Some chemical and biological aspects of water pollution in a portion of the upper Qu'Appelle River system
Warwick, William Frank
Water pollution has received increasing attention in recent years. With modern industrialization and increasing urbanization, the need for the preservation of our aquatic resources has become obvious. Shortages of water in some areas, whether due to climatic conditions or the destruction of the value of available waters by increasing pollutional loads, have made the conservation of our water resources mandatory. Prevention of pollution and its abatement in areas already adversely affected by its destructive forces are equally important in the preservation and augmentation of our natural water supplies.
