Nonpoint source pollution. NPS pollution is all water pollution that does not originate from regulated point sources. Nonpoint source pollution is a combination of pollutants from a large area rather than from specific identifiable sources such as discharge pipes. A whole lot comes from farm fields and city streets (known as “nonpoint” pollution). It tends to occur gradually and quietly. Types of regulated point sources include wastewater treatment facilities, municipal stormwater systems, and concentrated animal feeding operations. Non-point Source Pollution EPA 810-F-98-004 June 1998 . Nonpoint source pollution, or polluted runoff, is the greatest threat to coastal waters in the United States. Most nonpoint source pollution occurs as a result of runoff. Return to Nonpoint Source Pollution: A Brief History of Pollution This eerie photograph was taken at noon on Oct. 29, 1948 in Donora, PA as deadly smog enveloped the town. Now nonpoint source pollution — runoff from fields, livestock operations and cities — is the most troubling. A half-century ago, legislation began to reduce dumping by heavy industry into the Great Lakes. Initially, the danger escapes perception. 20 people were asphyxiated and more than 7,000 became seriously ill during this horrible event. NPS pollution occurs when rainfall flows off the land, roads, buildings, and other features of the landscape. Refers to any pollution carried by water that is not classified as a point source. Current: What You Can Do to Reduce or Stop Nonpoint Source Pollution State and local governments, volunteer groups, water quality professionals, and ordinary people are working together to clean up our lakes, rivers, streams, and wetlands. For our 50th anniversary, we commissioned author and journalist … Continued Sewage is another prime source of point source pollution, one we are still tackling. NPS pollution originates from various sources including run-off from the surface of pavements and lawns, secondhand sources like car exhaust and lawn fertilizer, and even boat hulls, which on a near daily basis, are in direct contact with water. Nonpoint source pollution is difficult to control because it comes from many different sources and locations. When rain or melted snow moves over and through the ground, the water absorbs and assimilates any pollutants it comes into contact with. One of the most significant sources of pollution is sediment … Polluted urban runoff. Nonpoint Source Pollution Zaki Uddin Ahmad 1, Maxim Sanin1, Qiyu Lian1, Mark Zappi2, Daniel Dianchen Gang1* ABSTRACT: This research article depicts a comprehensive review of scientific research advancement on nonpoint source pollution (NPS) in 2016. Nonpoint Source What is Nonpoint Source Pollution? Some pollutants come from the pipes of factories, sewage treatment plants or cities (known as “point source” pollution). The causes, impacts, and methods used to mitigate nonpoint source pollution were reviewed. Since 1990, New England Interstate Water Pollution Control Commission (NEIWPCC), in partnership with its member states, has been coordinating the Annual Nonpoint Source (NPS) Pollution Conference, a forum in the Northeast region for sharing information and improving communication on NPS pollution issues and projects. GRADE LEVEL: 4 – 7 BACKGROUND: This activity is designed to demonstrate to students what an average storm drain collects during a rainfall event and how the water from storm drains can impact the water quality and aquatic environments of local streams, rivers, and bays.
