Dryden

The town came onto the national consciousness in the early 1970s when natives at the community of Grassy Narrows became sick with Minamata disease (mercury poisoning). Investigation determined that a chloralkali plant located at the Dryden mill was the source of the mercury in the Wabigoon and English rivers. http://en.wikipedia.org/wiki/Dryden,_Ontario
