Bryant Water Hardness & Quality Report (2026)

Bryant, Arkansas, in Saline County — one of the fastest-growing cities in Arkansas, a Saline County suburb immediately southwest of Little Rock and Benton, part of the Greater Little Rock metropolitan area — receives its municipal water from Bryant Water and Sewer or Central Arkansas Water (CAW), which draws from Lake Maumelle (on the Fourche LaFave River west of Little Rock) or from the Arkansas River — the primary Central Arkansas metropolitan water supplies.

The moderately hard 160.5 mg/L hardness and TDS of 344.5 mg/L reflect the Lake Maumelle-Fourche LaFave watershed's Ouachita Mountains geological character. The Fourche LaFave River drains the Ouachita Mountains — the most distinct topographic feature of central Arkansas, underlain by the Paleozoic Arkansas Novaculite (siliceous chert — extremely resistant siliceous rock that produces soft, acidic runoff), Ordovician Womble Shale, Silurian Blaylock Sandstone, and the Devonian Missouri Mountain Shale. The relatively soft siliceous Ouachita terrain produces moderate hardness, but atmospheric deposition and minor carbonate lenses in the Paleozoic sequence contribute to the 160.5 mg/L reading.

At 160.5 mg/L, Bryant'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 4.7 ppt warrants a certified drinking water filter — Little Rock Air Force Base (Jacksonville, AR — a C-130 transport wing and documented AFFF user in the Saline-Arkansas County watershed), and the Greater Little Rock industrial corridor contribute to Bryant's PFAS readings.
