Lack of access to safe and adequate domestic water supplies contributes to poverty levels through the economic costs of poor health and the high proportion of household expenditure on safe water supplies. Gwallameji, a community on the outskirts of Bauchi town has no access to municipal water supply from Bauchi town, groundwater water, mainly hand dug wells are used as domestic water sources. The quality of water available from these hand dug wells  in the community were determined by the physical, chemical and biological parameters of the water samples collected from domestic water points in the community. The results from the water samples were compared with World Health Organization (WHO) Standards for Drinking Water. High levels of Nitrate and Chromium above recommended levels from the standard were found in all water samples. Concentrations of Calcium highest value of 213mg/l and Magnesium a highest value of 22.02 mg/l at levels higher than recommended levels for drinking water were also obtained in all samples. It was recommended that restrictions on farming activities with use of fertilizers and location of latrines around domestic water sources should be enforced. Hand dug wells should be at a distance of at least 30m from soak away pits and pit latrines. Well lining and cover should be provided for all hand dug wells to reduce contamination of water from these sources. Increased and continued environmental interventions through public health education by community based health workers, awareness and sensitization campaigns should be carried out for improved household and community sanitation in the area.

Drinking water in Ghana is estimated at 79%, but this only represents the proportion of the population with access to improved drinking water sources without regard to the quality of water consumed. This study investigated the quality of household drinking water sources in the Oforikrom municipality where potable water requirements are on the rise due to an ever-increasing population. Both quantitative and qualitative methods were employed in this study. One Hundred households were randomly selected and interviewed on the available options for drinking water and household water treatment and safe storage. A total of 52 points of collection (POC) and 97 points of use (POU) water samples from households were collected for physicochemical and microbial water quality analysis. Amongst the available drinking water options, sachet water (46%) was mostly consumed by households. Water quality analysis revealed that the physicochemical parameters of all sampled drinking water sources were within the Ghana Standards Authority (GSA) recommended values expected for pH (ranging from 4.50 to 7.50). For the drinking water sources, bottled (100%, n = 2) and sachet water (91%, n = 41) showed relatively good microbial water quality. Generally, POC water samples showed an improved microbial water quality in comparison to POU water samples. About 38% ( n = 8) of the households practicing water quality management, were still exposed to unsafe drinking water sources. Households should practice good water quality management at the domestic level to ensure access to safe drinking water. This may include the use of chlorine-based disinfectants to frequently disinfect boreholes, wells and storage facilities at homes.

Rainwater, borewater and catchment water are used for domestic water supply purposes with or without treatment in remote areas around the world. These places seldom have any facilities for routine testing of their drinking water. A simple on-site testing method is highly required in such areas. The H2S method has been tested for treated drinking water and was found to have a good correlation with the standard methods. The present study was aimed at assessing the suitability of the H2S method for testing different sources of drinking water. Since these types of water may contain H2S producing bacteria not of faecal origin the occurrence of false results in this method cannot be overruled. Therefore it was worthwhile to study whether the positive results are true positive results and what percentage of false positive and false negative results could be expected while using this test for routine analysis of water samples. Results were compared with the results using standard procedures for testing total coliforms, Escherichia coli and Salmonella spp. The present experiment analysed 121 rainwater samples, 17 borewater samples, 41 catchment water samples and 74 remote Aboriginal community water samples. Rainwater, borewater and catchment water samples gave true results of 78.5%, 82.3% and 80.5% respectively while the treated and untreated community samples gave true results of 93.7 and 84.6% respectively. It was concluded that in the developing countries where the acceptable level of total coliform is <10 MPN, the H2S method would be a good test to identify microbial contamination. In other regions, the H2S method could be used as a screening test for drinking water supplies.

Introduction: Access to sufficient and safe drinking water is essential for human health and welfare. Countries in the Pacific Region like Fiji frequently face issues with access to safe drinking water and supply problems. Fluctuations in water resource availability, often untreated water and faulty treatment facilities, pollution, lack of proper water management frameworks and most importantly lack of water monitoring resources are all factors that influence Pacific Island Countries. Apart from this, Pacific Islands and their water supplies are susceptible to climate hazards such as floods, cyclones and drought. The Western Division of Fiji Islands is highly prone to adverse climatic conditions; therefore regular monitoring of the various drinking water sources is essential to ensure safety of people. This study was conducted in the Lautoka to Nadi corridor where 25 sites were randomly selected for water analysis processing from January to February 2019.    Method: Physio-chemical analysis, such as measuring pH and turbidity as well as simple microbial analysis, was conducted on the water samples. Specific growth media was used to determine the different types of bacteria (Coliform, Escherichia coli and Salmonella enterica) present in the water samples; Lauryl Tryptose Broth, Eosin Methlylene Blue Agar, Xylose Lysine Deoxycholate was used. Turbidity was measured using a digital turbidity meter and pH value was determined employing a digital meter. Results and Discussion: From the analysis it was determined that overall the pH levels of samples (6.02-8.30) falls within the permissible limits; whereas turbidity was generally higher in untreated water sources with ranges from 3 to 8 nephelometric turbidity units. Microbial content was higher in untreated water samples. Other sources such as springs and creeks recorded the most significant number of Coliforms when compared to other sources and some samples indicated the presence of Escherichia coli and Salmonella enterica. Conclusion: From the study it can be concluded that all the water samples tested positive for bacterial contamination particularly Coliforms and it was higher in untreated water. Water from the Municipality had almost all physio-chemical and bacteria parameters within the World Health Organization limits, except for turbidity which was generally above 1NTU. However, this was not the case for untreated water which in some samples contained high levels of harmful bacteria. Monitoring needs to be carried out to better understand water quality and implement counter measures.

Abstract A second national survey was done to ascertain the levels of Cd, Co, Cr, Cu, Ni, Pb, Zn, Ca, and Mg in Canadian drinking water supplies. Raw, treated, and distributed water samples collected from 71 municipalities across Canada were analyzed both by atomic absorption spectrophotometry using the direct method and by an APDC-MIBK extraction procedure. As in the first national survey, the amounts of trace metals found in the 3 types of water samples were essentially the same. Contamination of the water supplies with these metals except Cu and Zn was minimal during treatment and distribution. For Canadian drinking water, the median and extreme values expressed as ng metal/mL water were: Cd ≤0.02 (≤0.02-0.07), Co ≤2.0 (≤2.0-6.0), Cr ≤2.0 (≤2.0-4.1), Cu ≤10 (≤10-900), Ni ≤2.0 (≤2.0-69.0), Pb ≤1.0 (≤1.0-79.7), and Zn ≤10 (≤10-750). Hardness values as mg CaCO3/L, ranged from 6.7 in St. John’s, Newfoundland, to 328.3 in Portage La Prairie, Manitoba. The median values for the Canadian drinking water supplies were well below the maximum permissible limits set by Health and Welfare Canada and the World Health Organization.

Abstract Water is an indispensable commodity for the survival of all living beings and for their well-being. The objective of this work is to evaluate the level of pollution of different drinking water sources consumed and its link with health in Pelengana commune, Mali. Samples of water were taken from various sources, namely, hand pumps, boreholes, dug wells, and shallow wells for physical, chemical, heavy metals, and bacteriological analyses, using American Public Health Association (APHA) Standard Techniques. Results revealed that the nitrate-nitrogen (NO3−N) values of the water samples from the different water sources had concentrations exceeding the United States Environmental Protection Agency's (US-EPA) regulation of 10 mg/L, as well as World Health Organization Guideline for Drinking Water Quality (WHO GDWQ) (11 mg/L). The same applies to heavy metals such as Cd, Pb, and Fe, in which, concentrations exceed their allowable limits in certain locations. Moreover, apart from water samples from some different boreholes, total coliform, and Escherichia coli have been detected in all selected water sources, which indicates fecal contamination. In all, there is a pressing need to stop the consumption of drinking water from contaminated sources and to effect appropriate treatment.

This cross-sectional study recorded WASH facilities in 21 departments of 5-HEIs and satisfaction appraisal of 630 students in total. The survey was also supplemented with quality analysis of Point of Use (PoU) drinking water. The results revealed that the overall 85.7 and 47.6% contamination of the drinking water samples were recorded due to total and thermo-tolerant coliforms, respectively. Further, physiochemical parameters were found in the permissible limits as provided by the World Health Organization (WHO) and arsenic was not detected in any of the water samples. In total 25% of the toilet facilities were found non-functional. All monitored HEIs were found having sufficient quantity of water however, 95% hand-washing stations did not supply soap/ detergent for hand-washing. Moreover, this study divulges that there is a significant relationship between WASH facilities like water quality (χ2= 7.55*; p=0.023), toilets functioning (χ2= 45.39**; p=0.002), and washing facilities (χ2= 37.29**; p=0.000) in HEIs and student’s satisfaction in HEIs. Thus, it can be concluded that the poor WASH facilities in HEIs could affect the students’ satisfaction leading to affect their performance in the studies, negatively.

High Mo concentrations have been detected in drinking water pumped from domestic water supply wells located in the Wadi Al Arab area, at the Irbid city, northern Jordan. The main objective of this study is to investigate hydrogeochemical processes responsible for the release of Mo in the groundwater resources. Usually Mo is a metallic element that is naturally present in the earth’s crust. However, the presence of Mo in groundwater is an important potential pollution issue. To achieve the objectives of the study, 34 water samples were collected from the whole catchment area of Wadi Al Arab and were analyzed using ICP-MS for total Mo and the other major cations, anions and heavy metals. The results obtained from the hydrogeochemical investigation show that the groundwater in Wadi Al Arab catchment area is susceptible to Mo contamination due to the chemical reactions of water with clay-rich underlying bedrock that consists mainly of shale and marl rocks. The concentration values measured at the tested wells vary from 46.6 μg/L to 1438.7 μg/L, with an average value of 397.6 μg/L. Therefore, about 70% of the analyzed water samples show Mo levels that exceed the permissible limit of 70 μg/L for drinking water according to World Health Organization. The results of geochemical modeling using VISUAL MINTEQ software show that the most abundant species of Mo mineral is molybdate ion (MoO42-), with a concentration of 30 μg/L, which accounts for more than 50% of the Mo species dissolved in groundwater. The possible source of the Mo in the groundwater in Wadi Al Arab catchment area is due to presence of oil shale and phosphate layers within the geological succession of the aquifer. Through the geochemical model, the saturation indices of the common Mo minerals were calculated. The calculated saturation indices showed that groundwater is under-saturated with respect to Mo mineral speciation, which emphasizes that natural equilibrium will never be reached.

Abstract Background Lack of sustainable access to clean drinking water continues to be an issue of paramount global importance, leading to millions of preventable deaths annually. Best practices for providing sustainable access to clean drinking water, however, remain unclear. Widespread installation of low-cost, in-home, point of use water filtration systems is a promising strategy. Methods We conducted a prospective, randomized, controlled trial whereby 16 villages were selected and randomly assigned to one of four treatment arms based on the installation location of Sawyer® PointONE™ filters (filter in both home and school; filter in home only; filter in school only; control group). Water samples and self-reported information on diarrhea were collected at multiple times throughout the study. Results Self-reported household prevalence of diarrhea decreased from 25.6 to 9.76% from installation to follow-up (at least 7 days, and up to 200 days post-filter installation). These declines were also observed in diarrhea with economic or educational consequences (diarrhea which led to medical treatment and/or missing school or work) with baseline prevalence of 9.64% declining to 1.57%. Decreases in diarrhea prevalence were observed across age groups. There was no evidence of a loss of efficacy of filters up to 200 days post-filter installation. Installation of filters in schools was not associated with decreases in diarrhea prevalence in school-aged children or family members. Unfiltered water samples both at schools and homes contained potential waterborne bacterial pathogens, dissolved heavy metals and metals associated with particulates. All dissolved metals were detected at levels below World Health Organization action guidelines. Conclusions This controlled trial provides strong evidence of the effectiveness of point-of-use, hollow fiber membrane filters at reducing diarrhea from bacterial sources up to 200 days post-installation when installed in homes. No statistically significant reduction in diarrhea was found when filters were installed in schools. Further research is needed in order to explore filter efficacy and utilization after 200 days post-installation. Trial registration ClinicalTrials.gov, NCT03972618. Registered 3 June 2019—retrospectively registered.

In present investigation, the bacteriological analysis and antibiotic sensitivitypattern of drinking water samples collected from different sources ofAkungba Ã¢â‚¬ÂAkoko, Nigeria was done. The antibiotics mainly considered in ourstudy for determining the sensitivity were amongst the commonly used inthis area for treatment of infectious diseases. As a result, the bacteriologicalindex, especially coliform count was observed notably high with 72 x10 1 cfu/ml for stream sample and 26.4 x 10 1 cfu/ml for borehole sample. The majorbacterial isolates identified in the water samples were Staphylococcus sp,E.coli  Ã¢â‚¬Ânegative bacteria wereobserved showing 75% and 65% resistant to Septrin and Amoxicillin respectively.Also, multiple drug resistance was observed for many antibiotics.Therefore, the presence of high amount antibiotic resistant bacteria of clinicalimportance is reported in these water sources which are usually consumedby students and members of the University community. Hence, thisstudy necessitates the need for water treatment so that epidemics of waterbornebacterial disease can be averted in this region., Klebsiella sp, Pseudomonas sp., Enterococcus sp., Bacillus cereus andothers. With regards to the antibiotic sensitivity test, all isolates showed100% resistance to Ampicillin and Cloxacillin and 85.7% resistance to Zinnacef[a cephalosporin product]. However, the gram

Abstract Njoro sub-county in Kenya suffers from constant water shortages causing the residents to rely on both improved and unimproved water sources in the area. The households in the sub-county also use different household storage containers to store drinking water in times when water is not readily available. This study was therefore undertaken to assess selective physico-chemical parameters of water used by the population for drinking purposes using standard assessment methods. A total of 372 water source samples and 162 storage container water samples were tested over a period of three months. Turbidity (0.70–273.85 NTU), iron (0.7–2.10 mg/L), fluoride (0.15–4.01 mg/L), manganese (0.01–0.37 mg/L), and nitrate (0.09–27.90 mg/L) levels in water samples were generally higher than the Kenya Bureau of Standards (KEBS) and/or the World Health Organization (WHO) water quality recommendations for safe drinkable water. The results from this study support the need for continuous monitoring and treating drinking water at the points of collection and of consumption to minimize the long-term health effects on communities consuming this water.
