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.

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. Karst features within limestone can yield large amounts of fast-flowing ground water, which we can be detect using 2D-Resistivity (ERT) surveys

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, and displayed using the VLF-EM image below.

 This VLF-EM conductivity section display indicates 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.

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.

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.
