Groundwater Exploration & Protection

Ground Conductivity Surveying

Ground Conductivity Surveying

Almost 20% of Ireland’s drinking water is sourced from groundwater and springs, with a total of almost 2000 private group water schemes and small private wells across the country.

Clean water demands are increasing and Hydrogeophysics is a fast, safe and non-invasive way to investigate land for groundwater sources.

A geophysical groundwater exploration survey can locate groundwater, and also help to develop a location plan to drill your borehole without damaging or contaminating the aquifer.

The main aquifer type in Ireland is fractured or fissured bedrock. This type of aquifer can be detected by a geophysical survey through the increased conductivity or reduced resistivity of the broken rock and water mixture.


Groundwater vulnerability to contamination is linked to clay content of the soil and depth to bedrock – these factors can be mapped over large areas rapidly using electromagnetic methods.

A VLF-EM conductivity section display indicating an increased conductivity at 90m along the profile and at a depth of 50m. When this location was targeted in drilling it proved to be a high yielding water well in a generally poor bedrock aquifer.

Karst features within limestone can yield large amounts of fast-flowing ground water that can be detected using 2D-Resistivity (ERT) surveys

Groundwater Exploration & Protection

If you are looking to sink a single bore hole on your land for domestic use, or tap into a larger aquifer for agriculture use or group scheme, a survey and consultation from Minerex Geophysics will help you decide on the best course of action.

Whether you’re investigating development possibilities of a contaminated site, or you’ve discovered something mid-project that demands further inspection – we’re here to help.
