point vs nonpoint source pollution quizlet

The U.S. Environmental Protection Agency (EPA) defines point source pollution as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack.”. Each pollutant causing a waterbody to be impaired or threatened is referred to as a waterbody/pollutant combination, and typically a TMDL is developed for each waterbody/pollutant combination. A non-point source usually refers to sources of pollution that are generated from a large area, rather than a single point. Letting these shrubs grow densely along the waterway prevents non-point source pollution and erosion. Nonpoint source pollution can come from many sources, like septic tanks, vehicles, farms, livestock ranches, and timber harvest areas. In contrast, point sources of pollution originate from a single point, such as a municipal or industrial discharge pipe. fairly easy to locate and monitor b) nonpoint sources i. broad, scattered, diffuse; can’t be traced to one site (large land areas, runoff, surface flow) ii. By 1987, however, it became clear that a great deal of pollution was coming from nonpoint sources. Hunting > Turkey Hunting. Its area varies in size, but can cover up to 6,000-7,000 square miles. Usually, if pollutants come from one source into that water body, such as factory waste disposal, it is called a point source pollution.. For example, during meat processing in a slaughterhouse, high volumes of water may be used making it a significant point source of pollution to local water bodies, ecosystems, and communities. The Gulf of Mexico dead zone is an area of hypoxic (link to USGS definition) (less than 2 ppm dissolved oxygen) waters at the mouth of the Mississippi River. NPS pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. “Polluted runoff is created by … 3. The key difference between point source and nonpoint source pollution is that the source of point source pollution can be traced back whereas nonpoint source pollution cannot be traced back to a single specific source. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. 5. Nutrients enter aquatic ecosystems via the air, surface water, or groundwater (Figure 1). This is another very important difference between the two types of pollution, and it is right at the heart of the other differences that are listed below. Nonpoint Source Pollution . Prior to 1987 most programs were directed at eliminating what is called point-source pollution: that is, discharges into water that are more or less easily tracked to their sources. Point and Nonpoint Source Pollution Examples Flashcards | Quizlet. It is different from point source pollution, which can be traced back to a single defined source. The differentiation between point and nonpoint sources of contamination is arbitrary to some extent and may depend in part on the scale at which a problem is considered. Runoff. 3. Natural Point-source pollution. The main difference between point source and nonpoint source pollution is that the point source pollution occurs through a specific, identifiable source whereas the nonpoint source pollution occurs through a combination of pollutants from a large area. http://www.theaudiopedia.com What is NONPOINT SOURCE POLLUTION? True or false: Non-point source pollution is a larger problem than point source pollution. Smokestacks of large factories and electric power plants that burn fossil fuels. Nonpoint Source. leaking underground storage tanks that contain chemicals or fuels such as gasoline. Pollution is the introduction of damaging or poisonous materials into the natural environment. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As opposed to point source pollution, nonpoint source pollution happens as a result of many different sources at the same time. Nutrient pollution released to freshwater and coastal areas comes from many diverse sources including agriculture, aquaculture, septic tanks, urban wastewater, urban stormwater runoff, industry, and fossil fuel combustion. However, due to anthropogenic activities and natural phenomena, the environment is contaminated with various substances. Point source is a specific and easily identifiable source of pollution, such as a factory or power plant. Nonpoint-source pollution can degrade a stream quickly by introducing organic and inorganic pollutants that bury streambeds, decrease oxygen and negatively affect aquatic life. Nonpoint source (NPS) pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. 4. Each individual plays a role in nonpoint source pollution, often without realizing it. Farmers who apply too much fertilizer, too much herbicide or too many other chemicals to their crops increase pollution in nearby streams. Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. A pollution permit or a treatment plant can't solve stormwater pollution, because stormwater runoff comes from small, individual sources in all parts of the watershed. Quizlet.com DA: 11 PA: 50 MOZ Rank: 67. Water Pollution ¾Obtaining clean, disease-free water for drinking is the major health problem facing most humans. Q. A gas leak from an underground tank.

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. Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage, or hydrological modification (rainfall and snowmelt) where tracing pollution back to a single source is difficult. https://importantindia.com/24048/point-source-and-nonpoint-source-pollution NPS pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. runoff pollution or have multiple benefits, such as high-efficiency street sweeping (which addresses aesthetics, road safety, and water quality). Point-Source vs Nonpoint-Source Pollution Flashcards Quizlet. Pollution that comes from MANY different places and is hard to identify its source. a common point, such as a nearby creek, stream, river or lake. Example: Effluent from a sewage treatment plant 2. Organic Matter 2. • Non-point source pollution cannot be traced to one specifi c source, and usually comes from many sources, such as car emissions. Where WLA is the sum of wasteload allocations (point sources), LA is the sum of load allocations (nonpoint sources and background) and MOS is the margin of safety. 3) sources of water pollution a) point sources i. specific sites of pollution discharge (pipes, ditches, sewers) ii. In addition to nonpoint source pollution, point source pollution (such as municipal waste water treatment plants, selenium ash pond discharge, industrial facilities, small package treatment plants, and urban and industrial storm-water systems) can degrade aquatic habitats. 4.3 Wastewater Treatment. Water pollution is the second most imperative environmental concern along with air pollution. Point source and nonpoint source pollution are two mechanisms of pollution. Every small watershed drains to a larger watershed that eventually flows to the ocean. The main difference between point source pollution and nonpoint source pollution is that point source pollution is easier to track to its source. Point source pollution and nonpoint source pollution are both potentially harmful to the environment. The largest amount of water pollution doesn't come from businesses, municipalities, or other regulated sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. Nonpoint source pollution occurs due to various unidentifiable causes. or text your registration number to 1-800-771-4692 and follow the prompts.
