Last year, 3M reached a settlement worth $10.3 billion with water systems across the U.S. that will help pay to clean up drinking water contaminated with PFAS, while DuPont de Nemours Inc ...
The new drinking water standard would limit contamination from six of the most toxic PFAS compounds by requiring water utilities to test for their presence and then take action to remove the ...
The EPA will provide $9 billion to address PFAS contamination, including a $1 billion grant program for initial water testing and treatment. The feds have also made available $12 billion to ...
The water in and around at least 126 U.S. military bases has been contaminated by high levels of PFASs because of their use of firefighting foams since the 1970s, according to a study by the U.S. Department of Defense. Of these, 90 bases reported PFAS contamination that had spread to drinking water or groundwater off the base.
Collectively, the EPA estimates it will cost $1.5 billion per year for America’s 66,000 public drinking water systems to monitor their water for PFAS, inform customers of the results and find ...
In acidic form it is a highly reactive strong acid. In its conjugate base form as a salt it is stable and commonly ion paired with ammonium. In the commercial product Surflon S-111 (CAS 72968-3-88) it is the primary compound present by weight. PFNA is used as surfactant for the production of the fluoropolymer polyvinylidene fluoride.
June 2019 In what was described as a "huge step toward cleaning up the prevalence of—and prevent further contamination from—PFAS chemicals in ground, surface and drinking water" the Department of Environmental Services of the state of New Hampshire submitted a "final rulemaking proposal" for new, lower maximum contaminant levels (MCLs ...
In the new EPA regulations, PFOA and PFOS, two of the most well-studied and potentially toxic chemicals, cannot exceed 4 parts per trillion in drinking water. The prior health advisory set a limit ...
