Uranium. Radium. Arsenic. These chemicals are known to cause cancer. However, these are not the only contaminants in tap water across the United States. A recent study by the U.S. Geological Survey reveals that approximately 45% of the country’s tap water contains per- and polyfluorinated alkyl substances (PFAS). While there are over 12,000 variants of PFAS, the study specifically examined 32 types, underscoring the limitations of current detection methods. Thankfully, the Environmental Protection Agency (EPA) has introduced new limits on PFAS, targeting six prominent variants: PFOA, PFOS, GenX, PFBS, PFNA, and PFHxS. Referred to as maximum contaminant levels (MCLs), these standards dictate
