Caroline Alukkal - PhD Defense Announcement Understanding Treatment Process Effects on PFAS in Municipal Wastewater Solids Stream Major Professor: Dr. Linda Lee Monday, July 8th at 1:00 PM LILY 2425 Ecological Sciences and Engineering Interdisciplinary Graduate Program Division of Environmental and Ecological Engineering Per- and polyfluoroalkyl substances (PFAS) are synthetic compounds known for their diverse applications, from everyday products like food wrappers and raincoats to life-saving uses in firefighting foams. However, their pervasive presence in consumer goods leads to their eventual disposal into sewage systems. Recently, PFAS have garnered significant attention due to mounting environmental and health concerns. Unfortunately, conventional wastewater treatment methods struggle to completely eliminate or degrade PFAS, resulting in their accumulation in effluent and biosolids, perpetuating their environmental cycle. Currently, there is limited understanding of how PFAS behave within the waste stream. To address this gap, there is an urgent need of an optimized method for evaluating PFAS in complicated solid matrices such as biosolids. A new method developed and optimized through this research was used for extracting and analyzing PFAS and the results were utilized to examine how two key wastewater treatment processes affect the transformation of PFAS. This research aims to provide utilities and regulatory bodies with crucial data for informed decision-making regarding treatment processes. Ultimately, this knowledge will facilitate the effective management of PFAS in biosolids, promoting their safe and beneficial utilization. Everyone is welcome! Attached is the defense announcement.
