What Makes Neosho's Water Unique?
Local geology and source profile
Neosho, Missouri, in Newton County — a Newton County city adjacent to Joplin on the Neosho River in southwest Missouri — receives its water from the City of Neosho Water, drawing from the Neosho River (Newton County) through the southwest Missouri distribution.
The hard 193 mg/L hardness and TDS of 414.4 mg/L reflect the southwest Missouri Newton County Ozark Plateau supply's hard calcareous character — the Mississippian Burlington Limestone calcareous and Pennsylvanian Krebs Group slightly calcareous produce hard water throughout the Ozark-Ouachita transition communities in southwest Missouri (compare Joplin MO: 198/431 in Jasper County comparable; Neosho essentially the same Ozark plateau calcareous supply). The Neosho River at Newton County — Mississippian Burlington Limestone (calcareous — primary hardness contributor), Pennsylvanian Krebs Group (slightly calcareous — secondary contributor), and Quaternary Neosho alluvium (calcareous — TDS contributor).
At 193 mg/L with TDS 414, Neosho'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 6.1 ppt warrants a certified drinking water filter — the Newton County southwest Missouri industrial and military (Neosho Arsenal history) corridor contribute to Neosho's elevated readings.
Geology & Source: Neosho in Newton County is served by City of Neosho Water drawing from the Neosho River — the Neosho River watershed drains the Ozark Plateau (Mississippian Burlington Limestone — calcareous) and Pennsylvanian Krebs Group (slightly calcareous) — MO Newton County Neosho River Mississippian-Ozark calcareous supply produces hard water at 193 mg/L with TDS 414.4 mg/L.
