TACNA WATER MANAGEMENT COMPANY is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, formerly serving 1 people from groundwater.

EPA's federal records list this system as inactive in 2025; the record below is historical.

As of August 1, 2026, its federal record holds 45 entries between 1980 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 45, 40 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 Lead and Copper Rule.
