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 They have not been peer-reviewed by the GSI.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.

Abstract: This data shows the watercourses forming part of Drainage Districts. Drainage Districts were carried out by the Commissioners of Public Works under a number of drainage and navigation acts from 1842 to the 1930s to improve land for agriculture and to mitigate flooding. Channels and lakes were deepened and widened, weirs removed, embankments constructed, bridges replaced or modified and various other work was carried out. The purpose of the schemes was to improve land for agriculture, by lowering water levels during the growing season to reduce waterlogging on the land beside watercourses known as callows. Local authorities are charged with responsibility to maintain Drainage Districts. The Arterial Drainage Act, 1945 contains a number of provisions for the management of Drainage Districts in Part III and Part VIII of the act. The Act was amended on a number of occasions, e.g. to transpose EU Regulations and Directives such as the EIA, SEA, and Habitats Directives and the Aarhus Convention. Lineage: The original sources for the information displayed in this dataset were the maps and descriptive documents, known as the Award, which were created when these schemes were completed to describe the work carried out. These maps were digitised between 2001-2004 from Ordnance Survey of Ireland 1:10,560 six-inch raster data in Irish Grid. Distortion arises from the historic Cassini map projection used in the original maps. Scale along the central meridian and at right angles to it is accurate, but everywhere else, scale, and therefore mapped objects, are distorted in a north-to-south direction. The amount of distortion on the map increases with distance from the central meridian. In Ireland, the Cassini projection was applied on a county-by-county basis for six-inch mapping, with the central meridian passing through a point near the centre of the county. Therefore, distortion is most evident near county borders, and also in rivers, lakes and streams. Distortion and error inherent in the dataset are amplified during translation and re-projection using Irish Grid and Irish Transverse Mercator. Purpose: This data has been developed to support the maintenance of Drainage Districts carried out under a number of drainage and navigation acts from 1842 to the 1930s. This work was initially carried out by the Commissioners of Public Works to improve land for agricultural purposes. Local authorities are now charged with the responsibility to maintain the Drainage Districts. Maps and descriptive documents, known as the Award, were created when these schemes were completed to describe the work carried out.

This map shows drainage classes of soils across Ireland based on examination of the soil profile. Organic soils, comprising either peat or alluvium, are separated out from four drainage classes across mineral soils; well drained, imperfectly drained, poorly drained or very poorly drained. Made ground in urban areas is also illustrated.

The Irish Soil Information System adopted a unique methodology combining digital soil mapping techniques with traditional soil survey application. Developing earlier work conducted by An Foras Talúntais, the project generated soil-landscape models for previously surveyed counties. These soil-landscape (‘soilscape’) models formed the basis for training statistical ‘inference engines’ for predicting soil mapping units, checked during field survey. 213 soil series are identified, each with differing characteristics, having contrasting environmental and agronomic responses. Properties were recorded in a database able to satisfy national and EU policy requirements. The Irish soil map and related soil property data will also serve public interest, providing the means to learn online about Irish soil resources. Use the Symbology layer file 'SOIL_SISNationalSoil.lyr' based on Value Field 'Association_Unit'. SIS SOIL DRAINAGE:In Ireland, soil drainage category is considered to have a predominant influence on soil processes (Schulte et al., 2012). The maritime climate of Ireland drives wet soil conditions, such that excess soil moisture in combination with heavy textured soils is considered a key constraint in relation to achieving productivity and environmental targets. Both soil moisture content and the rate at which water drains from the soil are critical indicators of soil physical quality and the overall functional capacity of soil. Therefore, a natural extension to the Irish Soil Information System included the development of an indicative soil drainage map for Ireland. The soil subgroup map was used to develop the indicative drainage map, based on diagnostic criteria relating to the subgroup categorization. Use the Symbology layer file 'SOIL_SISSoilDrainage.lyr' based on Value Field 'Drainage'. SIS SOIL DEPTH: Soil depth is a measure of the thickness of the soil cover and reflects the relationship between parent material and length of soil forming processes. Soil depth determines the potential rooting depth of plants and any restrictions within the soil that may hinder rooting depth. Plants derive nearly 80 per cent of their water needs from the upper part of the soil solum, i.e. where the root system is denser. The rooting depths depend on plant physiology, type of soil and water availability. Generally, vegetables (beans, tomatoes, potatoes, parsnip, carrots, leek, broccoli, etc.) are shallow rooted, about 50–60 cm; fruit trees and some other plants have medium rooting depths, 70–120 cm and other crops such as barley, wheat, oats, and maize may have deeper roots. Furthermore, rooting depths vary according to the age of the plants. The exact soil depth is difficult to define accurately due to its high variability across the landscape. The effective soil depth can be reduced by the presence of bedrock or impermeable layers. Use the Symbology layer file 'SOIL_SISSoilDepth.lyr' based on Valued Field 'Depth'. SIS SOIL TEXTURE:Soil texture is an important soil characteristic that influences processes such as water infiltration rates, rootability, gas exchanges, leaching, chemical activity, susceptibility to erosion and water holding capacity. The soil textural class is determined by the percentage of sand, silt, and clay. Soil texture also influences how much water is available to the plant; clay soils have a greater water holding capacity than sandy soils. Use the Symbology layer file 'SOIL_SISSoilTexture.lyr' based on Value Field 'Texture'. SIS SOIL SOC:In the previous national soil survey conducted by An Foras Taluntais, 14 counties were described in detail with soil profile descriptions provided for the representative soil series found within a county. Soil samples were taken at each soil horizon to a depth of 1 meter and analyses performed for a range of measurements, including soil organic carbon, texture, cation exchange capacity, pH; however in most cases no bulk density measurements were taken. This meant that while soil organic carbon concentrations were available this could not be related to a stock for a given soil series. In 2012/2013, 246 profile pits were sampled and analysed as part of the Irish Soil Information System project to fill in gaps in the description of representative profile data for Ireland. Use the Symbology layer file 'SOIL_SISSoilSOC.lyr' based on Value Field 'SOC'.

Groundwater Protection Scheme Reports 50k Ireland (ROI) ITM. Published by Geological Survey Ireland. Available under the license Creative Commons Attribution 4.0 (CC-BY-4.0).The Scheme Reports Groundwater Protection map provides links to county based reports.

A groundwater protection scheme has land surface zone map(s) and groundwater protection responses for potentially polluting activities e.g., landfill, land spreading and septic tanks.

The role of the GSI is to create the land surface zoning map, whereas decisions on groundwater protection responses are the responsibility of the statutory authorities.

The GSI use groundwater vulnerability, aquifer and source protection areas maps to produce Groundwater Protection Zones.

Each zone is classified with a code (e.g., Rf/H), which allows the risk to groundwater to be assessed, independent of any hazard or contaminant type. It is a guide to assess how suitable an area is for an activity e.g., landfill. A site investigation should then be carried out.

Once the groundwater protection zone is classified for an area, the hazards posed by human activities can be evaluated to assess the appropriate risk management measures, or Groundwater Protection Responses, for these activities. The Groundwater Protection Responses, which are shown by a code (e.g., R2¹), outline how likely the activity will be accepted in that area. Full details are available which describe all necessary actions which need to be taken. Responses are available for landfills, landspreading of organic wastes, on-site wastewater treatment systems (e.g., septic tanks), out wintering pads and earth-lined slurry stores.

The Groundwater Recharge map shows where different amounts of rainfall reach the stores of groundwater (the ‘aquifers’) across Ireland. The estimated average annual recharge amount is shown in units of millimetres per year (mm/yr). The amount of recharge was calculated over the period 1981-2010 and then averaged to give a yearly amount. The groundwater recharge map shows estimated average annual recharge to the deep groundwater system. The ‘deep groundwater’ can be tapped steadily year-round and yields aren’t significantly influenced by seasonal changes. The main geological controls on groundwater recharge include soil drainage, subsoil type, subsoil permeability, subsoil thickness, and the ability of the underlying aquifer to accept percolating waters. This map is best displayed to the scale 1:40,000 (1cm on the map relates to a distance of 400m). Users of the map should be aware that for each hydrogeological scenario, the map uses the typical recharge coefficient from an available range. It also uses the 30 year average effective rainfall. This means that groundwater recharge may be over- or under-estimated, depending on local conditions. Users should also be aware that the recharge cap applied to poorly productive aquifers may need further examination for particular studies

The Scheme Reports Groundwater Protection map provides links to county based reports.A groundwater protection scheme has land surface zone map(s) and groundwater protection responses for potentially polluting activities e.g., landfill, land spreading and septic tanks.The role of the GSI is to create the land surface zoning map, whereas decisions on groundwater protection responses are the responsibility of the statutory authorities. The GSI use groundwater vulnerability, aquifer and source protection areas maps to produce Groundwater Protection Zones.Each zone is classified with a code (e.g., Rf/H), which allows the risk to groundwater to be assessed, independent of any hazard or contaminant type. It is a guide to assess how suitable an area is for an activity e.g., landfill. A site investigation should then be carried out.Once the groundwater protection zone is classified for an area, the hazards posed by human activities can be evaluated to assess the appropriate risk management measures, or Groundwater Protection Responses, for these activities. The Groundwater Protection Responses, which are shown by a code (e.g., R2¹), outline how likely the activity will be accepted in that area. Full details are available which describe all necessary actions which need to be taken. Responses are available for landfills, landspreading of organic wastes, on-site wastewater treatment systems (e.g., septic tanks), out wintering pads and earth-lined slurry stores.This map is to the scale 1:50,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 500m.It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas). The county data are shown as polygons. Each polygon holds information on the province, county , a link to a report page on our website and a field showing if a Groundwater Protection Scheme Report has been published, or any other report such as a water quality or source protection report. The map displays counties areas in green if a Groundwater Protection Scheme Report has been published, counties in orange if any other report has been published for that area (water quality, source protection) and red if no reports have been published.

Groundwater is the water that soaks into the ground from rain and is stored beneath the ground. An aquifer is a body of rock and/or sediment that holds groundwater. The process of rain filling up an aquifer is called ‘recharge’. The Groundwater Recharge map shows the amount of rainfall which reaches the stores of groundwater (the ‘aquifers’) across Ireland. The amount of recharge was calculated over the period 1981-2010 and then averaged to give a yearly amount.Geological information is interpreted by hydrogeologists to create the map includes soil drainage, subsoil type, subsoil permeability, subsoil thickness, groundwater vulnerability and aquifers. The amount of rain falling on the land minus how much of that rain is taken up by plants is also a factor that determines how much groundwater recharge there is at a particular location. This is known as the ‘effective rainfall’.Different combinations of the geological factors give 24 hydrogeological scenarios. There is a ‘recharge coefficient’ for each scenario, which is the percentage of the ‘effective rainfall’ that may become groundwater recharge. Using ArcGIS software, the data are merged to create areas on a map to show the recharge. Please read the lineage for more detail.This 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 recharge data is shown as polygons. Each polygon holds information on:Average Recharge (mm/yr) - average annual recharge to the groundwater aquifer across that polygonRecharge Coefficient (%) – the proportion of effective rainfall that becomes groundwaterEffective Rainfall (mm/yr) – the rainwater remaining after plants have taken up some of the rainfallRecharge Pre Cap (mm/yr) - effective rainfall x recharge coefficient, not limited by maximum recharge capacitiesRecharge Cap Apply – is there a maximum amount of recharge that the aquifer can accept? (Yes/ No)Recharge Maximum Capacity (mm/yr) – the maximum amount of recharge the aquifer can accept. Only applies to bedrock aquifers of category Ll, Pl, or Pu.Average Recharge Range (mm/yr) - Annual Recharge (mm) categorised into a range of values used to style the map.

Introduction

The Historical Flood Events map service is a multi layered dataset which shows known areas that have been inundated by flood water in the past. These flooded area outlines have been generated from archived field data and aerial photographs that were collected by Rivers Agency at the time of the actual flood events. In all, over 60 separate events are recorded going back to 1971. The following layers are included: • Historical Flood Outlines • Locations of Aerial Photographs indicating flooding

Purpose of the data

The data is used to understand where flooding has occurred in the past and to provide records of the details. Absence of an historic flood event outline for an area does not mean that the area has never flooded, only that the Rivers Agency does not currently have records of flooding in this area. Similarly, the inclusion of a record of a flood event outline does not necessarily mean that the area will flood again. Flood alleviation schemes will have been undertaken at some of the flood prone locations and this work will have significantly reduced the likelihood of future flooding at these areas

Data Coverage

All of Northern Ireland, and some limited coverage in Republic of Ireland in border areas. Data Format OGC (Open Geospatial Consortium) compliant Web Mapping Service in WGS 1984 projection, accessible via secure website (requires authentication by user specific username and password)..
