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 […]
ANTHROPOGENIC IMPACTS ON THE WATER QUALITY OF ABA RIVER, SOUTHEAST NIGERIA
Abstract A stretch of Aba River, southeast Nigeria was studied in four stations from November 2014 to August 2015 to identify the major anthropogenic activities and their impact on the water quality. A number of major anthropogenic activities were identified; some were regular and persistent such as washing of clothes, rugs/carpets and cars as well […]
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 […]
WATER QUALITY ASSESSMENT OF HAND-DUG WELL IN SABON-GARI, ZARIA, NIGERIA
Abstract This study examined the quality of hand-dug wells in Sabon-Gari area of Zaria, Nigeria. Three sets of sampled hand dug-wells were used for the study. They are small, medium and large wells classified based on their diameter. Water samples were collected from twenty-seven (27) different wells at strategic locations in the city to ascertain […]
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 […]
MICROBIAL LOAD OF TWO PALAEMONID PRAWNS AND THE WATER SAMPLE FROM OVIA RIVER, NIGER DELTA, NIGERIA
Abstract A comparative study of the Microbial load of two palaemonid prawns and water samples of Ovia river, Edo state were analysed using standard methods. Total viable microbial count ranged between 1.62 x 105 and 5.58 x 105cfu/g in all samples. The highest mean bacteria count 3.27x 105cfu/g was found in the gills of M. […]
