When it comes to aquatic plant management, words matter

Play Episode Listen Later Feb 7, 2025 4:30


People searching online for control options related to unwanted plants that grow in lakes and rivers use many different terms. Some call them “lake weeds,” other call them “freshwater seaweed,” still others “cabbage.” Rarely do people search with the same terms that natural resource managers and scientists use, such as the plants' Latin names or the more formal, “submerged aquatic vegetation.”These are findings of a study on internet keyword search terms conducted by University of Wisconsin-Madison researchers that was recently published in the “Journal of Aquatic Plant Management.”Wisconsin Sea Grant Aquatic Invasive Species Outreach Specialist Tim Cambell explains that how people search for information about aquatic plants is critical for guiding professionals on best practices for educational programming and outreach. Such education could also steer people away from the ineffective and potentially harmful use of herbicides in lakes and toward more ecologically sound solutions.

Oil spills trigger natural pollutants in groundwater

We all know that oil spills pollute water. But what might be news is that they can also trigger the release of natural pollutants when the spills reach groundwater. This pollution domino effect is the topic of a current Water Resources Institute-funded study by Matt Ginder-Vogel at the University of Wisconsin–Madison. He's working with investigators Beth Parker from the University of Guelph and Jessica Meyer from the University of Iowa.The team found the perfect real-world location for their two-year experiment in Cottage Grove, Wisconsin, which is about 12 miles east of Madison. This is the site of multiple past organic hydrocarbon (or oil) spills from an organic solvent recycling plant.

On a sunny morning in mid-June 2024, the Phoenix, University of Wisconsin-Green Bay's research vessel, headed out onto the bay. Aboard were Sea Grant researchers Emily Tyner and Bill Sallak and a small mound of recording equipment. It was piloted by Chris Houghton, assistant professor and fish ecologist, who was assisted by first mate, undergraduate student Jacob Hoffman.The bay tour was only supposed to last for three hours but like in the theme song for the “Gilligan's Island” television show, a mishap was involved.Tyner and Sallak's project is associated with the development of a national estuarine research reserve on the bay. It will be the third reserve on the Great Lakes after Old Woman Creek in Ohio on Lake Erie and the Lake Superior Reserve in Superior, Wisconsin.They planned to record natural noises from the bay, particularly bird sounds. Their target: the Cat Island Chain, restored barrier islands in the bay that have created new habitat for migrating and nesting shorebirds.Tyner and Sallak plan to make the sounds of the bay available in a presentation and online. They hope it will connect the community to the bay, which has been shunned in the past due to environmental issues.

Lake and River Foams Study Reveals High PFAS Levels

In a new study, natural foams and water surface microlayers of 43 Wisconsin rivers and lakes were found to contain 36 compounds in a group of chemicals known as PFAS. While PFAS were detected in both the foam and the water surface, it's the foams that the researcher said were orders of magnitude higher in PFAS concentration compared to water, and they urge people and their pets to avoid them. The study also revealed that foams, generally off-white and found along shorelines on windy days, are not an indicator of elevated contamination levels in the entire water body.Leading the project is Christy Remucal with the University of Wisconsin-Madison Department of Civil and Environmental Engineering and interim director of the University of Wisconsin Aquatic Sciences Center.

A new report published by the University of Wisconsin-Madison found that Wisconsin's rural residents perceived significant risks to water quality from pesticides, PFAS (which are per- and poly-fluoroalkyl substances) and excess nutrients. They also ranked water as very or extremely important for supporting wildlife and for hunting and fishing, in addition to home uses such as drinking and cleaning.These findings regarding groundwater and surface water are based on a study by UW-Madison professors, including Michael Cardiff via a research project funded by the University of Wisconsin Water Resources Institute. The report, entitled, “Rural Resident Perceptions of Wisconsin's Waters” is available for free download from the Water Resources Institute website.
