If you ask me, it’s an ass-backwards system. For the chemical we’re talking about, reports showed in the 1960s that it was causing liver cancer in rabbits and dogs, and it was a contaminant we needed to keep an eye on. But instead of understanding what this chemical was doing in the environment, they set a guideline of 400 parts per trillion.
Then the EPA did a study and took a very long time to reach the conclusion that they finally reached in 2016, which is that this causes liver disease and thyroid cancer and a plethora of other illnesses. But I think these chemicals should be studied before they even get into the marketplace, before they’re ever put into the water system or the public is exposed to them over long periods of time.
