The prevention or control of stream pollution or the conservation of the quality of the water of streams has of late years become one of the primary objects of study in the United States. In the east a number of the states have been at work for several years and have arrived at some definite conclusion concerning the streams which flow through or border their states. A number of publications have been issued which clearly set forth the various problems of stream pollution and attempts have been made to explain a solution to the problem.
