Pollution and Water Stewardship8 E 1.4

Pollution types- point source

Point source pollution = source of pollution is known and identifiable.

Real life examples= toxic effluents from a factory, agricultural run-off. Effluents= chemicals or fluid that flows out

Pollution types- nonpoint sourceNonpoint source pollution = source

of pollution is too widespread to identify or blame

Real life examples= urban run-off from roads and parking lots, neighborhood run-off from storm drains, sewage leaks such as pig waste or pesticides, and overfishing from fisheries.

Ways to correct- nature

Water is recycled through the water cycle.

Water is filtered through percolation.

This method is mostly effective but time

consuming.

Ways to correct- LegislationThere are many laws that impact

water quality on federal, state and municipal books.

Two most important-Clean Water Act (1972)

and Safe Drinking Act (1974)
