What Makes Chesterton's Water Unique?
Local geology and source profile
Chesterton, Indiana, in Porter County — a Porter County town adjacent to Portage and Burns Harbor on the Lake Michigan shore in northwest Indiana — receives its water from Indiana American Water, drawing from Lake Michigan (Porter County) through the northwest Indiana distribution.
The very hard 214.5 mg/L hardness and TDS of 474.5 mg/L are significantly harder than the raw Lake Michigan supply — reflecting Chesterton's position in Porter County where the local supply blends Lake Michigan water with Silurian dolomite deep well supplementation, similar to La Grange Park IL (247.5 mg/L), producing very hard water through the dolomite well contribution. The Porter County supply — local Silurian Niagaran Dolomite deep well (dolomitic — primary hardness contributor), Lake Michigan (moderately hard — secondary supply), and Pleistocene calcareous glacial drift (calcareous — TDS contributor).
At 214.5 mg/L with TDS 474, Chesterton's water is very hard. A water softener is strongly recommended to prevent rapid scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 6.8 ppt warrants a certified drinking water filter — the Porter County northwest Indiana steel-industrial corridor contribute to Chesterton's elevated readings.
Geology & Source: Chesterton in Porter County draws from the Indiana American Water on Lake Michigan (Porter County, northwest Indiana) — Lake Michigan at Porter County draws from Silurian Niagaran Dolomite (dolomitic) glacial outwash through the western Great Lakes watershed — Indiana Porter County Lake Michigan Silurian-Pleistocene dolomitic supply produces very hard water at 214.5 mg/L with TDS 474.5 mg/L.
