Petrox has been used for the bioremediation of surface spills and TPH accumulation in drainage ditches and maintenance areas. Using a simple manual sprayer, the Petrox is applied to the soil surface. The Petrox microbes begin bioremediation immediately.
The following chart shows the results of the application of 10 gallons of Petrox to petroleum-contaminanted 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. The Petrox cost to treat 2,000 square feet was $200.
