The concept of environmental auditing of point source pollution has been adapted to nonpoint source pollution in rural lands. Geographic Information Systems (GIS) and other information technologies provide an effective environmental management tool for characterising nonpoint source (NPS) pollution in a regional context and thereby can assist the environmental auditing process. Nonpoint source pollution problems of rural watersheds in Australia, particularly those in the state of New South Wales, and the role of the state's environment protection agency are outlined. A case study that applies an auditing methodology using GIS in a study area within the Lachlan River catchment is presented. The suitability of the approach for land condition evaluation and the review of land use controls for nonpoint source pollution is discussed.
