TimpeallachtGravity is the measure of the force of attraction at any point on the Earth's surface. This force will vary depending on the rock type present. Gravity data is used for interpreting sub-seabed geology often in the context of the hydrocarbon exploration and mining...

A borehole is any hole drilled or dug into the ground. The hole is usually deep, narrow and round. The material (soil and or rock) from the hole is collected and tested in a laboratory to find out the structure and type of the soil and or rock beneath the ground. A borehole...

Bedrock is the solid rock at or below the land surface. Over much of Ireland, the bedrock is covered by materials such as soil and gravel. The Bedrock map shows what the land surface of the North East, Midlands, Cork and Dublin would be made up of if these materials were...

Groundwater is the water stored below ground in tiny cracks in the rock or in very small spaces between sand grains. It comes from rainwater that soaks into the ground into an aquifer. An aquifer is a body of rock and/or sediment that holds groundwater. The process of rain...

EolaíochtWater 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...

EolaíochtDifferent 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...

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.

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...

EolaíochtGroundwater sources, particularly public, group scheme and industrial supplies, are of critical importance in many regions. The Group Scheme Preliminary Source Protection Areas dataset comprises Zones of Contribution to groundwater abstraction points that supply Group Water...

Groundwater sources, particularly public, group scheme and industrial supplies, are of critical importance in many regions. The Public Supply Source Protection Areas dataset comprises Source Protection Areas (SPAs) around groundwater abstraction points that are managed by...

The groundwater vulnerability concept is based largely on the question “can water and contaminants move in the subsurface materials (soil and subsoil) and/get down to groundwater easily?” Groundwater is most at risk where the subsoils are absent or thin and in areas of karstic...

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...

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 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.

EolaíochtThe survey data combines data from a number of different surveys into one merged dataset. The individual surveys consist of; (1) Tellus Northern Ireland 2005-2006 (2) Cavan-Monaghan, 2006 (3) Tellus Border, 2011-2012 (4) Tellus North Midlands, 2014-2015 (5) Block A1, 2015 (6)...

Before building new structures engineering companies carry out a site investigation to find out the quality of the ground (strength and depth of soil and to see if rock and or groundwater is present). These investigations involve digging holes such as trial pits and boreholes....
