What do you think is the common cause of water pollution?


What are the classifications of water pollution?

Water Pollution“If wastes are put into the water, they cannot be seen; therefore, they must be gone. After all think of the billions and billions of gallons of water on this planet. There is no way we could ruin it.”

Water Pollution3 basic sources

PointDiffuse Background

Point Source Pollution

Direct introduction of contaminants into the water supply at an identifiable location

EX: Wastewater from factory being dumped into a stream through a discharge pipe

Diffuse source pollution

Aka non-point-source pollutionIntroduction of contaminants across a wide area

EX: Surface contamination from a farm or city that seeps into groundwater supply from runoff.

Diffuse source pollution

EX in nature: wild fire resulting from lightning might destroy vegetative cover of large land area. Rain or snowmelt result in erosion. Organic matter in water as well as dissolved salts and hydrocarbons.

Background Pollution

Ongoing natural processAs water moves, it generates forces that pick up particles and carry them along.

These materials dissolve and move into the water cycle

Background Pollution

Ongoing contamination from natural sources
