Where the water comes from
Barnsdall draws water from 1 surface water intake. 1 other community water system buys water from Barnsdall.
Community systems that buy water from it
- Osage Co RWD # 5 Barnsdall, OK
Annual water quality report
Barnsdall must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.
Where the state allows it, systems serving fewer than 10,000 people may publish the report in a local newspaper or news site instead of mailing it, and must provide a copy on request.
