Investigation of the Impacts of Solid Waste Disposal Sites on Groundwater in Nasarawa Metropolis, Nigeria
Abstract
Population increase generates concerns for waste disposal. Absence of standard sanitary-disposal methods has left many city residents with open dumpsites as their only means of disposing waste, thereby resulting in leachate from the decomposition of these waste materials, which will later pollute underground water. The reserach investigated the effects of solid waste disposal sites on underground water quality through the examination of some physical and chemical properties of water in hand-dug wells around some selected disposal sites in Nasarawa metropolis, Nasarawa State. Three hand-dug wells were sampled at various distances from each dumpsite. The samples were thoroughly tested at the Federal Ministry of water resource, Regional Water Quality Laboratory, Minna, Niger state. The overall quality of the water was determined using the Water Quality Index method. The results showed high degree of non-conformity with W.H.O and NSDWQ standards. The study of chemical properties from the three wells showed that seven (7) parameters (dissolved oxygen, total dissolved solids, total suspended solids, conductivity, chloride, total hardness, manganese) are above W.H.O. limits in some samples. Also the Water Quality Index of the three samples; Unguwar Bai1, Unguwar Bai2 and Student Village which had been calculated to be 1072.2, 1867.1 and 69.85 respectively, were far out of the range of safe drinking water quality (according to Weighted Arithmetic Water Quality Index Rating). The water is therefore not safe for human consumption and there is a serious need to improve its quality. Therefore the need for adequate planning, design and construction vis-a-vis strategic management of waste becomes very crucial.
