What Makes Bellefontaine Neighbors's Water Unique?
Local geology and source profile
Bellefontaine Neighbors, Missouri, in Saint Louis County — a Saint Louis County city adjacent to Ferguson and Berkeley in the north St. Louis suburbs — receives its water from Missouri American Water, drawing from the Missouri River through the east-central Missouri distribution.
The hard 151 mg/L hardness and TDS of 287.9 mg/L reflect the Saint Louis County Missouri River supply's hard calcareous character — the Pennsylvanian Kansas City Limestone and Ordovician Gasconade Dolomite are calcareous formations in the Missouri Ozark Plateau, and the Missouri River acquires dissolved mineral content from its extensive limestone-dolomite drainage (compare Ferguson MO: 148/280 in Saint Louis County comparable; Berkeley MO: 153/295 in Saint Louis County comparable; Bellefontaine Neighbors consistent hard from the same Saint Louis County Missouri River Ordovician calcareous supply). The Missouri River watershed — Pennsylvanian Kansas City Limestone (calcareous — primary hardness contributor), Ordovician Gasconade Dolomite (calcareous — secondary contributor), and Quaternary Missouri River alluvium (calcareous — TDS contributor).
At 151 mg/L with TDS 288, Bellefontaine Neighbors' water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 5.0 ppt is moderate — a certified drinking water filter provides added protection. Review Missouri American Water's annual water quality report.
