“…The main risk of filter systems is through increased handling and storage of water within the household, and past studies have shown that household storage and handling is a significant source of contamination, perhaps the major source (Molbak et al 1989). This assumption is supported by a field study evaluating arsenic removal systems in Bangladesh, which found that such systems had higher levels of microbial contamination in the filtrated water than in the tube wells from which the water was taken (Sutherland et al 2002) and may therefore increase the risk of water-related infectious disease.…”

“…[16][17][18][19] Publicly available data on water quality in Monrovia, which has a history of cholera outbreaks, have been restricted to studies of the informal settlement of West Point. [20][21][22][23] Both cities have planned or ongoing investments in municipal water infrastructure. In Port Harcourt, the Urban Water Sector Reform and Port Harcourt Water Supply and Sanitation Project and Urban Water Sector Reform Projects (2014-2019) include support from the African Development Bank and the World Bank to rehabilitate and expand the public piped water supply and construct sanitation infrastructure.…”

Abstract. Establishing and maintaining public water services in fragile states is a significant development challenge. In anticipation of water infrastructure investments, this study compares drinking water sources and quality between Port Harcourt, Nigeria, and Monrovia, Liberia, two cities recovering from political and economic instability. In both cities, access to piped water is low, and residents rely on a range of other private and public water sources. In Port Harcourt, geographic points for sampling were randomly selected and stratified by population density, whereas in Monrovia, locations for sampling were selected from a current inventory of public water sources. In Port Harcourt, the sampling frame demonstrated extensive reliance on private boreholes and a preference, in both planned and unplanned settlements, for drinking bottled and sachet water. In Monrovia, sample collection focused on public sources (predominantly shallow dug wells). In Port Harcourt, fecal indicator bacteria (FIB) were detected in 25% of sources (N = 566), though concentrations were low. In Monrovia, 57% of sources contained FIB and 22% of sources had nitrate levels that exceeded standards (N = 204). In Monrovia, the convenience of piped water may promote acceptance of the associated water tariffs. However, in Port Harcourt, the high prevalence of self-supply and bottled and sachet drinking water suggests that the consumer's willingness to pay for ongoing municipal water supply improvements may be determined by service reliability and perceptions of water quality.

“…Women used to carry it on their backs to fetch and keep water from spring, to prepare and keep foods, to keep leftovers fresher [2]. Despite its importance, food spoilage is the major drawback which limits its use in African rural area [3]. One of the most promising innovations in food packaging is the use of nanotechnology to develop antimicrobial packaging [4].…”

With the aim of ameliorating its preservation capacity, silver nanoparticles (0 -100 nm) with 99.9% purity and 35 nm average particle size, were used as building material for earthenware jar, an extremely old container which is still used in rural African villages specifically in North Cameroon. Earth material was dissolved in water at the weight ratio of 5% to 10%. Silver nanoparticles were then added to the mixture and stirred to prepare 1% to 5% Ag/Earth paste (1 to 5 ppm). A grounded metal rotating drum was used to prepare earth embedded nanosilver plates. An n-order mathematic expression was used to evaluate the shelf-live quality and deterioration rate of sorghum porridge preserved in this African earthenware container imbedded with nanosilver particles. Accelerated shelf-life testing was used to predict the shelf life of the product at usual rural storage conditions. The used Arrhenius model indicated that the shelf life of the sorghum porridge stored in African earthenware container imbedded with nanosilver particles can be extended to 14 days at 4˚C ± 1˚C, 6 days at 15˚C ± 5˚C, and 4 days at 30˚C ± 2˚C. The calculated Q10 values were found to be in the range of 1.5 -2.0.
