Aerobic Cometabolism of TCE and 1,4-Dioxane

Field Demonstration of  CL-Out Bioremediation of TCE and 1,4-Dioxane In a pilot study to compare aerobic cometabolism with anaerobic reductive dechlorination  to remediation TCE and 1,4-dioxane at a former industrial facility near Lakewood, New Jersey, aerobic cometabolism reduced the concentrations of both compounds while anaerobic reductive dechlorination was unsuccessful.  For aerobic cometabolism, CL-Out microbes were […]

1,1,1-TCA Bioremediation at an Industrial Site in Dayton, Ohio

Fast, Economical Site Cleanup CL-Out bioremediation reduced the concentration of 1,1,1-TCA in ground water at a steel manufacturing facility in Dayton, Ohio. Following implementation of ozone treatment and high vacuum extraction for more than 2 years, the contaminant concentrations remained high.  Bioaugmentation followed up on these treatments and reduced the 1,1,1-TCA concentration very quickly.  Within […]

CL-Out Bioaugmentation Following ISCO to Remediate TCE

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 […]

Keyhole Source Treatment to Remediate PCE in Ground Water Plume

CL-Out bioremediation was used in a keyhole treatment to remediate PCE.  The source treatment also reduced the mass of contamination down gradient in the plume.  At a former manufacturing facility in Ohio the concentration of PCE near the source was over 100,000 ug/L.  Down gradient of the source the PCE concentrations were less than 10% […]

CL-Out Pilot Study Vandenberg AFB

Successful Aerobic Cometablism A pilot study of the applicability of CL-Out aerobic cometabolism of PCE and other chlorinated solvents was completed at Vandenberg Air Force Base.  The pilot study consisted of injection in a single well and groundwater sampling at four surrounding wells to monitor the progress of bioremediation.  During the pilot study, samples were […]
