An example of non point source pollution would be the emission of lead from gasoline treated with tetraethyl lead. This source came from numerous points all across the country, from each and every car.. From the start of its use to it was passed out the average blood lead levels in Americans rose from essentially zero to 13.7 μg/dl in 1976. At this level the intelligence of children was impaired This is a vey serious impact.
An example of non-point source would be the emission of sulphur dioxide gas from smelters, power plant stacks and industrial processes. This caused acid rain which damage forests and soil over much of North America and destroyed the breeding areas of fish in countless lakes. Again a very serious impact.
From these examples it can be concluded that both types of problems are capable of causing serious impact. The major advantage of defined source emissions is that they can be controlled by discrete treatment systems (air pollution treatment) on a few well identified and identifiable sources rather than sweeping changes in gasoline formulas, engine design and a slow program of attrition to remove the millions of sources.
the difference is that a point source pollution comes from a specific site & the non-point source pollution comes from many sources rather than a single specific site. or point source pollution is pollution that comes from a known and specific location. Nonpoint source pollution is pollution that does not have a specific point of orign....................:-)Hisme John
Nonpoint-source pollution
Nonpoint source pollution is difficult to regulate, because its source is difficult to track.
Point source pollution is the term used to describe pollution that comes from a single identifiable source, such as a pipe or a smokestack.
Point sources of pollution come from a specific identifiable source, such as a factory or sewage treatment plant, while nonpoint sources come from diffuse sources like agricultural runoff or urban stormwater. Point sources are easier to regulate and control because they originate from a single location, while nonpoint sources are more challenging to manage due to their dispersed nature.

This is an example of nonpoint source pollution. Nonpoint source pollution refers to pollution that does not come from a single identifiable source but instead arises from multiple sources across a large area, making it difficult to pinpoint the exact origin of the pollution.
Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. 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.
Nonpoint source pollution can be more harmful than point source pollution because it comes from diffuse sources across a wide area, making it challenging to control and trace back to specific origins. This can lead to widespread contamination of water bodies and ecosystems. In contrast, point source pollution comes from identifiable and controllable sources, which can be easier to regulate and manage.
point-source of pollution is easy to because we can control it at the same site where the pollution source is originated. Nonpoint source pollution is difficult to regulate.
Sources of pollutants can be classified as point sources, where pollutants are discharged from specific locations such as industrial pipes; and nonpoint sources, where pollutants come from diffuse sources such as agriculture runoff or urban stormwater. Additionally, sources can also be categorized as natural sources, which originate from natural processes like volcanic eruptions, or anthropogenic sources, which result from human activities like burning fossil fuels.
