Where the water comes from

Walnut Grove MHC draws water from 1 well.

Annual water quality report

Walnut Grove MHC 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.

Systems serving 500 or fewer people may meet the rule by telling customers the report is available on request, so you may need to ask Walnut Grove MHC for a copy.
