PCE, 1,1,1-TCA and 1,1-DCE Bioremediation at a New Jersey Manufacturing and Plating Company - Case Study
Background CL-Out bioremediation successfully restored aquifer conditions at an operating industrial site in central New Jersey. The cleanup goal was to reduce the contaminant mass sufficiently to meet site-specific goals to prevent offsite migration ...
Using CoBupH MG to adjust aquifer pH - Case Study
Problem A US Government site had elevated TCE. Low aquifer pH stalled in situ bioremediation. Project Goal Inject organic substrate in the aquifer to enable naturally-occuring bacteria to effect in situ anaerobic reductive dechlorination Control pH to sustain long-term performance Achieve regulatory remediation levels of 5 µg/L TCE in groundwater and 53 µg/kg TCE in soil ...
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 ...
Using AquaBupH to adjust aquifer PH: ESTCP-funded project at Charleston Naval weapons station - Case Study
Elevated levels of trichloroethene (TCE) were found in groundwater at a Department of De-fense (DoD) facility in Charleston, SC. Under an ESTCP-funded in situ technology demonstra-tion project , the Navy had been effectively remediating contamination until a drop in aquifer pH caused dechlorination rates to decline. Solutions-IES responded with a study and applica-tion of buffered substrate to ...
DOD evaluates bioaugmentation for remediating low-pH aquifers
The US Department of Defense (DOD) has completed pilot-scale work on the 'MAG-1' site at Fort Dix, NJ, to test suitability of anaerobic bioremediation for an aquifer with low pH. Project results will be used to design full-scale ground-water treatment at MAG-1. In addition, technical criteria gained from the demonstration will be integrated into DOD’s remediation strategy for its many facilities ...
