Disposal of liquid and dewatered sludge at storage sites and landfills is currently the most widely practiced method dealing with biosolids in Jordan. During 2004 an estimated 260,000 m3 of liquid sludge and 12,000 m3 of dewatered biosolids were generated in Jordan. Little information is available on the quality of biosolids in developing countries. The goal of this study was to assess the quality of biosolids generated after solar drying at two wastewater treatment plants in Jordan. The concentration of metals met requirements for exceptional quality biosolids based upon United States Environmental Protection Agency limits, however, based upon fecal coliform levels they would be consider Class B biosolids.
