Client Testimonial: Oregon Site

“Our client needed an in situ remedy that could selectively remove TCE from groundwater in the presence of hydrocarbon DNAPL. Bench trials demonstrated that EHC outperformed other technologies (emulsified oil and lactate-based). The subsequent pilot tests included creating a bioaugmented EHC permeable reactive barrier at depths ranging from 50 to 130 feet below ground, using traditional direct-push equipment. Five months following injection, the concentrations of TCE were reduced from approximately 100,000 ppb to below method reporting limits with sustained, negative redox conditions, and no accumulation of catabolites. Because of the relative cost, ease of implementation, and safety of the product, we expect to recommend future installations of EHC at this and many other sites.”
