What Makes Claremore's Water Unique?
Local geology and source profile
Claremore, Oklahoma, in Rogers County — the Rogers County seat adjacent to Owasso in northeastern Oklahoma, a historic Route 66 city and birthplace of Will Rogers, in the Verdigris River valley of the Cherokee Nation territory — receives its municipal water from the City of Claremore Water Division, drawing from Claremore Lake on the Verdigris River system or from the Grand Lake (Grand Lake O' the Cherokees — Lake of the Cherokees) supply.
The moderately hard 149.5 mg/L hardness and TDS of 266.9 mg/L reflect the Verdigris River watershed's Oklahoma Ozark margin geology. The Verdigris River in Rogers County drains the Cherokee Plains transition zone between the Ozark Plateau and the Great Plains — terrain underlain by the Pennsylvanian McAlester Formation, Hartshorne Formation, and the Mississippian Boone Formation (Burlington-Keokuk Limestone equivalent — cherty carbonate). The Mississippian limestone chert beds dissolve partially in the Verdigris headwaters, producing the moderately hard water supply typical of the northeastern Oklahoma Cherokee Plains-Ozark border zone.
At 149.5 mg/L, Claremore's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 3.4 ppt warrants a certified drinking water filter — the Tulsa industrial corridor (Rogers County-Tulsa County), the Oklahoma National Guard Camp Gruber (Muskogee County — AFFF user in the Verdigris watershed), and the northeastern Oklahoma PFAS background contribute to Claremore's readings.
Geology & Source: Claremore in Rogers County draws from the Claremore Water Division on Claremore Lake (Verdigris River tributary, Rogers County) or the Grand Lake system — the Verdigris River drains the Ozark Plateau margins and the Cherokee Plains (Pennsylvanian McAlester Shale, Mississippian Burlington Limestone) — Oklahoma Ozark border Mississippian limestone drainage produces moderately hard water at 149.5 mg/L with TDS 267 mg/L in this Rogers County Oklahoma city.
