Groundwater Investigation Using Very Low Freguency …
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.
