Why is the Dakota formation not widely used in central and western Nebraska?

The Dakota formation is not widely used in central and western Nebraska primarily because it tends to be too salty and is often found at significant depths. This salinity makes the water quality unsuitable for most applications, including agricultural and municipal use, as high salt content can harm crops and corrode plumbing systems. Additionally, the deep burial of the Dakota formation means extracting resources from it can be cost-prohibitive and technically challenging, further limiting its usability. Therefore, the combination of salinity and depth plays a crucial role in why it is not a preferred source in the region.
