PCE Bioremediation in Aerobic Groundwater

CL-Out microbes were used to remediate PCE in ground water at a former printing company in Kentucky.  The ground-water stratigraphically was in an alluvial sand deposit with high permeability to facilitate the injection.  The high permeability of the aquifer matrix also supported aerobic ground water conditions.  With one application of CL-Out the concentration of PCE decreased from 3,600 ug/L to 250 ug/L in less than 45 days.  With further applications the concentration was reduced to below detection limits in 10 months.
