Wells & Springs (Ireland)
What this layer shows
GSI's national register of water wells, boreholes and springs: depth, depth to bedrock, yield class and reported abstraction, where GSI holds a record. 36,273 sources, drawn as ACCURACY CIRCLES from 5 m to 2.5 km wide rather than exact positions. It is a record of what has been reported to GSI, not a complete register of every well in the country.
Where the data comes from

Merestone asks this service live for the area on screen. Nothing is copied or stored beyond a short cache.
Facts shown for each feature
Depth of hole (m) · Depth to bedrock (m) · Yield class

Groundwater & geology
Aquifers, vulnerability, subsoils, bedrock and radon.
Farming
Nutrient planning for Irish farms: where nitrate and phosphorus are most likely to reach water (the EPA's high-rank critical source areas), which agricultural pressure each sub-basin needs work on, groundwater vulnerability, soils, wells and septic-tank risk. Ireland runs a whole-territory Nitrates Action Programme, so risk grades come from these layers rather than from NVZ boundaries.
