Reno County, Kansas: drinking water report. Reno County in south-central Kansas has about 63,000 residents, with Hutchinson as the county seat.
Reno County in south-central Kansas has about 63,000 residents, with Hutchinson as the county seat. The Equus Beds Aquifer – a critical groundwater source for the Wichita metro area – underlies the county. Hutchinson draws from both the aquifer and the Arkansas River. The county sits atop one of the world's largest underground salt deposits, and the mining of that salt for over a century has created unique water quality challenges.
Salt contamination from brine disposal and mining operations has affected the Equus Beds Aquifer in Reno County. According to the Kansas Geological Survey's 2024 aquifer report, chloride concentrations in the aquifer have been increasing in the central part of the county, with some monitoring wells exceeding 250 mg/L – the secondary drinking water standard. The Carey Salt and Hutchinson Salt companies operated dissolution mining that left subsurface voids and contaminated groundwater.
The former Hutchinson Naval Air Station used AFFF during WWII-era flight training. KDHE's 2024 PFAS investigation detected PFOS at 11 ppt in monitoring wells near the former facility. Agricultural nitrate from the surrounding wheat and sorghum farmland adds to the aquifer contamination picture.
Reno County's salt geology creates a unique baseline of elevated minerals that is distinct from agricultural or industrial contamination. If your water tastes salty or leaves white residue, the source may be geological rather than man-made – but the health implications of elevated sodium and chloride are the same.
Check your water for current data. For salt contamination and PFAS, reverse osmosis is the only household technology that removes dissolved salts effectively.
