One of the most significant sources of pollution is sediment … Some pollutants come from the pipes of factories, sewage treatment plants or cities (known as “point source” pollution). Now nonpoint source pollution — runoff from fields, livestock operations and cities — is the most troubling. Nonpoint source pollution, or polluted runoff, is the greatest threat to coastal waters in the United States. 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. 20 people were asphyxiated and more than 7,000 became seriously ill during this horrible event. 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. Non-point Source Pollution EPA 810-F-98-004 June 1998 . 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 a combination of pollutants from a large area rather than from specific identifiable sources such as discharge pipes. Most nonpoint source pollution occurs as a result of runoff. The causes, impacts, and methods used to mitigate nonpoint source pollution were reviewed. Types of regulated point sources include wastewater treatment facilities, municipal stormwater systems, and concentrated animal feeding operations. Nonpoint Source What is Nonpoint Source Pollution? Sewage is another prime source of point source pollution, one we are still tackling. Polluted urban 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. Nonpoint source pollution is difficult to control because it comes from many different sources and locations.

NPS pollution occurs when rainfall flows off the land, roads, buildings, and other features of the landscape. Runoff is generally associated with nonpoint source pollution, as water is emptied into streams or rivers after accumulating contaminants from sources like gardens, parking lots or construction sites.
