Where the water comes from

Cleveland Municipal Authority draws water from 1 surface water intake. It also buys water from Lone Chimney Water Association.

Buys water from

Annual water quality report

Cleveland Municipal Authority 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.

Find a posted report with EPA's Consumer Confidence Report search

Testing your own water

To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by Oklahoma.
