Environmental concerns with AFFF and PFAS, and how should a transfer station address them?

• A. Use as much foam as possible to ensure extinguishment regardless of environmental impact.
• B. Minimize use, contain spills, prevent discharges to stormwater, isolate waste, and follow disposal/regulatory requirements for PFAS-containing materials.
• C. Discharge directly to stormwater to dilute PFAS in water bodies.
• D. Store PFAS-containing materials near public areas for quick access.

Answer: (B)

When dealing with AFFF and PFAS, the priority is preventing environmental release and staying compliant with regulations, because PFAS are persistent and can contaminate soil and water long after a spill. PFAS-containing foam can spread through spills or runoff and remain in the environment, so the best approach is to minimize foam use, contain spills, prevent discharges to stormwater, isolate waste, and follow disposal and regulatory requirements for PFAS-containing materials. Minimizing use reduces the potential PFAS load in any firefighting or training event. Containing spills with secondary containment and absorbents keeps PFAS from spreading and entering drains or waterways. Preventing discharges to stormwater stops PFAS from being carried off-site and into surface or groundwater. Isolating waste ensures PFAS-containing materials are kept separate, properly labeled, and secured to minimize exposure and cross-contamination. Following disposal and regulatory requirements ensures that PFAS-containing waste is managed in accordance with applicable rules, using approved methods and proper documentation, which may include hazardous waste determination and transfer to permitted facilities. The other options undermine safety and environmental protection: using foam aggressively increases PFAS release, discharging to stormwater to dilute PFAS masks the problem and is often prohibited, and storing PFAS near public areas creates unnecessary risk.
