Chemetco, Inc

The copper smelter Chemetco operated nearby 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 ended following the detection by EPA inspectors of a secret hazardous waste pipe in September 1996. The location, just south of Hartford near the community of Mitchell, was listed as a Superfund priority cleanup site March 4, 2010.

Notable people

Hartford is the birthplace of actor Clint Walker, known for the television series Cheyenne and for the movies The Ten Commandments and The Dirty Dozen.
