Welcome to the GenX Exposure Study
The GenX Exposure Study is measuring GenX and other PFAS exposure in people living near the Cape Fear River Basin, North Carolina – the drinking water source for numerous North Carolina communities. We aim to understand current exposure and potential health effects to help answer questions for North Carolina residents.
We continue to work 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.
