Supervisor, Source Water Protection Unit
SUBJECT: Statewide Perfluoroalkyl Substances (PFAS) Monitoring Project
Below please find your system's sampling results for the Statewide PFAS Monitoring Project.
Sampling was conducted on 11/14/21.
Sampling results
PFAS contaminant detected
Maximum
concentration (µg/L)1
PFBA 0.0014
MDH health value
(µg/L)
All sampling results were below the available health -based guidance values for PFAS. A person
drinking water at or below the guidance value would have little or no risk for health effects.
Next Steps
Since PFAS sampling is not required by the EPA, you are not required to include these results in
your consumer confidence report (CCR). However, MDH recommends that you include them in
your next CCR and can provide resources to help you give context about what these results
mean.
About the project
Minnesota Department of Health (MDH) has been studying the potential health impacts of
PFAS in groundwater in Minnesota since 2002. This project is part of a larger effort at MDH to
sample all community water systems (CWSs) for PFAS. MDH aims to cover 90% of CWS
customers under its PFAS monitoring program by 2025. The project has been made possible
through funding from the Clean Water Fund and U.S. Environmental Protection Agency.
Sampling results from all systems that participated in the study will be included in an interactive
mapping application on the MDH website. MDH will also be providing these results to the
Minnesota Pollution Control Agency to make them aware of the contamination.
1 One microgram per liter is the same as one part per billion (ppb).
