What Makes Woodhaven's Water Unique?
Local geology and source profile
Woodhaven, Michigan, in Wayne County — a Wayne County city adjacent to Flat Rock and Trenton in southeast Michigan — receives its water from the Detroit Water and Sewerage, drawing from the Detroit River or Lake Erie (Wayne County) through the southeast Michigan distribution.
The very hard 248 mg/L hardness and TDS of 666.6 mg/L reflect the southeast Michigan Wayne County Detroit River supply's very hard dolomitic character — the Silurian Niagaran Dolomite and Devonian Detroit River Formation produce very hard dolomitic water throughout the Detroit metro distribution (compare Winnetka IL: 246/602 comparable on the Lake Michigan supply; Woodhaven similar hardness from the Wayne County Detroit River highly dolomitic draw). The Detroit River at Wayne County — Silurian Niagaran Dolomite (highly dolomitic — primary hardness contributor), Devonian Detroit River Formation (calcareous — secondary contributor), and Quaternary Lake Erie glacial drift (calcareous — TDS contributor).
At 248 mg/L with TDS 667, Woodhaven's water is very hard. A water softener is strongly recommended to prevent rapid scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 13.6 ppt is very high — a certified drinking water filter with PFAS removal is strongly recommended — the Wayne County southeast Michigan industrial and automotive corridor contribute to Woodhaven's very elevated PFAS readings.
Geology & Source: Woodhaven in Wayne County draws from the Detroit Water and Sewerage on the Detroit River or Lake Erie (Wayne County, southeast Michigan) — the Detroit River at Wayne County drains the Great Lakes basin (Silurian Niagaran Dolomite — highly dolomitic) and Devonian Detroit River Formation (calcareous) — Michigan Wayne County Detroit River Silurian-Devonian dolomitic supply produces very hard water at 248 mg/L with TDS 666.6 mg/L.
