Cost-effective Bioremediation of a Dry Cleaners Quickly Removed Contamination Historical operations at a Houston area dry cleaners resulted in a chlorinated solvent plume (perchloroethylene or PCE) in the shallow ground water. Permeable shallow soil at the site allowed rapid vertical migration at the source and lateral migration in the shallow ground water. This migration resulted […]
A brownfield plan included Cl-Out bioremediation to reduce high concentrations of TCE and other contaminants in ground water at an industrial site near Newark, New Jersey. Using a dynamic remediation plan, three applications of CL-Out microbes followed remediation progress sampling during the site preparation for construction. After reducing the maximum CVOC concentrations from over 8,000 […]
With Petrox microbes, in situ TPH bioremediation reduced the concentration of petroleum in soil at a former gas station from 9,500 mg/kg to 52 mg/kg. The impacted soil was at more than 20 feet deep. Injection of calcium peroxide provided the oxygen needed for metabolism of the petroleum by Petrox microbes. The post treatment sampling […]
CL-Out aerobic bioremediation PCE and TCE is a sustainable process for soil and ground water remediation. As these compounds are not directly metabolized under aerobic conditions, the competitive advantage goes to the CL-Out organisms that cometabolize them. While utilizing a sugar substrate, the CL-Out organisms produce mono- and dioxygenase enzymes that bridge the carbon bond […]
Bioremediation used to complete closure CL-Out bioremediation was used to remediate ground water at an active manufacturing plant in eastern Massachusetts after ISCO treatment of TCE in groundwater reached a limit. CL-Out was selected because the aquifer was naturally aerobic. CL-Out cometabolizes TCE and other chlorinated solvents under aerobic conditions by producing an oxygenase enzyme […]
