Monday’s proposal would revisit health risks from PFAS in sewage sludge used as fertilizer, with EPA opening a 60-day public comment period.
EPA said the Biden-era January 2025 draft overstated danger by leaning on worst-case hypothetical scenarios and failing to reflect more real-world exposure patterns.
The agency’s new guidance offers nonbinding steps to reduce exposure and points utilities and communities to federal financing through the Clean Water State Revolving Fund and WIFIA programs.
The reassessment follows contamination concerns that have spread from soil and crops to livestock, fish and drinking water, including Maine farms forced to dump milk and cull animals.
EPA said major uncertainties remain, underscoring how PFAS-tainted sludge has drawn research funding and scrutiny for years without producing broad federal regulation.

EPA Retreats from Enforceable PFAS Limits in Biosolids: Policy Shift Leaves Food Safety and Public Health at Risk
Overview
In July 2026, the EPA shifted its approach to PFAS in biosolids by issuing non-binding guidance for sewage plant operators, moving away from its earlier, more comprehensive risk assessment that had highlighted health risks from PFAS exposure. This change reflects the current administration’s broader push for deregulation, including scaling back proposed PFAS drinking water standards and approving new PFAS-containing pesticides for farmland. Political and legal pressures, such as congressional attempts to limit EPA investigations, played a key role in this policy shift. As a result, enforceable federal standards are lacking, leaving states and communities to navigate PFAS risks on their own.
