  1. [This](https://www.culligan.com/support/water-information/what-are-pfas-pfoa-and-pfos) is one of approx 2000 man made chemicals developed over the decades that are loosely classified as [forever chemicals](https://www.nbcnews.com/politics/politics-news/can-epa-get-rid-toxic-forever-chemicals-n1281707). Chemicals that do no bio-degrade, break down in sunlight, UV etc and are not affected by oxygen and other elements and conditions they might be exposed to. Not all are as toxic as this one, but many others are, and some are air born as well, giving them a global reach in some cases.

  2. From the EPA.

    “Scientific studies have shown that exposure to some PFAS in the environment may be linked to harmful health effects in humans and animals.”

    It is NOT deemed toxic. It is considered potentially harmful. Big difference.

    Don’t take Wikipedia as authoritative. It is edited by people with an agenda.
