What Makes Mount Greenwood's Water Unique?
Local geology and source profile
Mount Greenwood, Illinois, in Cook County — a Chicago neighborhood on the far southwest side adjacent to Beverly and Morgan Park, one of the southernmost Chicago neighborhoods bordering the south suburban Cook County — receives its municipal water from the City of Chicago Department of Water Management, drawing from Lake Michigan at the Chicago metropolitan water intake and treatment system.
The moderately hard 168 mg/L hardness and TDS of 326.3 mg/L are in the middle of the Chicago Lake Michigan supply range (West Elsdon: 181 mg/L; Deerfield: 144 mg/L), reflecting the southwest Chicago distribution zone's Lake Michigan supply character. All Chicago neighborhoods receive the same Lake Michigan source, with the Silurian Niagara Dolomite carbonate platform producing the moderately hard water characteristic of the city-wide Chicago Water Management distribution network.
At 168 mg/L, Mount Greenwood's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and bathroom fixtures develop calcium deposits. Quarterly descaling is appropriate. The PFAS level of 5.9 ppt warrants a certified drinking water filter — the Chicago southwest side industrial corridor, the Calumet Region chemical manufacturing belt, and the Chicago Lake Michigan PFAS background contribute to Mount Greenwood's readings.
Geology & Source: Mount Greenwood in Cook County draws from the City of Chicago Water Division on Lake Michigan — Lake Michigan receives drainage from the Great Lakes basin (Silurian Niagara Dolomite, calcareous Pleistocene glacial till) — Lake Michigan Silurian dolomite carbonate drainage produces moderately hard water at 168 mg/L with TDS 326 mg/L in this Cook County Illinois neighborhood.
