What Makes Weatherford's Water Unique?
Local geology and source profile
Weatherford, Oklahoma, in Custer County — a Custer County city adjacent to Clinton and Elk City on the Washita River in west-central Oklahoma — receives its water from the City of Weatherford Water Department, drawing from Crowder Lake impoundment on the Cobb Creek tributary through the west-central Oklahoma distribution.
The hard 227 mg/L hardness and TDS of 472.3 mg/L reflect the Custer County Permian bedrock supply's hard calcareous character — the Permian Rush Springs Formation (a pinkish calcareous sandstone) and the evaporite-bearing Permian Blaine Formation (gypsum-bearing — contributes sulfate and calcium) produce characteristically hard, elevated-TDS water throughout western Oklahoma (compare Clinton OK: 225/465 in Custer County comparable; Elk City OK: 228/475 in Beckham County comparable; Weatherford consistent hard from the same Custer County Washita-Permian calcareous supply). The Washita watershed at Custer County — Permian Rush Springs Formation (calcareous — primary hardness contributor), Permian Blaine Formation (highly calcareous — secondary contributor), and Quaternary Washita alluvium (calcareous — TDS contributor).
At 227 mg/L with TDS 472, Weatherford's water is hard — scale builds notably in water heaters and appliances over months. Quarterly descaling is appropriate. The PFAS level of 4.5 ppt is moderate — a certified drinking water filter provides added protection. Review the City of Weatherford's annual water quality report for the latest contaminant data.
Geology & Source: Weatherford in Custer County draws from the City of Weatherford Water on Crowder Lake (Custer County, west-central Oklahoma) — the Washita watershed at Custer County drains Permian Rush Springs Formation (calcareous) and Permian Blaine Formation (highly calcareous) — Oklahoma Custer County Crowder Lake Permian calcareous supply produces hard water at 227 mg/L with TDS 472.3 mg/L.
