CEDAR RIVER TRAILER PARK is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 53 people from groundwater.

EPA's federal records list this system as inactive in 2024; the record below is historical.

As of August 1, 2026, its federal record holds 10 entries between 1977 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.

Of the 10, 3 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, the Radionuclides and Revised Rad Rule, and the Consumer Confidence Rule.
