A superfund site.
Republic Steel Quarry (RSQ) is a five-acre water containing quarry surrounded by seven acres of fenced land. Waste pickle liquor and rinse water made up of sulfuric acid and dissolved metal oxides were discharged daily from 1950 to 1975. The selected cleanup plan resulted in the removal of sediment and soils from a drainage ditch and contaminated areas around the edge of the quarry. Cleanup also included ground water monitoring, fish identification, and site restrictions.
