What Makes Council Bluffs's Water Unique?
Local geology and source profile
Council Bluffs, Iowa, the Pottawattamie County seat on the Missouri River opposite Omaha, Nebraska — a historic transcontinental railroad hub (eastern terminus of the Union Pacific) and Lewis and Clark campsite — draws its municipal water supply from the Missouri River via the Iowa American Water Council Bluffs Water Division, treating Missouri River water for Council Bluffs. The Missouri River at Council Bluffs has drained the entire upper Great Plains basin from the Montana Rockies. Water hardness in Council Bluffs reaches an extraordinary 361 mg/L — classified as extremely hard, one of the highest municipal water hardness levels in the United States.
Council Bluffs's extreme hardness reflects the Missouri River's massive calcareous mineral accumulation from the Great Plains. At the Council Bluffs gauge, the Missouri River carries the accumulated dissolved calcium from: the Permian evaporite belt of Kansas, Nebraska, and the Dakotas (Permian Niobrara and Greenhorn Formations — calcareous chalk and marl; Permian Blaine Formation gypsum and anhydrite); the Cretaceous Pierre Shale (highly calcareous marine shale of the Western Interior Seaway — extensively exposed throughout the Missouri River drainage basin in the Dakotas and Montana); the Montana and Wyoming carbonate formations (Jurassic Morrison, Triassic Chugwater, and Permian Phosphoria — calcareous); and the concentrated glacial calcareous till drainage of the upper Missouri plains. The Missouri River at Council Bluffs is among the hardest major river supplies in North America.
At 361 mg/L, Council Bluffs residents face some of the most severe hard water challenges in the US. Scale forms within 24–48 hours on all surfaces. Daily descaling may be necessary. Iowa American Water consistently delivers water meeting all Iowa DNR and EPA Safe Drinking Water Act requirements, but home water softeners are strongly advisable.
Geology & Source: River supply from the Missouri River via the Iowa American Water Council Bluffs Water Division — the Missouri River basin (Precambrian Rocky Mountain, Permian Great Plains evaporite, and the Cretaceous Pierre Shale drainage) at the western Iowa Missouri River bluffs; extremely hard supply at 361 mg/L — one of the hardest public water supplies in the United States.
