Where the water comes from

Decker Hills draws water from 6 wells. 1 smaller public system such as schools, businesses or campgrounds buys water from Decker Hills.

Annual water quality report

Decker Hills 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.
