What Makes Wixom's Water Unique?
Local geology and source profile
Wixom, Michigan, in Oakland County — an Oakland County city adjacent to Walled Lake and Novi in the west Detroit metro — receives its water from the Great Lakes Water Authority (GLWA), drawing from Lake Huron via the Detroit system (Oakland County) through the west Detroit metro distribution.
The very hard 241 mg/L hardness and TDS of 636 mg/L are significantly harder than the raw Lake Huron supply would suggest (~115 mg/L at the Detroit intake) — reflecting Oakland County groundwater blending or the hard local Silurian dolomite aquifer supplementing the GLWA supply in this west Detroit suburb, producing much harder water than the east Detroit communities (Harper Woods: 114.5 mg/L). This suggests Wixom draws at least partially from a local dolomite groundwater source. The Oakland County supply — local Silurian Niagaran Dolomite (dolomitic — primary hardness contributor from local groundwater), Lake Huron GLWA supply (moderately hard — secondary), and Devonian calcareous formations (calcareous — tertiary contributor).
At 241 mg/L with TDS 636, Wixom'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 13.2 ppt warrants a certified reverse osmosis drinking water filter — Selfridge Air National Guard Base (Macomb County — AFFF) and the Oakland County west Detroit industrial corridor contribute significantly to Wixom's very elevated readings.
Geology & Source: Wixom in Oakland County draws from the Great Lakes Water Authority on Lake Huron via the Detroit system (Oakland County, southeast Michigan) — Lake Huron at Oakland County draws from Silurian Niagaran Dolomite (dolomitic) — Michigan Oakland County Lake Huron Silurian dolomitic Detroit system supply produces very hard water at 241 mg/L with TDS 636 mg/L.
