The second biggest form of pollution in the river is fertilizer runoff. This is measured by nitrogen parts per million found in collected samples regularly. The nitrogen from the fertilizers do the same thing to algae that it does to land plants. They grow like crazy. The affect is two-fold:
1: The water becomes murkier from the algae growing in it. This inhibits sunlight's path to the bottom of the river, and destroys naturally occurring plantlife there, the bottom of the ecosystem.
2: The algae eventually dies and rots in the water, and as it decomposes, sucks oxygen out of the river, killing fish, especially large ones, and applies pressure to other wildlife dependent on the river.
The third largest source of pollution is sedimentation. Typically caused by construction and urbanization, loose dirt washes away with rainwater clouding the river and eventually settling to the bottom at a faster rate than the river carries it away naturally. The clarity effects are the same as the algae effect, and the depth changes affect the flow and temperature of the river, which is stressful to the ecosystem.
