WESTLAKE MHP is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 350 people from surface water.

EPA's federal records list this system as inactive in 2019; the record below is historical.

As of August 1, 2026, its federal record holds 11 entries between 2007 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

Of the 11, 6 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 Lead and Copper Rule, the Consumer Confidence Rule, and the Total Coliform Rules.
