ENWRA continues to employ SkyTEM method to map aquifers

SkyTEM is happy to announce that we are again working with Eastern Nebraska Water Resources Assessment (ENWRA) in their multi-year programme to map groundwater resources in the State.  Several Natural Resource Districts (NRDs) have joined together to take advantage of the SkyTEM system and each has planned a mix of survey goals. SkyTEM is a helicopter-borne geophysical system capable of mapping subtle changes in geology from the very near surface to depths over 500 m.

In 2006 the NRDs determined that careful management of all aquifers, even those not directly connected to surface water, are important because the localized and hydrogeologically-complex nature of many aquifers in eastern Nebraska makes them susceptible to overdevelopment and depletion. The ultimate goal of ENWRA is to develop a three-dimensional geologic framework for all of eastern that can be used to determine location, depth to and volume of aquifers. ENWRA worked with the U.S. Geological Survey to assess geophysical tools for their applicability in mapping buried aquifers under deep layers of glacial till as found in parts of Nebraska. SkyTEM is pleased to have been selected for this year’s projects, and for all the previous years ENWRA has employed our unique technology.

The SkyTEM method, specifically developed to map buried aquifers, is widely accepted globally as the principal technique for mapping water resources. SkyTEM is an innovative and technologically advanced airborne geophysical system capable of mapping the top 500 metres of the Earth in fine detail and in 3 dimensions. It was conceived and engineered in Denmark, a country with a reputation for environmental care and R&D. SkyTEM has helped geological organizations and government water agencies on seven continents unearth a wealth of information about their aquifers and aided in their understanding of how geology and mankind can affect, and be affected by, groundwater resources. The SkyTEM method has mapped water resources on a Galapagos Island, important agricultural areas in the USA, Australia, Africa and India, islands in the Caribbean and Indian Ocean and even Antarctica. Recognized for its ability to quickly and accurately map geology in fine detail, the SkyTEM method is also employed globally for mineral and oil & gas exploration as well as environmental and engineering investigations.
