CHATTANOOGA, Tenn. – After breaking the world record for speed swimming the Rhine River from the Swiss Alps to the North Sea in 2014, Dr. Andreas Fath, professor of medical and life sciences at Furtwangen University in Germany, is preparing for another endurance challenge on the Tennessee River.
Dubbed TenneSwim, Fath’s second “swim for science” will see him swim the entire waterway beginning July 27 at Ijams Nature Center through August. Fath will conduct daily analyses along his route to determine how water quality in the Tennessee River compares to the Rhine. This project will be the most extensive interdisciplinary water quality survey ever conducted of North America’s most biologically diverse river.
“Water pollution is not only a result of the industrial use of water but also a result of unconscious consumer behavior,” Fath says. “TenneSwim and the outcome will make people aware of their influence. Small changes in their behavior will have a big, positive effect on water quality.”
At 652 miles, the Tennessee River is 112 miles shorter than the Rhine, but its significantly slower current will pose an even greater challenge for Fath. If completed as planned, his swim will break another world record.
The Tennessee River and its many tributaries are home to more than 230 fishes, more than 100 freshwater mussels and more than 70 crayfishes. Its watershed also contains more than 150 turtle and more than 50 salamander species, including the giant Hellbender Salamander. Many communities rely on the Tennessee River for drinking water, including Knoxville, Chattanooga and Huntsville.
During TenneSwim, Fath and his team will sample for common water quality indicators such as temperature, nitrates and phosphates, as well as for pharmaceuticals, hormones, pesticides, bacteria, and heavy metals.
He will use a technique he pioneered to detect microplastics suspended in the water. These plastic fragments, less than 5 mm in size, are either manufactured at this size or created when larger plastic items break down into smaller pieces. Their small size enables microplastic to enter the food chain at the lowest levels. Microplastic has been found in the digestive tracts of both freshwater and marine animals.
TenneSwim is organized in partnership with the University of the South, the Tennessee Aquarium, The Nature Conservancy, the University of Georgia River Basin Center, Ijams Nature Center, the River Discovery Center of Paducah, Tennessee State Parks, and the Tennessee Valley Authority.
TenneSwim is presented with financial support from The Lyndhurst Foundation, Riverview Foundation, PerkinElmer, Sweetwater Brewing Company and a host of German sponsors.
