6 Million Americans Exposed To High Levels of Chemicals In Drinking Water, Says Study (businessinsider.com)

An anonymous reader quotes a report from Business Insider: A new study out Tuesday in the journal Environmental Science and Technology Letters looked at a national database that monitors chemical levels in drinking water and found that 6 million people were being exposed to levels of a certain chemical that exceed what the Environmental Protection Agency considers healthy. The chemicals, known as poly- and perfluoroalkyl substances, or PFASs, are synthetic and resistant to water and oil, which is why they're used in things like pizza boxes and firefighting foam. They're built to withstand the environment. But PFASs also accumulate in people and animals and have been observationally linked to an increased risk of health problems including cancer. And they can't be easily avoided, like with a water filter, for example. You can view the chart to see the tested areas of the U.S. where PFASs exceed 70 ng/L, which is what's considered a healthy lifetime exposure.

    This isn't "dihydrogen monoxide", it's the class of compounds that includes C8, which was used in Teflon manufacture until recently. It never degrades and will last millions of years. It causes birth defects (reduced birth size, physical developmental delays, or miscarriage), cancer, and liver disease.

    Now "chemtrails" *are* bullshit.

    It helps if there is a working link in TFS.

    The contamination areas includes, Southern California, Northern California, Central California, Texas and large swaths of the Eastern United States (from the Great Lakes to Massachusetts) and down the seaboard to Florida. I would say 6 million is a gross underestimation - considering how much produce is shipped outside of California,and the population density in the affected areas.

      From TFA;

      exceed what the Environmental Protection Agency considers healthy.

      Actually, this is not true. What is exceeded is the regulated or recommended limit, which is set lower, usually much lower, than what they consider safe or 'not healthy' from scientific evidence. Now, that doesn't mean we should be OK with the situation, so don't go off getting mad at me for no reason, I'm just pointing out a commonly seen misrepresentation of facts that bugs me.

    no, it punches holes in cell membranes that tar from cigarettes then follows in. Asbestos fibers are much, much larger than DNA strands. Everyone who's gotten cancer from asbestos smoked.

    The commercial bottled water plants which use tap water (Pepsis/Aquafina, Coca Cola/Dasani, etc) use reverse osmosis on the tap water before bottling. Reverse osmosis removes all PFASes.

    It's actually "natural" spring water in affected areas you have to worry about. They can pick up these substances from the environment.

    Guess where all the Pepsi in the USA is made?

    Hmm, I'm going to guess "at regional bottling plants run by different bottling companies who franchise from PepsiCo", because that is in fact how it actually works. There is no one factory which makes the Pepsi for the whole country. Heck, most large metropolitan areas have their own bottling plant which uses the local water, so there's not even usually one source per state.

    Perhaps you've confused your regional Pepsi bottler for the only source of Pepsi in the US because you don't understand what's going on at all.

    That's true, but dioxin (specifically tetrachlorodibenzodioxin) is an organochlorine. Covalent bonds between carbon and chlorine are artificial. In nature chlorine is never found like that; it occurs as an ion or a mineral constituent. PFOAs have covalent bonds between carbon and fluorine, which are also artificial.
