What is point pollution?

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” http://www.eoearth.org/view/article/155279/

Onondaga Lake Superfund Sites

There are around 165,000 pounds of mercury and other contaminants to the lake. Disposed 80 million gallons of acid, tar-like wastes 400 feet from the lake. Extensive site investigation nearly complete. GM capped an on-site landfill and reduce pollution threats.

What is the difference between Non-point and Point Pollution?

Point Pollution- Is a chemical or other pollutant that flows into the environment from one specific point such as drain, smoke stack, or pipe. But Non Point Pollution is a chemical or other pollutant that flows into the environment as it is picked up runoff or other indirect sources such as fertilizers, pesticides, and waste.
