What Makes Logansport's Water Unique?
Local geology and source profile
Logansport, Indiana, in Cass County — the Cass County seat adjacent to Peru and Kokomo on the Eel River at its confluence with the Wabash River in north-central Indiana — receives its municipal water from the Logansport Water Division, drawing from the Eel River or the Wabash River (Cass County) through the Logansport treatment plant.
The moderately hard 143 mg/L hardness and TDS of 239.5 mg/L reflect the north-central Indiana Till Plain Wabash watershed carbonate character — similar to other Wabash corridor cities (Huntington IN, Wabash IN). The Eel-Wabash system drains the Indiana Till Plain — Silurian Niagara Dolomite and Devonian Onondaga Limestone (calcareous carbonate platform), and calcareous Pleistocene Woodfordian and Illinoian glacial till (ground-up dolomite and limestone — significant dissolved carbonate). The combination of Silurian carbonate bedrock and calcareous till produces the characteristically moderate hardness.
At 143 mg/L, Logansport'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 4.2 ppt warrants a certified drinking water filter — the Cass County agricultural drainage (PFAS from field applications), the Wabash River industrial legacy, and the north-central Indiana PFAS background contribute to Logansport's readings.
Geology & Source: Logansport in Cass County draws from the Logansport Water Division on the Eel River and Wabash River (Cass County, north-central Indiana) — the Eel-Wabash drains the Indiana Till Plain (Silurian Niagara Dolomite, calcareous Pleistocene Illinoian-Woodfordian till) — Indiana Wabash River Silurian dolomite-Pleistocene till watershed produces moderately hard water at 143 mg/L with TDS 239.5 mg/L in this Cass County Indiana city.
