Hazardous Effects of Industrial Effluents on Ukwaka Stream and the Ecosystemin Nnewi, Nigeria

Abstract
Careless disposal of untreated industrial waste on surface water might affect the physicochemical characteristics of stream ecosystem. The aim of this study was to evaluate the effects of industrial waste disposal on surface water quality of Ukwaka stream and the soil. Water samples were taken at the effluent discharge points labeled: site A (0m); sites B (300m) and C (600m); and downstream site D (900m) along the stream from the discharge point with geo-reference using Garmin Global Positioning (GPS) reference system (Site A, 6.820 0E, 5.885 0N; Site B, 6.915 0E, 5.996 0N; Site C, 6.911 0E, 5.996 0N; Site D, 6.906 0E, 5.995 0N)., and were analyzed for pH, dissolved oxygen, biological oxygen demand, electrical conductivity, suspended solids, chloride, salinity, phosphate, and heavy metals, in the dry and wet seasons. The results of study showed that the effluents were acidic in both dry and wet seasons on most of sampling stations. While the levels of biological oxygen demand, electrical conductivity, were relatively high in dry season. Water sample was slightly acidic with high dissolved oxygen. There was moderate contamination of the environment by the metals studied. All the metals were high with iron and zinc being exceptionally high and above the specified international standards. This study indicates that industrialization has contributed to the large scale pollution and this polluted water is not good for human consumption. It is therefore recommended that the disposal untreated wastes should be stopped to save the stream water from further deterioration.
