System type: Community Water System
Population served: 120
Service connections: 60
Ownership: privately owned
Water source: groundwater (wells)

ACORN ACRES MHP is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 120 people from groundwater.

EPA's federal records list this system as inactive in 2021; the record below is historical.

As of August 1, 2026, its federal record holds 72 entries between 1993 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 72, 65 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, inorganic chemicals, and the Total Coliform Rules.
