FROM STORMWATER TO DRINKING WATER

February 2, 2016

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.

How does stormwater runoff pollute the water supply?

What is nonpoint source pollution?

FERTILIZERS AND WATER QUALITY

January 5, 2016

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.
