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. For more information on MDH’s response, please see this website. 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 and mail form with payment to 14949 62nd Street North, Stillwater, MN 55082. A VOC sample is $175. After you request the test, county staff will come out to your property to take the sample and send it to the MDH Public Health Laboratory for analysis. Results and a description of what they mean will be mailed to you from MDH approximately six to eight weeks from the date of sampling.
