Groundwater Body Descriptions

Groundwater bodies are subdivisions of large geographical areas of aquifers so that they can be effectively managed in order to protect the groundwater and linked surface waters.

Groundwater Protection Scheme Reports

A Groundwater Protection Scheme provides guidelines for the planning and licensing authorities in carrying out their functions, and a framework to assist in decision-making on the location, nature and control of developments and activities in order to protect groundwater. Groundwater Protection Schemes are county-based projects that are undertaken jointly between the GSI and the respective Local Authority. The reports summarise the hydrogeology, aquifers, groundwater vulnerability and the groundwater use in a county at the time of the study.  Groundwater Water Quality Reports  give an overview of the main water quality issues in each county at the time of reporting. Please note N/A indicates Not Available.

Further details are available from the Groundwater Protection Schemes report published by the Department of the Environment and Local Government, Environmental Protection Agency and Geological Survey of Ireland and the dedicated page in the Groundwater programme.
