Well Water Testing Services

Private well water users should test their water regularly to ensure clean water. The Minnesota Department of Health (MDH) recommends well users test their water for coliform bacteria, nitrate, arsenic, lead, and manganese. The MDH provides well water testing services to county residents for a modest fee.

Protect your health! Test your well water for: Coliform Bacteria every year, Nitrate every other year, Arsenic at least once, Lead at least once, and Manganese before a baby drinks the water. Testing is even more important if young children drink the water.

Per- and Polyfluoroalkyl Substances (PFAS)

Due to the need to prioritize sampling being conducted by Minnesota Pollution Control Agency (MPCA) and Minnesota Department of Health (MDH), the county has suspended fee-for-service PFAS testing. 

Find more information on MDH's response to PFAS. MDH can help you with well testing for PFAS if you are in the sampling area. You can look at the MPCA Interactive Map to see if you are within this area. Please use the MDH Well Sampling Request Form to submit your request.

Volatile organic compounds (VOCs) (including trichloroethylene or TCE) is still currently available. Complete a Sampling Request Form (PDF) and mail form with payment to 14949 62nd Street North, Stillwater, MN 55082.
