HARPER VALLEY TRAILER PARK is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, formerly serving 55 people from groundwater.

EPA's federal records list this system as inactive in 2011; the record below is historical.

As of August 1, 2026, its federal record holds 30 entries between 1992 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.

Of the 30, 22 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 Total Coliform Rules, volatile organic chemicals, and inorganic chemicals.
