Project Title: Permeable reactive barriers designed to mitigate eutrophication alter bacterial community composition and aquifer redox conditions
Principal Investigator(s): Hiller, K.A., Foreman, K.H., Weisman, D., & Bowen, J.L.
Summary: Permeable reactive barriers (PRBs) consist of a labile carbon source that is positioned to intercept nitrate-laden groundwater to prevent eutrophication. Decomposition of carbon in the PRB drives groundwater anoxic, fostering microbial denitrification. Such PRBs are an ideal habitat to examine microbial community structure under high-nitrate, carbon-replete conditions in coastal aquifers. We examined a PRB installed at the Waquoit Bay National Estuarine Research Reserve in Falmouth, MA.
