Perfluorooctanoic acid (PFOA)

Commonfields of Cahokia PWD

NOTE: Commonfields of Cahokia PWD purchases water from IL American - East St. Louis which is required to test for perfluorooctanoic acid (pfoa). Sample information shown below was taken by IL American - East St. Louis.

Perfluorooctanoic acid (PFOA) is a member of a group of perfluorinated chemicals used in many consumer products. PFOA and other perfluorinated chemicals can cause serious health effects, including cancer, endocrine disruption, accelerated puberty, liver and immune system damage, and thyroid changes. These chemicals are persistent in the environment and they accumulate in people. Click here to read more about perfluorinated chemicals.
