LAS TUSAS MDWCA is one of 667 community water systems in New Mexico in the 500 or fewer people size category, formerly serving 20 people from groundwater.
EPA's federal records list this system as inactive in 2009; the record below is historical.
As of August 1, 2026, its federal record holds 10 entries between 1992 and 2009, all of which EPA lists as closed. Nothing has been added since 2009.
Of the 10, 4 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, the Public Notice Rule and Revised PN Rule, and the Consumer Confidence Rule.
