Most of these I knew about, but not #GrassyNarrows

"Grassy Narrows mercury contamination (1960s)

For nearly a decade, the Dryden Mill’s chloralkali plant discharged up to 24,000 pounds of mercury into the #WabigoonRiver. It is regarded as one of the worst cases of industrial pollution in Canada’s history. Many people in the Grassy Narrows #FirstNation and #Whitedog First Nation communities were poisoned due to the contamination."
