Like global warming, endocrine disruptors have been a concern for decades in the scientific literature. Most microplastics would fall in this category. They're hard to filter out of the water supply. There isn't any way to treat this once they have been ingested, and the bioaccumulation for fat soluble molecules is pretty high.
Now the Guardian article that came out this week reporting 128/130 city water supplies tested in the USA show heavy metal contamination, given that lead is neurotoxin at all detectable levels, is a much simpler topic. There is absolutely no excuse for detectable levels of lead being present in nearly all (>99%) of the tested samples.
Wtf??
Edit: I've been fucked by lead comrades
Turns out we're more like the boomers than we care to admit
Link to that Guardian article? Thanks.

Depending on the instrument involved, "detectable" can be extremely low. They probably meant "unsafe levels"?
The EPA action level for lead is 15 µg/L (parts per billion). By comparison, an ICP-MS can detect lead at 0.0005 µg/L. That's thirty thousand times lower!
theres no safe level of lead tho, afaik
Which is why exposure should be minimized, but total elimination is impossible. It's like ionizing radiation. You will be able to detect lead in even the cleanest sources.
Unsafe was just a descriptor I used for unacceptably high.
Bio-accumulation is a bitch though, does lead bio-accumulate?
