2021: Issued the Final PFAS Chemical Action Plan recommendations. The plan incorporates feedback from stakeholders and the public, and will guide future actions to address PFAS in Washington.
2020: Issued PFAS Draft Chemical Action Plan recommendations. The plan incorporates new information related to PFAS activities in Washington and recommends actions to reduce the impacts of PFAS in our state.
2019: Issued preliminary PFAS Chemical Action Plan recommendations.
2018: In partnership with the Department of Health, published the Interim PFAS Chemical Action Plan. The plan included protective actions from two new laws related to the use of PFAS-containing firefighting foam and an analysis of food packaging:
2017: Updated the Children’s Safe Products Reporting Rule adding PFOA to the list of chemicals of high concern to children. When originally adopted in 2011, the list of chemicals of high concern to children included PFOS.
2016: Conducted a follow-up study on PFAS in rivers and lakes.
2008: Conducted a study to assess PFAS in rivers and lakes in Washington.
2006: Adopted Persistent, Bioaccumulative, and Toxics Rule listing PFOS and its salts as persistent, bioaccumulative, and toxic chemicals.
Most PFAS research has been done on two specific compounds: perfluorooctane sulfonate (PFOS) and a related compound, perfluorooctanoic acid (PFOA). The toxicity of other PFAS compounds varies. Studies in animals show that exposure to some PFAS can affect liver function, reproductive hormones, development of offspring, and mortality.
Although nearly all of us are exposed to PFAS, their toxicity in humans is not completely understood. Experts investigating the effects on people have found probable links to immune system toxicity, high cholesterol, reproductive and developmental issues, endocrine system disruption, ulcerative colitis, thyroid issues, certain cancers, and pregnancy-induced hypertension.
