MESCAL LAKES WATER SYSTEM is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, serving 1,390 people from groundwater.
As of August 1, 2026, its federal record holds 17 entries between 1979 and 2004, all of which EPA lists as closed. Nothing has been added since 2004.
Of the 17, 15 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, volatile organic chemicals, and the Total Coliform Rules.
