HydrologyIn-situ chemical oxidation (ISCO) is a common method to remediate chlorinated ethene contaminants in groundwater. Monitoring the effectiveness of ISCO can be hindered because of insufficient observations to assess oxidant delivery.

Process-based modeling of electrokinetic-enhanced bioremediation of chlorinated ethenes
Journal of Hazardous Materials, 2020 This study presents a process-based modeling analysis of electrokinetic-enhanced bioremediation (EK-Bio) to illuminate the complex interactions between physical, electrostatic and biogeochemical processes occurring during the application of this remediation technique.

Reductive Dechlorination of Chlorinated Ethenes at the Sulfidated Zero-Valent Iron Surface: A Mechanistic DFT Study. [PDF]
J Phys Chem C Nanomater InterfacesSulfidated nano- and microscale zero-valent iron (S-(n)ZVI) has shown enhanced selectivity and reactive lifetime in the degradation of chlorinated ethenes (CEs) compared to pristine (n)ZVI.

Modeling Chlorine Isotope Trends during Sequential Transformation of Chlorinated Ethenes [PDF]
Environmental Science & Technology, 2009 There is increasing interest in combined carbon-chlorine compound-specific isotope analysis (CSIA)to differentiate between contaminant sources and to assess transformation processes. However, the significant abundance of polychlorinated molecules with several heavy chlorine isotopes complicates the evaluation of chlorine isotope trends.

Application of in situ chemical oxidation technique with potassium permanganate for the remediation of a shallow aquifer contaminated with chlorinated solvents [PDF]
Geologia USP. Série Científica, 2012 In situ chemical oxidation is a method that is frequently being used for the remediation of contaminated areas, since it presents an adequate efficiency in the reduction of the contaminant mass, particularly chlorinated ethenes, in a relatively short ...
