What Makes Trenton's Water Unique?
Local geology and source profile
Trenton, Michigan, in Wayne County — a Wayne County city adjacent to Riverview and Gibraltar on the Detroit River in the Downriver Detroit metro, a south Wayne County suburban community — receives its municipal water from the Great Lakes Water Authority (GLWA), drawing from Lake Erie or the Detroit River at the GLWA southeast Michigan water system serving the Downriver communities.
The hard 224.5 mg/L hardness and high TDS of 566.4 mg/L are among the highest for the Downriver Detroit metro — harder than central Detroit (typically 150-180 mg/L), possibly reflecting the southeast Wayne County distribution zone's characteristics or seasonal Lake Erie-Detroit River variation. The Silurian Niagara Dolomite and Devonian Detroit River Group limestone carbonate platform drainage is the primary hardness source for all southeast Michigan Lake Erie communities.
At 224.5 mg/L, Trenton's water is hard — scale builds rapidly in appliances and plumbing. A water softener is strongly recommended. The PFAS level of 12.4 ppt is very elevated and warrants a certified reverse osmosis drinking water filter — the Downriver Detroit industrial corridor (Trenton Channel Power Plant — heavy industrial PFAS legacy), Selfridge Air National Guard Base (AFFF in the Lake Erie-Detroit River watershed), and the Wayne County-Lake Erie industrial PFAS complex contribute to Trenton's very elevated readings.
Geology & Source: Trenton in Wayne County draws from the Great Lakes Water Authority on Lake Erie or the Detroit River (Wayne County, southern Detroit metro) — Lake Erie-Detroit River receives drainage from the Great Lakes basin (Silurian Niagara Dolomite, Devonian Detroit River Group limestone) — Lake Erie-Detroit River Silurian-Devonian dolomite carbonate drainage produces hard water at 224.5 mg/L with high TDS 566 mg/L in this Wayne County Michigan city.
