Comparative analysis of seasonal variations in physico-chemical parameters from Girna, Ozarkhed, Chankapur and Gangapur reservoirs in Nasik district.(M.S.)

Abstract

The seasonal physico-chemical parameters like temperature, pH, total alkalinity, dissolved oxygen, total hardness, chlorides, salinity and electrical conductivity were determined seasonally from Girna, Ozarkhed, Chankapur and Gangapur reservoirs of Nasik district. Results of the present study indicated that the mean values of temperature, pH and total alkalinity were highest in summer season and lowest in winter season, mean values of dissolved oxygen was highest in winter season and lowest in summer season. The mean values of total hardness, salinity, chloride and electrical conductivity were highest during summer season and lowest during monsoon, in surface water sampled from four studied reservoirs. Thus result clearly indicated that the surface water of Girna reservoir was more polluted than other three reservoirs, while surface water of Gangapur reservoir was less polluted than other three studied reservoirs.
