Abstract: Denitrification in wetlands is useful for removing nitrate from the surface water, although it can be difficult to assess wetland functioning particularly where it overlies a hard-rock aquifer whose fractures and joints form pathways that mix waters with different chemical composition. The variability of NO3 concentrations in such waters, which partly transit through wetlands, can obscure the effect of denitrification. To address this question, we monitored groundwater chemistry at different depths on three pi…
