We have two new papers out in Environmental Science & Technology on PFAS partitioning in (1) naturally forming foams and the surface microlayer and (2) freshwater ice. Both papers were led by postdoc Summer Sherman-Bertinetti. For more on the foam study, please see the UW-News video and press release.

Congratulations to Eddie Kostelnik (left) and Lauryn Angell (right) on successfully defending their master’s theses in Environmental Chemistry and Technology. Eddie studied the photochemistry of dissolved organic matter and Lauryn studied the fate of lampricides in tributaries of the Great Lakes.

Congrats to Jenna Swenson for her shiny new first-author paper in Environmental Science & Technology. She investigated the combined impacts of cations and dissolved organic matter on manganese oxide reactivity in collaboration with Matt Ginder-Vogel. We are super proud of her work on this incredibly complex system.

Our latest study on aquatic herbicides is now out in Environmental Science: Processes and Impacts. This was a team effort, with work performed by two master’s students (Sydney Van Frost and Angela Magness), a PhD student (Amber White), and a UW-Madison undergraduate (Josie Jauquet). They showed that laboratory measurements underestimate the persistence of the herbicide fluridone in lakes.

Christy was named the interim director of the Aquatic Sciences Center, which is home to the Wisconsin Sea Grant College Program and the University of Wisconsin Water Resources Institute (WRI). Both programs support multidisciplinary research, education and outreach for the protection and sustainable use of Wisconsin’s water resources.

Our latest paper on quantifying photochemically produced reactive intermediates is out in Environmental Science: Processes and Impacts. This study was a team effort between two UW-Madison PhD students (Reid & Steph) and an amazing group of undergraduate researchers in the lab of Kris Wammer at the University of St. Thomas.

Our study on the fate of the aquatic herbicide florpyrauxifen-benzyl (FPB) is published in Environmental Science & Technology. This study combines laboratory and field studies to investigate the role of multiple simultaneous processes in FBP fate.

Reid’s paper on dissolved organic matter photooxidation is now out in Environmental Science & Technology. He used high-resolution mass spectrometry to link dissolved organic matter composition with its photoreactivity.

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.

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.

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.
