Find out how pollutants enter water environments. Pollutants enter water environments from two main types of sources. A point source is a single, identifiable source of pollution, such as a pipe or a drain. Industrial wastes are commonly discharged to rivers and the sea in this way. EPA regulates high-risk point source waste discharges through the
works approval and licensing system, and associated compliance and enforcement activities. EPA’s regulation of point source waste discharges has been important in improving the quality of Victoria’s water environments. No longer do we have raw sewage and abattoir waste continually flowing in our
rivers as we did in the 1970s. While effort is still needed to maintain and further improve these environments, some of the major threats to the health of Victoria’s water quality are now from non-point sources. Non-point sources of pollution are often termed ‘diffuse’ pollution. They refer to inputs and impacts which occur over a wide area and are not easily attributed to a single source. They are often associated with particular land uses, as opposed to
individual point source discharges. In our urban areas, rainfall run-off as stormwater is one of the major non-point sources of pollution impacting the water quality of our waterways and bays. Stormwater from street surfaces is often contaminated with car oil, dust, animal faeces, and soil and sediment run-off from construction sites, and in
industrial areas often contains more toxicants and chemicals. In some outer-urban and urban fringe areas, a reticulated sewerage system is not available so sewage is discharged to onsite wastewater systems and septic tanks. Seepage and surface run-off of septic tank effluents may also be forms of non-point source pollution of streams in
these areas. In farming areas non-point sources of pollution include pesticides, fertilisers, animal manure and soil washed into streams in rainfall run-off. Where stock are given access to stream banks they may foul the water and accelerate erosion. Forestry operations may contribute to non-point source pollution of streams by increasing soil erosion and sediment run-off. Managing non-point sources of water pollutionNon-point source pollution is often more difficult to control than point source pollution. In urban areas the provision of reticulated sewerage systems and adequate street cleaning are important measures, while in farming and forestry areas, soil conservation practices and the controlled application of pesticides and fertilisers are necessary if pollution of waterways is to be avoided. While EPA does not directly license or approve many of these non-point source activities through regulation, we often work with partners from government, industry and community across different aspects of our operating model to help tackle these issues.

Which one of the following is an example of a nonNonpoint pollution sources are broad, diffuse areas, rather than points, from which pollutants enter bodies of water. Examples include runoff of chemicals and sediments from cropland, livestock feedlots, clear-cut forests, urban streets, parking lots, lawns, and golf courses.
Which of the following is a nonUrban and Suburban lands cause water pollution by the field run offs and thus do not originate from a single point. Hence, they are non-point sources of water pollution.
