Water Quality Reports

Safe drinking water is treated water that has been tested for harmful and potentially harmful substances and has met or exceeded drinking water quality standards set by the U.S. Environmental Protection Agency (EPA) and the State of Iowa. The EPA sets drinking water standards to define the limits of contaminants considered safe for drinking water. These levels are based on studies of the health effects associated with each contaminant and include a sufficient safety margin to ensure that water meeting these standards is safe for nearly everyone to drink.

These annual water quality reports (Consumer Confidence Reports) are your guide to the quality and safety of tap water provided by Des Moines Water Works. Des Moines Water Works encourages customers to stay informed on your drinking water system. If you have any questions about your drinking water, please contact Des Moines Water Works at (515) 283-8700.
