Dry Cleaning Site Remediation Miami, Florida - Case Study
Project Summary Dry cleaning solvents were found in the ground water at a shopping center at the former location of a dry cleaning facility at commercial shopping center. Most of the mass of ground water contamination was located under a bank built that was built over the former dry cleaners, which restricted access for remediation. BioLogix CL® bioremediation was implemented to reduce the ...

In Situ Chemical Oxidation Remediation Pilot Study Of A Karst Bedrock Aquifer Contaminated With Chlorinated Solvents
ABSTRACT A pilot study to evaluate an innovative in situ treatment technology was implemented at Letterkenny Army Depot, Chambersburg, Pennsylvania, for a limestone bedrock aquifer contaminated with chlorinated solvents. This technology destroys VOCs in groundwater, utilizing a network of injection points to deliver a solution of hydrogen peroxide (50%), catalysts, and surfactants. The ...

Bioremediation Following Dual Phase Extraction Saves Hundreds of Thousands of Dollars
CL-Out® bioremediation was implemented at a dry cleaners site in Houston, Texas to reduce concentrations of residual PCE and other chlorinated solvents in groundwater following dual phase vacuum extraction. After application of CL-Out® bioremediation the chlorinated solvent concentrations were reduced by 98% to 99% in less than 90 days. The switch saved their client hundreds of ...

Case study - Paint mixing
Overview A company involved in the automotive aftermarket had a paint batch mixing and filling operation that used primers and fillers. They were faced with installing air pollution control equipment to handle the volatile organic compounds (VOCs) emitted by the solvents used in their processes. An independent consultant had determined that total exhaust volume from the facility was 28,000 SCFM ...

Andover Case Study (C3 Technology)
In this case study in Andover, Vapor Extraction and Refrigerated Condensation was used as a primary source removal technology to remediate high concentrations of recalcitrant chlorinated solvent compounds at the WDE Site in Minnesota. The use of Refrigerated Condensation has achieved high mass removal rates and will reduce the lifecycle costs and time of remediation. Over 6500 drums of hazardous ...

Standard Chlorine of Delaware Remediation
By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

Concurrent bioremediation of perchlorate and 1,1,1-trichloroethane in an emulsified oil barrier
Abstract A detailed field pilot test was conducted to evaluate the use of edible oil emulsions for enhanced in situ biodegradation of perchlorate and chlorinated solvents in groundwater. Edible oil substrate (EOS®) was injected into a line of ten direct push injection wells over a 2-day period to form a 15-m-long biologically active permeable reactive barrier (bio-barrier). Field monitoring ...

Bioaugmentation to Treat Chlorinated Solvents in Fractured Bedrock
ABSTRACT: An in situ bioremediation pilot study was performed at a former industrial site in New Jersey where groundwater has been impacted by historical releases of chlorinated solvents. The target area for treatment is a fractured, intermediate bedrock zone. The remedial objective at the Site is to treat the groundwater while minimizing the impact of the remedial system on the re-development of ...
