A SYSTEMATIC STUDY OF WATER POLLUTION IN JHARKHAND ON THE BASIS OF WATER QUALITY PARAMETERS

The addiction of various kinds of pollutants and nutrients through the agency of sewage, rainwater, and flood, agriculture runoff, human activities etc., into the water bodies, brings about a series of changes in the physicochemical conditions of water and bottom sediment properties of the aquatic system. Among the various physico-chemical factors temperature, turbidity, PH, dissolved gases, alkalinity, different ions, B.O.D., and C.O.D. exert their influence individually and synergistically while the nutrient status such as phosphate, nitrogen, silicate and organic carbon determine the range of biota.
