Southern California Gasoline UST Release Site After removal of USTs, piping and surrounding soils, ground water was treated with 110 gallons of Petrox® by direct injection in December 2009. Post-treatment sampling shows that the bioaugmentation reduced the contaminant levels to below regulatory standards by the next semi-annual sampling round. Sampling Date TPHg Benzene Toluene Ethylbenzene […]
The following applications demonstrate the significant results that can be achieved with a single application of Petrox bioremediation. Florida Panhandle Gas Station Facility ID # 32-8520334 Petrox was injected through horizontal drilling to address a ground water plume with limited surface access. After a single Petrox® application there was significant reduction in the contaminant concentrations. […]
Petrox bioremediation of oil surface spills reduces TPH accumulation in drainage ditches and maintenance areas. Using a simple manual sprayer, Petrox microbes applied to the soil surface 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, […]
Background High concentrations of petroleum in the subsurface can accumulate in a separate liquid phase that floats on the water table, which is referred to as light non-aqueous phase liquid (LNAPL). Investigation and characterization of the extent of separate phase petroleum is challenging. In turn, successful remediation, which depends on accurate and complete site characterization, […]
