COMBINING GEOCHEMICAL AND NUMERICAL MODELING FOR CHLORINATED SOLVENTS GROUNDWATER CONTAMINATION
Chloroethenes represent a serious risk to aquatic ecosystems and human health on a worldwide scale. Chloroethenes contamination is difficult to solve due to the different optimal redox conditions needed to obtain efficient degradation of each chloroethene. The more chlorinated ones such as …

Evaluation of Chitin as an Electron Donor and Nutrient Source for Stimulating the in Situ Bioremediation of Chlorinated Solvents
… injection for the in situ bioremediation of chloroethenes, and raises interesting questions on microbial community structure and motility in groundwater systems.

Investigating the Biostimulating Effects of ESO Addition to a TCE Contaminated Site
… South Carolina. Each microcosm was monitored for chloroethenes, volatile fatty acids, long chain fatty acids, and total carbon on a weekly basis. Results show successful fermentation of fatty acids and reduced conditions favorable for dechlorination.

Ionisation studies of chlorinated and fluorinated compounds
… of the reactions of cations with the three dichloroethenes have been performed to look for evidence of isomeric effects. Major differences are seen when the reactant ion is CF\(_3\)\(^+\); when 1,1-dichloroethene is the neutral reactant the only ionic product is C\(_2\)H\(_2\)Cl\(^+\), but if …

Comparison of Potential Bioavailable Organic Carbon and Microbial Characterization of Two Carbon Amended Sites
Enhanced Reductive Bioremediation (ERB) is a sustainable remediation technology for the in situ treatment of chlorinated solvent contamination in aquifers. However, monitoring efforts employed to measure performance metrics rely on inferences of the subsurface environment from water samples …

Isolation and Ecology of Bacterial Populations Involved in Reductive Dechlorination of Chlorinated Solvents
The findings of this study demonstrate that Dehalococcoides species are intimately involved in complete reductive detoxification of chlorinated ethenes and are widely distributed in anoxic sediments and aquifers, including non-contaminated (pristine) environments. Careful examination of enrichment …

Sustainability of Reductive Dechlorination at Chlorinated Solvent Contaminated Sites: Metrics for Assessing Potentially Bioavailable Natural Organic Carbon in Aquifer Sediments
Groundwater remediation strategies have advanced toward more effective and economical remedial technologies. Monitored natural attenuation (MNA) has become accepted by federal regulatory agencies as a viable remediation strategy for contaminants under site-specific conditions. At chloroethene …
