Sources of Pollution
Upstream Sources


Description:

Upstream sources of pollutants come into a waterbody from upstream.  When a bayou flows into a lake or lake into a bayou or a bayou into a bay the waterbody upstream is the upstream source. 

How does this land use cause Non-Point Source Pollution?

A pollutant in another waterbody from upstream will act the same way in a different waterbody downstream.  The only difference is that it comes from upstream.
