Buys water from

Annual water quality report

Mobile City 3 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 Mobile City 3 for a copy.

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 Montana.
