Sea-Tac Airport sits at the intersection of several PFAS risk factors that make the UCMR 6 proposal especially significant for surrounding communities. Airports are **among the highest-risk PFAS contamination sites** in the country. Sea-Tac has historically used AFFF for fire suppression training and emergency response - AFFF contains high concentrations of PFOS and PFOA, the most well-studied PFAS compounds - These chemicals **migrate readily into groundwater** and do not break down naturally./ - The airport sits on a **glacial outwash plain** with highly permeable soils - This geology **accelerates PFAS movement** into groundwater - Surrounding communities including **Burien, Des Moines, SeaTac city, and Tukwila** draw from regional water systems potentially affected - The **Highline Water District** and other local providers serve these communities

  FMeredith Li-Vollmer Leer en Español We’re learning that some chemicals found in common household products are alarmingly toxic. This is the first comic in a series about a group of chemicals known as “Forever Chemicals” or PFAS, short for perfluoroalkyl and polyfluoroalkyl substances.
