PFOA Solution
The chemicals Perfluorooctanoic acid (PFOA), also known as C8, and Perfluorooctane sulfonic acid (PFOS) are bio-permanent, are resistant to direct oxidation, and do not break down naturally in the environment or the human body. Studies suggest that exposure to the chemicals may lead to cancer. The EPA currently marks the unsafe level of PFOA/ PFOS to be above 70 parts per trillion, although some researchers and states believe lower levels are still unsafe. Even 1 ppt may be enough to pose health risks, leading regulators to recommend these chemicals as candidates for the Safe Drinking Water Act.
