A national database of boreholes including locational and stratigraphic information. Boreholes must have a grid coordinate for every entry. Boreholes known to open file and boreholes unrecorded in open file are included, particularly boreholes drilled by the GSI. A number of...

The Quaternary geology of Ireland – Sediments Map is a representation of the surficial geology of Ireland at a scale of 1 to 50,000. The map shows the sediments mapped within 1 metre of the surface which were laid down during the Quaternary, bedrock at or close to the surface...

This dataset was generated as part of the Geological Mapping programme’s 1:50k re-mapping compilation. This dataset is built on the existing Bedrock Borehole Locations dataset with numerous corrections of the entries and a compilation of previously uncaptured drillholes....
-
This database contains records of boreholes, dug wells, springs, and site investigations. Data are derived from GSI drilling, fieldwork and surveys, Local Authorities and other state bodies, Private Well Grants, Drillers, Consultants, Group Water Schemes and Academia. It is...

Water tracing involves tagging water to see where it goes. The time the tracers take to get from one point to the other is also usually recorded. It is most commonly used in karst environments to ascertain groundwater flow rates, directions and catchment definitions (Zone of...
-
The Groundwater Subsoil Permeability map classifies how easy water can infiltrate subsoils downwards at any point in the land surface. Permeability across the country is classified as either ‘High’, ‘Moderate’ or ‘Low’. This map is used to determine groundwater vulnerability...
-
This Hydrostratigraphic Rock Unit Groups map is a reclassification of the 1:100,000 bedrock geology map, created by grouping bedrock formations and members into 27 Rock Unit Group categories based on their hydrogeological properties and other factors.
-
Two Source Protection Areas (SPAs) are delineated. The Inner Protection Area (SI), designed to protect against the effects of human activities that might have an immediate effect on the source and, in particular, against microbial pollution. The Outer Protection Area (SO),...

Different aquifers have differing abilities to store and transmit water. Based on the hydrogeological characteristics and on the value of the groundwater resource, GSI has classified Ireland’s land surface into aquifer categories. GSI Aquifer classes are divided into three...

The national Groundwater Recharge Map depicts estimated recharge to the deep groundwater system, i.e. groundwater that can be tapped as the sustainable resource. The main hydrogeological controls on groundwater recharge include subsoil permeability, subsoil thickness,...
-
A collection of internal and external reports and papers with an associated access database. Groundwater Protection Schemes Reports available for: Cavan, Clare, South Cork, Donegal, Kerry, Kildare, Kilkenny, Laois, Limerick, Meath, Monaghan, Offaly, Roscommon, Tipperary North...
-
Karst is a landscape with distinctive landforms that develop on rock types that are readily dissolved by water. In Ireland, karstification mostly occurs in limestone regions. This karst dataset contains mapped karst landforms in Ireland including: boreholes, caves, dry...

The Quaternary geology of Ireland – Sediments Map is a representation of the surficial geology of Ireland at a scale of 1 to 50,000.
-
This dataset is the GSI’s legacy borehole database, compiled over many years from many sources. This dataset is available while we make significant improvements to our borehole holdings.
-
The verified drill holes dataset is a cartographic representation of the collar coordinates of Geological Survey Ireland drill holes combined with a new compilation of historical mineral exploration holes from the Open File system.
