ROYAL CREST TRAILER COURT is one of 667 community water systems in New Mexico in the 500 or fewer people size category, formerly serving 500 people from groundwater.
EPA's federal records list this system as inactive in 1984; the record below is historical.
As of August 1, 2026, its federal record holds 8 entries between 1980 and 1982, all of which EPA lists as closed. Nothing has been added since 1982.
All 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.
