LONG BRANCH MAINTENANCE CORP. is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 350 people from groundwater.

EPA's federal records list this system as inactive in 2007; the record below is historical.

As of August 1, 2026, its federal record holds 14 entries between 1995 and 2001, all of which EPA lists as closed. Nothing has been added since 2001.

Of the 14, 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 inorganic chemicals, the Radionuclides and Revised Rad Rule, and the Total Coliform Rules.
