US Water Likely Contains More 'Forever Chemicals' Than EPA Tests Show (theguardian.com) 84

An anonymous reader quotes a report from the Guardian: In May 2021, a celebration for Portsmouth, New Hampshire's new $17m water treatment facility drew local and national officials who declared the city's water free of toxic "forever chemicals." Firefighting foam from the nearby Pease air force base had polluted the water for decades with per- and polyfluoroalkyl substances (PFAS), and in recognition of the public health threat the US military funded the city's new filtration system. Officials said after implementing the upgraded filtration, testing no longer found detectable levels of PFAS chemicals in the water. They called the work in Portsmouth a "national model" for addressing PFAS water contamination. "We are here to celebrate clean water," Senator Maggie Hassan said at the time. But the water may not be clean after all.

A Guardian analysis of water samples taken in Portsmouth and from eight other locations around the United States shows that the type of water testing relied on by the US Environmental Protection Agency (EPA) -- and officials in towns such as Portsmouth -- is so limited in scope that it is probably missing significant levels of PFAS pollutants. The undercount leaves regulators with an incomplete picture of the extent of PFAS contamination and reveals how millions of people may be facing an unknown health risk in their drinking water.

The analysis checked water samples from PFAS hot spots around the country with two types of tests: an EPA-developed method that detects 30 types of the approximately 9,000 PFAS compounds, and another that checks for a marker of all PFAS. The Guardian found that seven of the nine samples collected showed higher levels of PFAS in water using the test that identifies markers for PFAS, than levels found when the water was tested using the EPA method -- and at concentrations as much as 24 times greater. "The EPA is doing the bare minimum it can and that's putting people's health at risk," said Kyla Bennett, policy director at the advocacy group Public Employees for Environmental Responsibility.
"PFAS are a class of chemicals used since the 1950s to make thousands of products repel water, stains and heat," notes the Guardian. "They are often called 'forever chemicals' because they don't fully break down, accumulating in the environment, humans and animals. Some are toxic at very low levels and have been linked to cancer, birth defects, kidney disease, liver problems, decreased immunity and other serious health issues."

"[W]hen it comes to identifying PFAS-contaminated water, the limitations of the test used by state and federal regulators, which is called the EPA 537 method, virtually guarantees regulators will never have a full picture of contamination levels as industry churns out new compounds much faster than researchers can develop the science to measure them," adds the report. "That creates even more incentive for industry to shift away from older compounds: if chemical companies produce newer PFAS, regulators won't be able to find the pollution."

    If tap water is safe to drink, then the bottled water industry will lose a lot of business...

    On the other hand, as long as enough people *think* that tap water is not safe to drink, then the bottled water industry basically becomes a tax upon every American, and the industry would have lots more money for campaign contributions...

    Um.... what should the EPA do? Decisions, decisions....

      "Bottled Water" can also included regular tap water that has been either filtered or subjected to Ozonation and sold as "Purified Water". Water does NOT have to come from a spring or well to be sold as Bottled Water.

      For example, Dasani is sold as "Purified Water" but many people buy it thinking it is somehow better than common filtered tap water.

          Dude, if the EPA was in the pocket of "big bottled water" for donations, they would have skipped right to the part where they are the ones that say the water isn't safe.

          The other interested party in water safety is all the industries that cause the pollution, and the governments that could be liable for giving people unsafe drinking water, and the EPA's lack of funding for being able to detect these new pollutants. (Per the article it's a bunch of new PFAS that the EPA's testing doesn't cover).

          But upon seeing all this you say that the EPA hasn't responded to a day old news article, it must be because they're waiting for a bribe from Evon.

          > What made no sense is Americans continue to waste tax dollars on maintaining potable tap water quality while at the same time drink only bottled water.
          Only drinking bottled water?! You think Americans ONLY drink bottled water and therefore maintaining drinkable water is a waste of tax?

          I'm sorry that you've been polite during this discussion and I'm losing my cool, but so much of society is making the insane reach for the opposite of what a reasonable interpretation of the facts say and it's maddening.

      And yet, most of the bottled water people buy is just tap water. It's bottled from the same municipal supply the tap water comes from.

      There are a few brands that aren't, you might known ones like Evian, and Perrier which are bottled in France and exported, and likewise command higher prices.

      The rest of it is pretty much unregulated - a lot of it just tap water unadulterated. Sometimes it's sent through some filtration. Sometimes it's water untreated from the same reservoirs and called "spring water".

      The bottled water industry will survive - the profits are immense because you can produce cases of bottled water for pennies - 90%+ margins are typical

        The brand I buy for emergencies doesn't get its water from my city's water supply. I've been to 10+ states and can tell the difference in tap water. Some tap water is better tasting than others. My city's water is so hard I try not to drink it without filtering it first.

This filter removes chlorine, VOCs, etc. RO can reduce water hardness by removing dissolved solids. I should have been more explicit in my comment.

      Around here the tap water is safe to drink, it's just really horrible. Tastes bad, destroys all your appliances because it's so hard. You either buy bottled or a filter, and even then your appliances get wrecked by it. You clothes can never be cleaned properly, can't take a decent shower.

      I know, first world problems, but the point I am getting to is that water is so cheap that there isn't much incentive to even fix leaks, let alone make sure it's good quality.

Sure, but not all. So when the article is comparing ppt numbers between a general test like TOF and the specific PFAS tests and concluding "OMFG, the levels are X times higher than we thought!", it's simply wrong. You have to also do the work to show what interferences to the TOF test show up that aren't PFAS and test for those as well, and I'm sure there are some.

The state has been in major legal actions [nhpr.org] against some PFAS manufacturers. Local advocacy groups, such as in Portsmouth, are riding on this hard. And the state's regulations for PFAS [natlawreview.com] levels in drinking water are substantially more stringent than the EPA's.
