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.

In what two ways can all sources of pollutants be classified?
Pollutants can be classified into point source pollution and nonpoint source pollution. Point solution originates from a single source. Nonpoint polluattion has no single source from where it can be traced.
Which term is used to describe pollution that comes from a single source?
Nonpoint source
What is the difference point source pollution and nonpoint source pollution?
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
Why is nonpoint source potentially more harmful than point source pollution?
The non-point source is potentially more harmful than the point source because it disrupts the water cycle.
What type of pollution comes from many different sources?
Nonpoint-source pollution
What is the difference between point and nonpoint sources of pollution?
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
Why does the government not do more to regulate nonpoint source pollution?
Nonpoint source pollution is difficult to regulate, because its source is difficult to track.
What is nonpoint-source pollution?
Nonpoint-source pollution comes from many different sources rather than just one.

What is non-point source 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.
Why is non point source pollution hard to control?
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.
