Zone of Contribution delineation Pilot Project

The development by the Geological Survey of Ireland (GSI) of a tool for delineating the zone of contribution (ZOC) to boreholes and springs opened up the possibility of mapping all GWS source catchments. A joint NFGWS/GSI proposal for a groundwater pilot study in Counties Limerick and Cork was adopted by the National Rural Water Services Committee (NRWSC) and won the approval of the Minister. Conducted on 6 group water schemes, this pilot study provided a template for the delineation of all groundwater source ZOCs.
