Ground water quality evaluation at suburban areas of Lucknow, U.P., India (original) (raw)

Ground water is vital for the survival of all living beings on the planet for its usages in drinking, domestic, irrigation and industrial purposes. Globally, it has become the most concerned natural resource as rapid urbanization and industrialization are causing threat to the quality of water. Lucknow is the capital of most populated state of India, facing tremendous pollution pressure on the environment because of the over exploitation of the natural resources. Among all water is the most valuable natural resource for the survival of living beings on the earth. The aim of present study was to examine the variations in the physio-chemical properties of the ground water of suburban areas of Lucknow. Sixty six samples were taken from twenty two sampling sites, dividing them in four zones (North, South, East and West) and were analyzed to assess the quality of ground water as deemed fit for drinking purpose. The physical parameters like Total Dissolve Solids, Total Suspended Solids and Total Solids were found to be in range of 50.98-1247.01, 200.17-602.67 and 554.89-1590.01 mg/L respectively. The chemical and biological parameters including pH, EC, alkalinity, hardness, chloride, sulphate, N2-NO3 2-, NH3 – N2 , total P and MPN were found to be in range of 6.60-7.10, 448.33-1590.01 µmoh/cm, 212.67-408mg/L, 50.57-134.00mg/L, 17.06-150.81mg/L, 1.85-88.00mg/L, 0.24-85.01mg/L, 0.70-1.43mg/L 0.44-17.16 mg/L and 0 to >8 respectively. Except MPN for Bhitauli, Madiyav, Kallipaschim, Darogakheda and Ganeshpur, most of the physio-chemical and biological parameters were found to be range of the desirable limits given by Bureau of India Standards.
