Central Michigan University alumna leads groundbreaking research on PFAS transport

A team of researchers has made significant strides in understanding the environmental impacts of per- and polyfluoroalkyl substances (PFAS) in groundwater and surface water systems. Among them is Eleanor McFarlan, a Central Michigan University (CMU) alumna, whose hands-on involvement in the study helped to develop new insights into the behavior of these persistent contaminants. The research, titled "Per- and Polyfluoroalkyl Substances (PFAS) Fate and Transport Across a Groundwater-Surface Water Interface," (available for free download through October 12^th here) sheds light on how PFAS move between groundwater and surface water environments, particularly in an area impacted by historical industrial waste.

Eleanor's journey at CMU played a pivotal role in enabling her to engage in meaningful, hands-on research experiences. Through her education and access to CMU’s resources, she was able to dive deep into the scientific exploration of environmental contaminants. Eleanor's direct involvement in fieldwork, data collection, and the modeling of PFAS behavior highlights how CMU’s commitment to practical, real-world research sets its students up for success.

The study focuses on a two-mile PFAS plume near Rockford, Michigan, a region historically impacted by PFAS contamination dating back to the 1960s. The team analyzed groundwater and surface water samples near fish-rearing ponds operated by the Michigan Department of Natural Resources, where PFAS have been detected. The findings suggest that groundwater contributes significantly to the water in the ponds, indicating a complex movement of contaminants across the groundwater-surface water interface.

Eleanor’s participation in field sampling and modeling was crucial in investigating how PFAS migrate between different water bodies and the factors that influence their behavior. Her work, alongside her fellow researchers, raised new questions about how these harmful substances are transported in natural environments. Eleanor’s passion for environmental research, fostered during her time at CMU, is a testament to the impact of hands-on learning and the value of dedicated mentorship in academic settings.

Congratulations to Eleanor and the entire research team for their contribution to the scientific community and for advancing our understanding of PFAS, an issue of growing concern across the world.
