History of pollution. Cities of ancient times were often noxious places, fouled by human wastes and debris.

Where does non point source pollution come from?

Nonpoint source pollution can come from many sources, like septic tanks, vehicles, farms, livestock ranches, and timber harvest areas. Pollution that comes from a single source, like an oil or chemical spill, is known as point source pollution. Point source pollution events often have large impacts, but fortunately, they occur less often.
