and we've collected enough arsenic from a single mine to kill every human on the planet 300 times over in one spot- what's your point? That because we screwed up one spot we should give up?

Whoa; TIL. It's terrifying the number of future-time-bombs we keep planting for ourselves.

if you're interested, theres several documentaries on the canadian government's efforts to keep it contained. I think Tom Scott's shortish one was my starting point.

Not sure why people buried your post, but many water-soluble metal salts are pretty toxic to animals and people.

In areas with natural Arsenic accumulation (or Acid rain run off), farmers will sometimes place rusting iron equipment in the water ways to reduce metals accumulating in the topsoil.

With low rainfall the evaporated well-water problem can certainly be a serious concern. =3

Hoes does this work and related to the arsenic and acid rain?

Would have preferred a better source, but likely a similar process to the following:

Best of luck =3

I think it's probably because- even with a trivially verifyable source- the 300x lethal dose for 9 billion people is a knee jerk "no way!"
