GenX Exposure Study

Welcome to the GenX Exposure Study

The purpose of this study is to assess current exposure to PFAS (per- and polyfluoroalkyl substances) and potential health effects in people living in the Cape Fear River Basin. We are measuring GenX and other PFAS chemicals in blood samples to help answer questions for North Carolina residents. People living in this region have been exposed to PFAS through contamination of drinking water sources, both the Cape Fear River and groundwater. We started this study in November 2017 and currently are funded to continue until 2025, so we hope to be able to answer some questions about these chemicals and their potential health effects.

As the principal investigator for this study, I have made it a top priority to share information about our results to our study participants. We are learning new things, navigating COVID-related closings, and other challenges, so we don’t have all the data and answers yet.  We will continue to share information as it becomes available.                   

On this website, you will find information about what questions we are asking, study results, and the ways we’re sharing results with the communities we work with. We continue to collaborate with other researchers to better understand PFAS and their effects. Science is a process and takes time, and we look forward to sharing our work with you.
