What Makes Magnolia's Water Unique?
Local geology and source profile
Magnolia, Arkansas, in Columbia County — a Columbia County city adjacent to Waldo and Emerson in the Timberlands of southwest Arkansas — receives its water from the City of Magnolia Water Department, drawing from Lake Erling on the Dorcheat Bayou through the southwest Arkansas distribution.
The soft 61.5 mg/L hardness and low TDS of 98.1 mg/L reflect the Columbia County Lake Erling supply's soft Coastal Plain character — the Cretaceous Tokio Formation is predominantly insoluble sand, and the Tertiary Wilcox Formation contributes only minor calcareous clay minerals to the soft lowland reservoir supply of southwest Arkansas (compare Waldo AR: 59/94 in Columbia County comparable; El Dorado AR: 63/101 in Union County comparable; Magnolia consistent soft from the same Columbia County Lake Erling Cretaceous-Tertiary Coastal Plain supply). The Dorcheat Bayou watershed — Cretaceous Tokio Formation (insoluble — primary dilutant), Tertiary Wilcox Formation (slightly calcareous — primary hardness contributor), and Holocene Coastal Plain alluvium (slightly calcareous — minor TDS).
At 61.5 mg/L with TDS 98, Magnolia's water is soft — minimal scale buildup and excellent appliance longevity. Annual descaling is appropriate. The PFAS level of 2.8 ppt is low — Magnolia enjoys one of the cleaner water profiles in southwest Arkansas. Review the City of Magnolia's annual water quality report for the latest contaminant data.
Geology & Source: Magnolia in Columbia County draws from the Magnolia Water on Lake Erling reservoir (Columbia County, southwest Arkansas) — the Dorcheat Bayou watershed at Columbia County drains Cretaceous Tokio Formation (insoluble) and Tertiary Wilcox Formation (slightly calcareous) — Arkansas Columbia County Lake Erling Cretaceous-Tertiary Coastal Plain supply produces soft water at 61.5 mg/L with TDS 98.1 mg/L.
