How does littering affect our drinking water? This video from NCTCOG ED describes with great clarity how our fresh water is polluted, how it is treated, and what we can do to help.
Fertilizers are used in agriculture to provide one or more of the chemical elements necessary for plant development. Excess amounts of fertilizer, containing large amounts of nitrogen and phosphorous, enter water sources through surface runoff and leaching. This increased amounts of nitrogen and phosphorous have negative impacts on water quality and human health. Utah State University and The University of Vermont explain how fertilizers harm our water sources, and how proper fertilizer management can help cut down pollution.

What are the health risks of drinking water with high nitrogen levels?
The National Ocean Service explains turbidity currents as a rapid, downhill flow of water caused by increased density due to high amounts of sediment.
