Drinking Water Program

The St. Croix County Community Development Department offers various programs throughout the year that provides residents with opportunities to test their private well water. Participation is voluntary and programs are developed to make testing convenient and ensure residents are working with State Certified Laboratories (PDF). Additionally, well owners learn about their drinking water and things that you can do to keep their water supply healthy.

Residents living in rural areas are encouraged to test their drinking water annually for certain contaminants like coliform bacteria. Often times a family may have no idea what is happening with their drinking water because some contaminants have no taste, odor or color. Their presence can only be determined by testing with state certified laboratories.  

Testing Options

The Community Development Department works directly with the UW-Steven's Point Water & Environmental Analysis Lab and has their water test bottles available for your convenience.
