Assessment of Ground Water Quality (A Case Study of Mando, Igabi Local Government Area, Kaduna State)

Abstract

This study shows the assessment of ground water quality in Mando Area of Igabi Local Government Area of Kaduna State. A total of twenty (20) samples of water (Ten (10) bore-hole water samples and Ten (10) hand dug well water samples) were collected randomly from different locations within the study area. The analysis of these samples was carried out in the Water Quality Laboratory of National Water Resources Institute Kaduna except for the the analysis of the heavy metals which was carried out at the Federal Ministry of Agriculture and Rural Development, Kaduna State. The result from the analysis shows differences in the average level of physiochemical and bacteria concentration for both categories of water samples. But this difference in concentration still falls within the permissible limit of both the World Health Organization (W.H.O) and (NSDWQ) standard for water quality, thus acceptable. The concentration of heavy metals like Lead and Chromium is same for both samples in the study area which is above the permissible level of WHO and NSDWQ standards. The average level of physiochemical and bacteria concentration of both categories of samples are thus; for bore-holes water sample: Electrical Conductivity is 109.56 ℳs/cm, Turbidity is 0.07 NTU, Total Dissolved Solid is 54.5 ppm, Temperature is 25.2℃, Colour is 8.6 TCU, Ph is 6.4, Total alkalinity is 51.3, Nitrate is 25.72, Chloride is 22, Total Hardness is 39.52, Salinity is 35.8, Fluoride is 0.53, Iron is 0.012, Sulphate is 3.6, Lead is0.4, Chromium is -0.068, Total coliform is 13.8 and that of the hand dug well in same sequence is thus; 183.39, 1.76, 90.22, 25.15, 14, 6.6, 30.2, 42.56, 23.4, 56.8, 38.7, 0.24, 0.012, 2.3, 0.4, - 0.078 and TNTC.s
