Cl-Out bioremediation at a dry cleaner in Vermont demonstrated bioremediation of PCE in aerobic ground water. CL-Out microbes were selected for bioremediation of the site because they are compatible with the natural aerobic aquifer conditions. One application of CL-Out bioaugmentation reduced the PCE concentration by 90% in less than 6 months without increasing the vinyl […]
The success of bioaugmentation depends on effective distribution of the beneficial microbes. If the target population is achieved, the remediation rate ranges from 50% to over 99% removal. The rate appears to be independent of the contaminant starting concentrations. This indepedence is the advantage of bioaugmentation. Through bioaugmentation the density of beneficial organisms is sufficient for […]
A CL-Out bioremediation push-pull pilot study was implemented at a confidential dry cleaners site to verify the applicability of CL-Out bioremediation. One unit of CL-Out was injected into the affected ground water in the source area. One unit of CL-Out is a 55-gallon slurry with a microbial concentration of 1,000,000 cfu/ml. The CL-Out microbes were injected […]
By switching from active extraction to in situ CL-Out® bioremediation, In Control Technologies, Inc. of Houston, Texas saved their client $100,000s in on-going operation and maintenance costs. The Site was a shopping center where soil and ground water were contaminated by dry cleaning chemicals. A dual phase extraction system was installed and operated for 9 […]
Aerobic cometabolism of PCE and other halogenated solvents by Pseudomonas sp. has been well established for more than 20 years. The following research articles were key in the development of this approach to bioremediation. This academic research provided parallel support to CL Solutions’ successful application of aerobic cometabolism to bioremediation of hundreds of contaminated sites […]
