Abstract:  The Groundwater Vulnerability map shows land areas across Ireland where groundwater can be easily polluted. It also shows areas where it is well protected by the subsoil layers. The vulnerability category given to a site or an area is based on how easy it is for water which may contain pollutants to reach the groundwater. Geologists map and record information on the subsoils above the bedrock. They find out how deep the subsoil is and how permeable it is (how easy water can pass through it).They use information from quarries, deep pits and from boreholes (a deep narrow round hole drilled in the ground). Subsoil depth, type and permeability maps are combined to work out the groundwater vulnerability at that location.Landforms found in the Irish landscape like sinkholes and sinking streams (‘karst’ landforms) are categorised as extremely vulnerable as water can pass straight through.Where the water table is close to the surface in sand and gravel aquifers, groundwater vulnerability is also extremely vulnerable.This Groundwater Vulnerability map is to the scale 1:40,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 400m.It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas). The groundwater vulnerability data are shown as polygons. Each polygon holds information on the vulnerability category (X, E, H, M or L), a description explaining this (‘Extreme – rock at or near surface/karst’, ‘Extreme’, ‘High’, ‘Moderate’ or ‘Low’) and a unique id.

Purpose: Groundwater is the water that soaks into the ground from rain and can be stored beneath the ground. Groundwater is used to supply drinking water and needs to be protected. It is mainly protected by layers of subsoils, sands or peats. The vulnerability map classifies how vulnerable groundwater is to pollution across Ireland, based on its level of protection. Knowing this helps people to plan and carry out activities on the land in a way that keeps our groundwater safe to drink.

Lineage:
Lineage statement: Geologists map and record information on the composition and structure of subsoil types and the composition of these, and information from boreholes (a deep narrow round hole drilled in the ground). Areas are drawn on a map to show the distribution of subsoil types. Originally, in the 1990s, a number of counties had this information drawn by hand on paper maps. These map sheets are available in paper copy accompanied by reports, in GSI. Phase 1: These paper maps covering Ireland were digitised. Each map was manually digitised using AutoCAD 12.0 software. Several layers of data were created for each map sheet: Bedrock outcropping at surface and within 3 m of the surface, Subsoil permeability, and Depth to Bedrock. Linework and Point symbols were stored in .dwg format. The data were registered to the OSi 1:50,000 digital rasters. The data were clipped to the OSi coastline (high water mark). Water bodies such as lakes were also clipped. Irish National Grid (IG) projection. Phase 2: Field data were converted to ArcGIS coverages (2001 to 2008) IG AutoCAD layers were converted to .dxf format and imported into ArcGIS 7.x. Coding was used to attach attribute information to the data layers from the vulnerability table. A legend was generated. The ArcGIS coverages were converted to shapefiles. Phase 3: Field data were converted to ArcGIS coverages (2008 to 2016) IG Data were digitized directly into ArcGIS 8.x. Coding was used to attach attribute information to the data layers from the vulnerability table. A legend was generated. The ArcGIS coverages were converted to shapefiles. Phase 4: ArcGIS shapefiles IG (2016) were re-projected in ArcGIS from Irish National Grid (IG) to Irish transverse Mercator (ITM) projection. A legend was generated and the stylefile updated. Data topology checked. The dataset comprises 1 shapefile. 1) Groundwater Vulnerability ITM_2016.shp - A polygon shapefile that contains groundwater vulnerability information (whether ‘Extreme’, ‘High’, ‘Moderate’ or ‘Low’). Errors noted and recorded in the previous version were corrected. Data topology checked. Phase 5: The Groundwater Vulnerability map data was updated on March 9th 2020. Basemap inputs were updated - Depth to Bedrock, Karst features, Sinking streams, Subsoil permeability and hence the scripts to update the Groundwater Vulnerability map needed to be re-run. Python scripts were developed making best use of the PyQGIS API. In 2021, the data structure was reviewed and a new database was created in ArcGIS Enterprise. Using ArcGIS Pro 2.6.3, the dataset was renamed as part of a GSI data standardisation process. A standardised dataset alias was added. A unique id field was added. A new unique identifier was added for each record using an attribute rule. Most fields were renamed and an alias added. Domains were created for relevant fields to ensure attribute integrity for those fields. The attribute values can only be added from pre-defined GSI tables in the form of drop-down values. Attribute rules were set up to automatically insert certain values eg unique identifier. The data was cleaned using a GSI notebook. This checked the attribute values contained valid domain values and a spell check was carried out. Some manual cleaning of obvious errors was also carried out. Data was simplified (reduction in the number of vertices) using the Simplify polygon in ArcGIS Pro 2.7.1. GSI notebook for data cleaning was re-run. Metadata was updated to new GSI standard.
