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...

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...

This data represents a seamless bedrock geological dataset encompassing Rep of Ireland and parts of Northern Ireland derived from 1:500,000 scale data. This map presents the bedrock data from the OneGeology-Europe map project (www.onegeology-europe.org) coloured to an Irish...
-
This dataset contains a coverage for all mapped and digitised glacial trimline (ice free)areas, which were not glaciated during the last glaciation, for the island of Ireland. The map forms part of the GSI Quaternary Map series. Data recorded on the maps includes the locations...
