What Makes Grand Haven's Water Unique?
Local geology and source profile
Grand Haven, Michigan, in Ottawa County — an Ottawa County city adjacent to Spring Lake and Ferrysburg at the mouth of the Grand River on Lake Michigan — receives its water from the City of Grand Haven Water Department, drawing from the Grand River through the west-central Michigan distribution.
The very hard 216 mg/L hardness and TDS of 531.5 mg/L reflect the Ottawa County Grand River supply's very hard dolomitic character — the Silurian Niagaran Dolomite and Ordovician Trenton Limestone are highly calcareous formations in the Michigan Basin, and the Grand River acquires substantial dissolved mineral content from its extensive limestone and dolomite drainage across the west Michigan Lake Plain (compare Spring Lake MI: 212/522 in Ottawa County comparable; Ferrysburg MI: 219/540 in Ottawa County comparable; Grand Haven consistent very hard from the same Ottawa County Grand River Silurian dolomitic supply). The Grand River at Ottawa County — Silurian Niagaran Dolomite (highly dolomitic — primary hardness contributor), Ordovician Trenton Limestone (highly calcareous — secondary contributor), and Quaternary Grand River alluvium (calcareous — TDS contributor).
At 216 mg/L with TDS 532, Grand Haven's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 12.0 ppt is very high — a certified filter with PFAS removal is strongly recommended — the Ottawa County west Michigan industrial (including former Naval Air Station Muskegon area legacy) contributes to Grand Haven's very elevated PFAS readings.
Geology & Source: Grand Haven in Ottawa County draws from the Grand Haven Water on the Grand River (Ottawa County, west-central Michigan) — the Grand River at Ottawa County drains Silurian Niagaran Dolomite (highly dolomitic) and Ordovician Trenton Limestone (highly calcareous) — Michigan Ottawa County Grand River Silurian dolomitic supply produces very hard water at 216 mg/L with TDS 531.5 mg/L.
