FIGURE 13.43 Käthe Seidel, a researcher at the Max Plank Hydrobiological Institute—shown here explaining aspects of her work to colleagues—pioneered the use of constructed wetlands to treat a wide range of wastes. She was inspired by her doctoral studies of the common bulrush Schoenoplectus lacustris, which she observed growing in conditions that, prior to her research, were thought to be impossible for aquatic plants.
