Biotechnology of hydrocarbon bioremediation in soil washing slurry
Application of Bioremediation for low cost contaminated soil washing slurry treatment with quick hydrocarbon reduction and improved sustainability. The application uses proprietary microbial formulation with a slurry bioreactor in order to accelerate the degradation process and to make it compatible with soil washing technology. The end result is a treated soil which meets the requirements for ...

Refinery remediation: fuel recovery and recycling
Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

Surfactant desorption is key to successful PAH bioremediation
Formulations which are patented non-ionic surfactant mixtures used in the in situ and ex situ treatment of petroleum hydrocarbons, chlorinated solvents, heavy metals, and more recently PAHs, PCBs and MTBE type contaminated waste are involved in Surfactant Enhanced Bioremediation (SEB®) using Iveysol ®. These surfactant formulations have the ability to enhance soil biodegradation. During in ...

STAR (In Situ) Pilot Test for the Treatment of Petroleum Hydrocarbon-Impacted Soils - Former Waste Oil Refinery, Chia-Yi, Taiwan - Case Study
Overview The subject site is a former waste oil refinery located in a mixed use industrial, commercial, and residential area of Chia-Yi, Taiwan. Petroleum hydrocarbon impacts are present in a fine silty sand layer from approximately 5 to 5.8 meters below ground surface (m bgs). This target treatment zone is overlain by a silty clay layer extending to near ground surface. A STAR Pre-Design ...

EPA Technology News & Trends - Tacoma “Well 12A” Superfund Site
The U.S. EPA Region 10 office uses an adaptive site management approach that relies on high-resolution site characterization (HRSC) techniques for strategic sampling at the Well 12A project area. This approximate one-square-mile project area is one of three at the 2.5-square-mile Commencement Bay-South Tacoma Channel Superfund site in Tacoma, Washington. The vicinity of Well 12A, one of 13 wells ...
