Strip Mines to Forests by Sewage Irrigation Study
At Pennsylvania State University researchers test spraying treated sewage sludge on strip mined spoil to grow grasses and tree seedlings. In 10 wooden boxes, eight treated with effluent show strong growth while two untreated boxes die. The project aims to restore vegetation over thousands of acres and could influence highway funding debates on use of sewage water for environmental restoration.
