ABSTRACT

 

The study was conduct to examine the effects of urban wastes discharged into some streams in Enugu, the capital city of Enugu State of South Eastern Region of Nigeria. The riversí water samples were analyzed for some physicochemical features using standard methods. The results show gross pollution of the surface waters at the city centre. The turbidity, colour, EC, TDS and pH values ranged from1500 – 1930.7 NTU, 650 – 2850 Pt – Co, 29.80 – 1011.40 µS/cm, 158.3 – 1000.20 mg/l and 5.2 – 8.0 mg/l respectively. Iron, copper, manganese and lead had concentration ranges of 6.24 – 27.36 mg/l; 2.28 – 5.98 mg/l, 1.10 – 3.05 mg/l and 3.02 – 5.21 mg/l respectively at the city centre sample location. However, the values of the examined anions except nitrate were within the recommended limit. The rivers showed some recovery at a point after the city centre. The results raise concern considering the fact that majority of the urban dwellers depend on these surface waters for domestic, agricultural, and industrial uses.
