Water Tests
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 annually for coliform bacteria, and every other year for nitrates. If there is a new infant in the home, the water should also be tested for nitrates.  The Department of Public Health and Environment provides well water testing services to county residents for a modest fee. To order a test kit, call or email the department. All water to be tested must be in the container provided.

Special Water Test Fees for PFCs and VOCs
The department offers special testing for perfluorochemicals (PFCs) and volatile organic compounds (VOCs) (including trichloroethylene or TCE).

Call the department at 651-430-6655 and a Sampling Request Form will be mailed or emailed to you. A PFC sample is $394, and a VOC sample is $230. 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.
 
For the PFC test, your water sample will be tested for the following:
  • Perfluorobutane sulfonate (PFBS)
  • Perfluorobutanoic acid (PFBA)
  • Perfluoropentanoic acid (PFPeA)
  • Perfluorohexane sulfonate (PFHxS)
  • Perfluorohexanoic acid (PFHxA)
  • Perfluorooctane sulfonate (PFOS)
  • Perfluorooctanoic acid (PFOA)
