PFAS Found in Raleigh Creek

SAINT PAUL, Minn. – Today, the Minnesota Pollution Control Agency announced that PFAS (per- and polyfluoroalkyl substances) have been found in foam along Raleigh Creek. While there has long been PFAS in groundwater and surface water in the east metro, this is the first time that PFAS has been found in surface water foam.

“I am deeply concerned that we continue to see contamination of water in our area with these chemicals,” said Senator Chuck Wiger (DFL-Oakdale). “While we monitor this ongoing situation, I am prepared to work together with my colleagues in the legislature to take action at the state level to address PFAS contamination in our community. We will do whatever is necessary to ensure the safety and wellbeing of the residents of our community.”

In late summer, the MPCA was conducting surface water sampling and observed foam on Raleigh Creek in Oakdale. While most foam found on surface waters is naturally occurring and a result from decomposing plants, this area is located near two PFAS disposal sites therefore the MPCA had the foam samples tested for PFAS.

Recently, the MPCA received confirmation that the foam samples taken from Raleigh Creek had elevated levels of PFAS. Surface water samples collected in the same areas showed much lower levels of PFAS. At this time, Minnesota Department of Health has evaluated the information on PFAS-containing foam on surface water and concluded it does not pose a risk to human health if skin contact with the foam is minor and infrequent.

MDH recommends:

  • People and pets should avoid contact with foam on surface waters in this area.
  • Wash skin that has come into contact with PFAS-containing foam with soap and water.

The MPCA and MDH continue to monitor private drinking water wells in the area, and provide treatment for PFAS if necessary. If you have a private drinking water well which has not yet been tested for PFAS compounds complete the well sample request form at
