Abstract

Intensification of agriculture in areas with underlying fractured bedrock aquifers poses a challenge to the sustainable management of soils and water resources. The EU Water Framework Directive (WFD) attempts to achieve at least "good ecological status" for all water bodies by 2015. In Ireland and many other EU countries eutrophication due to nutrient enrichment is a major cause of poor status. The objective of the current preliminary study, conducted at a dairy research farm in the south of Ireland, was to estimate nitrate mass discharge in a fractured limestone aquifer. Direct discharge measurements were conducted to assess flow rates and nitrate discharge of karstic springs. A stream tube model was developed to assess the nitrate discharge in the fractured aquifer. The developed model estimated that up to 18 tons nitrate per year were being discharged from groundwater to the nearby river, which equates to 54% of the current total agronomic nitrate load on the farm.
