Where the water comes from
Hartshorne buys its water from Pittsburg Co. Water Authority. It lists no wells or intakes of its own. 1 other community water system buys water from Hartshorne.
Buys water from
- Pittsburg Co. Water Authority McAlester, OK
Community systems that buy water from it
- Jones Academy Durant, OK
Annual water quality report
Hartshorne 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.
