Specific tests conducted on the modified samples include grain-size distribution, Atterberg Limits, Proctor Compaction tests, and California Bearing Ratio tests. Lateritic obtained from Agbara, South-West Nigeria pulverized materials gathered construction site rubbles were used for experiment. The mixed 0 to 30% at an incremental rate 5%. From analyses test results, it found that Liquid...

This study investigates the effects of indiscriminate disposal abattoir waste into water bodies in Aregbe area Osogbo capital city Osun state, Nigeria. The samples for were gotten from point source streams and wells close proximity to facility. physiochemical bacteriological parameters analyzed compared World health organization limits discharge use. observed physicochemical Color, Odor, Temperature, pH, Alkalinity, Turbidity, Total hardness, Appearance, Calcium Hardness, Chlorine ion,...

Constant drinking water monitoring schemes are necessary because hazardous substances tend to enter bodies through geodetic and anthropogenic sources. The main goal of this study was evaluate the human health risk assessment posed by high fluoride iron concentration in tap used for domestic activities consumption. In study, varied at different locations, ranging from 0.48 mg/L 1.84 with an average value 1.23 while that ranged 0.02 2.96 mg/L. cluster analysis displayed three popular groups...

Some water-use practices taking place along River Atuwara are conflicting and detrimental to public health the environment.The Ogun State Water Corporation (OGSWC), which has responsibility of supplying piped water residents industrial firms, also withdraws raw from Atuwara.However, OGSWC low capacity meet demand, thus many residents' recourse alternative sources including withdrawing river for domestic purposes.At upstream section Atuwara, however, waste deposits illegal discharges effluent...

This paper investigates strength properties of some selected cement brands for self-compacting concrete application in pavement construction. Three each Portland limestone grades, CEM II/A-L 42.5 (Brand A), II/B-L 32.5 B) and C), were used. Rheological test was carried out using the L-Box, V-Funnel slump cone while compressive flexural tests out, on hardened concrete, at 3, 7, 14, 21 28 days. Brand A exhibited highest right from 3rd day maintained this performance through maturity (the 28th...

With the increase of industrial growth within developing countries, there is a large tendency for increased pollution area.The surrounding rivers may be one culprits serving as waste stream; however, these are used agricultural, domestic and recreational purposes, cautionary measure, preliminary assessment River Atuwara was carried out to know its status using water quality parameters such dissolved oxygen (DO), pH, biochemical demand (BOD), total solids (TDS), electrical conductivity (EC),...

Compacted clay soils are commonly used as landfill liners. This research work was aimed at investigating the suitability of sawdust amended lateritic a liner to adsorb Pb and Cd, thereby protecting underground water. Index properties, compaction, strength permeability tests were conducted on unstabilized stabilized in order determine effects geotechnical properties clay. Batch kinetics utilized capacity sawdust-amended Cd. The soil, classified A-7-6 CH by AASHTO unified soil classification...

The aim of this paper was to study and predict the self-purification capacity River Atuwara. This done primarily by measuring Dissolved Oxygen (DO) downstream a pre-selected pollution discharge point on Atuwara then predicting same using modified Streeter-Phelps equations. Other data gathered from each 17 sampling stations used in analysis included Biochemical Demand, (BOD), pH, stream velocity, depth distance. Predicted DO deficit trend lines were first fitted retaining original re-aeration...

Frequent disposal of effluent in rivers or streams vicinity where the inhabitants rely majorly on it for domestic and agricultural purposes is dangerous, that makes relevant precise modelling dispersion coefficient number.This will reduce under-estimation over-estimation this parameter as well frequent pollution assessment which have proven not to be sustainable.However, obtaining a model include all required still process.This study considered effect varying roughness-which true nature its...

This study was carried out in order to determine cement, lime and bitumen prerequisite of some lateritic soil specimens as sub base materials. Soil A, B, C collected from Dual carriageway road construction project at Estate Iwo road, Osogbo, Osun state stabilized with 0, 3, 6, 9, 12% bitumen. Various laboratory test conducted on the specimen such California Bearing Ratio (C.B.R), Compaction, Atterberg's limit particle size distribution. The investigation revealed that beneficial effects were...

The efficiency of a reed bed system in the treatment wastewaters from premises new Residential University Community was studied. raw influent and treated effluent samples six concrete tanks series, each with four cells containing water hyacinth weeds, Eichornia crassipes, were characterized using standard methods to determine their bacteriological quality, BOD5, COD, total solids volatile organic concentrations. Dissolved ferric ions selected heavy metals also determined. impact on receiving...

Vast volumes of freshwater can be conserved if the practice re-using wastewater is encouraged.In this study, quality from Covenant University campus was assessed to determine its suitability for landscape irrigation purposes.The university uses a constructed wetland (CW) method in treating both black-water and grey-water (wastewater).An estimated 874,081 litres/day generated treated as 2013, with nearly all volume discharged without being re-used.To assess reuse, duplicate grab samples...

Wastes that have cementitious properties can become a useful source of cheap materials for soil improvement, thereby reducing the cost construction projects on sites unsuitable soils.This research work investigated effects application calcium carbide residue (CCR) to tropical its geotechnical in order assess suitability stabilized use as road pavement material.Tests determine grain size distribution, specific gravity, liquid and plastic limits, compaction, California bearing ratio (CBR)...

The need for treatment of municipal wastewater prior to its disposal is important. One method used treating wastewater that a constructed wetland system (CW). The use CW has attracted interest in developing nations due to its operational efficiency and cost effectiveness. This paper examines an existing in order determine effectiveness the removal of pollutants from sewer feeds into major river system Nigeria. CW, which employs hydrophytes to degrade facility nearly 10,000 people,...
