Perfluorooctanoic Acid (PFOA) in Drinking Water

Perfluorooctanoic Acid (PFOA) is a manufactured chemical that belongs to a group of chemicals used to make household and commercial products that resist heat and chemical reactions, and repel oil, stains, grease, and water. These chemicals are widely found in nonstick cookware, stain-resistant carpets and fabrics, water repellant clothing, paper and cardboard food packaging, and fire-fighting foam.

PFOA does not break down easily and therefore stays for a very long time in the environment, especially in water. Its toxicity and persistence in the environment means it is a potential danger to human health and the environment.

The Vermont health advisory level for PFOA in water is 20 parts per trillion (ppt).

PFOA Contamination in Drinking Water Response

In early 2016, the State initiated an investigation and response regarding PFOA-contamination of drinking water wells. For more information about the response, visit our PFOA Environmental Contamination Response page.
