The report was compiled by the staff of the Iowa Department of Natural Resources' Water Supply Engineering and Operations Sections, using data collected in 2019 from all active public water supplies in the state. The report contains a summary of the program, a description of the requirements that systems must meet, the year’s violation statistics, and the list of the systems with each health-based standard or major monitoring or reporting violation incurred during the year.
The photographs in the report are from Drinking Water State Revolving Loan Fund projects, primarily those that were completed during the year. The maps depict the public water supply system universe in Iowa and the locations of the systems that incurred the health-based standards and major monitoring and reporting violations. The maps are also separately listed on the website.
Iowa had 1,855 active public water supply systems in 2019. Of those systems, 95.5% were in compliance with all health-based drinking water standards, and 82.8% were in compliance with all major monitoring and reporting requirements. There were no waterborne disease outbreaks or deaths attributed to the drinking water at any active public water supply in Iowa during the year.
