What Makes Calera's Water Unique?
Local geology and source profile
Calera, Alabama, in Shelby County — a Shelby County city adjacent to Montevallo and Alabaster on the Coosa River system in north-central Alabama — receives its water from the Shelby County Water Authority, drawing from Lay Lake (Shelby County) through the north-central Alabama distribution.
The very soft 36 mg/L hardness and TDS of 54.3 mg/L reflect the north-central Alabama Shelby County Coosa River supply's very soft character — the upper Coosa watershed's Precambrian Hillabee Greenstone and Cambrian Shady Dolomite produce low-mineral runoff through the Alabama Ridge and Valley, with the Lay Lake impoundment diluting the minimal calcareous input to produce near-pure water typical of the upper Alabama River system. The Coosa-Lay Lake watershed at Shelby County — Precambrian Hillabee Greenstone (insoluble — primary dilutant), Cambrian Shady Dolomite (slightly calcareous — minor hardness contributor), and Ordovician Knox Dolomite (slightly calcareous — secondary minor).
At 36 mg/L, Calera's water is very soft — no scale buildup in appliances, dishwashers remain efficient, and no softening is needed. Water is ideal for all uses. The PFAS level of 3.2 ppt warrants a certified drinking water filter — the Shelby County north-central Alabama industrial corridor contribute to Calera's readings.
Geology & Source: Calera in Shelby County draws from the Shelby County Water Authority on Lay Lake (Shelby County, north-central Alabama) — the Coosa River-Lay Lake watershed at Shelby County drains the Valley and Ridge (Cambrian Shady Dolomite — slightly calcareous) and Precambrian Hillabee Greenstone (insoluble) — Alabama Shelby County Coosa-Lay Lake Cambrian-Precambrian slightly calcareous supply produces very soft water at 36 mg/L with TDS 54.3 mg/L.
