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.

| 1 June 2023 Hooray for Reid Milstead and his defense of his PhD in Environmental Chemistry and Technology! He studied the reactivity of dissolved organic matter during disinfection and photooxidation./p> |
|
| 6 May 2023 Expanding Your Horizons is back! It was so much fun to participate in this outreach event for middle school girls, female-identifying, and non-binary youth for the first time since the pandemic. A huge thanks to all the WSEL students and postdocs who made this happen. |
|
| 27 April 2023 Congrats to Sydney van Frost for her successful defense of her MS thesis on the fate of aquatic herbicides! Sydney was co-advised by Prof. Trina McMahon and in Civil & Environmental Engineering. We wish her the best as she starts her new job in Alaska. |
|
| 14 April 2023 Sam Bieber finished his MS in Chemistry and studied PFAS fate in tributaries of Lake Superior. We are excited for him to start his job at USGS! |
|
| 11 April 2023 Stephanie Berg’s massive study on dissolved organic matter photochemistry is out in Environmental Science & Technology. She studied the reactivity and composition of nearly 50 water samples from natural and engineered systems. |
|
| 27 December 2022 Our newest paper on the impact of environmental processes on the PFAS fingerprint of fluorotelomer AFFF is now out in Environmental Science & Technology. Check out coverage of this study by the Associated Press here. |
|
| 6 September 2022 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! |
|
| 20 July 2022 Amber White’s paper on the fate of 2,4-D in lakes is out in Environmental Science & Technology. This study synthesizes laboratory and field experiments to identify the dominant transformation mechanisms of 2,4-D. |
|
| 4 May 2022 Congrats to Emily Sellers for her successful defense of her MS thesis on PFAS in precipitation and municipal wastewater treatment facilities. Emily was co-advised by Dr. Martin Shafer at the Wisconsin State Laboratory of Hygiene. |
|
| 27 April 2022 Sydney Van Frost is the recipient of the 2022 Robert L. Johnson Memorial Research Grant and is the Midwest Aquatic Plant Management Society student representative. The award will support her research on herbicides used for invasive species control in lakes. Congrats, Sydney! |
|
| 10 February 2022 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. |

| 5 February 2022 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. |
