WINTERHAVEN MDWC AND SWA is one of 667 community water systems in New Mexico in the 500 or fewer people size category, serving 147 people from groundwater.

As of August 1, 2026, its federal record holds 16 entries between 1991 and 2011, all of which EPA lists as closed. Nothing has been added since 2011.

Of the 16, 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 volatile organic chemicals, the Total Coliform Rules, and the Lead and Copper Rule.
