What Makes Webb City's Water Unique?
Local geology and source profile
Webb City, Missouri, in Jasper County — a Jasper County city adjacent to Joplin and Carterville in the Tri-State Mining District of southwest Missouri — receives its water from the City of Webb City Water Department, drawing from Shoal Creek and the Spring River watershed through the southwest Missouri distribution.
The very hard 254.5 mg/L hardness and high TDS of 636.1 mg/L reflect the Jasper County Shoal Creek supply's very hard calcareous character — the Mississippian Tri-State Formation (a highly calcareous dolomite-limestone formation known for its historic zinc-lead ore deposits) and Devonian Granby Chert are calcareous formations in the Joplin-area Ozark Plateau (compare Joplin MO: 249/622 in Jasper County comparable; Carterville MO: 258/648 in Jasper County comparable; Webb City consistent very hard from the same Jasper County Shoal Creek Mississippian calcareous supply). The Shoal Creek watershed — Mississippian Tri-State Formation (highly calcareous — primary hardness contributor), Devonian Granby Chert (calcareous — secondary contributor), and Quaternary Jasper County alluvium (calcareous — TDS contributor).
At 254.5 mg/L with TDS 636, Webb City's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 7.6 ppt warrants a certified drinking water filter. Note: Jasper County's Tri-State Mining District legacy may contribute additional trace contaminants. Review the City of Webb City's annual water quality report.
Geology & Source: Webb City in Jasper County draws from the Webb City Water on Shoal Creek watershed (Jasper County, southwest Missouri) — the Shoal Creek at Jasper County drains Mississippian Tri-State Formation (highly calcareous) and Devonian Granby Chert (calcareous) — Missouri Jasper County Shoal Creek Mississippian calcareous supply produces very hard water at 254.5 mg/L with TDS 636.1 mg/L.
