Study of impact of assessment of anthropogenic effluents on asan river in Dehradun district were taken in two different month of the year, in the winter (feb.) and the summer (june) regarding its physical chemical and biological properties. The fluxing of the natural as well as anthropogenic waste cause disturbance in its composition. The Physico- Chemical Parameters evaluated the deterioration in some parameter, due to the anthropogenic waste as well as natural waste. The Aquatic Diversity is depleting day by day because the abiotic factors have direct affect on the biotic factors. The impact in the physic- chemical parameters results in unsuitability of water for the designated use. The Planktonic Diversity has been affected in past few years due to alarming rate of the toxic pollutants as observed in the planktonic diversity analysis. Many of the common species have been extinct and some are going to be extinct in few years. Due to the habitat loss the disturbance is caused in the ecology of the river and affects the Biodiversity of the River. There tendency of contamination of pollutants or toxicity increases during the summer because the solubility of pollutants increases as the temperature increases. The depth level is affected by rise in temperature, as result habitat loss of the fishes.
