What are Forever Chemicals?

Perfluoroctanoic acid (PFOA) and Perfluorooctane sulfonate (PFOS), also known as Forever Chemicals, are man-made chemicals whose use began in the 1940’s and were used in several areas such as non-stick pans and firefighting foams due to their high stability and low tension properties. It wasn’t until the 2000’s that it was realized these substances are harmful to those who have received exposure. While these chemicals are no longer being manufactured, due to their slow breakdown, they can still be found throughout the environment, including in drinking water. While the contamination is generally minimal, areas where these chemicals were in high use tend to have higher contamination levels than elsewhere.


Due to these chemicals being synthetic with their high stability and not being found in nature, they take more time to break down and can build up in the body's system. While research studies are still being done on their long-term effects, they have been connected to several health risks including cancer.

The EPA Limit in Drinking Water for PFOA is 0.004ppt and for PFOS it is 0.02 ppt.

In Essence, the EPA Wants the Limits to be as Close to Zero as Possible, due to how Dangerous these Compounds are.

Enalytic can offer analysis on a number of matrices. We can develop methods for analysis where one does not exist.

Some of the Many Compounds we can Test for Include the Following:

1H, 1H, 2H, 2H-perfluorodecane sulfonic acid (8:2FTS)

1H, 1H, 2H, 2H-perfluorooctane sulfonic acid (6:2FTS)
