Where the water comes from
Chillicothe draws water from 7 wells. 2 smaller public systems such as schools, businesses or campgrounds buy water from Chillicothe.
Annual water quality report
Chillicothe 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.
