Old toxic mining waste along the Coeur d’Alene River kills at least 150 a year-
Toxic marshes deadly to swans: Coeur d’Alene River laden with lead from Silver Valley mining. By Spokesman-Review in the Seattle Times.
This is not really a new story in the sense that it happens every year. I knew that in years past a local conservation group used to have a sarcastic “Dead Swan Days.” The mining waste from a hundred years of silver mines and smelting along the South and main fork of the Coeur d’Alene constitute perhaps the largest Supefund toxic cleanup site in the Unites States. The EPA has been working on it for about 25 years.
