NSW Diffuse Source Water Pollution Strategy

This strategy lays out a statewide approach for coordinated action and reporting to better manage diffuse sources of water pollution and improve water quality for all surface and groundwater.

Three priority diffuse source water pollutants have been identified across NSW – sediments, nutrients and pathogens – which can arise from a multitude of sources. The main focus of the strategy is the sources of these pollutants that are not already regulated. Examples, from private and public land, include some agricultural practices, unsealed roads, urban stormwater and specific urban activities. Sources that are already formally regulated, including sewerage systems, public forestry operations, waste services, intensive farming and some agricultural practices (for example pesticide use) are not covered.

A wide range of management approaches is needed to address the many causes of diffuse source water pollution. In most cases a combination of management actions will produce the best results and support landholders to make affordable changes.
