Iowa Learning Farms Webinar: Understanding PFAS Levels and Sources in Iowa

February 9, 2022 @ 12:00 pm - 1:00 pm

Feb. 9 presentation by Dana W. Kolpin, research hydrologist with the U.S. Geological Survey will address the increasing levels of PFAS in Iowa’s water, and why we should be taking notice


Ames, Iowa – The Iowa Learning Farms (ILF) conservation webinar taking place Feb. 9 at noon CST will feature Dana W. Kolpin, research hydrologist, U.S. Geological Survey (USGS). Kolpin is co-lead of the USGS Food Resources Integrated Science Team and has published extensively on topics related to the fate, transport, and effects of environmental contaminants. He has recently worked on the first statewide spatiotemporal assessment of polyfluoroalkyl substances (PFAS), commonly referred to as ‘forever chemicals’, in Iowa streams.

In the webinar, “A Comprehensive Statewide Spatiotemporal Assessment of PFAS in an Agricultural Region of the U.S.,” Kolpin will discuss outcomes of the study which include the growth trends of PFAS levels in Iowa’s waterways and multiple potential agriculture-related release pathways for PFAS, such as biosolids and livestock manure, to enter the ecosystem. He will also speak about the mobility and persistence of PFAS that may enter water in both urban and rural areas.

“There is growing public concern about PFAS levels in water, but relatively little research has been conducted in agricultural regions such as Iowa to document levels and potential sources,” said Kolpin. “This study provides a critical baseline of PFAS data not previously available and documents the existence of PFAS even in rural basins. Unfortunately, the same properties that have made PFAS attractive for use in a wide variety of industrial and commercial applications also make them persistent and mobile, causing environmental exposures even in areas far removed from their initial use or manufacture.”

Participants in Iowa Learning Farms Conservation Webinars are encouraged to ask questions of the presenters. People from all backgrounds and areas of interest are encouraged to join.
