Mustang Water Hardness & Quality Report (2026)

Mustang, Oklahoma, in Canadian County — a fast-growing Canadian County suburb southwest of Oklahoma City in the OKC metro's western sprawl corridor, one of the fastest-growing suburbs in the Oklahoma City metropolitan area — receives its municipal water from the Town of Mustang Water Utility or Oklahoma City water service, drawing from the Oklahoma City reservoir system — Lake Hefner and Lake Overholser (North Canadian River basin) as the primary metropolitan supply.

The moderately soft 82.5 mg/L hardness and TDS of 126.2 mg/L are softer than typical Oklahoma-Anadarko Basin groundwater — reflecting the surface reservoir character of the Lake Hefner-Overholser supply. The North Canadian River above Oklahoma City drains the Anadarko Basin western Oklahoma corridor, passing through terrain underlain by Permian red bed sandstone and shale (the Rush Springs Formation, Garber Sandstone) — relatively low carbonate compared to the Pennsylvanian limestone dominant further east. The Oklahoma City reservoir system produces moderately soft to moderately hard water (80-130 mg/L) throughout the OKC metro area, much softer than the extreme Arkoma Basin groundwater supplies of eastern Oklahoma.

At 82.5 mg/L, Mustang's water is moderately soft — comfortable for household use. Scale forms slowly over many months, soap lathers well, and appliances operate efficiently. Semi-annual descaling is adequate. The PFAS level of 2.6 ppt is very good for the Oklahoma City corridor — Mustang's relatively limited direct military-industrial PFAS sources and the North Canadian River reservoir supply's good watershed protection produce one of the cleaner PFAS readings in the OKC area.
