Many times oxygen is injected to improve natural attenuation of petroleum and other contaminants. The results are often less than expected because the beneficial microbes that the oxygen addition is supposed to stimulate are absent or insufficient in numbers. Bioaugmentation has been used to improve the results once the oxygen levels have increased but failed to […]
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. […]
After removal of USTs, ground water was treated over a one-half acre plume in Houston, Texas. Petrox bioaugmentation was implemented by injection of 110 gallons of high concentration microbial solution in April 2006. Post-treatment sampling shows the bioaugmentation significantly reduced the source area contaminant levels at a cost of less than $2,000 for the Petrox®. Sampling Date […]
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, […]
