Salinity Shifts: A multi-faceted approach to understanding salinization in urban lakes

Monday, Sept. 15, 6:00 pM

In-person or virtual

Chloride pollution, primarily from winter salting, is a growing concern in Minnesota lakes. The RPBCWD Citizen Advisory Committee (CAC) invites the public to a guest presentation on Sept. 15th, 6-7 p.m., to learn more about a research project examining chloride pollution in Minnesota lakes.  The presentation will begin shortly after the CAC meeting is called to order.

About the presenter  

Hailey Sauer is a research scientist specializing in aquatic microbial ecology and environmental change. Her work bridges molecular biology, limnology, and biogeochemistry to understand how human-driven stressors alter freshwater ecosystems. She recently helped lead an LCCMR-funded project that uses high-frequency monitoring, paleolimnology, and modeling to identify salinity tipping points in urban lakes and assess how chloride pollution alters mixing, oxygen dynamics, and nutrient cycling.
