WWALS Science Committee Chair Dr. Tom Potter notes, “Finally EPA has recognized the risks of sludge application to farmland.”

Sewage sludge as fertlizer is a widespread problem in Florida.

These forever chemicals as in our rivers in Georgia and Florida. They collect in fish, including in the Alapaha River.

Waterkeeper Alliance encourages Waterkeeper groups to participate in the public comment period, which must be received on or before March 17. Individuals and other groups can also comment.

U.S. EPA recognizes sewage sludge on farmland among human health risk of PFOA and PFOS forever chemicals 2025-01-14

See EPA on Draft Sewage Sludge Risk Assessment for Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonic Acid (PFOS) and https://www.Regulations.gov, EPA-HQ-OW-2024-0504; FRL 12451-01-OW.

SUMMARY:

As part of the Environmental Protection Agency’s (EPA’s) commitment to safeguarding the environment from per- and polyfluoroalkyl substances (PFAS), the agency is announcing the availability of the “Draft Sewage Sludge Risk Assessment for Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonic Acid (PFOS)” for a 60-day public comment period. This draft risk assessment reflects the agency’s latest scientific understanding of the potential risks to human health and the environment posed by the presence of PFOA and PFOS in sewage sludge that is land applied as a soil conditioner or fertilizer (on agricultural, forested, and other lands), surface disposed, or incinerated. The draft risk assessment focuses on those living on or near impacted sites or those that rely primarily on their products (e.g., food crops, animal products, drinking water); the draft risk assessment does not model risks for the general public. This draft risk assessment underwent independent external peer review, and the EPA revised the document accordingly. Once finalized, the risk assessment will provide information on risk from use or disposal of sewage sludge and will inform the EPA’s potential future regulatory actions under the Clean Water Act (CWA).
