“…Holy water from natural springs Holy water is a common element of ritual prayers, spiritual cleansing and healing rituals among Orthodox Christian and Muslim Ethiopians throughout the country. 31,62 Holy water is frequently consumed, poured over or bathed in by people who are sick (including with gastrointestinal diseases 63,64 ) or who exhibit symptoms of a wide range of mental illnesses and spiritual afflictions. Holy water collected from natural springs is often stored for ritual use in churches, monasteries and mosques throughout the country.…”

The current cholera outbreak in the Federal Democratic Republic of Ethiopia began in August 2022. As of April 2024, active outbreaks had been recorded in most regions of the country, including: Amhara; Dire Dawa; Harari; Oromia; Southern Nations, Nationalities and Peoples’ Region (SNNPR); Somali and Tigray. This brief has been developed to support response efforts by exploring the social and structural determinants and community dynamics of cholera infection and mortality in Ethiopia. Socio-cultural and epidemiological information, academic and grey literature and consultations with cholera response experts in Ethiopia have been used to develop the brief.

Sacred wells and springs are important cultural features in many societies. A recent study in Ireland may be the first detailed countrywide investigation of the hydrogeology and water chemistry of sacred wells. Key findings are discussed in relation to case studies elsewhere. A wide range of hydrogeological settings are represented. There is evidence of anthropogenic impacts at many sacred springs and wells. Communication of potential health impacts is necessary but challenging, because of the sensitivities surrounding these sacred water sources.

Oxidative leaching is an inexpensive alternative to using chemical cyanide extraction methods for gold from low-grade gold sulfide. Oxidation of finely ground gold-bearing ore by Acidithiobacillus ferrooxidans was evaluated in terms of cell density, pH, and leaching efficiency of Fe and Au in shake flask experiments. The compositional and elemental analyses of the beneficiated ore were analyzed using XRD and EDXRF spectroscopy. The ore’s primary constituents are gold (4.356 mg/L), silicon, iron, and sulfur (62.456, 15.441, and 7.912 wt%, respectively). XRD spectra, the main phases of the concentrated ore, showed that the major components of the ore were quartz, syn, silicon sulfide, pyrite, and polymetallic elements such as silderenrite, gismondine, siderenikite, hematite, and syn. The experimental results, with Acidithiobacillus ferrooxidans bacteria and blank, were evaluated. The pH of the blank remained nearly constant, and the pH of the bioleached was occasionally lowered. The A. ferrooxidans strain always grew better throughout the bioleaching process. For the A. ferrooxidans strain, the cell density of cells reached a maximum of 90.00 × 106 cells/mL after the 11th week and decreased to 87.00 × 106 cells/mL after the 12th week. The decrease in cell density may be due to the presence of polymetallic elements such as Al, Cr, Ti, and Ni, leading to reduced metal tolerance of the A. ferrooxidans strain. In the A. ferrooxidans leaching process, the maximum total iron and gold extraction reached 92.16% (14.23 mg/L) and 99.97% (4.355 ppm), respectively, after the 11th week, and leaching tends to decrease up to 14 weeks, which may be due to the formation of secondary minerals. More research will be performed to optimize the procedure and leaching kinetic, examine the impact of metal content, and take into account the potential for bioleaching process pollution in addition to the amount of gold recovered.
