The data consists of: Scanned Capture of 450,000 pages and maps, including all of GSI principal datasets, (Mineral Exploration Reports-Open File, Geotechnical Reports, boreholes & tests, Historic 6":1 mile and 1":1 mile Geological Maps, GSI Publications, Bulletins, Published and Unpublished Reports, Groundwater Well Hydrographs, Marine Maps, Airborne Geophysical Maps, Mineral Locality Reports and Mine Record Reports and Maps).

The GEMAS dataset is based on low density geochemical sampling of agriculture (Ap) and grassland (Gr) soils across 34 European countries. Sample density covering an area of 5.6 million km2 of 1 site each, arable land (0-20 cm) and land under permanent grass cover (0-10 cm), per 2500 km2. The Geochemical Mapping of Agricultural and Grazing Land Soil comprises more than 70 chemical elements and parameters determined on more than 4000 soil samples. The geochemistry of European agriculture and grazing soils are depicted graphically on maps of the GEMAS geochemical atlas.

In 2016 the Geological Survey of Ireland as a European partner contributes to GEMAS and EGDI (European Geological Data Infrastructure) with provision of a GIS spatial data classification and publication of WMS geochemical web mapping services to support European data interoperability of EGDI web portal.

The GIS GEMAS sample classification were constructed in ArcGIS 10.1 and the original GEMAS dataset is available as ESRI shapefile format.

A well is a hole dug into the ground usually for the purpose of taking water from the ground but also for monitoring groundwater. Most private wells are used for home and farm water supplies are in rural areas. Springs occur where groundwater comes out at the surface. A borehole is a hole drilled into the ground to gain access to groundwater. The hole is usually deep, narrow and round. This map shows the location of the dug wells, springs and boreholes in Ireland. Data was collected by GSI drilling or submitted to the GSI from Local Authorities and other state bodies, Private Well Grants, Drillers, Consultants, Group Water Schemes and Academia. The location accuracy is visually portrayed on the GSI webmapping viewer by the size of the circle displaying the record. It is NOT a comprehensive database and many wells and springs are not included in this database. You should not rely only on this database, and should undertake your own site study for wells in the area of interest if needed.This map is to the scale 1:100,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 1km.It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).The data is shown as polygons. Each polygon holds information on the location of the borehole (X and Y coordinates), Well ID (well identifier), hole details, location details, yield, abstraction ,drilling details.

Public Water Supplies (PWSs) are managed by Irish Water, Ireland's national water utility, since 2013. Before this, public water supplies were managed by Local Authorities. More than 70% of public supplies take groundwater from boreholes, springs and infiltration galleries. This accounts for about 23% by volume (Irish Water, 2018).Source Protection Areas (SPAs) are areas outlined around groundwater abstraction points (e.g. borehole or spring) which provide drinking water. The aim of the SPAs is to protect groundwater by placing tighter controls on activities within all or part of the zone of contribution (ZOC) of the source. The Zone of Contribution (ZOC) is the land area that contributes water to the well or spring.Two Source Protection Areas (SPAs) are outlined. The Inner Protection Area (SI) aims 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) covers the rest of the zone of contribution (ZOC) to the groundwater abstraction point.Not all groundwater-fed public supply sources have SPAs outlined around them. Most studies (more than 125) have been carried out by the Geological Survey Ireland as part of County Groundwater Protection Schemes. The Environmental Protection Agency carried out more than 40 studies as part of the national groundwater monitoring network characterisation. Further studies have been carried out by consultancies for Local Authorities and Irish Water.Different methods are used to map the entire Zone of Contribution to a spring, borehole or well, resulting in different degrees of confidence associated with the boundaries of the delineated area. To be able to specify the Inner Protection Zone within the entire Zone of Contribution, knowledge or estimates of groundwater travel time within the aquifer are needed (e.g. from site-specific hydrogeological parameters or tracer tests).Source Protection Areas have been mapped by the GSI and EPA following the ‘GSI method’ (e.g., GSI/EPA/IGI Source Protection Zonation course, 2009; Kelly, 2010; DELG/EPA/GSI, 1999). These SPAs were mapped as part of County Groundwater Protection Schemes or as part of the WFD Groundwater Monitoring network characterisation. Other SPAs have been mapped by consultants for Local Authorities/Irish Water. They have not been peer-reviewed by the GSI. The Zone of Contribution and the Source Protection Area account for the ‘horizontal’ movement of groundwater. Source Protection Zones are obtained by integrating the Source Protection Areas with the groundwater vulnerability categories. The Source Protection Zone includes the complete pathway, both vertical and horizontal, for re-charge and any entrained contaminants to the abstraction point.Whereas the aim of delineating ZOCs is to define approximate areas that contribute water to an abstraction point, the aim of SPZs is to geo-scientifically characterise the pathway and receptor elements of risk to groundwater within the ZOC of a given source (Kelly, 2010). EPA prepared an advice note on “Source Protection and Catchment Management to protect Groundwater Supplies” that outlines the key measures and policies in place in Ireland (EPA, 2011).This map shows the location of SPA's which have been mapped around public supplies of groundwater in Ireland. This map is to the scale 1:20,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 200m.It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).The data is shown as polygons. Each polygon holds information on Source Protection Area such as name, code, id, data source, county, reviewed by GSI and links to online reportsGroup Water Schemes (GWSs) are community-run water supply schemes. About 70% of GWSs take their water from a privately-sourced supply. The rest take their water from an Irish Water connection (DHPLG, 2017). 81% of the privately-sourced supplies affiliated to the National Federation of Group Water Schemes (NFGWS) take groundwater from boreholes, springs and dug wells. This is around 54% by volume (NFGWS, 2018).The NFGWS is the representative for community-owned rural water services in Ireland. The NFGWS assists schemes in meeting the challenges of water quality legislation and promotes a ‘multi-barrier approach’ to source protection. The ‘multi-barrier approach’ includes delineation of the Zone of Contribution to a supply source. A Zone of Contribution (ZOC) is the land area that contributes water to a well or spring (Misstear et al., 2006). It can be considered as the ‘catchment’ to the supply source. Like surface water bodies, springs have natural catchment areas, whereas catchment areas to boreholes depend on a number of hydrogeological and meteorological factors plus the abstraction rate. A ZOC accounts for the ‘horizontal’ movement of groundwater and any entrained contamination once it has reached the water table and is moving towards the abstraction point. The aim of delineating ZOCs is to define the area that contributes water to an abstraction point. Knowledge of where the water is coming from is critical when trying to interpret water quality data at the groundwater source. The ZOC also provides an area in which to focus further investigation and is an area where protective measures can be introduced to maintain or improve the quality of groundwater.Different methods can be used to map the ZOC to a spring, borehole or dug well, resulting in different degrees of confidence associated with the boundaries of the de-lineated area. The ZOCs and accompanying reports should be considered as preliminary source protection studies. The work was undertaken by consultants under supervision and review by GSI, and represents a partnership between the GWSs, the NFGWS and GSI. The work was funded through the Rural Water Programme funding initiative of grants towards specific source protection works on GWSs (DECLG Circular L5/13 and Explanatory Memorandum).The ZOCs were delineated in the period 2011 to 2019. The maps produced are based largely on the readily available information in the area, a field walkover survey, and on mapping techniques which use inferences and judgements based on experience at other sites. As such, the maps cannot claim to be definitively accurate across the whole area covered and should not be used as the sole basis for site-specific decisions, which will usually require the collection of additional site-specific data.This map shows the location of ZOCs which have been mapped around GWS supplies of groundwater in Ireland.

A series of annual geochemical models were created by RockWare utilizing RockWorks20 which were interpolated based on the 1,4-dioxane levels that were measured during 1986 through 2023. In cases where the same intervals were samples on more than one occasion during a given year, the highest 1,4-dioxane values were used. The extent of each annual model were limited to polygons based on only the wells that were sampled during the associated year to eliminate interpolating in areas where data is not present. The annual geochemical models were then filtered based on lithology to eliminate any voxels within the areas deemed impermeable based on lithology. The models were further constrained by utilizing the maximum historical water level surface (MHWLS) grid model to further restrict the interpolation from areas lacking measured data. Finally, the voxel models were converted to annual grid models, in which the cell values are based on the highest value within the corresponding column of voxels.The 2023 plume presented here was created from the RockWorks project database files on February 27, 2024 (Gelman5_v2023.sqlite). The grid file titled 2023-01-01_to_2023-12-31.RwGrd was converted by The Mannik and Smith Group (MSG) to a raster file compatible in ArcGIS and converted to polygons of areas of concentrations between the following values: 4 ppb, 7.2 ppb, 85 ppb, 150 ppb, 280 ppb, 500 ppb, 1000 ppb, 1900 ppb, 3000 ppb, and 5000 ppb. The 7.2 ppb lines were created because it represents the current EGLE Part 201 generic residential cleanup criterion (GRCC). The 85 ppb lines were created to represent the Consent Judgement 3 (CJ3) drinking water criteria. The 280 ppb lines were created because that is the new EGLE groundwater-surface water interface (GSI) criterion, and 1900 ppb is the Vapor Intrusion criteria. EGLE is contouring the 3 ppb level as this is the trigger for response if detected in sentinel wells in the 4th Consent Judgment.This is the latest version of the Dioxane Plume data. An earlier vintage is available at: Gelman Site of 1,4-Dioxane Contamination - Dioxane Plume Map (2020 Data).This data is used in the Gelman Site of 1,4-Dioxane Contamination web map (item details).
