Groundwater Enquiries
In 1999 GSI's Groundwater Programme answered almost 1,000 enquiries from hydrogeologists, engineers and the general public. By 2006 this number had reached more than 1,650.

The types of enquiry vary greatly across Groundwater's various activity areas.  These include: 
  • Karst Potential: We maintain a database of karst features, showing the location and relevant characteristics of individual karst features across Ireland. This database is updated when new information is submitted.
  • Borehole Records: Drillers' and consultants' logs are available for some wells in each county. At best, these logs can give information on the depth to bedrock, subsoil type, bedrock type, groundwater strikes, and groundwater rest levels. Unfortunately, many of the logs are not very comprehensive and often do not contain accurate location information.
  • Well Hydrographs: Long-term groundwater level data are available for wells in several aquifers types in Counties Cork, Kerry, Kildare, Laois, Louth, Roscommon, and Tipperary.
  • Aquifer Classification: If an area is not yet covered by a Groundwater Protection Scheme, we can provide a provisional aquifer classification for the area in question.
