Title: rainwater unsafe to drink worldwide
Post by: billy rubin on August 12, 2022, 05:24:26 PM
QuoteA compilation of the data since 2010 that his team studied showed that "even in Antarctica or the Tibetan plateau, the levels in the rainwater are above the drinking water guidelines that the US EPA (Environmental Protection Agency) proposed", he said.

so they say. i remem er travelling through colorado many yrars ago and discovering that all tbe pristine mountain streams miles into the wilderness back country were contaminated with heavy metals- chromium, molybdenum, lead . . .

the reason is that every valley has an abandoned 19th century mine at its upper end, and every abandonded mine has a pile of contaminated spoil in front of it.

looks like precip is following the same pattern

Bur that's polyfluoroalkyl substances, not heavy metals. Doesn't ruin your point. There is research into processes than can break these chemicals back down into their constituents, with some success.

That makes for rather depressing reading.

Well... If you have to, you can drink rainwater, but should filter and probably boil it first.

It's more or less common knowledge that dehumidifier water is unsafe for consumption, after all, and rain is... Pretty much that, only natural.

just a parallel

pure as the driven snow no longer appliez in the same manner as pure as mountain streams

the lesson is that there is no longer a safe haven to which we could theoretically retreat. the exposure is inescapeable
