Program on the Environment

Per-and polyfluoroalkyl substances (PFAS) are man-made chemicals that do not degrade in the environment. They can remain in the human body for decades and cycle through the environment. Nicknamed “forever chemicals”, their persistence leads to bioaccumulation in wildlife and in human bodies. They are linked to increased risk of cancer, liver disease, and developmental issues. There is a significant lack of studies and state-wide policy on the interactions between PFAS and climate change. My project aims to compile existing climate change PFAS research, and use this information to better inform Washington State policy as the state rolls out new regulations and laws. Through an internship with UW’s Climate Impacts Group, I produced an academic report that included expert interviews with environmental scientists and policymakers, a comprehensive literature review, and policy recommendations. I collected data through interviews and compiled data provided by existing studies on the topic.
The studies indicate that warming temperatures, increased extreme storms, and changes in precipitation will increase the presence of PFAS in the environment due to higher rates of mobilization and changing chemistry.
My findings suggest that there is a need for more PFAS research and new cross-agency collaboration to create comprehensive policy on PFAS. More solutions include further financial incentives for companies to push out PFAS, and additional resources being allocated to PFAS removal technology.
