Enhanced Bioremediation of TPH with IXPER® case study
This remediation has been conducted after removing of leaking underground storage tanks from a former gasoline service station in Bethalto, Illinois, and limited source area excavation and air-site disposal of petroleum-contaminated soils. Dissolved petroleum constituents in excess of state reguatory standards were still observed in the groundwater. It was estimated that the remaining ...

In-situ Aerobic Bioremediation of Recalcitrant Organics: A Case Study Demonstrating Benefits and Potential Limitations
Abstract A history of spills and/or releases at two adjacent dry cleaning facilties in the Houston, Texas area resulted in significant soil and shallow ground-water contamination. The soils at the adjacent properties (collectively called 'the Site') are relatively permeable allowing for rappid vertical migration at the source area(s) and lateral migration in the shallow ground water. The ...

Compatible Technologies to Improve In-Situ Remediation of Chlorinated Solvents: A Case Study
Abstract: A chlorinated solvent plume (perchloroethylene or PCE) was discovered in the shallow ground water as a result of historical operating practices surrounding a Houston area dry cleaning facility. Permeable shallow soil at the site allowed rapid vertical migration at the source and lateral migration in the shallow ground water. This migration resulted in an off-site migration of the plume ...

Waterloo Emitters used for Bioremediation Study in High Temperature Saline Groundwater
A study was undertaken to determine the success for aerobic bioremediation of aromatic hydrocarbons (BTEX) and MTBE (methyl tert-butyl ether) in high temperature, saline groundwater conditions. The study included laboratory microcosm experiments, as well as a field trial in Saudi Arabia, in which Solinst Waterloo Emitters were used. To view the full paper published about this study, please visit ...

HD#6 - In-Situ BioLogix Application - Case Study
Site Summary After the removal of a leaking tank and the surrounding impacted soils, BioLogix microbes were used to treat soils adjacent to a storm sewer pipe contaminated with residual petroleum constituents. The site soils were silty clay fill, formed from excavated and recompacted native tills during the sewer installation. The soil was moist, but the treatment was above the ground water ...

Enhanced Bioremediation
Introduction Enhanced bioremediation is a process in which indigenous or inoculated micro-organisms (e.g., fungi, bacteria, and other microbes) degrade (metabolize) organic contaminants found in soil and/or ground water, converting them to innocuous end products. Nutrients, oxygen, or other amendments may be used to enhance bioremediation and contaminant desorption from subsurface materials. ...
