    Was just in the news here in Norway that a local study[1] of 300 boys found a overall positive correlation between the total amount of the majority of PFAS species and delayed onset of puberty. Overall the effect was around a 1 year delay between those that had were in the lowest PFAS group and those that were in the highest PFAS group.

    Though if I interpreted it correctly, certain specific PFAS species had a negative correlation, so it could swing both ways depending on the mix of PFAS species one accumulated.

      The cost of this remediation nationwide is going to be brutal.

      > By the EPA’s standards, Anaheim’s remaining wells are now considered contaminated. Lyster says the city will expand its PFAS treatment capacity to comply with the federal rule by 2029. All told, building PFAS filtration for all 19 of Anaheim’s wells is projected to cost $200 million.

      > Anaheim and Yorba Linda are part of the Orange County Water District — a public agency that manages the region’s groundwater and which helped to design, fund and build the PFAS filtration plants. Across Orange County, more than 100 wells have exceeded the EPA’s new standards. Fixing the problem in the county is expected to cost $1.8 billion dollars over 30 years, according to OCWD.

        "$1.8 billion dollars over 30 years" in a county of 3mm [1] is about $20 per person per year. Scaled nationally, that implies a cost of about $6bn a year, which sounds amply doable.

          Other resources seem to agree with me with regards to unaffordability at this scale. Maybe we’re just arguing the scale of “a few tens of billions here and there.”

          > PFAS can be bought for $50 - $1,000 per pound (according to MPCA estimates), but costs between $2.7 million and $18 million per pound to remove and destroy from municipal wastewater, depending on facility size.

            $18 million per well. 16 million wells in the United States. So that’s $288 trillion dollars, which is about 1000% of US GDP — ten years of GDP assuming all other spending halts.

              A few tens of billions really isn't a big deal...

              It's kind of funny that you are like an enthusonaut when it comes to businesses and other private entities doing things and then can't imagine that pretty much the only thing government needs to do whatever is the political will.

              • toomuchtodo 2 hours ago

                I can be optimistic about things that don’t matter, but pessimistic when it comes to basic human needs and the historical pattern of people being poisoned by companies without recourse or government not holding polluters accountable. Will it get cleaned up eventually? Maybe. Will it be expensive? Absolutely. Will people be harmed and die in the meantime from PFAS contaminated water. Also true.

                The Inflation Reduction Act demonstrates your point about political will, but it still requires will, and once done, the policy and fiat takes time to have outcomes come out of the machine.

                Nuance!

                  The damage and solution are both local. That reduces the minimum scale of action, which makes organising easier. It also makes benefits personal: you aren't paying $1.60 a month so someone across the world breathes easier or isn't flooded, you're paying so your family doesn't drink PFAS. And you get that benefit if your town or county agree they don't want to be poisoned; you don't need to worry about what Arizona or West Virginia are doing.

                  • llamaimperative an hour ago

                    No, drinking water is only one source of PFAS poisoning. Other sources include food packaging, cosmetics, cookware, paints, cooking oils, and more.

                      Still local and locally controllable. Totally different coordination problem from e.g. emissions reduction.

                    Pfas levels in the US are far below where they were in 2000. We are making solid progress.

            • llamaimperative an hour ago

              Are you talking federal intervention? Because half our governing system (you can guess which) just thinks that water suppliers shouldn't be saddled with the responsibility of ensuring water is clean.

              But yeah maybe municipalities can pull it together piece by piece. Not that that'd help all the other countless sources of PFAS and similar, though.

                I know I'm in a red state instantly by the fact that tap water will taste like sewage.

                Straight off the air-plane in Orlando, I knew instantly that my Disney world trip was going to be miserable and full of over priced bottled water purchases.

                Meanwhile, I can go to any blue state big city in the country. Seattle, Portland, SF bay area, Chicago, New York, and I can great clean clear good tasting water to drink straight out of the tap.

                They really are a basket of deplorables

                • 124816 35 minutes ago

                  You're comparing water taken from the Floridian aquifer (lots of minerals like sulphur, which isn't known for tasting great) with Seattle (water from the mountains), SF (hetch hetchy), etc. I just want to suggest that maybe the taste of water is one of the things that cannot be naively mapped to a linearized space of red vs blue.

                  • trescenzi an hour ago

                    I use a brita water bottle for places with gross water. Actually use it in Orlando regularly. It usually takes most of the swamp taste out but even it cannot fix the horrid water at Cosmic Ray’s.

                I hope PFA manufacturers will have to help pay for this. Especially if they know about the dangers. Makes no sense for them to keep all the profits while the state pays for the remediation.

                • mrweiner 2 hours ago

                  I wonder if the costs associated with this will go down over time. Either way, your first link says 7500 sites are affected, so that’s something like $135 billion if we go off of the Orange County cost? Sheesh. Or is that multiplication not how it works?

                • Neywiny 2 hours ago

                  I highly recommend Dark Waters (it's on Netflix in the US as of a few days ago). It covers a lot of PFAS history and politics in the US. It also finally convinced someone I know to stop thinking it's fine to eat teflon flakes and stop scratching up the nonstick.

                        There area lot of potential things in your water to worry about. Ro gets a lot more out than carbon filters. At a previous house I had lab results to show my well water needed that. most of you have safe water

                      What about fluoridation? They still putting rat poison in the water?

                        Fluoride naturally occurs in groundwater at levels in excess of not only what we add to water but to levels we consider unsafe [1]. Humans have been consuming water with some level of fluoride in it for thousands of years; animals, millions. PFAS, meanwhile, are entirely anthropogenic.

                        [1] https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6572649/

                        • llamaimperative an hour ago

                          Yes because, like the available science says that PFAS are dangerous, the available science says that fluoride is not (at the levels its used).

                          Hope that helps!
