Case Study: Industrial Site, Houston, Texas Site Summary CL-Out® bioaugmentation was implemented in combination with dual phase extraction at an industrial site near Houston, Texas to remove trichloroethylene (TCE) from 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. A dual-phase […]
A bench-scale study demonstrated the viability of bioremediation of chromium contaminated ground water. The key factor to successful bioremediation was the selection of chromium-tolerant microbes. Actual contaminated ground water samples for the test. The ground water contained total chromium of 280 mg/L, with 270 mg/L hexavalent chromium. The original sample was split into four bottles, […]
Soil Recycling Prepares Site for Redevelopment A 30 acre bulk fuel facility is ready for reuse after on-site bioremediation of nearly 100,000 tons of petroleum-contaminated soil in an urban setting near Los Angeles. Bulldog Green Remediation of Walnut Creek, California used a proprietary ex situ treatment process combining Petrox organisms in a custom blend to […]
CL Solutions recently completed a field pilot study of bioremediation of mixed chlorinated pesticides. Under the pilot study Petrox treated several cubic yards of soil highly contaminated by a suite of related chlorinated organic pesticides. The pilot study showed the overall impact was a reduction of the pesticide concentrations by 28% to 93% in 60 […]
Sulfolane is an emerging contaminant of concern for potential environmental impact to ground water in Alberta. CL Solutions recently completed laboratory bench-scale testing that showed the Petrox organisms can efficiently degrade sulfolane. Under laboratory conditions Petrox organisms metabolized sulfolane at a minimum rate of 33 ug/L/day. Further lab tests are under way and field scale […]
