What Makes Moore's Water Unique?
Local geology and source profile
City of Moore Public Utilities serves approximately 60,000 residents in Cleveland County, Oklahoma, south of Oklahoma City. Water is sourced from 34 active groundwater wells tapping the Garber-Wellington aquifer, supplemented by purchases from Oklahoma City (sourced from Lake Hefner). Storage includes 5 water towers and one ground storage tank, distributed via 273 miles of water lines. Treatment and operations are managed by Veolia Water, with quality testing conducted continuously and reported annually via the Consumer Confidence Report (CCR).
Moore's water originates from the Garber-Wellington aquifer in the Arkansas River watershed, where Permian bedrock formations dissolve minerals into the groundwater. The aquifer's Wellington Formation and Garber Sandstone — comprising limestone, dolomite, and sandstone layers — contribute a hard supply character through prolonged contact with calcium and magnesium-bearing rocks. Karst-like aquifer features and recharge from surface precipitation further shape the elevated mineral content without softening influences.
Hard water in Moore leads to scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. White deposits on fixtures and reduced soap lathering are common; regular deliming and cleaning aerators is advised, and a water softener is recommended. The 2025 CCR notes violations for chlorine, sodium, and radionuclides, with naturally occurring arsenic, uranium, fluoride, and chromium-6 detected within EPA MCLs. Treatment includes chlorine/chloramine disinfection; reverse osmosis is recommended for additional contaminant reduction.

Data Sources & Methodology
Water quality data for Moore is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.
Water Hardness
Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city — the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.
pH
Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.
TDS — Total Dissolved Solids
Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.
PFAS — Perfluoroalkyl and Polyfluoroalkyl Substances
EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) — sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.
Lead
Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age — all estimates are maintained below the EPA action level of 0.015 mg/L.
Appliance Lifespan
Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
