| Abstract: | A survey of Nworie River was conducted in order to establish the current pollution levels of the river. An attempt has been made to the assessment of the potability of Nworie River, to treat the water sample by chemical method. The physical, chemical and microbiological parameters were investigated on the water samples collected from three different locations namely upstream (NRSW1), midstream (NRSW2) and downstream (NRSW3) Nworie River and the mean concentrations were obtained. The turbidity value, 2-20-3.50 NTU; temperature, 28.50-29.00oC; pH value, 6.18-6.49; electrical conductivity, 57.90-87.70µS/cm; TDS 26.63-40.34 (mg/l); TSS, 8.10-13.20 (mg/l); total alkalinity, 28.00-44.00 (mg/l); total hardness, 7.60-16.40 (mg/l); calcium hardness 6.98-16.40 (mg/l); magnesium hardness 0.00-0.77 (mg/l); DO, 2.10-2.60(mg/l); BOD, 3.00-5.80 (mg/l); COD, 0.00-48.22 (mg/l); chloride, 15.34-19.88 (mg/l); sulphate, 14.64-28.78 (mg/l); phosphate, 0.37-0.53 (mg/l); nitrate, 3.80-4.70 (mg/l); sodium, 0.00-0.0001 (mg/l); potassium, 2.5493-13.0172 (mg/l); iron, 0.0001-1.6815 (mg/l); and lead, 0.0001-0.0104 (mg/l). Total coliform count; E. coli; salmonella/shigella total count; vibrio total count; faecal coliform growth was confirmed; The results of the analysis were compared with the World Health Organization (WHO) standards and the water was found unfit for human consumption due to high pollution index of 2.15, high concentration of iron, low DO, high COD at the midstream, E. coli, and yeast/mould as a result of dumping of both organic and inorganic wastes into the Nworie River. The product-moment gave the correlation coefficient, r as -0.31, which implies that there is a low negative correlation between X, Y and Z i.e. between the upstream (NRSW1), midstream (NRSW2) and downstream (NRSW3) respectively of Nworie River water samples. Similarly, the test for significance using t-table at 19 degree of freedom at significant levels of 0.05, indicates that there is no significant difference between the mean concentrations of the upstream (NRSW1), midstream (NRSW2) and downstream (NRSW3) of Nworie River. The result of the treated water sample gave the following: The turbidity value,1.58 NTU; temperature, 29.00; pH value, 7.30; electrical conductivity, 116µS/cm; TDS 75.40 (mg/l); TSS, 10.00 (mg/l); total alkalinity, 50.00 (mg/l); total hardness, 3.47 (mg/l); calcium hardness 1.54 (mg/l); magnesium hardness 0.93 (mg/l); DO, 5.60 (mg/l); BOD, 0.25(mg/l); COD, 25.65 (mg/l); chloride, 25.56 (mg/l); sulphate, 0.00 (mg/l); phosphate, 0.60 (mg/l); nitrate, 5.00 (mg/l); sodium, 0.0001 (mg/l); potassium,11.00 (mg/l); iron, 0.2915 (mg/l); and lead, 0.0056 (mg/l). The results of the analysis were compared with the World Health Organization (WHO) standards and the water was found fit for human consumption due to the reduction in iron and COD level and the absence of E. coli and yeast/mould. The study shows the need for adequate waste management system in order to provide good quality water and to prevent the outbreak of pathogenic diseases in the area. |
