ROBERTS TRAILER PARK is one of 486 community water systems in Wyoming in the 500 or fewer people size category, formerly serving 20 people from groundwater.

EPA's federal records list this system as inactive in 2023; the record below is historical.

As of August 1, 2026, its federal record holds 26 entries between 1976 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 26, 24 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 synthetic organic chemicals.
