How do you know if your water utility has tested for PFAS?

There are number of things you can do to find out if your water utility has tested: 

Contact your local officials, including the head of your water utility

You deserve full transparency about what's in your drinking water. Ask if your water utility has conducted comprehensive testing for PFAS. If some level of testing has been done, ask to see all the results.


Visit the DNR's website

The Wisconsin Department of Natural Resources (DNR) has a voluntary sampling program for communities that are interested in testing their water for PFAS. All results of samples taken as a part of this voluntary testing program are available online to the public and available under "PFAS Contaminant Sample Results".

Visit the EPA's website

Between 2013 and 2015, the EPA required some utilities in Wisconsin to test for PFAS under the Unregulated Contaminant Monitoring Rule (UCMR3). The EPA uses the Unregulated Contaminant Monitoring Rule (UCMR) to collect data every five years for contaminants that are suspected to be present in drinking water and do not have health-based standards set under the Safe Drinking Water Act. You can search for test results here.

File a public records request

If you have reason to believe local officials are withholding information, you may need to submit a public records request to obtain the information you're asking for. Midwest Environmental Advocates' Open Government Guide can help.
