MESALAND WATER COMPANY is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, serving 294 people from groundwater.
As of August 1, 2026, its federal record holds 15 entries between 1980 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.
Of the 15, 14 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves inorganic chemicals, the Radionuclides and Revised Rad Rule, and the Consumer Confidence Rule.
