Welcome to the Iowa Drinking Water Quality Database, a tool to help you find which water system serves your home and view water quality test results.
Water quality data on this site is from community Public Water Systems, and was collected as part of the Safe Drinking Water Act. If you get your water from a private well, please visit the Iowa Well Forecasting System or the Iowa DNR Private Well Tracking System to view water quality information available about your well.
The Center for Health Effects of Environmental Contaminants created and maintains this site. Please contact us if you run in to issues using the site.
