Case Study: Pipeline Leak, West Texas
Petroleum was discovered seeping from a river bank in west Texas. The seepage was traced back to a 8-inch oil pipeline leak approximately 40 feet from the river bank. Investigation of the pipeline leak showed contamination in the soil around the pipeline and the ground water below it. Petrox® was used to treat the soils and ground water at the source to mitigate the seepage. Petrox® bioremediation reduced the contaminant concentrations to acceptable levels in less than one year.
Implementation and Results
Soil Type: Silty sand
Treatment Area: 5,000 sq. ft.
Saturated aquifer thickness: 5 ft.
Treatment: Three applications, initial treatment with 2 units of Petrox® and 2 follow up treatment with 2 units of Petrox® and a calcium peroxide oxygen supplement.
Product Cost: $6,000
Petrox® bioremediation quickly and cost-effectively removed the sheen and reduced the contaminant concentrations to acceptable levels. The metabolism of petroleum requires the presence of oxygen, which was added through the injection of calcium peroxide. Petrox® bioaugmentation accelerated the site remediation and reduced uncertainty by applying the right microbes where they were needed, the calcium peroxide provided the right growth conditions for the beneficial microbes.
