About Tap Water in Mission, SD

This rating indicates that while the water provided by TRIPP COUNTY WATER USER DISTRICT is treated and regulated, there have been notable compliance issues or contaminant detections recently.

A major factor in Mission's high rating is its flawless health-based violation record. Over the past 5 years of EPA tracking, local water systems have recorded zero health-based violations.
