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 with 50 pounds of dextrose to provide a carbon source to support the energy requirements of the population. The post-treatment sample was taken after the monitoring well was purged of the injected volume.
The pilot study verified the applicability of CL-Out bioremediation to the site. The total concentration of CVOCs was reduced from 59,000 to 13,740 µg/L.
