"The Endocrine Society appreciates the opportunity to provide comments on the designation of PFOA and PFOS as CERCLA hazardous substances. Founded in 1916, the Endocrine Society is the world’s oldest, largest, and most active organization of scientists and healthcare professionals dedicated to research on hormones and the clinical treatment of patients with endocrine diseases. Our membership includes 18,000 clinicians and scientists from over 120 countries, including many researchers engaged in the study of the adverse effects of per- and polyfluoroalkyl substances (PFAS) on endocrine systems. These chemicals have been shown to disrupt the endocrine system in humans; exposure can lead to cancer, thyroid disruption, reproductive difficulties, and other endocrine disorders.
Because of the known adverse effects on the endocrine system, we are writing in support of the designation of PFOA and PFOS as CERCLA hazardous substances. This is an important first step in holding polluters accountable for the release of these toxic substances into the environment."
