Investigating the potability of water from dug wells: A case study of the Bolgatanga Township, Ghana
The aim of this study was to assess the levels of some physico-chemical and microbial water quality parameters in fifteen hand-dug wells in Bolgatanga of the Upper East region of Ghana. The effects of seasonal variation and proximity to pollution sources on the concentrations of some parameters of the well water samples were analysed. The results revealed that, total and faecal coliforms in all fifteen samples exceeded...

A critical analysis of physiochemical properties influencing pit latrine emptying and feacal sludge disposal in Kampala Slums, Uganda
Inadequate information on physiochemical properties of faecal sludge leads to inappropriate design of pit emptying devices and poor faecal sludge disposal contributing to environmental pollution. This study undertook a critical analysis of physiochemical properties of feacal sludge that influence design and performance of pit emptying devices and faecal sludge disposal for improved faecal sludge management in urban...

An evaluation of biogas production from anaerobic digester of a constructed wetland domestic wastewater treatment plant
Domestic wastewater treatment using constructed wetlands have been found to be very efficient and cost effective. Primary treatment facilities such as anaerobic digesters have been reported to reduce the organic load of wastewater before entering the constructed wetland systems. It has also been established that biogas is a product of organic matter decomposition under anaerobic condition. In this study, we evaluated...

Atmospheric ventilation corridors and coefficients for pollution plume released from an Industrial Facility in Ile-Ife Suburb, Nigeria
This study presents a comparative investigation of atmospheric ventilation corridors and coefficients for gaseous pollution plume released from an isolated industrial facility into the ambient air of the host community in Ile-Ife suburb, southwest Nigeria. For the months of September to December in the year 2012 and 2013, measurement of surface layer atmospheric parameters made from an instrumented mast located near the...

Evaluation of fluoride enrichment processes in groundwater of Chimakurthy granitic pluton complex in Prakasam District India
Hydrogeochemical evaluation of aquifers belonging to Chimakurthy granitic pluton complex reveals wide spatial and temporal variation in F- distribution. F- concentration in groundwater of different aquifers varies from < 0. 50 to 9.84 mg/l. Among three sampled episodes, the mean value of F- is high in July 2010 and 61% of samples have values above maximum permissible limit as per the Bureau of Indian...

Challenges of water accessibility in the urban centres of Malawi: A case study of Blantyre City
This study assesses challenges of water supply to urban areas of Malawi since factors obstructing water availability, indicators of water service’s delivery, trend of tariff structure and cost recovery’s mechanisms and water governance in Malawi have been poorly assessed in the past despite the fact that the country has engaged itself in the improvement of urban water policy. The study was conducted in...
