  • Petrox Bioremediation of Oil Pipeline Leak

    Petrox bioremediation was used to treat unrefined oil that leaked from a pipeline in Texas.  The oil migrated from the impacted soil into ground water and seeped into the surface water in a nearby river.  After one application of Petrox, the oil concentrations in ground water at the source decreased from 600ppm to less than 100 ppm.  Two more treatments reduced the ...
