Where the water comes from
Montezuma Rimrock Water Company draws water from 2 wells.
Annual water quality report
Montezuma Rimrock Water Company 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 Montezuma Rimrock Water Company 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 Arizona.
