Cl-Out bioremediation reduced high concentrations of TCE and daughter compounds in ground water at an industrial site near Newark, New Jersey to meet an aggressive redevelopment schedule. 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 ug/L to less than 20 ug/L, the site met the remediation goals and received a No Further Action Letter from NJDEP.

Delta Remediation of Acheson, Alberta, Canada is featured in the Canadian Trade Commissioner Service as a leader in clean technologies for the oil and gas industry in Canada and internationally. Delta Remediation uses a proprietary blend of CL Solutions’ organisms called Biologix for bioremediaion of hydrocarbons in soil, water and ground water.

Petrox reduced the concentration of TPH 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 was 90 days after the bioaugmentation, so that even though the average remediation rate was 105 mg/kg/day, the peak remediation rate must have been much higher when the Petrox population was higher.
This is another example of fast, reliable bioremediation by Petrox organisms.
Creosote bioremediation was recently demonstrated by a user of a custom blend of CL Solutions organisms. The environmental consulting firm applied the microbes to finely shredded wood that had been saturated with creosote. The initial testing results after bioaugmentation showed a reduction of the creosote concentration by 57% in just 7 days. The concentration measured as total recoverable hydrocarbons decreased from 3,453 mg/kg to 1,497 mg/kg.
Convenience Store in Florida
After three underground storage tanks were removed from the location of a convenience store, investigation showed that petroleum contamination was present in small area near the former dispenser island. The vadose-zone contaminated soil was excavation and disposed off-site. Ground water monitoring showed that the ground water impact was limited to a small area near the source of contamination. The decision was made to close the site by applying Petrox® bioremediation to the ground water.
Ground Water Contamination
The ground water contamination was in a shallow water table aquifer that had a medium permeability. The contamination was a suite of BTEX, PAHs, methylnaphthalene isomers and TRPH.
A pilot study was completed to determine feasibility of Petrox bioremediation combined with a peroxide oxygen supplement. The pilot study reduced contaminant concentrations by up to 92%. A full-scale application completed the site remediation.
The pilot study and full-scale applications of Petrox and an oxygen supplement reduced BTEX compounds by >99%, naphthalene by 99%, TRPH by 96% and naphthalene isomers by 88% to achieve the remediation goals and site closure. The microbial cost for the pilot study and full-scale treatment was less than $2,000.
