Permanently remove vapor intrusion risk Soil bioremediation is a more effective strategy for managing the vapor intrusion risk at dry cleaners where solvents have contaminated soil or shallow ground water. Soil bioremediation quickly eliminates the problem, while long-term vapor mitigation ties up resources in on-going operation, maintenance and monitoring costs. Soil bioremediation eliminates the source […]
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 […]
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 […]
Aerobic cometabolism of TCE may be limited by the potential microbial toxicity of by products or by product metabolic repression. An independent comparison of induced cometabolism using soluble methane and CL-Out bioaugmentation showed that CL-Out bioaugmentation removed more TCE. The TCE removal rate by CL-Out when supplemented with an oxygen source was a steady rate […]
When a source of ground water contamination or contaminant vapors is present under a building, efforts to mitigate the spread of contamination may continue indefinitely with mounting costs. Bioremediation may be used to remove the source of vapors or ground water contamination without damage to the building or interrupting operations. There are many examples of […]
