PFA Contamination



PFA's also known as PFC's are polyfluoroalkyl and perfluorinated chemicals or substances such as perfluoroctanoic acid (PFOA), perfluorooctanesulfonic acid or perfluorooctane sulfonate (PFOS) that are toxic to humans and have been used by industries across Michigan without proper oversight for decades.  Once ingested these chemicals stay in the blood and is found in at minimum 2% of fish in tested Michigan waterways.  We are currently paying very close attention to local communities that are investigating cancer clusters around the state and their relation to these toxic chemicals.
