CL-Out® for Aerobic Bioremediation of PCE and other Chlorinated Solvents


Fast, reliable, and cost-effective bioremediation in soil and ground water under natural conditions.

  • CL-Out contains beneficial strains of freeze-dried Pseudomonas organisms selected for their ability to bioremediate PCE and daughter products under aerobic conditions.
  • High quality control measures verify the cell counts and absence of pathogens. CL-Out contains only naturally occurring microbes without genetic engineering involved.
  • Aerobic cometabolism is effective for removing solvents from soil or ground water.
  • Aerobic cometabolism breaks the carbon to carbon bond and does not produce harmful daughter products like vinyl chloride.
  • Can be used as a highly effective stand-alone decontamination solution or to augment chemical treatment, sparging and vapor extraction or pump-and-treat.
  • compatibility with the natural conditions reduces risk of project failure.

Restores Property Value

CL-Out has successfully remediated hundreds of properties, from small dry cleaners in shopping centers, to industrial brownfields and military bases. Aerobic cometabolism saves time and money by working with the natural site conditions and using a high population of known beneficial micorbes.  Site closure often occurs in a matter of weeks or months versus several years or more for other methods, giving users the combined benefit of fast site closure and remarkable cost savings.
