What Makes Maumelle's Water Unique?
Local geology and source profile
Maumelle, Arkansas, in Pulaski County — a Pulaski County city adjacent to Little Rock and North Little Rock on the Arkansas River at Lake Maumelle, one of the largest planned cities in Arkansas — receives its municipal water from Central Arkansas Water (CAW), drawing from Lake Maumelle (Maumelle River, Pulaski County) through the CAW treatment plant.
The moderately hard 101 mg/L hardness and TDS of 183.1 mg/L reflect the Lake Maumelle-Ouachita Mountain watershed's relatively insoluble Paleozoic character. Lake Maumelle receives the Maumelle River drainage from the Ouachita Mountains — Ordovician Bigfork Chert (insoluble siliceous), Ordovician Womble Shale (slightly calcareous), and Pennsylvanian Hartshorne Sandstone (insoluble). The predominantly insoluble Ouachita Paleozoic chert and sandstone produce the moderately soft-to-hard water characteristic of the Central Arkansas Water supply.
At 101 mg/L, Maumelle's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 3.5 ppt warrants a certified drinking water filter — the Little Rock Air Force Base (Lonoke County — AFFF in the Arkansas River-Maumelle watershed), the Pulaski County industrial corridor, and the central Arkansas PFAS background contribute to Maumelle's readings.
Geology & Source: Maumelle in Pulaski County draws from Central Arkansas Water on the Maumelle River watershed (Lake Maumelle, Pulaski County) — the Maumelle drains the Ouachita Mountains (Ordovician Bigfork Chert, Pennsylvanian Hartshorne Sandstone) and the Arkansas Valley — Arkansas Pulaski County Ouachita Mountains insoluble watershed produces moderately hard water at 101 mg/L with TDS 183.1 mg/L in this Pulaski County Arkansas city.
