Epa Moves to Roll Back Drinking Water Standards

Last I checked the Federal government does not manage private wells. There are exempt under the Clean Water Act.

Chlorine needs to stay in city water to disinfect all the distribution pipes throughout a city. But at point of use, you should not be drinking/bathing in chlorine or chlorine disinfection byproducts.

The whole MAHA (Make America Healthy Again) movement is an absolutely brilliant masterstroke by corporate interests. Get people up in arms about pseudoscientific bogeymen like artificial dies. Then claim as a major win how you've gotten big food companies to pinky promise that they'll stop using these dyes in Fruit Loops and sodas in a few years - because of course we'll all be super healthy once we're downing naturally dyed Fruit Loops and soda. Meanwhile, gut environmental regulations that actually do have a measurable positive impact on health, make healthcare even more unaffordable, and kick lots of people off Medicaid so rich people can get a tax break. But hey, at least you'll be the beacon of health since you can now gobble your fries cooked in lard instead of those naughty seed oils.

Well, them and Canadian Indigenous reserves lol. But those have been described as 3rd world anyways.

And of those that don't it's mostly because their water is supplied by a well in an area where the groundwater has minerals that affect smell/taste and it's cheaper to buy bottled than to filter them.
