Wetlands are nature's way of filtering water. Most sewage treatment facilities remove about 90% o organic waste and less than 50% o phosphates and nitrates, returning the polluted water back into the environment. This video shows how some cities are using unique wetland technology to treat their wastewater with surprising results. You'll also see how high school students are building a wetlands model in hopes of cleaning up Chattanooga Creek, a superfund site.
