Accurate assessments of drinking water quality, household hygenic practices, and the mindset of the consumers are critical for developing effective water intervention strategies. This paper presents a microbial quality assessment of 512 samples from household water storage containers and 167 samples from points of collection (POC) in remote rural communities in the hilly area of western Nepal. We found that 81% of the stored drinking water samples (mean log10 of all samples = 1.16 colony-forming units (CFU)/100 mL, standard deviation (SD) = 0.84) and 68% of the POC samples (mean log10 of all samples = 0.57 CFU/100 mL, SD = 0.86) had detectable E. coli. The quality of stored water was significantly correlated with the quality at the POC, with the majority (63%) of paired samples showing a deterioration in quality post-collection. Locally applied household water treatment (HWT) methods did not effectively improve microbial water quality. Among all household sanitary inspection questions, only the presence of livestock near the water storage container was significantly correlated with its microbial contamination. Households’ perceptions of their drinking water quality were mostly influenced by the water’s visual appearance, and these perceptions in general motivated their use of HWT. Improving water quality within the distribution network and promoting safer water handling practices are proposed to reduce the health risk due to consumption of contaminated water in this setting.

Rural areas in Morocco are characterized by specific particulars dispersal, remoteness and importance. Considering this particular context, it is necessary to adjust the analysis and treatment methods, the monitoring and sanitary inspection systems. Within this framework, a new methodology was developed with the purpose of supervising and monitoring drinking water quality in rural areas. This methodology consists basically in applying common norms for rural localities bordering existing adductions, and in the adoption of a simplified approach for non-accessible rural localities supplied by autonomous drinking water systems. The simplified approach relies essentially on sanitary inspection data and on the control of parameters that constitute a sanitary risk in the short term (bacteriological parameters). The control of residual chlorine content is so important, for it ensures a high bacteriological quality of water and can offer the opportunity for a quick reaction of the manager. These two approaches are based mainly on resource protection, water disinfection and population awareness about the good use and preservation of water quality. Indeed, in order to ensure the continuity of rural autonomous drinking water systems in terms of quantity and quality of distributed water, various management models were developed: management by means of water user associations, and by a private operator. For these different modes of management, the methodology to adopt for supervising and monitoring drinking water quality in rural areas together with the attribution of tasks and responsibilities was already established. The right of citizens to sustainable and safe water is a stimulating challenge which requires the collaboration and involvement of all acting agents in the sector.

Summary. Introduction: As the most important environmental factor having multiple effects on human vital activities and health, drinking water often becomes the subject of predicting adverse health effects. With the purpose of establishing quantitative and/or qualitative characteristics of harmful effects of drinking water chemicals for human health, an integral assessment of drinking water quality with subsequent health risk assessment is carried out. It is based on estimating the risk posed by chronic (carcinogenic and non-carcinogenic) exposures that shows probability of developing a disease. Results: Practical activities of departments and institutions of the Federal Service for Surveillance in the Sphere of Consumers Rights and Human Wellbeing (Rospotrebnadzor) on assessing health effects of environmental factors have demonstrated that, even in concentrations equaling their detection limits in quite a number of test methods, most chemical water pollutants pose unacceptable carcinogenic and non-carcinogenic risks both for the general population and occupational cohorts. Thus, the results of some laboratory methods of testing are inappropriate for an objective human health risk assessment. Conclusions: We describe criteria for selecting methods of the quantitative chemical analysis of drinking water fit for the purposes of sanitary and epidemiologic expert examination combined with a population health risk assessment. The criteria of choice have been elaborated based on the review of regulatory and method documents and results of analytical testing of drinking water quality.

Abstract In many areas of the world, rainwater has been collected and consumed by people. Our research aims to assess the use of rainwater and the impact of operation and maintenance activities of the rainwater system on drinking water quality in rural areas where there is no access to a public drinking water system. Through the questionnaire, direct visits, interviews and sampling of water at surveyed households (HHs), it was found that 100 and 98% of surveyed HHs used rainwater for drinking and cooking, respectively. Nearly, 80% of them were aware of the necessity of frequent reservoir cleaning as well as first-flush removal. Cleaning the water reservoir had a significant impact on water quality, in particular the total dissolved solids (p-value < 0.05). The use of strainers and more frequency of cleaning the catchment roofs and gutters would make the lower turbidity in water. However, the use of strainers would reduce the dissolution of oxygen in the reservoirs. A recommendation on the frequency of maintaining the rainwater harvesting systems was proposed after assessment of the operation and maintenance behaviors at surveyed HHs.
