What Makes Hartselle's Water Unique?
Local geology and source profile
Hartselle, Alabama, in Morgan County — a Morgan County city adjacent to Decatur and Lacey's Spring in north Alabama — receives its municipal water from the Hartselle Water Division, drawing from the Flint Creek Reservoir or Tennessee Valley Authority (TVA) reservoir sources (Morgan County) through the north Alabama water treatment system.
The moderately soft 65 mg/L hardness and TDS of 113.1 mg/L are unexpectedly soft for the Tennessee Valley region — much softer than the Tennessee River Scottsboro supply (171 mg/L) — reflecting the Flint Creek Reservoir's more isolated valley catchment with a smaller, more insoluble watershed contributing less calcareous load than the main Tennessee River system. The Flint Creek watershed at Morgan County drains the Tennessee Valley and Ridge — Mississippian Fort Payne Chert (siliceous — near-insoluble dilutant), Pennsylvanian Pottsville Formation (sandstone — near-insoluble), and Mississippian Warsaw Limestone (calcareous — minor hardness contributor at the reservoir catchment).
At 65 mg/L, Hartselle's water is moderately soft — light scale forms slowly in appliances, dishwashers remain efficient, and bathroom fixtures need occasional cleaning. Semi-annual descaling is appropriate. The PFAS level of 4.2 ppt warrants a certified drinking water filter — Redstone Arsenal (Madison County — AFFF) and the north Alabama Tennessee Valley industrial corridor contribute to Hartselle's readings.
Geology & Source: Hartselle in Morgan County draws from the Hartselle Water Division on the Flint Creek Reservoir or Tennessee Valley Authority sources (Morgan County, north Alabama) — the watershed drains the Tennessee Valley and Ridge (Mississippian Fort Payne Chert — calcareous, Ordovician Knox Dolomite) — Alabama Morgan County Tennessee Valley Mississippian calcareous watershed produces moderately soft water at 65 mg/L with TDS 113.1 mg/L.
