What Makes Claremore's Water Unique?
Local geology and source profile
The City of Claremore Utilities Department serves approximately 15,873 residents in Claremore, Rogers County, Oklahoma. Water sources include local groundwater wells and purchases from regional providers including RWD #3 Rogers County (Tacora Plant) and Tulsa. Treatment occurs at city-operated facilities, with annual Consumer Confidence Reports (CCRs) published at claremore.com/utilities/city-water-information/. Emergency contacts are 918-341-2066 or 866-345-3734. The utility has historically faced 17 MCL violations per TapWaterData records.
The supply originates in the Verdigris River watershed within the Ozark Plateaus physiographic province. Key aquifers include the Ozark Plateaus aquifer system, recharged by precipitation filtering through Pennsylvanian sandstones, Mississippian limestones like the Boone Formation, and Ordovician dolomites. These soluble carbonate rocks naturally enrich the water with dissolved minerals, yielding a moderately mineralised supply. Karst topography enhances infiltration, blending surface runoff with deep groundwater through limestone dissolution.
Moderately hard water promotes limescale buildup in pipes, water heaters, and dishwashers, reducing efficiency and lifespan. Laundry may feel stiff and soap lathering decreases, requiring more detergent; faucets and washing machines develop spotting. Regular vinegar descaling, installing a water softener, or using scale inhibitors is recommended to mitigate effects and protect household systems. Claremore's water scores a D+ overall per recent assessments, with an F for legal limits compliance and 3 contaminants exceeding EPA health guidelines (MCLGs); residents should review the official CCR at sdwis.deq.state.ok.us.
Geology & Source: Rogers County, NE Oklahoma — Ozark Plateaus aquifer system; Paleozoic limestone and dolomite (Ordovician–Pennsylvanian) including Viola Limestone; karst dissolution imparts moderately hard water

Data Sources & Methodology
Water quality data for Claremore 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.
