PFC Detection in Monitoring Wells

Perfluorinated compounds (PFCs) have been classified by the U.S. Environmental Protection Agency as an emerging contaminate on the national landscape.  PFCs are a class of man-made chemicals that were introduced in the 1950s to make products that resist heat, stains, grease and water. For example, PFCs may be used to keep food from sticking to cookware, to make sofa cushions and carpets that are resistant to stains, to make clothes and mattresses that repel water, and in food packaging like pizza boxes and airtight bags. And because they help reduce friction, they are widely used in a variety of other industries including aerospace, automotive, building and construction, and electronics.

One of the most prolific uses of the chemicals is a powerful fire-suppression foam that efficiently douses even the most combustible (and most dangerous to life and property) Class B, flammable liquid, fuel fires. Virtually every airport (public, private, military and civilian) and every fire-fighting squad in the world is familiar with the aqueous film-forming foam (AFFF) and can attest to its effectiveness.

The Camp Grayling environmental staff regularly monitor a number of environmental factors at the camp and airfield to ensure safety, compliance with state and federal regulations, and to proactively detect and remedy potential problems.  The most recent proactive measure was to test water samples for PFCs. A few of the samples  detected the compound at levels above EPA guidance. The Michigan National Guard and Michigan Department of Military and Veterans Affairs, along with state and local environmental experts and officials want to share the testing information and information about this family of chemicals in general, with members of the Grayling community and anyone else looking for information on this topic.

Residents please note:

Many residents have inquired about which whole house filters are certified to remove PFOS/PFOA.  At this time, the DEQ is not aware of any whole house filters currently on the market that are certified to remove PFOS/PFOA by the NSF International.
