Natural water occurring in the environment is not chemically pure water. While circulating in the environment water contacts with atmosphere, rocks and soil. In this way many different compounds pass in to the water, either inorganic or organic. Water is one of the most important and abundant compound of the ecosystem, it profoundly influence life due to rapid industrialization and indiscriminate use of chemical fertilizers and pesticides in agriculture are causing varied pollution affects the entire biosphere, plants and organisms living in the bodies of water. Its effect is damaging to the natural biological communities. Present investigation to study of Khadakpurna reservoir, district Buldana. (M.S.) with regards to various physico-chemical parameters were carried out period of two years such parameters are temperature, pH, Transparency, Turbidity, TDS, Conductivity, Alkalinity, Chloride, Hardness, Dissolve Oxygen, Carbon dioxide, Iron, Ammonia, Nitrite, Nitrate, Sulphate, Silicates, Phosphate, Biological Oxygen Demand, Chemical Oxygen Demand. All the parameters are in acceptable limits hence, from the study it has also been concluded that water from Khadakpurna reservoir is suitable for drinking and fishing purpose.

Introduction:- Water is a universal and the most vital solvent essential to the existence of all living organisms particularly man (Adeneyi, 2004). In India, there are several large reservoirs exist besides large natural lakes and innumerable small tanks and ponds. Reservoirs are made by constructing dams across the river to serve a variety of purposes like industrial process, irrigation, navigation, domestic water supply, fish culture recreation and generation of hydroelectricity (Raoet al., 2003). Water covers about 70% of the earth surface only 2.53% is fresh water while the remaining is salt water (UNESCO, 2003). However the water of the Ponds, Lakes, Reservoirs, and Rivers are polluted mainly due to discharged waste water from residential areas, solid wastes, sewage outlets, washing detergents, automobiles oil wastes, fishing facilities and agricultural pesticides from land (Bhuiyan and Gupta, 2007). Impairment of water quality in reservoir arises largely from anthropogenic contamination and natural mineralization. The physico-chemical parameters serve as pollution indicator in water quality monitoring which is a fundamental tool in the management of fresh water resources, monitoring can be conducted for the purpose of identifying trends in water quality over time, to study Corresponding Author:-Mhaske T.
