17. Assessing nutrient enrichment risk to groundwater-dependent ecosystems in the border counties of Ireland

Geological heterogeneity across the border counties of Ireland leads to variable levels of resilience in groundwater-dependent ecosystems (GWDEs). In a review of 26 catchments, with contrasting land-use and geology, we investigated the roles that soil and subsoil geochemistry may play in protecting GWDEs against nutrient enrichment from external sources. While the Tellus soil geochemical data sets…
