Locate suitable groundwater aquifers.
A groundwater solution could be an option in areas with limited access to surface water or where surface water is seasonal and/or contaminated.
The challenge with groundwater aquifers is that it’s often difficult to locate suitable aquifers, especially in regions with little to no available information about local hydrological systems, where drilling dry wells can be a significant risk.
Geophysical methods like geoscanners (tTEM or sTEM) are highly recommended for mapping the location of aquifers before any drilling investigations are made to improve the likelihood of drilling water-producing boreholes or wells.
In some areas, the success rate of boreholes may be as low as 1:10 (10%), but by using a geoscanner, the success rate will increase up to 1:2 (50%), thereby minimizing the cost.
In Denmark, nearly 100 % of all drinking water comes from groundwater. Mapping the distribution and extent of groundwater resources is crucial for effective water resource management. The geoscanner played a vital role in this application by measuring the size of the subsurface aquifers and the protective clay layers.
Our geoscanners offer a wealth of applications in searching for groundwater, from placing well locations to imaging subsurface flow paths. They also deliver high-resolution maps in many countries.
