The United States Environmental Protection Agency (EPA) defines point source pollution as any contaminant that enters the environment from an easily identified and confined place. Examples include smokestacks, discharge pipes, and drainage ditches. Factories and power plants can be a source of point-source pollution, affecting both air and water.
What is point pollution vs non point 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. Point source and nonpoint source pollution are two mechanisms of pollution. Discharge pipes from factories, sewage treatment plants, and ...

Point source pollution has a known and specific location. Nonpoint source pollution does not have a specific point of origin.
What is non-point source water pollution?
Nonpoint source pollution occurs when runoff from rain and snowmelt carries pollutants into waterways such as rivers, streams, lakes, wetlands, and even groundwater.
Is sewage a nonpoint-source pollution?
Point Source Pollution The main point source dischargers are factories and sewage treatment plants, which release treated wastewater.
What does nonpoint mean?
Definition of nonpoint : being a source of pollution (such as runoff from farmland) that is not confined to a single point also : being pollution or a pollutant that does not arise from a single identifiable source.
Which of the following is nonpoint sources of water pollution?
Nonpoint source pollution can include: Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. Oil, grease and toxic chemicals from urban runoff and energy production. Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks.
What is nonpoint source pollution?from 19january2017snapshot.epa.gov
Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. Nonpoint source (NPS) pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters.
How does nonpoint source pollution affect the value of waterfront property?from oceanservice.noaa.gov
Excess nonpoint source pollution impacts the overall quality of life , and subsequently can drive property values down. If nonpoint source pollution continues to plague the waters surrounding coastal communities, their economies and social conditions may rapidly deteriorate.
How does nonpoint source pollution affect the economy?from oceanservice.noaa.gov
Nonpoint source pollution not only affects ecosystems; it can also have harmful effects on the economy. U.S. Coastal and marine waters support millions of jobs, generate billions in goods and services through activities like shipping, boating, and tourism, and contribute billions to the U.S. economy through recreational fishing alone. If pollution leads to mass die-offs of fish and dirty-looking water, deep financial losses often result.
What is a nonpoint source?from 19january2017snapshot.epa.gov
The term "nonpoint source" is defined to mean any source of water pollution that does not meet the legal definition of "point source" in section 502 (14) of the Clean Water Act. That definition states:

Is parking lot runoff harmful?from oceanservice.noaa.gov
The water flows downstream into a larger stream, and then to a lake, river, or ocean. The pollutants in this runoff can be quite harmful, and their sources numerous. We usually can’t point to one discreet location of nonpoint source pollution like we can with a discharge pipe from a factory.
What are some examples of pollution?
Examples include smokestacks, discharge pipes, and drainage ditches. Factories and power plants can be a source of point-source pollution, affecting both air and water. Smokestacks may spew carbon monoxide, heavy metal, sulfur dioxide, nitrogen dioxide, or “particulate matter” (small particles) into the air.

Regulatory agencies charged with protecting the environment identify two main categories of pollution: point-source and nonpoint-source pollution.
What is the term for a natural substance that kills organisms that threaten agriculture or are undesirable?
natural or manufactured substance used to kill organisms that threaten agriculture or are undesirable. Pesticides can be fungicides (which kill harmful fungi), insecticides (which kill harmful insects), herbicides (which kill harmful plants), or rodenticides (which kill harmful rodents.)
Why is acid rain considered nonpoint source pollution?
Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.
How does runoff affect the environment?
In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.
Why is runoff a problem?
Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.

Other common point sources of water pollution are farms and oil refineries. Jet engines are often cited as point sources of air pollution, while light pollution can be attributed ...
What is nonpoint pollution?
As opposed to point source pollution, nonpoint source pollution happens as a result of many different sources at the same time. It is much harder to identify and usually covers a much larger area. There are numerous types of nonpoint sources, like line, area, or volume sources, to name a few.
What are some examples of industrial sources?
Industrial sources can vary immensely, but one example can be the emissions from chimneys in factories and are often the cause of air pollution. One thing to mention is that, while being easily pinpointed, point sources usually don’t have clearly defined geometrical dimensions.
What is a point source?
The name point source is derived from algebra, meaning something that can be estimated as a mathematical point to make analysis less complicated. Point sources of pollution are the same as point sources found in other scientific disciplines such as chemistry, physics, or engineering.
How can we prevent water pollution?
Another method of preventing water pollution are autonomous watershed preservation efforts. Pollution prevention is, however, most efficiently executed at local, state, and federal levels. Every citizen can also help by actively trying to be informed about pollution and trying to prevent it, even on a small scale.
Is pollution a point source?
Point source pollution is easily identifiable, it comes from a single source, while nonpoint source pollution can come from multiple places at the same time. The United States Environmental Protection Agency (EPA) offers a definition of point source pollution that describes it as any pollutant that infiltrates the environment from a place that can be pinpointed without difficulty. State and federal departments supervise these point sources.
