Investigation of groundwater flow potential in Makurdi, North Central Nigeria, using surficial electrical resistivity method

Vertical electrical sounding (VES) employing Schlumberger electrode configuration was carried out in order to study the groundwater flow potential in Makurdi, north central Nigeria. This was done in thirty locations to determine the aquifer resistivity, thickness, longitudinal conductance, hydraulic conductivity and transmissivity. From the result, the averages and ranges of these parameters were determined. 2D contour...

Groundwater quality degradation due to salt water intrusion in Zanzibar Municipality

Saltwater intrusion problems are widespread where there are over pumping of groundwater from coastal aquifers. Water samples were collected from production boreholes in Zanzibar municipality and analyzed for salinity indication parameters comprising of chloride, electrical conductivity, total dissolved salts and percentage salinity levels. Historical water quality data of boreholes were also collected and used to...

Estimation of methane generation based on anaerobic digestion and mass balance at Kiteezi Landfill, Kampala, Uganda

Kiteezi landfill site is the main solid waste dumping site in Kampala City (Uganda). In this study, the generation of methane from waste at Kiteezi landfill was measured using laboratory-scale anaerobic digestion experiment and estimated using the Mass balance model. The samples were collected in the wet and dry seasons, with five replicates for each season which were processed for further experiments focused on...
