The context to this is the EPA's toxicity assessment on PFAS chemicals ("forever chemicals"), which are a family of chemicals shown to stay in the environment and human body for extremely long periods of time. Under the Trump administration, the EPA's toxicity assessment on PFAS essentially provided polluters leniency on how much they could release. Consequently, these chemicals are showing up in significant numbers in drinking water & food. Since they are proven to have damaging effects on human health, this assessment is now being reevaluated. The lesson from all this is that depending on where you are and how you use tap water, the regulations might not line up with what's good for you. Use a water filter.
