Nitrate Concentration

In the late 1970’s to the early 1990’s, with coordination with KGS staff, the District initiated a study of the water quality in the eastern half of the District. Specifically, this study identified the intrusion of saltwater (from the dissolution of salt) in the Permian bedrock into the overlying Great Bend Prairie aquifer. This area became known as the mineral intrusion area and in 2003, the District established rules to regulate water quality sampling within this region.
