What Makes Grandville's Water Unique?
Local geology and source profile
Grandville, Michigan, in Kent County — a Kent County city adjacent to Wyoming and Grand Rapids on the Grand River in west Michigan — receives its municipal water from the Grandville Water Division or Grand Rapids DPW, drawing from the Grand River (Kent County) through the Grand Rapids water treatment system.
The very hard 220 mg/L hardness and elevated TDS of 548.1 mg/L reflect the west Michigan Grand River supply's intense Silurian-Devonian carbonate character — consistent with other Grand River watershed communities. The Grand River at Kent County drains the Michigan Till Plain — Silurian Niagara Dolomite (very high purity dolomite bedrock — the dominant west Michigan carbonate platform), Devonian Traverse Group limestone (calcareous — very hard), and calcareous Pleistocene Lake Michigan Lobe till (glacially ground dolomite and limestone). The near-pure Niagara Dolomite and Devonian Traverse limestone produces the very hard west Michigan Grand River supply.
At 220 mg/L with TDS 548, Grandville's water is very hard — scale builds steadily in all applications, dishwashers need rinse aid, and water heaters should be descaled annually. Monthly descaling is recommended. The PFAS level of 12.2 ppt is among the highest in this dataset — Wolverine World Wide (Kent County — Scotchgard PFAS from shoe tanning, contaminating the Rogue River-Grand River watershed — one of the most significant industrial PFAS contamination sites in Michigan), Camp Grayling (Crawford County — AFFF migrating southward), and the west Michigan industrial PFAS complex contribute to Grandville's very elevated readings.
Geology & Source: Grandville in Kent County draws from the Grandville Water Division on the Grand River (Kent County, west Michigan) — the Grand River drains the Michigan Till Plain (Silurian Niagara Dolomite, Devonian Traverse Group limestone — highly calcareous) — Michigan Kent County Grand River Silurian-Devonian carbonate watershed produces very hard water at 220 mg/L with TDS 548.1 mg/L in this Kent County Michigan city.
