Benzo(a)pyrene Bioremediation Using Custom Blend Microbes

Benzo(a)pyrene is a difficult remediation challenge. It is resistant to biological and chemical destruction and extraction from soil.  CL Solutions Custom Blend microbes, however, have successfully remediated benzo(a)pyrene and other PAHs in soil during ex situ land farming treatment.  By placing the contaminated  material in windrows, controlling the temperature and moisture, the addition of Custom […]

Fast Dry Cleaner Remediation

Case Study Demonstrates Fast Dry Cleaner Remediation Bioaugmentation makes fast and cost-effective dry cleaner remediation possible.  Dry cleaning solvents were found in the ground water adjacent to a dry cleaning facility located in a commercial shopping center in Houston, Texas. InControl Technologies, Inc. of Houston, Texas was the environmental consulting firm that completed the site […]

In Situ CL-Out Bioremediation of Industrial Solvents

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 […]

Using Cl-Out to Finish Remediation Following Chemical Oxidation

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 […]

TCE Remediation With CL-Out® Bioremediation and Dual-Phase Extraction

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 […]
