SIRWA #3 (OSCEOLA) is one of 91 community water systems in Iowa in the 3,301 to 10,000 people size category, serving 4,080 people from surface water.

As of August 1, 2026, its federal record holds 6 entries between 1999 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.

None of the 6 are monitoring or reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset; these involve water-quality, treatment, or public-notice findings instead. The record involves the Stage 1 Disinfectants and Disinfection Byproducts Rule and the Total Coliform Rules.

What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. 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.
