Nature pumps it's own oil from the ground into many areas. Indians used this goo for different purposes.
When the single source of pollution can be identified, it's called
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.
Nonpoint source
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
Point-source pollution
When the single source of pollution can be identified, it's called
Water pollution, it can cause serious problems like industrial wastes can.
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.

Nonpoint source
The largest source of human-caused air pollution is the burning of fossil fuels. 90% of air pollution is from power plants and automobiles.

Sources that have water, mainly piped water from a single point.
A single person or animal could definitely be a cause of point-source pollution. People release poisons into the environment every day.
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.
