Forever Chemicals in Farm Ponds: Dr. Ty Hoskins Studies PFAS in Fish Populations
Season 3, Episode 5
Show notes
In this episode of the Lake Doctor podcast, Suzie Light and Dr. Nate Bosch talk with Dr. Ty Hoskins, Research Assistant Professor at Purdue University’s Department of Forestry and Natural Resources. Ty breaks down PFAS—per- and polyfluoroalkyl substances, better known as “forever chemicals”—explaining why their ultra-strong carbon-fluorine bonds make them so useful in everyday products and so persistent once they reach the environment.
He shares his research on PFAS in largemouth bass living in Indiana farm ponds near fields that receive agricultural biosolids. The conversation covers how these chemicals move from wastewater sludge into soils and nearby waters, why ponds are both understudied and highly relevant, and how bioaccumulation and biomagnification can concentrate PFAS in the fish people catch and eat. Ty also clarifies the science in plain language, from surfactant properties to indicator species, giving listeners a clearer picture of a complex and important water-quality issue.

This conversation shines a light on the hidden world beneath the surface, revealing how small and unassuming species play an outsized role in the health of our aquatic ecosystems. Brant also discusses the ongoing challenges non-game species face, like the harvesting of shells for jewelry and the complexity of mussel reproduction. He offers practical steps we can take going forward to support conservation efforts. Develop a deeper level of appreciation for Indiana’s non-game aquatic life.
Brant Fisher, originally from western Pennsylvania is a nongame aquatic biologist with the Indiana DNR. Brant monitors species that are not typically fished for sport like mussels, darters, crayfish, and freshwater jellyfish. When doing mussel surveys, these biologists will often crawl through rivers and streams while scanning the bottom with their hands. Brant has worked at educational events in the past where he teaches about aquatic ecosystems. Brant has also collaborated with Purdue and other environmental nonprofits to support mussel restoration and research projects.
