Aquifer test at Logan East Rural Water System. Aquifer tests were performed at the Oakland pilot site in Lower Elkhorn NRD and the Firth pilot site in Lower Platte South NRD near Hickman to assess the aquifer extent, amount of water in storage, the rate of water movement, and its potential hydraulic connection to other aquifers.

Collecting a water quality sample at Oakland Pilot Site in the Lower Elkhorn NRD. ENWRA has approximately 78 wells across the Ashland, Firth and Oakland pilot study sites that have been sampled annually, compiled in tables and graphed for water quality trends since 2007.

Test holes are drilled to obtain geoscientific data of the substrata, groundwater, and natural resources underlying Nebraska. The CSD Drilling Program drills an average of over 10,000 feet annually and has drilled nearly 6,000 test holes throughout the state since 1930. Geological material from these test holes is preserved at the University of Nebraska, School of Natural Resources, Conservation and Survey Division's Geological Sample Repository.
