Bioremediation of Dinitrotoluene

Dinitrotoluene (DNT) may occur in soil and ground water as the result of spills and historical use of the chemical as a solvent and industrial intermediary or as a residual of explosives at military facilities.  CL Solutions and SpecPro, Inc. conducted a treatability study to determine the effectiveness of CL-Out microbes in the removal of […]

Push-Pull Application of Aerobic Cometabolism

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 […]

CL-Out Bioaugmentation Saves Time and Money

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 […]

Research on Aerobic Cometabolism of PCE

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 […]

TCE Aerobic Cometabolism Using Cl-Out

CL-Out bioaugmentation was used to reduce the TCE concentrations in ground water at an industrial site in Louisville, Kentucky.  CL-Out microbes were injected into the TCE-contaminated ground water.  Dextrose was added to provide the carbon source for the microbial growth.  An oxygen supplement was necessary to maintain aerobic conditions in the aquifer. Ground water sampling downgradient […]
