Interactions Between Biological and Abiotic Pathways in the Reduction of Chlorinated Solvents

John T. Wilson While biologically mediated reductive dechlorination continues to be a significant focus of chlorinated solvent remediation, there has been an increased interest in abiotic reductive processes for the remediation of chlorinated solvents. In situ chemical reduction (ISCR) uses zero-valent iron (ZVI)–based technologies, such as nanoscale iron and bimetallic ZVI, as well as naturall...

Source Reduction of Chlorinated Solvents in Electronics Industry

Chlorinated solvents are a class of interrelated chemicals that have gone through major regulatory scrutiny in recent years. A number of chlorinated solvents are used in the electronics industry in printed circuit board (PCB) fabrication and assembly; semiconductor wafer fabrication and assembly; and critical cleaning applications. The growth in the electronics industry in the last few decades ...

Fuzzy Systems Modeling of In Situ Bioremediation of Chlorinated Solvents

The full-scale in situ bioremediation demonstration conducted at DOE’s Savannah River Site revealed a wide range of spatial and temporal variations of concentrations of VOCs, enzymes, and biomass in groundwater and vadose zone monitoring boreholes over the field site. One of the powerful modern approaches to analyze uncertain and imprecise data is based on the use of methods of fuzzy systems mo...
