What Makes Great Bend's Water Unique?
Local geology and source profile
Great Bend, Kansas, in Barton County — the Barton County seat adjacent to Ellinwood and Stafford on the Arkansas River in central Kansas — receives its municipal water from the Great Bend Water Division, drawing from Rattlesnake Creek (a tributary of the Arkansas River, Barton County) and the High Plains (Ogallala) Aquifer through the central Kansas water treatment system.
The extremely hard 457.5 mg/L hardness and extremely high TDS of 1551.9 mg/L are the highest in this dataset — the central Kansas High Plains Aquifer and Rattlesnake Creek are among the most mineralized water sources in the USA, driven by the dissolution of the underlying Permian evaporites. The High Plains Aquifer at Barton County is underlain by Permian Nippewalla Group (red beds with halite and gypsum — dominant TDS contributor), Permian Blaine Formation (pure gypsum — the primary hardness and sulfate contributor), and Permian Flowerpot Formation (gypsum and anhydrite). The concentrated gypsum dissolution drives hardness to near-brine levels.
At 457.5 mg/L with TDS 1552, Great Bend's water is extremely hard. A water softener and reverse osmosis system are essential. Scale forms almost immediately on all surfaces, appliances fail within months without treatment, and drinking water is strongly recommended to be filtered. The PFAS level of 6.1 ppt warrants a certified reverse osmosis drinking water filter — the Barton County central Kansas agricultural chemical corridor and the Arkansas River PFAS background contribute to Great Bend's readings.
Geology & Source: Great Bend in Barton County draws from the Great Bend Water Division on the Rattlesnake Creek and High Plains Aquifer (Barton County, central Kansas) — the Rattlesnake Creek-High Plains watershed drains the Permian Nippewalla Group evaporite and Permian Blaine Formation (gypsum — intensely evaporitic) — Kansas Barton County High Plains Permian evaporitic aquifer produces extremely hard water at 457.5 mg/L with TDS 1551.9 mg/L in this Barton County Kansas city.
