Contaminants Treated

Benzene

SITUATIONAL SUMMARY

Benzene from impacted soils had persisted between 320 μg/L and 264 μg/L. Injections were implemented utilizing a combination of Klozur® oxidant and proprietary catalyst solution, in conjunction with Subterranean Hydrocarbon Oxidation Circulation (SHOC) in-situ delivery techniques.

RESULTS

Benzene mass was reduced from pre-injection baseline levels of 276 μg/L to a sustained level of below 5 μg/L. Concentration levels currently remain below laboratory detection limits.
