HILLSIDE MHP OKLAHOMA CO is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 15 people from groundwater.

EPA's federal records list this system as inactive in 2018; the record below is historical.

As of August 1, 2026, its federal record holds 26 entries between 2013 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.

Of the 26, 19 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, the Total Coliform Rules, and the Consumer Confidence Rule.
