Madison from the air

The Aquatic Chemistry group at UW-Madison focuses on processes that impact water quality. We study the fate of polar organic contaminants, such as pesticides and PFAS, in natural and engineered aquatic systems. We also study processes that transform organic chemicals, including the role of dissolved organic matter in those systems. By studying these fundamental reaction mechanisms, our group aims to develop models and real-world applications that can be used to improve water quality.

It is trophy time! Emily Sellers and Amber White received their research-inspired, custom trophies in celebration of their graduations. Best lab tradition ever?

23 August 2022

Amber White successfully defended her PhD on the fate of aquatic herbicides in lakes! Amber was co-advised by Trina McMahon and mastered both environmental chemistry and biology in her graduate studies. We are excited to see what she does next!

Dr. Sarah Balgooyen’s study on per- and polyfluoroalkyl substances (PFAS) in tributaries of Green Bay is now out in ACS ES&T Water. In this Wisconsin Sea Grant-funded study, we found that large tributaries contribute the most PFAS to the bay even if their PFAS concentrations are relatively low. We also found that PFAS can be released from tributary sediments.

It was so fun to be back at Frozen Assets sharing our research with the public at Science on Ice. Poster sessions on ice are the best poster sessions.
