ABSTRACT:

Water quality characteristic's of aquatic environments arise from a magnitude of physical, chemical and biological interaction. Water bodies, rivers, lakes and estuaries are continuously subjected to a dynamic state of change with respect to their geological age and geochemical characteristics. These are influenced by the activities of living things. The dynamic balance in fie aquatic ecosystem is up set by human activities resulting in water pollution. Sometimes biological decomposition of organic matters consumes all the dissolved oxygen, which can not be made up. As a result of O2 depletion, anaerobe biological populations dominate and reduction reactions set in NO3—^NO2"—» NH3—> N2 —>SO24 H2S. This results in the precipitation of heavy metal ions as sulphides which settle at the bottom layer.
