Design and construction techniques for permeable reactive barriers.
Adequate site characterization, bench-scale column testing, and hydrogeologic modeling formed the basis for the design and construction of permeable reactive barriers for groundwater remediation at various sites, such as Dover Air Force Base, DE and Naval Air Station, Moffett Field, CA. Dissolved chlorinated solvents, such as perchloroethylene (PCE) and trichloroethylene (TCE), have been the focus at many sites because the passive nature of the reactive barrier operation makes such barriers particularly useful for treating groundwater contaminants that can persist in the aquifer for several years. A combination of conventional and innovative site characterization, design, and construction techniques were used at these sites to increase the potential cost effectiveness of field application.
