Klozur® Used in Ex Situ Remediation of PCE and TCE In Soils

The ex-situ chemical oxidation technology was implemented to reduce levels of PCE and TCE to below site-specific treatment standards.

Contaminants Treated

Perchloroethylene (PCE), trichloroethylene (TCE)


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.
