The 125-acre Saltville Waste Disposal Ponds site is located in Saltville, Virginia. Olin Corporation's Saltville chlorine gas plant operated at the site from 1895 to 1972. Olin Corporation disposed of wastes generated by the plant in two on-site disposal areas, Pond 5 and Pond 6. Waste disposal operations contaminated soil, sediment, surface water and groundwater and caused contaminant accumulation in fish in the North Fork Holston River. Groundwater treatment and additional investigations are ongoing.
