Journal Title:Journal of Chemical, Biological and physical sciences

Water sources available for drinking and other domestic purposes must possess high degree of purity, free from chemical contamination and microorganisms. The rapid growth of urban areas has further affected the water quality due to over exploitation of resources and improper waste disposal practices. The physicochemical status of ground water samples from ten major part of locality along Vaigai River in Madurai city was assessed. The sampling points were selected on the basis of their importance. The physicochemical parameter like, temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), turbidity, dissolved oxygen (DO), total alkalinity (TA), total hardness (TH), calcium (Ca2+) magnesium (Mg2+ ), sodium (Na+),potassium (K+), chloride (Cl-), fluoride (F-), nitrate (NO3-) sulphate (SO4 2-) and chemical oxygen demand(COD) of bore well water were determined. The results were compared with standards prescribed by WHO and BIS. The quality of water was not found suitable for domestic, agricultural and industrial purposes, because of high concentration of total dissolved solids, total alkalinity, total hardness, chloride and COD. It was found that the ground water was contaminated at few sampling sites namely Vandiyur, Viraganur and Silaiman while the sampling sites Thuvariman and Kochadai showed physicochemical parameters within the water quality standards and the quality of water is good and it is fit for drinking and other purpose.
