VLF surveys are conducted to locate fractures that can be exploited for groundwater production. Several surveys were performed using the ABEM Wadi and a 23.9-kHz signal from the transmitter located in Cutler, Maine. A sub-meter-accurate Global Positioning System (GPS) was used for exact spatial positioning of collected data.

The EM16 VLF Receiver is the most widely used electromagnetic geophysical instrument of all time. Local tilt and ellipticity of VLF broadcasts are measured and resolved into inphase and quadrature components of VLF response. The EM16 has discovered several base and precious-metal ore bodies and many water-bearing fractures and faults.
