Seasonal Variation of Groundwater Quality in and Around Laharpur Reservoir Bhopal

Abstract

Water, being a universal solvent, has been and is being utilized by mankind time and now. Of the total amount of global water, only 2. 4% is distributed on the mainland, of which only a small portion can be utilized as. fresh water. The available. fresh water to man is hardly 0.3-0.5% of the total water available on the earth and therefore, its judicious use is imperative. Variations in availability of water in time, quantity and quality can cause significant fluctuations in the economy of a country; the definition of water quality is very much dependent on the desired use of water. Therefore, different uses require different criteria of water quality as well as standard methods for reporting and comparing results of water analysis.
