The Types of water Pollution
polution that comes from one specific source is point-source pollution. for example, wastewater that is released from a factory is point-source. this type is usually much easier to controll and regulate. nonpoint-source pollution is pollution that comes from many sources. this type of pollution is much harder to control because it does not come from a single source. examples of nonpoint-source pollution include agricultural and urban runoff, land clearing, construction, and forestry.
