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 ground water treatment. The PCE remediation did not cause an increase in vinyl chloride showing that the breakdown pathway […]
The Massachusetts Department of Environmental Protection awarded Irwin Engineering of Natick, Massachusetts the 2016 Greener Cleanup Leadership Award for the innovative in situ bioremediation of perchorate contamination of soil and ground water at the Concord Road Site in Billerica, Massachusetts. The award honors LSPs and their clients for promoting greener cleanup principles and practices to […]
CL-Out microbes using aerobic bioremediation can remove PCE contamination from ground water. One of the easiest ways to remove a large mass of residual PCE from ground water is to treat the ground water following source soil excavation. Because CL-Out microbes cometabolize PCE under aerobic conditions, the microbes can be applied to the ground water […]
Bioaugmentation results can be accelerated and amplified by soil mixing to improve distribution and contact. The equipment shown in this example was used to blend Petrox with contaminated soil to a depth of 10 feet. Click here to view a short video of soil mixing.
CL-Out makes bioremediation by cometabolism of 1,1,1-TCA and other chemicals in a mixed solvent plume possible. One of the benefits of CL-Out cometabolism is that the enzymes produced by the Pseudomonas sp. organisms convert a wide range of organic chemicals into organic acids that can be metabolized. The aggressive application of CL-Out organisms to soil […]
