Mapping Groundwater

Applying geoscanners for mapping groundwater

Locate suitable groundwater aquifers

In areas with limited access to surface water, or where surface water is seasonal and/or contaminated, a groundwater solution could be an option.  

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.  

To improve the likelihood of drilling water producing boreholes or wells, it is highly recommended to use geophysical methods like geoscanner (tTEM or sTEM) for mapping the location of aquifers before any investigations for drilling are made.  

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 is from groundwater. Mapping the distribution and extent of groundwater resources is crucial for effective water resource management. The geoscanner played a key role in this application by measuring 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 and deliver high-resolution maps in many countries.
