Closed: East Metro PFAS forensics

The Minnesota Pollution Control Agency (MPCA) is seeking proposals from qualified responders to conduct an environmental forensics evaluation using non-targeted analysis (NTA) techniques for identifying sources of non-aqueous film forming foam (non-AFFF) per- and polyfluoroalkyl substances (PFAS) contamination in water for the purpose of better understanding extent and magnitude of releases in the subject areas.

Information regarding PFAS forensics and source identification can be found on the PFAS document developed by the Interstate Technology & Regulatory Council (ITRC):

• Forensics and source identification
• Source identification

The goal of this project is to conduct an environmental forensics evaluation using NTA techniques to provide better understanding and documentation of the following:

• extent and magnitude of releases in the subject areas
• primary differences between samples collected from the source areas and in the areas of contaminant commingling
• specific analytes outside of those analyzed for in the U.S. Environmental Protection Agency (EPA) Method 1633 that could be used to determine the extent of PFAS impacts resulting from each source area

Closed: Responses were due May 12, 2026
