The state of South Dakota in US plans to tap into the water resource not above the ground but below it. Mark Cotter, Director of Public Works in Sioux Falls, addressed the big plan for mapping the underground water source. The instrument is called the “Bird” by many, “RESOLVE” by others, and it will be hovering just about 100-feet above the ground; collecting data right below the Earth’s surface. The tool will be flown via helicopter sending low-frequency pulses into the Earth’s surface mapping a three-dimensional view of the Big Sioux Aquifer – which is much more efficient and cost effective than what was done in the past.
