Causes

Various contaminants that lead to degradation of the water quality include Pathogens, Chemicals and other sensory and physical changes. Most of these contaminants are either Oxygen depleting, where they deplete the water body of requisite oxygen for survival of aquatic species, some of them are toxic as they produce some toxic substances that can prove fatal and harmful for life to survive, also many of them are capable of blocking the sun-light which in turn restricts the normal cycles for survival of life. 

Pathogens like Viruses, parasitic worms’ results from ill-treated sewage discharge. Chemicals resulting in water pollution are classified as Organic and Inorganic. Organic chemicals include detergents, insecticides, pesticides etc, while inorganic include industrial bi-products, fertilizers etc.
