The State of Iowa Public Drinking Water Program 2014 Annual Compliance Report is available. The Safe Drinking Water Act (SDWA) Amendments of 1996 require the Department to issue an annual report of the SDWA violations in the state. This report fulfills the reporting requirement in Iowa for the 2014 calendar year and was provided to EPA on July 1st.
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 were from Drinking Water State Revolving Loan Fund projects 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.
