What Makes Burr Ridge's Water Unique?
Local geology and source profile
Burr Ridge, Illinois, in DuPage County — a DuPage County village adjacent to Hinsdale and Darien in the west Chicago suburbs — receives its water from the DuPage Water Commission, drawing from Lake Michigan through the northeast Illinois distribution.
The very hard 257.5 mg/L hardness and high TDS of 650 mg/L reflect the DuPage County supply's very hard dolomitic character — the Silurian Niagaran Dolomite and Ordovician Galena Dolomite are highly dolomitic formations in the Illinois Dolomite Plateau, and DuPage County well fields penetrate these formations to produce some of the hardest water in the Chicago metro (compare Hinsdale IL: 253/639 in DuPage County comparable; Darien IL: 261/661 in DuPage County comparable; Burr Ridge consistent very hard from the same DuPage County Lake Michigan Silurian dolomitic supply). The DuPage County supply — Silurian Niagaran Dolomite (highly dolomitic — primary hardness contributor), Ordovician Galena Dolomite (highly dolomitic — secondary contributor), and Quaternary DuPage County glacial till (calcareous — TDS contributor).
At 257.5 mg/L with TDS 650, Burr Ridge's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 9.0 ppt is very elevated — a certified filter with PFAS removal is strongly recommended. Review DuPage Water Commission's annual water quality report.
Geology & Source: Burr Ridge in DuPage County draws from the DuPage Water Commission on the Lake Michigan supply (DuPage County, northeast Illinois) — the DuPage watershed draws from Silurian Niagaran Dolomite (highly dolomitic) and Ordovician Galena Dolomite (highly dolomitic) — Illinois DuPage County Lake Michigan Silurian dolomitic supply produces very hard water at 257.5 mg/L with TDS 650 mg/L.
