Seasonal variations of ground water quality and its agglomerates by water quality index

Water is a unique natural resource among all sources available on earth. It plays an important role in economic development and the general well-being of the country. This study aimed at using the application of water quality index in evaluating the ground water quality innorth-east area of Jaipur in pre and post monsoon for public usage. Total eleven physico–chemical characteristics; total dissolved solids, total hardness,chloride, nitrate, electrical conductance, sodium, fluorideand potassium, pH, turbidity, temperature) were analyzed and observed values werecompared with standard values recommended by Indian standard and World Health Organization. Most of parametershow higher value than permissible limit in pre and post monsoon. Water quality index study showed that drinkingwater in Amer (221.58,277.70), Lalawas (362.74,396.67), Jaisinghpura area (286.00, 273.78) were found to be highly contaminated due to high value of total dissolved solids, electrical conductance, total hardness, chloride, nitrate andsodium. Saipura (122.52, 131.00), Naila (120.25, 239.86), Galta (160.9, 204.1) were found to be moderately contaminatedfor both monsoons. People dependent on this water may prone to health hazard. Therefore some effective measures are urgently required to enhance the quality of water in these areas.
