Finding groundwater could be easy.

Finding enough is harder.

Geophysical methods open a unique window into the depths of the Earth and offer diverse sophisticated tools utilized for imaging the subsurface (and other surfaces) by mapping physical properties. The relevancy of geophysics to engineering and to the environment is evidenced in the valuable information it provides and in economic benefits for the client.

The goal of geophysical surveys for groundwater exploration is not just to find water, but to identify drilling locations with the most potential for optimal production rates.

Once the depth to water table is known, drilling to that depth from almost any location in the target area will encounter some amount of water. The significant challenge is finding the quality and quantity necessary for development while making the best use of investment and drilling dollars.

Housing and economic development is constrained by available water in many locations worldwide. Water wells are increasingly deeper, making drilling an expensive endeavour and foolhardy without adequate geophysical data.

Advantages of Geophysical Methods:

  • Quick spatial scanning: geophysical methods enable the coverage of a large area relatively quickly, as compared with intrusive methods, such as observation drilling. Furthermore, the implementation of geophysical methods allows reducing the number of required observation boreholes and also supplies data about the areas located between them.
  • Non-intrusive methods: geophysical methods do not involve destruction and excavation. Most of the methods are silent and environmentally friendly, and can therefore be implemented at all hours of the day, including in densely populated areas.
  • Comprehensive, detailed survey: geophysical methods meet needs that intrusive methods are incapable of answering, or that are too expensive, such as providing continuous data regarding the level of groundwater, or the volume of voids in the soil / in concrete. Different geophysical methods may be integrated in order to provide a comprehensive, yet focused response to each client's particular needs.
  • Economic considerations: geophysical methods that are implemented at ground surface do not require digging or excavations, and therefore enable the scanning of a greater volume of the subsurface at reduced costs, even in comparison with a drilling matrix.
  • Proven effectiveness: geophysical methods have been widely used throughout the world for over 50 years.
