What Makes Hutchinson's Water Unique?
Local geology and source profile
Hutchinson, Kansas, the Reno County seat — the 'Salt City' (Hutchinson sits atop one of the world's largest underground salt mines — the Hutchinson Salt Company, now part of Compass Minerals, mining Permian halite from the Wellington Formation), home of the Kansas State Fair (the largest annual event in Kansas), the Cosmosphere (one of the world's largest air and space museums, housing the largest collection of Russian space artifacts outside Russia), and a major south-central Kansas agricultural and industrial community — draws its municipal water supply from the Equus Beds Aquifer via the City of Hutchinson Water Division. Water hardness in Hutchinson measures 243.5 mg/L — classified as very hard.
Hutchinson's very hard supply reflects the Reno County Permian evaporite geology — the same geology that produced the famous Hutchinson salt mines. The Equus Beds Aquifer and Arkansas River alluvial aquifer at Hutchinson overlie and are influenced by: the Permian Wellington Formation (highly calcareous evaporite — rock salt, gypsum, and anhydrite — the formation that produced the Hutchinson salt domes and salt mines); the Permian calcareous Sumner Group (calcareous and evaporite Permian sequence); and Quaternary calcareous loess and Arkansas River alluvium (calcareous windblown and alluvial deposits). The Permian evaporite dissolution produces the very hard 243.5 mg/L.
At 243.5 mg/L, Hutchinson residents face severe hard water challenges. Weekly descaling and appliance protection measures are strongly recommended. City of Hutchinson Water Division consistently delivers water meeting all Kansas KDHE and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Equus Beds Aquifer (Arkansas River alluvial and dune sand aquifer) via the City of Hutchinson Water Division — the Reno County south-central Kansas Arkansas River Valley (Permian calcareous Wellington Formation evaporite and Quaternary calcareous loess and Arkansas River alluvium); very hard supply at 243.5 mg/L — reflecting the Permian evaporite dissolution in the Hutchinson zone.
