Irrigation water quality analysis of Mitheu Stream in Machakos Municipality, Kenya
Water samples for physico-chemical, heavy metals and bacteriological analyses were collected from 4 selected points along Mitheu Stream flowing through Machakos Municipality once every month from June 2019 to September 2019. The samples were analyzed in Kenya Plant and Health Inspectorate Service and Water Resources Authority laboratories then data subjected to one-way analysis of variance to test significant...

An appraisal of high definition survey approaches in subsidence monitoring of crude oil storage tanks
Vertical and horizontal motion of the solid earth surface due to geological and geodynamical phenomena are generally consequences of terrain deformation. Variations as a result of the deformation affect structures, particularly large storage facilities that are steel and/or concrete in nature. The criticality of these phenomena underscores the need to carryout regular measurements and monitoring of its effect in all...

Effect of agitation on the process of bi methanization of sludge from low-temperature wastewater treatment plants
Wastewater treatment is a serious environmental problem, especially in developing countries such as Morocco. Their discharge into the natural environment has negative impacts on water resources and the environment. They are therefore purified to reduce the concentration of the main pollutants. Often biological remediation is used when wastewater contains biodegradable organic pollutants. This generally leads to treated...

Assessment of the health impacts of WASH interventions in disaster-prone communities in three regions of Northern Ghana
This study evaluated the health impacts of WASH interventions in 9 intervention communities against 9 control communities in disaster-prone areas in northern Ghana. We extracted community-specific data on patient-reported cases of WASH-related diseases from health facilities in the study areas. Also, we used key informant interviews and household questionnaires to seek information for validation. The impact was measured...

Assessment of chitosan – coated Aspergillus–niger as biosorbent for dye removal and its impact on the heavy metal and physicochemical parameters of textile wastewater
Efficiency of biosorbent from chitosan coated dead fungal biomass of Aspergillus niger for dye removal with its impact on metals and physicochemical parameters of textile industry wastewater were assessed. Dye and metal concentrations of wastewater were determined using UV and Atomic Absorption Spectrophotometers respectively, before and after column biosorption using simulation optimized parameters with biosorbent....
