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 […]
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 […]
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 […]
Case Study: Industrial Site, Houston, Texas Site Summary CL-Out® bioaugmentation was implemented in combination with dual phase extraction at an industrial site near Houston, Texas to remove trichloroethylene (TCE) from ground water. The overlying contaminated soil was excavated, but perched ground water and a deeper aquifer had TCE concentrations greater than 10,000 µg/L. A dual-phase […]
