CL-Out bioremediation continued to show outstanding results in bioremediation of PCE, TCE and other chlorinated solvents at three recent applications. Results show more than 90% PCE removal with a single application of CL-Out for in situ soil or ground water treatment. The PCE remediation did not cause an increase in vinyl chloride showing that the breakdown pathway was by dioxygenase cometabolism and not by reductive dechlorination.
A site in Massachusetts showed the following ground water results:
PCE 1,100 ug/L reduced to 30 ug/L
TCE 39 ug/L reduced to 5.6 ug/L
No other daughter products were detected.
Ground water remediation in Florida showed these results:
PCE 182 ug/L reduced to 16.1 ug/L
TCE 9.823 ug/L reduced to 2.77 ug/L
cis DCE 3.26 ug/L reduced to 0.282 ug/L
vinyl chloride was not detected before or after bioremediation.
Soil contamination at a site in New Jersey followed the same trend:
PCE 690 ug/L reduced to less than 5 ug/L
TCE 7,980 ug/L reduced to less than 810 ug/L
No breakdown products were detected.
These sites join the hundreds of sites remediated by CL-Out aerobic cometabolism.
