They are attributed with aquifer descriptions and include summary statistics of physical and chemical properties of each aquifer. This data accompanies the ‘Northern Ireland’s Groundwater Environment’ book which can be accessed at https://nora.nerc.ac.uk/id/eprint/535562/. This provides information on how the aquifers were defined and delineated, aquifer conceptual models and explains the groundwater processes within each aquifer. The GSNI 1:250,000 bedrock and superficial datasets (https://gsni-data.bgs.ac.uk/geonetwork/srv/eng/catalog.search#/metadata/50f02373-cc6e-46f6-b3e2-f05be55b662a) provided the base mapping for these datasets. The aquifer summary statistics have been derived from the Northern Ireland Groundwater Data Repository. This is a database of over 2000 boreholes and springs. An index can be viewed at https://mapapps2.bgs.ac.uk/gsni_geoindex/home.html. These attributes can be used to create bespoke groundwater maps relevant to the application they are being used for.

They show the extent of each of the 11 defined aquifers found in Northern Ireland. They are attributed with aquifer descriptions and include summary statistics on the aquifer physical and chemical properties. They accompany the ‘Northern Ireland’s Groundwater Environment’ book which can be accessed at https://nora.nerc.ac.uk/id/eprint/535562/. This provides information on how the aquifers were defined and delineated, aquifer conceptual models and explains the groundwater processes within each aquifer. The GSNI 1:250,000 bedrock and superficial geology data provide the geometry from which these data have been generated for these datasets. The aquifer summary statistics have been derived from the Northern Ireland Groundwater Data Repository. This is a database of over 2000 boreholes and springs. An index can be viewed at https://mapapps2.bgs.ac.uk/gsni_geoindex/home.html. These attributes can be used to create bespoke groundwater maps relevant to the application they are being used for. All other aquifer description attributes have been derived using a combination of available information and expert judgement by BGS Hydrogeologists.
