Wastes were either incinerated or neutralized and disposed on-site. When the facility was shut down by Ohio EPA in 1981 because of poor operating practices and repeated permit violations, more than 10,000 drums and several hundred thousand gallons of bulk liquids were on-site. The results of site investigations showed contamination of on-site soil and groundwater. The Reading well field was shut down in 1994 partially due to contamination from Pristine. The site is being addressed through Federal, State, and potentially responsible parties' actions.
Cleanup efforts consist of four phases.
Thermal desorption of 13,000 tons of contaminated soil was completed in May 1994. The groundwater pump and treatment system was constructed in two phases. The soil vapor extraction system is expected to operate for about 10 years and the ground water pump and treatment system is expected to operate for about 30 years. Discharge from the treatment plant was subject to interim discharge limits for the first two years of plant operation to allow for adjustments to be made to the treatment system for the purpose of minimizing discharge concentrations. Final limits were issued to the Pristine Trust in May 2000.
