What Makes Berkley's Water Unique?
Local geology and source profile
Berkley, Michigan, in Oakland County — an Oakland County city adjacent to Royal Oak and Huntington Woods in the north Detroit suburb — receives its water from the Great Lakes Water Authority (GLWA), drawing from Lake Huron (southeast Michigan) through the Detroit metro distribution network.
The hard 160.5 mg/L hardness and TDS of 332.2 mg/L reflect the southeast Michigan GLWA Lake Huron supply's moderate calcareous character — consistent with other GLWA-served Oakland County communities (Royal Oak: ~158 mg/L; Hazel Park: ~162 mg/L). Lake Huron at the GLWA intake receives drainage from the Great Lakes Basin — Silurian Niagara Dolomite (dolomite — primary hardness and TDS contributor at the Michigan Lake Huron basin), Devonian Hamilton Formation (calcareous shale — secondary contributor), and Mississippian formations (calcareous). The Silurian Niagara dolomite dissolution produces the hard southeast Michigan supply.
At 160.5 mg/L, Berkley's water is hard — scale builds steadily in kettles and appliances, dishwashers benefit from rinse aid, and water heaters should be descaled annually. Monthly descaling is recommended. The PFAS level of 9.1 ppt warrants a certified reverse osmosis drinking water filter — Wurtsmith Air Force Base (Iosco County — AFFF, a major Michigan PFAS source), Selfridge Air National Guard Base (Macomb County — AFFF), and the southeast Michigan industrial PFAS complex (Detroit automotive corridor) contribute to Berkley's elevated readings.
Geology & Source: Berkley in Oakland County draws from the Great Lakes Water Authority on Lake Huron (Oakland County, southeast Michigan) — Lake Huron at the GLWA intake receives drainage from the Great Lakes Basin (Silurian Niagara Dolomite, Devonian Hamilton Formation — calcareous) — Michigan Oakland County Lake Huron Silurian-Devonian calcareous watershed produces hard water at 160.5 mg/L with TDS 332.2 mg/L.
