To reduce child mortality and improve health in Ghana boreholes and wells are being installed across the country by the private sector, NGO's and the Ghanaian government. Water quality is not generally monitored once a water source has been improved. Water supplies were sampled across Ghana from mostly boreholes, wells and rivers as well as some piped water(More)
This study was carried out on KNUST campus, Kumasi, Ghana, to assess the microbial quality of irrigation water and on vegetables as well as the risk associated with vegetable irrigated farming. Microbiological contamination of irrigation water and lettuce was monitored weekly for two months from eight farms for faecal and total coliform, and helminth eggs(More)
A bench-scale continuous-flow wastewater treatment system comprising three parallel lines using duckweed (Spirodela polyrhiza), water lettuce (Pistia stratiotes), and algae (natural colonization) as treatment agents was set up to determine environmental conditions, fecal coliform profiles and general treatment performance. Each line consisted of four ponds(More)
A batch scale experiment was conducted to determine the effect of pH on enterococci die-off. A continuous flow system was also established to determine the environmental conditions and their effects on enterococci removal. The batch experiment was conducted for pHs: 4, 5, 7, 9, and 11 under light and dark conditions. Enterococci and DO were measured every(More)
This study investigated the possibility of recycling nutrients in human excreta and municipal solid waste for use in agriculture. It reports on the use of drying beds in separating solid and liquid fractions of faecal sludge (FS) so that the solids can be co-composted and the organic matter and part of the nutrients captured for urban agriculture. Sludge(More)
The use of raw sludge spread on land as conditioner and fertilizer has been practised over the years in urban agriculture. However, this raw sludge (biosolids) is associated with a potential health risk as a result of the pathogenic microorganisms it contains. The study considered the dewatering of faecal sludge (FS) mixed with sawdust to produce biosolids(More)
Although dams have beneficial effects, they are also acknowledged as having serious environmental repercussions if they are not properly managed. The objective of this work was to examine the impact of the Barekese Dam in Ghana on the health status of three riparian communities downstream against a control. The environmental health status of the communities(More)
The environmental conditions and pathogen removal in macrophyte (Pistia stratiotes and Lemna paucicostata) and algal-based wastewater treatment systems were determined over a period of 29 days under tropical conditions. The experiment was conducted on a batch scale in 4.5 plastic containers immersed in moist sand beds. A control of raw sewage stored under(More)
BACKGROUND Despite its contribution to global disease burden, diarrhoeal disease is still a relatively neglected area for research funding, especially in low-income country settings. The SNOWS consortium (Scientists Networked for Outcomes from Water and Sanitation) is funded by the Wellcome Trust under an initiative to build the necessary research skills in(More)
This study was conducted in January 2013 to identify risk factors associated with diarrhea morbidity among children younger than 5 years in the Atwima Nwabiagya District, Ghana. A total of 378 households were drawn from four Atwima Nwabiagya District communities in the dry season using a systematic random sampling strategy. Quantitative data was collected(More)
