"TenneSwim will make people aware of their influence on the river and how small changes in behavior will have a big, positive effect on water quality." - Dr. Andreas Fath
Knoxville, TN (PRWEB) July 14, 2017
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 from late July 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.
TenneSwim begins July 27 at Ijams Nature Center in Knoxville and 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.
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.
In 2014, Fath and his team of scientists analyzed the Rhine for more than 600 substances and found that concentrations of persistent pollutants increased as they moved downstream. “We found the great ‘blockbusters’ in the Rhine,” Fath says, “from artificial sweeteners to residues of dishwasher tabs.” This means many substances we consume or use in our everyday lives survive wastewater treatment and end up in waterways.
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.
Fath already has one prediction of what he’ll find in the American river.
“The use of lawn fertilizers is much more common in the United States than in Germany,” Fath explains. “That is why I expect significantly higher concentrations of phosphate in the Tennessee River.”
During TenneSwim, Fath 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.
In 2014, Fath and his team found large quantities of microplastics in the Rhine. Fath estimates that, every year, the Rhine carries eight tons of plastic all the way to the North Sea – on its surface alone. “Literally, this is only the tip of the iceberg,” he says. “Actual microplastics pollution in the Rhine is most likely many times higher.”
This leaves many wondering what levels of contaminants and microplastics Fath will discover in the Tennessee River.
TenneSwim is presented with financial support from The Lyndhurst Foundation, Riverview Foundation, PerkinElmer, Sweetwater Brewing Company and a host of German sponsors.
How you can help:
Water covers most of the earth’s surface, but only about 2.5 percent of it is fresh water. Of that, less than 1 percent is easily accessible for human use. That makes every drop — and every individual action that could impact a waterway — critically important. Here are five ways you can safeguard the rivers, lakes and streams near you:
- Don’t Flush Your Meds — Any pharmaceuticals you flush down the toilet or pour down the sink inevitably end up in a body of water. As part of its National Take-Back Initiative, the U.S. Drug Enforcement Administration has authorized thousands of collectors who can safely dispose of unused medication for you. Find a collector near you by using this search tool or call 1-800-882-9539.
- Skip the straw — Plastic is the most prevalent type of debris in aquatic environments, and single-use plastics, such as drinking straws, are a major source of this pollution. Over time, these items break down but don’t fully biodegrade, creating fragments (microplastics) that can be consumed by animals, impacting their ability to feed as well as contaminating the seafood people enjoy. Instead of a plastic straw, use an alternative, reusable sipping device made from paper, metal, glass or even bamboo.
- Fertilize with Care — Using too much fertilizer can affect your plants’ ability to absorb water and can contaminate nearby streams when the excess is carried away by stormwater run-off. To prevent this, follow the label instructions carefully to mix the fertilizer accurately and only use it during the appropriate time of year.
- Don’t Go Down the Drain — Storm drains are like superhighways that transport chemicals, unfiltered and untreated, into local waterways. Do a web search to find local hazardous waste disposal sites near you rather than risk a fine or damage to a nearby stream.
- Jump In! — Stricter government regulations have made many waterways safe for human recreation, but that wasn’t always the case. You can now fish, swim, paddle or otherwise enjoy many of the rivers, lakes and streams near you because of the clean water regulations of the past 45 years. By making use of these waterways, you’ll show legislators that communities value the cleaner water these laws made possible.
- The TenneSwim begins at Ijams Nature Center in Knoxville, Thursday, July 27 at 10 a.m. The public is invited, though parking is limited. Reporters interested in attending this event should RSVP to Cindy Hassil at Ijams Nature Center to ensure adequate parking and transportation arrangements have been made.
- Andreas Fath arrives in Chattanooga, Friday, August 4 around 6:30 p.m. He will speak at the Tennessee Aquarium’s River Journey auditorium on Thursday, August 3rd. This will be a ticketed event. For more details on tickets, visit the Aquarium's website.
- The TenneSwim culminates in Paducah, KY at the confluence of the Ohio and Tennessee Rivers which the River Discovery Center overlooks. At press time, it was expected that Fath will arrive in Paducah around Aug. 26. Follow http://www.tenneswim.org for the latest details on the ending celebration event.
