Evaluating the Longevity and Hydraulic Performance of Permeable Reactive Barriers at Department of Defense Sites

Abstract

The longevity and hydraulic performance of several permeable reactive barriers (PRB) were evaluated using a variety of conventional and innovative tools. Accelerated long-term column tests simulating the changes in reactivity of granular iron barriers at two Department of Defense (DoD) sites showed reductions in trichloroethylene (TCE) degradation rate by factors of between two and four, upon exposure to 1,300 pore volumes of groundwater. Precipitation of certain dissolved solids from the groundwater was found to be the main cause of reactivity loss.
