Introduction How Rivers Run Stories Value Of A River What We Can Do
Quality of a River - Water Quality
Description (pg 1 of 2)

Water is vital to all life on Earth. The water in a stream sustains aquatic organisms such as fish and insects as well as organisms that live throughout the entire watershed. That includes humans. Entire cities may depend on the water in a single medium-sized river. Water is used for drinking, washing, watering and irrigation, and many commercial and industrial processes. The same water transports the effluent of wastewater treatment.

Because water is vital to life, it is accurate to say that poor water quality equals a poorer quality of life.

Even the human womb is an aquatic environment where the development and beginning of life is affected by water quality.
