues and environmental pollution.
