What is the Drinking Water Violations Dashboard?
The Drinking Water Violations Dashboard (DVD) identifies public water systems within the United States that have violated EPA National Drinking Water regulation since 2020. This interactive dashboard provides users with the ability to export, visualize, analyze, and filter the drinking water violation data. The purpose of the DVD is to connect non-compliant public drinking water systems with solution providers.
