What Makes Worth's Water Unique?

Local geology and source profile

Source: RiverTDS: 686 mg/LpH: 8.5

Worth, Illinois, in Cook County β€” a Cook County village adjacent to Palos Hills and Alsip in the south Chicago suburbs β€” receives its water from the Village of Worth or Illinois American Water, drawing from Lake Michigan through the northeast Illinois distribution.

The very hard 266 mg/L hardness and high TDS of 686 mg/L reflect the Cook County supply's very hard dolomitic character β€” the Silurian Niagaran Dolomite and Devonian Dundee Limestone are highly dolomitic formations in the Illinois Dolomite Plateau, and the south Cook County supply zone concentrates dissolved mineral content from the dolomite aquifer blending with Lake Michigan supply (compare Palos Hills IL: 262/675 in Cook County comparable; Alsip IL: 269/697 in Cook County comparable; Worth consistent very hard from the same Cook County Lake Michigan Silurian dolomitic supply). The Lake Michigan supply at Cook County β€” Silurian Niagaran Dolomite (highly dolomitic β€” primary hardness contributor), Devonian Dundee Limestone (calcareous β€” secondary contributor), and Quaternary Cook County glacial till (calcareous β€” TDS contributor).

At 266 mg/L with TDS 686, Worth's water is very hard β€” a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 9.3 ppt is very elevated β€” a certified filter with PFAS removal is strongly recommended. Review the Village of Worth's annual water quality report.
