DPT Injection – Chlorinated VOC’s

ORIN successfully treated PCE contaminated soil and groundwater utilizing In-situ chemical bioremediation during the pilot scale injection. Six injection points were advanced using DPT throughout the treatment area. Each point was located approximately 16.5 feet apart to ensure complete coverage of the targeted treatment area. The vertical treatment zone extended from 50 feet below ground surface (ft bgs) to 25 ft bgs. ORIN injected a 5% concentration of EOS treatment chemistry into the injection points to enhance the naturally occurring reductive dechlorination of chlorinated solvents. Each injection point received approximately 1,325 gallons of treatment chemistry. A total of 7,950 gallons of 5% EOS treatment chemistry was injected into the six injection locations.
