Marsh plants clean water in global purification effort
A three day University of Pennsylvania symposium highlighted marsh and pond based water treatment. Studies trace back to Dr Kaethe Seidel in Germany and Dr Joost de Joong in the Netherlands showing marsh systems remove phosphorus nitrates and bacteria while lowering energy use and costs. University of Wisconsin Oshkosh researchers led by Dr Frederic Spangler report similar gains with 7000 gallons daily sewage treated through a simulated marsh near Seymour.
