Locating Faults in Fractured Aquifers
Groundwater extraction in regions with weathered crystalline rocks can be challenging due to low permeability resulting from high clay content. A common solution involves locating deeper, unweathered fault zones with higher permeability.
Our Solution:
We use geophysical techniques like electrical resistivity profiling to identify these fault zones. By adjusting electrode spacing based on depth, we can pinpoint areas ideal for water extraction, ensuring accurate and efficient exploration.
Understanding Water Table Dynamics
In sedimentary basin, groundwater is stored within the pore spaces of rock layers. However, factors like porosity, permeability, fractures, and karst networks can cause significant variations in water table thickness and distribution.
Our Solution:
-
• Electrical Sounding
This straightforward method uses a four-electrode system to gather resistivity data at increasing depths. It provides a clear resistivity log, which is perfect for determining groundwater characteristics.
-
• Electrical Resistivity Tomography (ERT)
For more complex geological conditions, we use ERT to create detailed 2D images of groundwater variations, helping you choose the best drilling sites.
Managing Saltwater Intrusion
In coastal areas, over-pumping groundwater can cause saltwater to seep into freshwater aquifers, endangering water supplies, agriculture, and industries.
Our Solution:
Using resistivity soundings and tomography, we map the extent of saltwater intrusion and help manage risks to preserve freshwater resources.
