Rogers County, Oklahoma: drinking water report. Rogers County northeast of Tulsa has about 92,000 residents in communities including Claremore and Owasso.
Rogers County northeast of Tulsa has about 92,000 residents in communities including Claremore and Owasso. Water comes from Oologah Lake and the Verdigris River, with the Washington County Rural Water District and municipal systems serving different areas. The county's proximity to Tulsa means it catches both suburban growth and the environmental influence of the Tulsa metro area's industrial and military facilities.
Oologah Lake's watershed receives agricultural runoff from across northeastern Oklahoma. According to the Oklahoma Water Resources Board's 2024 lake assessment, total phosphorus in Oologah Lake averaged 0.04 mg/L – at the threshold for algal bloom potential. Summer taste-and-odor events are common as the lake stratifies.
The former Claremore Air National Guard Station has documented AFFF use. Oklahoma DEQ's 2024 PFAS investigation found PFOS at 7 ppt in monitoring wells near the facility. Tulsa International Airport in neighboring Tulsa County also contributes PFAS to the regional groundwater, and the plume may extend into western Rogers County.
Rogers County's rapid suburban growth means water infrastructure is expanding to meet demand. If you are in a newer subdivision on a municipal connection, your system is treated and monitored. Private well owners should test proactively.
Start by checking your water for available data. A carbon filter handles seasonal taste issues from the lake supply. For PFAS, reverse osmosis adds targeted protection. Our water filter guide covers both approaches. Get your detailed report for local data, and visit our Oklahoma page for statewide patterns.
