Chemetco, Inc

The former copper smelter, Chemetco, operated here for around 30 years ending in 2001. The corporation was found guilty of Clean Water Act offenses after its sustained pollution of Long Lake, a tributary of the Mississippi River, over a ten-year period. This only ended after the detection by EPA inspectors of a secret hazardous waste pipe in September 1996. This site is not technically located within the village limits of Hartford, but south of town, near the community of Mitchell.
