Abstract :

Heavy metal concentrations of hand dug wells from eight locations within Portharcourt metropolis was studied. About sixteen hand dug well water samples were analysed. The samples were analysed for the following physicochemical parameters such as Temperature, pH value, total dissolved solid and conductivity within 24 hours of sampling using Standard methods. The metal cations were determined using the A.A.S method, Hardness, Chloride and Bicarbonate concentrations were determined using Titrimetric method, Sulphate was determined by spectrophotometric method while Nitrate was determined as Nitrogen content using the Kjedhal method. From the obtained results, most physicochemical parameters were found to be within the WHO acceptable limits for drinking water in all sample location. Rumagbo and Elewere has the highest (108.5mg/L) and lowest (36.08mg/L) concentrations of HCO3- respectively, the highest concentration of SO42- was recorded in Waterline (72mg/L). Cl- (91.5mg/L) and NO3- (0.05mg/L) have their highest concentrations observed at Eligolo, the highest concentration for F- (6.85mg/L) was obtained in Rumuola.Mn, Cd, Fe and Pb ions concentration were found to be highest in water samples from Eligolo, As ion concentration (0.75mg/L) was found to be highest in Rumuola, lowest in Elewere (0.38mg/L). All reported concentrations were above the WHO limits of heavy water concentrations in drinking water. The results obtained from this study suggest a significant risk to the population given the toxicity of these metals and the fact that for many, hand dug wells and bore holes are the only sources of their water supply in this environment.
