Water in its natural form contains number of salts, alkalies, microbes and particulate pollutants. Due to industrialization and other anthropogenic ac tivities; the purity of water is critically threatened. Due to the increasing relevance of thes e, the necessity of water analysis is felt desirable. Also the contents vary from place to pla ce. Analysis of water in 20 km radius around Lonand was analyzed for the pH, conductivity, solub le electrolytes like sodium, potassium, chlorides, calcium. The microbial investigation was done to see the safety of water. The present investigation provides the data for pH, conductance , hardness, Na + , K + , Cl - , Ca ++ ions and microbiology including Klebsiella and E.coli estima tion. The experimental observations show high variation of conductance, slight variation in pH in the local reservoir waters. As water is an indispensible part of all the processes, its proper analysis and treatment is necessary.
