PFAS Contamination

The effects of PFAS on drinking water continue to be researched.




LA CROSSE (WXOW), Wis. – Continued research is being done on the effects of PFASs in drinking water.

With those studies, <a href="https://www.epa.gov/pfas/key-epa-actions-address-pfas#:~:text=In%20April%202024%2C%20EPA%20issued,of%20thousands%20of%20serious%20illnesses." The federal government is preparing to enforce new limits on the amount of PFAS found in our drinking water.

The first studies on PFAS date back to the 1990s. There are over 15,000 different types of PFAS.

Tisha King Heiden, a UW-La Crosse student, and her colleagues are studying the effects of PFAS on the early development of fish.


The research aims to fill a knowledge gap by determining how much PFAS there is in fish eggs and how it affects the survival of these embryos.

King-Heiden stated that “our research informs agencies like DNR etc. who set limits for the contaminants in our environment to keep us safe.” We need to support this information with data. We can refine our knowledge by generating more data.


This study could answer questions like how much PFAS can be injected into a human embryo before harm occurs. The study could also distinguish between wild fish populations that are exposed to PFAS chemicals.


Anika Oplanic, a student who assists in the research. She stated that the research was important, but it was more about the people who were affected by PFAS chemicals.

It is important to make sure that the public understands this issue. “We can talk all day about the scientific jargon and go to conferences to talk with other professionals. But at the end of it all, we find that this is a public-health issue,” Oplanic explained. “And that’s exactly what the agencies have explained.”

King-Heiden was awarded a Wisconsin Sea Grant of $260,000 by the National Oceanic and Atmospheric Administration.
