What Makes Malvern's Water Unique?
Local geology and source profile
Malvern, Arkansas, in Hot Spring County — the Hot Spring County seat adjacent to Benton and Hot Springs on the Ouachita River in central Arkansas — receives its water from the City of Malvern Water Department, drawing from the Ouachita River through the central Arkansas distribution.
The soft 67 mg/L hardness and low TDS of 108.9 mg/L reflect the Hot Spring County Ouachita River supply's soft Ouachita Mountains character — the Ordovician Womble Shale is largely insoluble black shale, while the Mississippian Stanley Formation contributes minimal calcareous mineral content from its slightly calcareous shale and sandstone (compare Benton AR: 64/103 in Saline County comparable; Hot Springs AR: 69/114 in Garland County comparable; Malvern consistent soft from the same Hot Spring County Ouachita River Ordovician insoluble supply). The Ouachita watershed — Ordovician Womble Shale (insoluble — primary dilutant), Mississippian Stanley Formation (slightly calcareous — primary hardness contributor), and Quaternary Ouachita alluvium (slightly calcareous — minor TDS).
At 67 mg/L with TDS 109, Malvern's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 2.9 ppt is low — a clean result for central Arkansas. Review the City of Malvern's annual water quality report.
Geology & Source: Malvern in Hot Spring County draws from the Malvern Water on the Ouachita River (Hot Spring County, central Arkansas) — the Ouachita watershed at Hot Spring County drains Ordovician Womble Shale (insoluble) and Mississippian Stanley Formation (slightly calcareous) — Arkansas Hot Spring County Ouachita River Ordovician insoluble supply produces soft water at 67 mg/L with TDS 108.9 mg/L.
