Permeable Reactive Barriers (PRB)

This page includes planning documents and demonstration test results for Permeable Reactive Barriers (PRBs), a passive treatment technology designed in this application to intercept and treat nitrate in groundwater before it reaches downgradient surface waters. PRB demonstration projects will provide data to assess the effectiveness and applicability of PRBs as a supplementing alternative technology for the Town to cost-effectively reach water quality goals.
