The Minnesota Pollution Control Agency (MPCA) and Minnesota Department of Health (MDH) continue to sample private residential wells, municipal wells, and non-community public wells (e.g., small businesses, churches, schools) in the East Metro area for per- and polyfluoroalkyl substances (PFAS). Areas where sampling has taken place:
- Afton
- Cottage Grove
- Denmark Township
- Grey Cloud Island Township
- Lake Elmo
- Lakeland
- Lakeland Shores
- Maplewood
- Newport
- Oakdale
- St. Paul Park
- West Lakeland Township
- Woodbury
Use our interactive map to see where the MPCA and MDH have sampled private wells.
Wells tested and identified with a green symbol showed no or low levels of PFAS. Wells tested and marked with a blue symbol are those wells that have received a health advisory from MDH.
Sampling of eligible private wells is performed at no cost to the homeowners under the Settlement (see part 10.1.2 of the Conceptual Drinking Water Supply Plan). For private wells that are eligible for treatment, the MPCA will continue to manage the installation and maintenance of point-of-entry treatment systems (POETS) using contractors.
If your property is within one of the affected communities listed above, and you have a private drinking water well, you can request to have your water tested using our online form.
How the state decides where to monitor
Private wells are selected for sampling and monitoring mainly based on the following criteria:
- how close they are to known PFAS sources.
- understanding of the geology and how groundwater is moving.
- previous sampling results.
Well sampling is the most intensive — meaning all or most of the wells in that area are sampled most frequently — in areas where:
- PFAS concentrations are the highest.
- the geology is complicated by subsurface features.
- PFAS distribution patterns are unpredictable or concentrations are increasing over time.
Reports on well sampling:
- Older reports in this series are in the Legislative Reference Library collection.
What if my property is outside the affected East Metro communities?
If your property is outside the affected East Metro communities, you can contact a private lab and pay to have your water tested. Please note that MPCA and MDH will be glad to help you interpret your results, but no decisions regarding drinking water advisories or a provision of alternate drinking water (such as bottled water, treatment, or connection to city water) will be based on privately collected water samples.
If your sample indicates levels of PFAS that could be of possible health concern, the state will re-sample your water to confirm the results before taking any actions.
To find a certified water testing lab that can accept samples from private wells for PFAS, go to Search for Accredited Laboratories - Environmental Laboratory Accreditation Program.
- Customize search
- Set Category to “Emerging Contaminant”
- Check “Accepts samples from private home owners”
- Contact the lab directly to determine the number of required samples, sample collection, and shipping.
If you choose to test your water independently and have questions about the results, you can contact the MDH at health.hazard@state.mn.us for help.
