ScienceGroundwater is the water that soaks into the ground from rain and can be stored beneath the ground. An aquifer is a body of rock and/or sediment that holds groundwater. There are two main types of aquifer in Ireland – bedrock aquifers, and sand and gravel aquifers. Bedrock is...

There are more than 1,200 geological formations and members (rock units) in the 1:100,000 Bedrock Geology map. Rock properties such as colour, grain size and type, origin, fossil and mineral content are used to define formations and members. A lot of these properties are not...

ScienceGroup Water Schemes (GWSs) are community-run water supply schemes. About 70% of GWSs take their water from a privately-sourced supply. The rest take their water from an Irish Water connection (DHPLG, 2017). 81% of the privately-sourced supplies affiliated to the National...

Public Water Supplies (PWSs) are managed by Irish Water, Ireland's national water utility, since 2013. Before this, public water supplies were managed by Local Authorities. More than 70% of public supplies take groundwater from boreholes, springs and infiltration galleries....

The Groundwater Vulnerability map shows land areas across Ireland where groundwater can be easily polluted. It also shows areas where it is well protected by the subsoil layers. The vulnerability category given to a site or an area is based on how easy it is for water which...

Subsoil is the layer of soil under the topsoil and on top of the bedrock. The ease with which water can pass through the subsoil is known as the ‘permeability’. The subsoil permeability affects how easily rainwater can soak down into the ground and fill up the groundwater...
