Eolas Dualfhoinse Originator - Groundwater Section, Geological Survey Ireland. Most of the Source Protection Areas were delineated as part of County Groundwater Protection Schemes (DELG/EPA/GSI, 1999). GSI delineated more than 125. As part of the WFD Grounwater monitoring network characterisation, EPA delineated more than 40. The methodology used to delineate the SPAs is summarised in Kelly (2010), and GSI/EPA/IGI, 2009. It includes: liaising with the Local Authorities (LAs) to identify key sources and facilitate data collection from key staff, a desk study, a site visit to inspect the supply, the local area, interview the caretaker and collect more data. Field work included short pumping tests, drilling in the potential ZOC to determine the thickness and permeability of the overlying protective subsoils, hydrogeological data collection (e.g. groundwater levels, spring or stream flows, karst feature mapping) and collation. The data were then analysed by hydrogeologists using hydrogeological knowledge and interpretation in order to delineate the SPA. The main digital data sources, coupled with data on use and abstraction from the local authority/Irish Water, include: (1) GSI bedrock geology maps at 1:100,000; (2) GSI bedrock aquifer maps at 1:100,000; (3) GSI sand and gravel aquifer maps at 1:40,000; (4) GSI groundwater vulnerability maps at 1:40,000; (5) GSI Quaternary sediments and geomorphology maps at 1: 50,000 scale; (6) Teagasc soils maps at 1:40,000; (7) OSI High resolution digitalglobe orthophotography dataset and national digital premium basemap map service cached from 1:4,000,000 to 1:1,000 scale; (8) EPA surface water body data at 1:50,000; Hydrogeological interpretation of the data allowed delineation of the SPAs by GSI staff, consultants working on behalf of EPA, and consultants working on behalf of Local Authorities/Irish Water. The SPAs for GSI and EPA underwent a review process within the Groundwater Programme, GSI. Other SPAs may not have been peer reviewed. Many groundwater specialists have undertaken Source Protection Area delineation with GSI (since 1995) and for the EPA (since 2009). The authors of the reports are listed on the front cover of individual reports. The methodology undertaken to delineate the ZOCs includes: liaising with the GWS and NFGWS to facilitate data collection, a desk study, a site visit to inspect the supply, the local area, and to record groundwater level(s). The data were then analysed by groundwater experts using hydrogeological knowledge and interpretation in order to delineate the ZOC. The main digital data sources, coupled with data on use and abstraction from the group schemes themselves, include: (1) GSI bedrock geology maps at 1:100,000; (2) GSI bedrock aquifer maps at 1:100,000; (3) GSI sand and gravel aquifer maps at 1:40,000; (4) GSI groundwater vulnerability maps at 1:40,000; (5) GSI Quaternary sediments and geomorphology maps at 1: 50,000 scale; (6) Teagasc soils maps at 1:40,000; (7) OSI High resolution digitalglobe orthophotography dataset and national digital premium basemap map service cached from 1:4,000,000 to 1:1,000 scale; (8) EPA surface water body data at 1:50,000; Hydrogeological interpretation of the data allowed delineation of the ZOC by consultants. The ZOCs underwent a review process by Groundwater Programme, GSI, to reach a consensus on the final version of the ZOC.
