The ex-situ chemical oxidation technology was implemented to reduce levels of PCE and TCE to below site-specific treatment standards.
Soils and groundwater at the subject site had become contaminated with levels of perchloroethylene (PCE) and trichloroethylene (TCE) at concentrations in excess of 20,000 mg/kg and 100 mg/l, respectively. Klozur® was implemented as an on-site ex situ approach to remediate 40,000 tons of contaminated soils containing approximately 32,000 lbs. of CVOCs.
The treatment of the contaminated soils from a site wide average resulted in reduction of contamination levels to less than 5 mg/kg. Two major benefits of applying Klozur® (persulfate technology) included the elimination of PCE and TCE in the soil and on-site re-use of the treated soils as opposed to costly offsite disposal as hazardous waste.
