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 were compared with standard values recommended by Indian standard and World Health Organization. Most of parameter show higher value than permissible limit in pre and post monsoon. Water quality index study showed that drinking water 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 and sodium.Saipura (122.52, 131.00), Naila (120.25, 239.86), Galta (160.9, 204.1) were found to be moderately contaminated for 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. 

Graphical Abstract

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


  • Determined various physico-chemical parameters of groundwater for both pre and post monsoon periods in north-east area of Jaipur
  • The correlation between the physico-chemical parameters to identify the most influencing parameters for water contamination
  • Calculated the water quality index (WQI) to identify the suitability of groundwater for drinking purposes
  • The remedial measures suggestion to enhance the quality of contaminated groundwater
