Perchloroethylene (PCE), trichloroethylene (TCE)

SITUATIONAL SUMMARY

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.  

RESULTS

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.
