Surface-irrigation of agricultural or domestic effluents onto soils has become the preferred treatment option in Australasia. However, transport and transformation of the carbon and nitrogen contained in effluents remains insufficiently understood. Leaching losses from effluent-irrigation have the potential to endanger the quality of the underlying groundwater. Management systems that minimize such losses have to be developed to ensure the long-term sustainability of land-based wastewater treatment systems.
