What Makes Marshall's Water Unique?
Local geology and source profile
Marshall, Missouri, in Saline County — the Saline County seat adjacent to Sedalia and Warrensburg on the Missouri River in central Missouri — receives its water from the City of Marshall Water, drawing from the Missouri River (Saline County) through the central Missouri distribution.
The hard 161 mg/L hardness and TDS of 316.3 mg/L reflect the central Missouri Saline County Missouri River supply's hard calcareous character — the Missouri River's Ozark Plateau drainage contributes significant dolomitic hardness from the Ordovician Gasconade Dolomite, mixed with Pennsylvanian calcareous input from the upland plains (compare Marshall MN: 125 mg/L on a softer Redwood River supply; Grain Valley MO: 164.5 mg/L on the Missouri River near Kansas City). The Missouri River at Saline County — Ordovician Gasconade Dolomite (dolomitic — primary hardness contributor), Pennsylvanian Cherokee Group (calcareous — secondary contributor), and Quaternary Missouri River alluvium (calcareous — TDS contributor).
At 161 mg/L with TDS 316, Marshall's water is hard. A water softener is recommended to prevent scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 5.2 ppt warrants a certified drinking water filter — the Saline County central Missouri agricultural-industrial corridor contribute to Marshall's readings.
Geology & Source: Marshall in Saline County draws from the City of Marshall Water on the Missouri River (Saline County, central Missouri) — the Missouri River at Saline County drains the Ozark Plateau (Ordovician Gasconade Dolomite — dolomitic) and Pennsylvanian Cherokee Group (calcareous) — Missouri Saline County Missouri River Ordovician-Pennsylvanian calcareous supply produces hard water at 161 mg/L with TDS 316.3 mg/L.
