Physico-chemical and heavy metal analysis of ground and surface water obtained from some selected areas in Kaduna metropolis

Water samples from 10 selected boreholes and 3 hand-dug wells within the three areas of Kaduna Metropolis were collected; Physico-Chemical parameters and heavy metals were determined. The results of the Physico-Chemical analysis were obtained in the following range, temperature (17.3-20.9), conductivity (44-60 mV), alkalinity (184-688 mg/l) BOD (6.5-15.4 mg/l) all within the set limit of WHO standard, TDS value (1197-2340 mg/l) fell above the set limit of WHO standard , the chemical constituents were obtained in the following range pH (7.25-7.67), Magnesium (1.28-6.08 mg/l), Calcium (0.12-0.90 mg/l), Nitrate (0.03-0.32 mg/l) with Chloride value (2.33-495.6) above the set limit of WHO standard, the highest value of 0.1241mg/l was found in Chromium. the concentrations of heavy metals (mg/l) Chromium, Iron, Lead, and Copper in the Groundwater were found in the following range, lead (0.0001- 0.120 mg/l), Chromium (0.0001- 0.124 mg/l), iron (0.0191- 0.3547 mg/l) and Copper (0.0006- 0.0070 mg/l). The results obtained fell within the limit set by World Health Organisation with the exception of Chromium which was 0.124 mg/l in sample SH3 and Lead which was in sample MF2. Which these two had concentrations above the limits set by World Health Organisation.
