PFAS soil testing updates
Soil testing on a private commercial lot under construction at Vista Field found levels of PFAS (per-and polyfluoroalkyl substances) potentially above the limit set by Washington State Department of Ecology.
The Port has hired Landau Associates to develop a sampling methodology and take soil samples at Vista Field in mid-August to evaluate the site for PFAS.
The Port conducted a Phase 1 Environmental Assessment at Vista Field in 2014 that included extensive evaluation for all pesticides, insecticides, petroleum products and other chemicals listed by the Washington Department of Ecology as hazardous substances. The Assessment identified no conditions of concern. However, Ecology has since expanded its list of hazardous substances to include PFAS.
What are PFAS?
PFAS are a variety of synthetic chemicals used around the world since the 1950s. PFAS have been found in everyday consumer items like non-stick cookware, water- and stain-resistant products, grease-resistant food packaging and industrial uses such as firefighting foam and de-icing chemicals.
