Short summary
In this study, the influence of surface water–groundwater interaction on the nutrient flux in a lowland karst catchment in western Ireland was investigated with the aid of alkalinity sampling and a hydrological model. Results indicated that denitrification within a number of ephemeral lakes is the main process reducing nitrogen concentrations within the turloughs, whereas phosphorus loss is thought to occur mostly via sedimentation and subsequent soil deposition.
