Case Study : Industrial Manufacturing Site, Illinois Remediation Summary Leaks from an aboveground solvent tank impacted soil and ground water quality at a manufacturing site in Illinois. The impact was found under the adjoining building as well as the area near the tank. The soil and ground water were treated in situ with CL-Out® bioremediation […]
Project Summary Degreasing solvents were found in the ground water at an industrial manufacturing facility in Tampa, Florida. The solvents include PCE and its associated breakdown products. The source of the ground water contaminants was found to be a former water treatment system drain field. CL-Out® bioremediation was implemented to reduce the volume of contamination […]
CL-Out was used to complete the remediation of ground water contaminated by chlorinated solvents from a former dry cleaning site in Rockville, Maryland. The ground water contamination had migrated from leaking sewer lines to underlying bedrock fractures. Fenton’s Reagent was first applied to the site, but the PCE concentrations increased due to desorption. Subsequently, sodium […]
The US EPA Technology and Field Services Division produced a report on aerobic cometabolism of chlorinated solvents under their Contaminated Sites Clean-Up Information program on February 7, 2019. This report includes an overview of aerobic cometabolism and guidance on application and monitoring. Click here to link to the report. While the report cites the research […]
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 […]
