What Makes Niles's Water Unique?
Local geology and source profile
Niles, Michigan, in Berrien County — a Berrien County city adjacent to Buchanan and Edwardsburg on the St. Joseph River near the Indiana border — receives its water from the City of Niles Water Department, drawing from the St. Joseph River through the southwest Michigan distribution.
The hard 141.5 mg/L hardness and TDS of 273.7 mg/L reflect the Berrien County St. Joseph River supply's hard calcareous character — the Silurian Niagaran Carbonate and Devonian Detroit River Formation are calcareous to highly calcareous formations in the southwest Michigan-Indiana border region Michigan Basin (compare Buchanan MI: 139/269 in Berrien County comparable; Edwardsburg MI: 143/278 in Cass County comparable; Niles consistent hard from the same Berrien County St. Joseph River Silurian-Devonian calcareous supply). The St. Joseph River at Berrien County — Silurian Niagaran Carbonate (calcareous — primary hardness contributor), Devonian Detroit River Formation (highly calcareous — secondary contributor), and Quaternary glacial outwash (calcareous — TDS contributor).
At 141.5 mg/L with TDS 274, Niles' water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 8.2 ppt is elevated — a certified drinking water filter with PFAS removal is recommended — the Berrien County southwest Michigan industrial legacy contributes to Niles' elevated readings. Review the City of Niles' annual water quality report.
Geology & Source: Niles in Berrien County draws from the City of Niles Water on the St. Joseph River (Berrien County, southwest Michigan) — the St. Joseph River at Berrien County drains Silurian Niagaran Carbonate (calcareous) and Devonian Detroit River Formation (highly calcareous) — Michigan Berrien County St. Joseph River Silurian-Devonian calcareous supply produces hard water at 141.5 mg/L with TDS 273.7 mg/L.
