DEL RIO MDWCA is one of 667 community water systems in New Mexico in the 500 or fewer people size category, formerly serving 150 people from groundwater.

EPA's federal records list this system as inactive in 2011; the record below is historical.

As of August 1, 2026, its federal record holds 12 entries between 1983 and 2011, all of which EPA lists as closed. Nothing has been added since 2011.

Of the 12, 7 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 the Total Coliform Rules, inorganic chemicals, and the Consumer Confidence Rule.
