Old mines still plague Montana's Clark Fork

Why one of the nation's largest Superfund river sites can't address pollution from abandoned mines.

Several hundred mines burrowed beneath the city, and in 1908, a flood washed tons of contaminated sediments from those mines into the river. Arsenic, copper, zinc, lead and cadmium contaminated millions of tons of sediment along 120 miles of the river’s banks — all the way to Missoula. The river’s legendary but struggling trout all but vanished.
