Ethiopia is one of the developing countries where only 52% of its population have access to safe drinking water. To determine the level of faecal contamination in drinking water, the E. coli has been found to be the most specific indicator. The purpose of this study was to determine household bacteriological drinking water quality and its associated factors in rural North Gondar Zone Ethiopia. A community-based cross-sectional study was conducted in rural parts of North Gondar Zone from April to June, 2016. Water samples from water storage at household level were taken using standardized water sampling techniques to determine the level of faecal contamination. Face-to-face interview using structured questionnaires and checklist were used to identify the associated factors. A total of 736 households participated in this study. The prevalence of positive faecal coliform in the households is found to be 72.6% (95%C.I; 69.4–75.8). In multivariate analysis; occupational status [AOR; 0.35...
High enteric bacterial contamination of drinking water in Jigjiga city, Eastern Ethiopia
Background: The high prevalence of diarrheal disease among children and infants can be traced due to the use of unsafe water and unhygienic practices. The overall concept adopted for microbiological quality is that no water intended for human consumption shall contain Escherichia coli per 100 ml sample. Objective: The aim of this study was to assess household water handling and hygienic practices and to determine bacteriological quality of drinking water from different sources in Jigjiga city. Methods: A cross-sectional study was conducted to assess bacteriological quality of drinking water in Jigjiga city from May-August, 2013. Both simple random and convenient sampling techniques were applied to select 238 households to assess water handling and hygienic practices, and 125 water samples to assess bacteriological quality of drinking water respectively. The water samples were collected from household water container, pipeline, water reservoir, 'Beyollie', and main sources. Easily isolated bacteria called coliforms were used as indicator organisms of human and other animals' fecal contamination status of drinking water. Data were summarized using descriptive and analytical statistics. Chi-square (χ2) and logistic regression tests were used and p<0.05 was considered as cut off value for statistical significance. Results: Overall, 71.2%(n=89) of water samples were contaminated by one or more bacterial species of E.coli, Shigella Sp, Salmonella Sp, and Vibrio sp. Particularly, 65(52%), 10(8%), 9(7.2%), and 8(6.4%) were contaminated by E.coli, Shigella sp, Salmonella sp, and Vibrio sp, respectively. On the other hand, 20% of the households and pipeline water samples had a fecal coliform count of 150 and above. Placement of water drinking utensils had a statistically significant association with illiterate education (p=0.01, AOR=5.47, 95% CI: (1.31, 22.78)) and male household head (p=0.02, AOR=2.11, 95% CI: (1.10, 4.05)). Conclusions: The majorities of drinking water sources were highly contaminated by Enterobacteriaceae. Regular bacteriological water quality control mechanisms need to be in place to ensure bacteriological safety of drinking water. [Ethiop. J. Health Dev. 2016;30(3):118-128]

Background Biological deterioration of drinking water is the major cause of waterborne disease globally. However, there is a paucity of information on identifying the point where deterioration of the bacteriological quality of drinking water occurs (source or point of use) and associated factors among households in developing countries, especially in Ethiopia. Method A community based cross-sectional study design was conducted among 425 households in Eastern Ethiopia. Households with at least one child under-five years of age were included in the study. A total of 448 Water samples (425 from households and 23 from water sources) were collected and analyzed by the membrane filtration method to identify Thermotolerant coliform. Binary logistic regression was performed to assess the association between each independent and dependent variable. Adjusted Odd Ratios along with 95% Confidence intervals were estimated to identify factors associated with the outcome variable. Result This study revealed that 21.7%; 95% CI (4.5%, 39.1%) of water sources and 83.3%; 95% CI (79.8%, 87.1%) of households' drinking water were contaminated by thermotolerant coliform. Drinking water samples from households with poor wealth index [AOR = 9.63; 95%CI (2.92, 31.69)], households with unimproved sanitation facility [AOR = 2.81; 95%CI (1.31, 6.01)], households which shares their house with animal [AOR = 3.73; 95%CI (1.66, 8.37)], households that didn't practice household water treatment [AOR = 3.42; 95%CI (1.60, 7.31)] and not washing hands before water collection [AOR = 7.04; 95%CI (2.22, 22.30)] were significantly associated with deterioration of bacteriological quality of household drinking water.

In the Southern Nations, Nationalities, and Peoples' Region of Ethiopia, improved water is the main source of water for household purposes. Access to improved water closer to their homes benefits the community in many ways. It improves their health status, saves their time and energy, and improves their productivity in jobs and education they are engaged in. However, due to natural and human activities, improved water sources do not always deliver good quality of water. It can be contaminated by different pathogenic microorganisms and chemicals. The result indicated that 44.7% and 50.9% of the samples were contaminated with Escherichia coli and enterococci respectively, and from the sanitary condition survey, 57.6% of the water sources exhibited from intermediate-to very high-risk level. And the risk priority matrix identifies 95 (27.9%) samples with high risk and 54 (15.9%) of the samples with very high risk. The main risks identified at those Environ Monit Assess (2020) 192:319

Fecal contamination of drinking water is a major problem in rural communities of Ethiopia, where surface water sources like rivers, wells, and lakes are used for drinking. In spite of these problems, few data exist on the microbiological safety of water sources in these settings. Therefore, the aim of this study was to investigate the microbiological safety of drinking water from the sources and households in selected communities of Shashemane rural district, Ethiopia. A descriptive analytic study was used to examine the bacteriological quality of drinking water from sources and household containers. Data on water collection and storage practices were collected using structured questionnaires. Water samples were collected according to the WHO Guidelines for drinking water quality assessment from surface and ground water sources which are used directly for drinking purpose in the community. Water samples were examined for total coliforms and fecal coliforms using the most probable number methods. The detection of Escherichia coli, Salmonella, Shigella, and Vibrio cholerae were assessed by biochemical tests. Total coliforms were detected in higher proportion in all water source samples. Fecal coliform contamination was detected in all water sources, except in hand pipes. E. coli, Salmonella and Shigella species were detected in water samples from river and wells. Total coliforms, fecal coliforms, E. coli and Salmonella spp. were also detected in water samples from households. The bacteriological load of the sampled water from source and households was found to be higher than the maximum value set for drinking water. Therefore, enabling the community access to potable water through encouraging construction of toilets, creating proper domestic and animal waste disposal system and rendering health education and sanitation practices for the community is recommended.

The quality of drinking water is a powerful environmental determinant of health. Water becomes contaminated with faecal material due to inadequate protection of the source, unhygienic practices of the community at the source, and poor household handling practices. The objective of this study was to assess the level of bacteriological contamination of drinking water supply from protected water sources to point of use and water handling practices among beneficiary households of Boloso Sore woreda, Wolaita zone, Ethiopia. A cross-sectional survey and bacteriological analysis of water were conducted in January 2019. The study included 545 households for water handling practices, and 75 samples from stored water from households and eighteen water sources were included for faecal coliform test. Data were analyzed using SPSS v21.0. Descriptive and logistic regression statistical models were used. Sixty percent of shallow wells, 60% of protected hand-dug wells, and 25% of protected on-spot ...

Article Information In Ethiopia, access to improved water supply and sanitation was estimated at 38% and 12% respectively. Three-forth of the health problems of children in Ethiopia are communicable diseases due to polluted water and improper water handling practices. Thus, this study was conducted to assess the bacteriological quality of drinking water sources in Dire Dawa Surrounding area. The study was conducted from February 2011 to May 2011. A total of 90 water samples from different water sources (-protected and unprotected well; protected and unprotected spring; and tap water) and bacteriological water quality parameters were analyzed using the membrane filtration method. Water analysis demonstrated that all water sources in the study areas were contaminated with total coliforms, fecal coliform and parasites. The average counts of TC were in the range of 1.5-133.05CFU/100ml whereas the average counts of FC were found to be 0.34-54CFU/100ml. In all samples, the TC, FC was above the recommended limit of WHOM for drinking water quality (1-10CFU/100ml for TC, 0CFU/100ml for FC. The fact that, about 83.34% of the water sample was positive for indicator bacteria shown that the three selected PA had risk of contamination in the three selected PAs had high risk of microbiological water quality parameters. High concentration of microbiological indicators in all water sources of this study area may demonstrated the presence of pathogenic organisms which constitute a threat to anyone consuming or in contact with these waters. This is due to lack of good water treatment, improper water handling practices and lack of the protection of the water sources. Consequently, protection of water sources accompanied by sanitation and hygiene promotion programs can improve the water quality of rural water sources, where disinfection is not feasible.

Background: Accesses to safe water is a universal need however, many of the world's population lack access to adequate and safe water. Consumption of water contaminated causes health risk to the public and the situation is serous in rural areas. Objectives: To assess the bacteriological and physico-chemical quality of drinking water sources in a rural community of Ethiopia. Methods: Water samples were collected from tap, open springs, open dug wells and protected springs for bacteriological analysis of total coliforms and thermotolerant coliforms. The turbidity, pH and temperature were measured immediately after collection. Results: Most drinking water sources were found to have coliform counts above the recommended national and international guidelines and had high sanitary risk scores. There was a statistically significant difference among water sources with respect to TC and TTC (p < 0.05) and there was a statistically significant positive correlation between coliform counts and sanitary risk scores (p < 0.01). Most water sources didn't satisfy the turbidity values recommended by WHO. Conclusion: The water sources were heavily contaminated which suggested poor protection and sanitation practice in the water sources. Source protection strategies as well as monitoring are recommend for this community.

Background In many nations, the deterioration of drinking water quality is a major problem that may be caused by a variety of interrelated biological, physical, and chemical causes. Human feces, animal waste, and e uent farming activities are the main pollutants of water supplies. Even if the source is clean, the process of collecting, transporting, storing, and drawing water in the home can all lead to faecal contamination. In addition, without improved water storage and sanitation, a better water supply doesn't always result in full health bene ts. Because of this, it's important to have regular quality control procedures. This study is aimed to assess the level of physioco-chemical and bacteriological quality of hosehold drinking water and its contributing factors in ood-prone settlements of South Gondar Zone, Ethiopia. Methods In villages in the South Gondar Zone that are prone to ooding, a community-based cross-sectional study was conducted from January to March 2021. Using standardized water sampling methods, samples of household water were gathered from each residence. Data on socioeconomic conditions and behavioral patterns were gathered through in-person interviews with structured questionnaires. Logistic regression models were used for both univariate and multivariate studies. Results The survey included a total of 675 households. The South Gondar Zone's settlements that are prone to ooding had a prevalence of 62.2 percent (n = 417) with [95% CI (53-60)] positive fecal coliform in household water samples. Family size [AOR = 2.205, 95% CI (1.375-3.536), latrine presence [AOR = 3.449, 95% CI (1.349-8.823)], and utilizing a separate container to draw water from its storage [AOR = 0.454, 95% CI (0.249-0.827)] are variables identi ed as predictors for fecal coliform contamination of household water. Conclusion In this study, there was a high proportion of fecal contamination in drinking water. The presence of fecal coliforms in household drinking water was found to be signi cantly related to family size, the availability of a toilet, and the usage of a separate can to draw water from its storage.
