Project Summary: Per- and polyfluoroalkyl substances (PFAS), commonly referred to as "forever chemicals," are persistent organic pollutants that are widespread in the environment. Despite yard waste compost being widely recognized for its purity, the discovery of PFAS within it is unexpected and warrants thorough investigation to curtail the spread of PFAS through compost. This study is motivated by initial findings that suggest PFAS can migrate downwards through compost piles, driven by moisture. Therefore, our study aims to understand the dynamics of PFAS leaching from compost, considering both its chemical properties and the impact of freeze-thaw cycles. We anticipate uncovering the mechanisms behind PFAS leaching, informed by the specific characteristics of PFAS and compost, as well as freeze-thaw processes. This knowledge is crucial for developing strategies to mitigate PFAS pollution in the environment.
