The results of a recent bench-scale test confirmed the effectiveness of a special blend of CL Solutions’ microbes formulated for PAH bioremediation. The test results showed that after two weeks, the total concentration of 15 PAH compounds decreased by 85% from a total of 358 mg/kg to 50.9 mg/kg. Benzo(A)pyrene is often a most difficult PAH to remove. The test showed that the custom blend reduced the benzo(A)pyrene concentration from 24.5 mg/kg to 3.68 mg/kg. Tests will continue to determine whether even greater effectiveness can be achieved over 30 days.
Petrox microbes provide quick response surface oil spill bioremediation. Petrox can be applied to the oil surface with a backpack sprayer to initiate rapid bioremediation. This approach protects surface water and vegetation with minimal surface traffic.
In the following example, an oil spill affected the vegetation and surface water at the edge of a lake. Contractors applied Petrox to the oil surface on vegetation and soil. Periodic soil samples tracked the results. After 90 days, the maximum and average concentrations decreased by more than 95% at a very low cost.

Petrox bioremediation is used to remove petroleum contamination from soil and water under many different conditions. From surface spills to deep soil and ground water contamination, Petrox has successfully removed the contamination and environmental risk. This summary of case studies demonstrates the applicability of Petrox bioremediation to the full range and life cycle of petroleum spills. Click here to view the document.
Petrox bioremediation of surface spills and TPH accumulation in drainage ditches and maintenance areas is simple. Using a simple manual sprayer, the Petrox is applied to the soil surface. The Petrox microbes begin bioremediation immediately to enhance natural digestion of the petroleum, like probiotics for petroleum destruction. Unlike detergents that wash the visible oil deeper in the soil, Petrox microbes destroy the all of the oil.
The following chart and table show the results of the application of Petrox to petroleum-contaminated soil in a drainage ditch. After about 60 days, the TPH concentration was reduced by 67% in one location and over 90% in three locations. A second application to the 30 ft. north area reduced the concentration even more.
The problem was solved for a total Petrox cost of $600.
