Naphthalene Bioremediation Is No Problem For Petrox

Petrox microbe thrive on naphthalene and are very efficient at naphthalene bioremediation in the field. In fact, naphthalene is occasionally  used in the QA/QC  process to verify Petrox viability and effectiveness.  In this test, the Petrox organisms are placed on an agar devoid of a carbon source.  The naphthalene is applied to the top plate as the sole carbon source.  The Petrox viability is then demonstrated by colony growth on the top plate as shown on the following picture.

CL-Out Bioremediation Meets Aggressive Brownfield Redevelopment Plan

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.

Aerobic Cometabolism of Chlorinated Solvents, Central New Jersey Case Study

CL-Out® was successfully used to remediate solvents in ground water at an operating industrial site in central New Jersey.  The the facility was a manufacturing and plating company with historical petroleum and solvent releases.

Chlorinated solvents were found in the ground water in two plumes covering a combined area of about one half acre.  The contaminants were a mix of chlorinated solvents including 1,1,1-TCA, 1,1-DCE and PCE in low concentrations.    The remediation goal was to reduce the mass of contamination in the ground water plume to prevent mitigate off-site risks.

After the CL-Out application, ground water concentrations in all monitoring wells decreased by more than 80%, which was sufficient to meet the remediation standards.  Click here to download a complete case study.

Fast Creosote Bioremediation Results

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.

CL-Out Bioaugmentation Following ISCO to Remediate TCE

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 that breaks the carbon to carbon bond.  Under aerobic conditions daughter products such as DCE and vinyl chloride are not formed.  30 days after one application of CL-Out the TCE concentration was reduced by 97% and the site remediation goals were achieved.
