IE GSI Groundwater Vulnerability 40k Ireland (ROI) ITM WMS

Groundwater is the water that soaks into the ground from rain and can be stored beneath the ground. Groundwater is used to supply drinking water and needs to be protected. It is mainly protected by layers of subsoils, sands or peats. The vulnerability map classifies how vulnerable groundwater is to pollution across Ireland, based on its level of protection. Knowing this helps people to plan and carry out activities on the land in a way that keeps our groundwater safe to drink.
