SWALEDALE WATER SUPPLY is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, serving 144 people from groundwater.

As of August 1, 2026, its federal record holds 10 entries between 1980 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.

Of the 10, 9 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 synthetic organic chemicals, the Total Coliform Rules, and inorganic chemicals.

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
