Review of Reactive Material Suitable for the Construction of the PRB Wall
The longevity of PRBs denote their ability to sustain their function (hydraulic capture, residence time, and reactivity) in the years and decades following
installation. It is strongly dependent on the groundwater chemistry and flow
rates, and contaminant concentrations at the remediation site. The observed
mineral phases at different PRB sites are controlled by the groundwater constituents that naturally vary depending on the biogeochemical setting of the
site (Roehl et  al., 2005a). PRBs require a much better understanding of site
