Harmonized vulnerability to pollution mapping of the upper aquifer: DRASTIC map – Rockingham Pilot Area (IRELAND)

This is a groundwater vulnerability map of the Rockingham Catchment, based on the DRASTIC groundwater vulnerability method. The Rockingham Catchment, is a hydrogeological catchment to Rockingham Spring source and has an area of 16 km2, located in Western Ireland. The 7 DRASTIC input layers are Depth to water table, net Recharge, Aquifer media, Soil media, Topography, Impact of vadose zone and hydraulic Conductivity. These input values are weighted and added together to give an overall DRASTIC score.
