Such a headline surely suggests that the definition of 'unsafe' needs clarification, since we are not all dead.

Such a headline surely suggests that the definition of 'unsafe' needs clarification, since we are not all dead.
- alistairSH 3y agoUnsafe doesn’t have to mean immediately fatal. The dangers of PFAS are pretty well known - hormone disruption, cancers, reduced vaccine efficacy.
- anymouse123456 3y agoTo your point, from the article: "I'm not super concerned about the everyday exposure in mountain or stream water or in the food. We can't escape it... we're just going to have to live with it." I agree that it doesn't feel right to read a quote like, "I'm not super concerned about..." along with such a dire sounding headline.
- Lendal 3y agoBecause we don't drink rainwater.
- bamboozled 3y agoWhat are we drinking then ?
- Gasp0de 3y agoGroundwater, water from wells.
- gambiting 3y agoIn a lot of places drinking water is pumped from open air aquifiers(a lake basically) so presumably it contains everything rain does, since it doesn't go through the rock layers.
- shantara 3y agoWhich is also polluted with pesticides and other agricultural pollutants.
- defrost 3y agoNot all wells, mainly those that are in aquafier catchments that include heavy PFA sites and agricultural runoffs, etc. Airports are notorious sources, PFA's were used in fire fighting foams for a decade or more (depending on global location).
- lm28469 3y agoSpring water or water coming from water treatment plants, both of them are very dissimilar to rain water
- kwhitefoot 3y agoAll of which ultimately comes from rainwater.
- lm28469 3y agoOf course, and most of it comes from sea water, it doesn't mean you can drink sea water
- belorn 3y agoUltimately all water comes from the creation of the earth, which in turn got it from space. The ultimate origin is not very useful. If we just want the first step before treatment plants, it depend on location. Generally it is what ever water that is cleanest and cheapest, usually lakes and rivers with the best connection and high flow of ground water. Ground water tend to be highly filtered which lowers the amount of treatment that treatment plants has to do. Rainwater collection is usually not used for drinking water given the high amount of pollution. It can be used in industry/agriculture, or as backup for areas where the ground water is severely limited.
- PeterisP 3y agoThere is a substantial level of natural filtration between rainwater and springwater, so they are not equivalent.
- phyzome 3y agoIn the Boston area, our water comes from the Quabbin Reservoir. That's largely fed by rain, as far as I am aware. How much PFAS actually gets filtered out? Probably not much.
- lulzury 3y agoYou can actually easily find this information online [0] > PFAS compounds, used since the 1940s for many purposes, from stain and waterproofing to firefighting, continue to be a concern. Tests of MWRA water show only trace amounts of these compounds, too small to be quantified, and well below the state standard of 20 parts per trillion. MWRA results are also well below recently proposed EPA standards.

- timeon 3y agoWe don't but are we alone on this planet?
- stubish 3y agoA lot of the world most certainly does, especially in rural areas that are not connected to water treatment plants. Bore water tends to be hard, so humans stick to the rain water when we can get it.
- lm28469 3y agoNot dead but you have 50% of the testosterone of your great grandpa due to environmental pollution and other factors
- Filligree 3y ago[flagged]
- lm28469 3y agoAll I know is that we're rapidly changing things that have been much more stable for thousands and thousands of years. Getting rid of aggressivity is good but if it takes your fertility/strength/bone density/dementia resistance/&c. with it... but then again is humanity a good thing ?
- r3d0c 3y agonothing to do with testosterone but emotional intelligence
- hackerlight 3y agoTestosterone doesn't directly cause aggression, it causes people to compete which may manifest as aggression if aggression leads to status in whatever culture you live in. - my recollection of Robert Sapolsky
- Neil44 3y agoCitation needed
- a_gnostic 3y agoLook bruh, we have the documents, and they're turning the frogs gay.
- Izkata 3y agoHe was reading an article about how chemicals we're dumping are triggering a frog species natural ability to change sex. The frogs normally do it when there's too many of one sex, to even it out, but the chemicals were making them switch when there was balance and were causing an imbalance. Truth is stranger than fiction: it would have been more accurate for him to say "they're turning the frogs trans".
