Integrated Geophysical Survey as Applied to Groundwater exploration

The town of Mamre is completely dependant on groundwater for water supply. The potable<br>water supplied by the Atlantis wellfield is an expensive water source to use for irrigation.<br>This instigated a geophysical investigation into locally occurring groundwater for irrigation.<br>The shallow seismic reflection, electromagnetic and resistivity methods were successfully<br>used to delineate areas for groundwater development. The seismic data were used to<br>quantitatively determine depth to bedrock, whereas the electromagnetic and resistivity data<br>were used to give a qualitative estimation of zones of deeper weathering.
