SEASONAL VARIATION OF PHYSICO CHEMICAL PROPERTIES OF GROUND WATER ALONG THE VRUSHABHAVATHI RIVER STREAM

M.Harish Raju, ET Puttaiah

Water is a crucial constituent of the atmosphere and it sustains life on earth. For families of millions of rural and urban areas, the tube well water is the source for domestic use. According to one of the surveys ground water accounts for the 50% of urban water requirement and 80% of rural domestic needs. Keeping in view of the above, an attempt was made here to evaluate the physico-chemical properties of twenty four ground water samples along the Vrushabhavathi river stream in the pre monsoon season of 2009. The investigator carried out to study and analyse the level of contamination in the tube well water sample by determining the different physico – chemical parameters namely, Temperature, turbidity, pH, TDS, salinity, EC, total hardness, total alkalinity, chloride, fluoride, calcium, magnesium, sodium, potassium. The results were compared with standard prescribed by BIS & WHO. It was found that some samples of underground water were contaminated and few fall within the permissible limits of the above said standards.
