What Makes Lindenhurst's Water Unique?
Local geology and source profile
Lindenhurst, Illinois, in Lake County — a Lake County village adjacent to Waukegan and Lake Villa in northeast Illinois near the Wisconsin border — receives its water from Lake County utilities drawing from Lake Michigan (Lake County) through the northeast Illinois distribution.
The moderately hard 146 mg/L hardness and TDS of 262.7 mg/L reflect the northeast Illinois Lake Michigan supply's moderate Silurian-Ordovician dolomitic character — softer than the central Illinois communities (Chicago Ridge: 173 mg/L) due to the northern Lake County position where the Lake Michigan supply draws from a slightly more diluted northern basin. The Lake Michigan watershed at Lake County — Silurian Niagara Dolomite (dolomitic — primary hardness contributor), Ordovician Galena Dolomite (dolomitic), Ordovician Maquoketa Shale (slightly calcareous), and Cambrian St. Croix Formation (slightly calcareous).
At 146 mg/L, Lindenhurst's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 5.2 ppt warrants a certified drinking water filter — Great Lakes Naval Training Center (Lake County — AFFF) and the northeast Illinois Lake County industrial corridor contribute to Lindenhurst's readings.
Geology & Source: Lindenhurst in Lake County draws from the North Shore Water Reclamation District or Lake County utilities on Lake Michigan (Lake County, northeast Illinois) — Lake Michigan receives drainage from the Great Lakes Basin (Silurian Niagara Dolomite — dolomitic, Ordovician Galena Dolomite — dolomitic) — Illinois Lake County Lake Michigan Great Lakes dolomitic watershed produces moderately hard water at 146 mg/L with TDS 262.7 mg/L.
