TUCSON WATER CORONA DE TUCSON is one of 67 community water systems in Arizona in the 10,001 to 100,000 people size category, serving 10,217 people from groundwater.

As of August 1, 2026, its federal record holds 9 entries between 1985 and 2002, all of which EPA lists as closed. Nothing has been added since 2002.

Of the 9, 8 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 and the Consumer Confidence Rule.

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
