The military is the most common culprit named among the 168 water systems that pointed to a PFAS source and also reported contamination above limits the EPA set earlier this year, USA TODAY's ...
Between 2016 and 2021 the U.S. Geological Survey (USGS) tested tap water from 716 locations across the United States, finding PFAS levels exceeding the EPA advisories in approximately 75% of samples from urban areas and in approximately 25% of rural areas. [77] In April 2024 EPA published final drinking water standards for six PFAS: PFOA; PFOS
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. [135]
What the EWG found is that filters’ effectiveness at reducing PFAS in tap water varied. Here’s how some of the most popular filters stacked up in EWG’s tests. Travel Berkey: 100% removal of ...
Of the 66,000 public drinking water systems impacted by the new standards, the EPA estimates that between 4,100 and 6,700 will eventually have to take action to reduce PFAS contamination.
Following initial discoveries of groundwater contamination in 2002, the Minnesota Department of Health conducted numerous studies –concluding in 2008, 2010, and 2014 – on the level of PFAs found in the bloodstreams of exposed residents. On February 20, 2018, the state of Minnesota settled its lawsuit against 3M in exchange for $850 million.
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" [101] the Department of Environmental Services of the state of New Hampshire submitted a "final rulemaking proposal" for new, lower maximum contaminant levels (MCLs ...
If the rule is finalized and implemented, public water systems will be required to monitor for these chemicals, notify the public and reduce PFAS contamination if levels exceed the proposed standards.
