Solid Waste Management, Surface Water Quality and River Basin Contamination in Akwa Ibom State: Case Study of Ikpa River Catchment
Abstract
Solid waste management is one of the problems confronting many developing countries of the world. Recent events in major urban centres have shown that the problem of waste management has become too complex to handle and beyond the capacity of city authorities, federal governments, State and professionals agencies. The study therefore examines solid waste management, river basin contamination and surface water quality and river basin in Ikpa River Basin Catchment, Akwa Ibom State aimed at examining the variability in the Physico-chemical parameters at different sections of the stream channel, examine and compare the difference in the quality of sampled surface water with World Health Organization and Nigeria Standard for Drinking Water Quality as well as assess the impacts of waste disposal on health status of residents in the area. Laboratory analytical method and survey techniques were adopted closer to the dumpsite and decreases with distance away from the dumpsite. Hence, the result indicates that there is a significant variability in the physico-chemical parameters at different segments of the stream channel. More so, with some of the physico-chemical properties (colour, Phosphate, Calcium and Magnesium. More so, Nickel and Cadmium) exceeding WHO limits, the study shows that the concentration of the physio-chemical properties of the stream is deeply affected by the dumpsite. Findings from the study also indicates the negative impact of waste dump on surface water quality to include pollution of drinking water, loss of aesthetic value, spread of waterborne diseases, destruction of aquatic flora and fauna, threat to economic life of the people and siltation of the stream. As a result of this waste dump, the river eacosystem is under serious threat because of a break-in the food chain causing declining fish stocks, death of aquatic life, and destruction of aquatic flora and fauna. Furthermore, unsanitary conditions and water
