Superfund Site Profile
The Cherokee County Site is a former mining area in southeast Kansas, part of a larger regional mining area known as the Tri-State Mining District. It covers about 115 square miles. Over 100 years of widespread lead and zinc mining created piles of mine tailings covering more than 4,000 acres. The mine tailings contaminated groundwater with lead, zinc and cadmium. Following cleanup, operation and maintenance activities and monitoring are ongoing.
