Case Study: Dry Cleaners Site, Southern California Site Summary CL-Out® fast dry cleaner bioremediation cost-effectively removed solvents from soil and ground water at a site in Soutern California. After one application of CL-Out® bioremediation, the total chlorinated solvents concentration in ground water decreased by 90%. At the same time, the contaminant concentrations in soil decreased […]
Site Summary A CL-Out bioaugmentation pilot study verified the applicability of CL-Out remediation of an industrial dry cleaning site. The pilot study also determined whether the availability of oxygen to support cometabolism would limit the bioremediations. Geology and Hydrology Although the impacted ground water was relatively shallow, the site geology was complicated and varied across […]
Compatable Techology To Finish Remediation CL-Out® micorbes bioremediation of chlorobenzene continued treatment after ISCO remediation stalled. The target isomers included chlorobenzene, 1,3-dichlorobenzene, 1,4-dichlorobenzene, and 1,2-dichlorobenzene. Before bioaugmentation, individual concentrations exceeded 50,000 µg/L. The CL-Out® treatment quickly reduced contaminant concentrations by as much as 82% more. Remediation Approach and Results Injection through temporary well points introduced […]
