CL#8 - In Situ BioLogix Application - Case Study
Site Information Delta Remediation was contracted to remove trichloroethylene (TCE) from deeper 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. Prior to treatment, a small area of soil less than 500 square feet had TCE concentrations greater than 20,000 μg/L. The underlying impacted ...

PCE Aerobic Bioremediation by Key-Hole Source Removal
CL-Out aerobic PCE bioremediation in a keyhole treatmentreduced the mass of contamination near the source and down gradient concentrations in the plume. At a former manufacturing facility in Ohio the concentration of PCE near the source was over 100,000 ug/L. Down gradient of the source the PCE concentrations were less than 10% of the source concentration. Aggressive treatment in the source ...

Chlorinated VOC Groundwater & Soil Remediation - Case Study
Summary Burns & McDonnell was retained to perform soil and groundwater remediation of chlorinated volatile organic compounds (VOCs) such as perchloroethylene and trichloroethylene (PCE and TCE) at a warehouse facility in Dallas. A historical spill of the chlorinated VOCs behind the warehouse building resulted in the contamination of soil in the immediate area and shallow groundwater leading ...

Incorporating site-specific analytical data and machine learning to predict environmental site conditions
EnviMetric makes intelligent predictions about the extent of groundwater contamination even when there is no available analytical data regarding contaminant concentrations. Factors such as the site location, release type, property use, and geologic setting are very predictive of how large a groundwater plume will be. EnviMetric uses all this available information to make data-based predictions ...
