WATER QUALITY ANALYSIS AND EVALUATION USING GRAPHICAL METHODS: A CASE OF LAKE BESEKA, ETHIOPIA

Abstract Water quality analysis and evaluation processes are very important to understand the quality status and trend of water resources. Moreover, a documented water quality data can serve as an input in identifying the geochemical composition and origin of water resources. The aim of this paper was thus to analyze and evaluate the water quality […]

AN EVALUATION OF ADEQUACY OF WATER POLICY STIPULATION IN ENSURING WATER SECURITY IN THE CONTEXT OF CLIMATE CHANGE

Abstract The aim of the study was to establish how responsive the Water Policy (2010) is to ensure water security in the context of climate change. The objectives of the study were to establish if the water policy addresses water security and to determine whether the water policy addresses challenges in the climate change context […]

SEDIMENT INFLOW ESTIMATION AND MAPPING ITS SPATIAL DISTRIBUTION AT SUB-BASIN SCALE: THE CASE OF TENDAHO DAM, AFAR REGIONAL STATE, ETHIOPIA

Abstract Sedimentation is a major problem of reservoir operation in Ethiopia. Deforestation, overgrazing and poor land management practices are some that accelerate the rate of erosion. The topography of Ethiopia in general and TDW in particular is undulating and local farmers commonly cultivate on the hilly sides causing easy topsoil wash away. This study aims […]

QUANTITATIVE ESTIMATION OF POLLUTION IN GROUNDWATER AND SURFACE WATER IN BENIN CITY AND ENVIRONS

Abstract Microbiological and physico-chemical analyses of groundwater and surface water samples collected from different parts of Benin City were carried out to investigate their pollution load. Microbiological analyses were carried out using pour plate method and most probable number (MPN) technique while physico-chemical properties were investigated using standard analytical methods. Microbial colony counts were most […]

AN ASSESSMENT OF SEASONAL VARIATIONS IN PHYSICO-CHEMICAL CHARACTERISTICS OF UNDERGROUND WATER IN A GROWING TROPICAL CITY IN NIGERIA

Abstract The quality of underground water is influenced by natural and anthropological factors which need to be constantly monitored in order to safeguard human health. This work investigated seasonal variations in well water in Iwo town, Osun State Nigeria. A total of 15 water samples were collected from hand-dug wells from each of the political […]

ASSESSMENT OF WATER QUALITY OF OBUEYINOMO RIVER, OVIA NORTH EAST LOCAL GOVERNMENT AREA, EDO STATE, SOUTHERN NIGERIA

Abstract This study was carried out to assess the water quality of Obueyinomo River using water quality index. Ambient and water temperatures were determined in-situ while total dissolved solids (TDS), total suspended solids (TSS), total solids (TS), turbidity, pH, conductivity, hardness, alkalinity, dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), chloride, nitrate, phosphate, calcium and magnesium […]

ASSESSMENT OF GROUNDWATER QUALITY AROUND A PETROLEUM TANK FARM, IN IFIE COMMUNITY AND ENVIRONS, WARRI, SOUTHERN NIGERIA

Abstract Investigation of the physical and chemical properties of groundwater around a Petroleum Tank Farm was carried out between January and August, 2015 to assess the suitability of the borehole water for drinking and other domestic uses. The results show that pH of water was acidic with values ranging from 4.62 to 6.87, EC (33.00–206.00 […]
