Spray Fields, Living Filter

Penn State's Living Filter is a 50-year-old wastewater reuse system that spray-irrigates treated effluent from the University Park campus's sewage treatment plant on 600 acres of farm and forest. Unique in the eastern United States, the facility provides opportunities for researchers to conduct a wide range of water-quality experiments.
