Abstract
This paper focuses on the effects of waste dumps on stream water quality in rural areas of southern Nigeria. The purpose was to evaluate evidence linking surface water pollution to leachate migration from waste dumps. Thirty-two water samples were collected and analysed from eight waste dumpsite environments located on eight widely separated streams. The samples were evaluated for physical, chemical and bacteriological contamination. Eighteen water quality parameters were investigated. The parameters included pH, total hardness, sulphate, alkalinity, manganese, silica, potassium, total dissolved solids, iron, nitrate, calcium, total suspended solids, chloride, magnesium, turbidity, biochemical oxygen demand, Escherichia coil and total coliform count. Results of the analysis revealed the degree of stream water pollution, the critical pollutants and the strategies for managing polluted stream water in the study area. The streams are polluted at many locations and consuming them portends danger from water borne diseases. Eight water quality indicators returned mean values that exceeded the 2011 WHO and NAFDAC standards for drinking water. Strategies which may help to remedy the situation were recommended.
