PFAS in Our Waters: Where They Come From and Where They Go 

PFAS—often called "forever chemicals"—are increasingly found in lakes, rivers, and streams across the country. These substances can enter surface waters from industrial sources, wastewater, landfills, and even rain. In this talk, we’ll explore where PFAS come from, how they move through the environment, and what we know about their presence in drinking water sources. We'll also discuss what’s being done to monitor and reduce their impact.  

Christoph Aeppli is a scientist at Bigelow Laboratory for Ocean Sciences, where he studies the environmental fate and transport of PFAS and other contaminants. His research focuses on how these chemicals move through and change in natural systems, including water, sediment, and organisms.  

All sessions are free to the public. Participants do not need to attend all sessions (each session stands alone, and participants can attend as many or as few as they choose). Light refreshments will be served.
