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.

Ensuring safe water supply for communities across the United States is a growing challenge in the face of aging infrastructure, impaired source water, and strained community finances. In the aftermath of the Flint lead crisis, there is an urgent need to assess the current state of US drinking water. However, no nationwide assessment has yet been conducted on trends in drinking water quality violations across several decades. Efforts to reduce violations are of national concern given that, in 2015, nearly 21 million people relied on community water systems that violated health-based quality standards. In this paper, we evaluate spatial and temporal patterns in health-related violations of the Safe Drinking Water Act using a panel dataset of 17,900 community water systems over the period 1982–2015. We also identify vulnerability factors of communities and water systems through probit regression. Increasing time trends and violation hot spots are detected in several states, particularly in the Southwest region. Repeat violations are prevalent in locations of violation hot spots, indicating that water systems in these regions struggle with recurring issues. In terms of vulnerability factors, we find that violation incidence in rural areas is substantially higher than in urbanized areas. Meanwhile, private ownership and purchased water source are associated with compliance. These findings indicate the types of underperforming systems that might benefit from assistance in achieving consistent compliance. We discuss why certain violations might be clustered in some regions and strategies for improving national drinking water quality.

The article is devoted to the scientific and theoretical analysis of the current state of legal provision of drinking water quality in rural areas. It was stated that in recent years there has been a steady trend of deteriorating quality of water used for drinking in rural areas, including due to increasing levels of nitrate pollution. Proposals have been made for: further implementation of Council Directive 98/83 / EU on the quality of water intended for human consumption and Council Directive 91/676/ EEC on the protection of waters against pollution caused by nitrates from agricultural sources in national legislation; elimination of substantive inconsistencies between State sanitary norms and rules 2.2.4-171-10 “Hygienic requirements for drinking water intended for human consumption” and National Standards of Ukraine 7525: 2014 “Drinking water. Requirements and methods of quality control “in terms of drinking water quality indicators; inclusion in the subjects of state water monitoring of the central executive body that implements the state policy in the field of health care (regarding the monitoring of drinking water); development of the Procedure for state monitoring of nitrate content in surface and groundwater as a component of state water monitoring; forecasting at the level of the National Target Program “Drinking Water of Ukraine” for 2021-2025 “development and operation of a single state information resource - Interactive map of drinking water quality in Ukraine.

Background: The quality of water for human consumption is an objective of fundamental importance for the defense of public health. Since the management of networks involves many problems of control and efficiency of distribution, the Water Safety Plan (WSP) was introduced to address these growing problems. Methods: WSP was applied to three companies in which the water resource assumes central importance: five water kiosks, a third-range vegetable processing company, and a residence and care institution. In drafting the plan, the terms and procedures designed and tested for the management of urban distribution systems were applied to safeguard the resource over time. Results: The case studies demonstrated the reliability of the application of the model even to small drinking-water systems, even though it involved a greater effort in analyzing the incoming water, the local intended use, and the possibilities for managing the containment of the dangers to which it is exposed. This approach demonstrates concrete effectiveness in identifying and mitigating the dangers of altering the quality of water. Conclusions: Thanks to the WSP applied to small drinking-water systems, we can move from management that is focused mainly on verifying the conformity of the finished product to the creation of a global risk assessment and management system that covers the entire water supply chain.

Aim. Study of the influence of drinking water quality on the ecologically-dependent morbidity of the population of the Republic of Dagestan.Material and Methods. Methods of current and retrospective analysis of regional health indicators and methods of mathematical-statistical and medical-geographical analysis were used. Statistical processing of the results was carried out using the STATISTICA and Excel software packages. When carrying out laboratory studies on the quality of drinking water, we used a Lumex atomic absorption spectrometer "MGA-915MD".Results. Numerous hygiene studies indicate the direct impact of unsatisfactory drinking water quality on the health of a population. The relationship between sanitary and chemical indicators and the incidence rate for a number of nosological forms has been proven. It is generally accepted that human health is influenced by lifestyle factors (working, living and relaxation conditions), heredity and the ecological condition of the area of residence, including the quality of drinking water. Although it is not possible to differentiate the share of the negative effect caused by the consumption of poor quality drinking water but the incidence of certain nosological forms (cancer of the esophagus, gastrointestinal tract and kidney diseases) in the those regions of the Republic of Dagestan under consideration correlates with the characteristics of drinking water.Conclusion. The problem of pollution of water supply sources for the population in the dynamics of the long-term remains a priority concern. The quality and safety of drinking water are decreasing, which cannot but have a negative impact on public health. Correlation linkages between indicators of drinking water quality and oncological morbidity of the population were also established in indicators below the maximum permissible concentrations, which corresponds to a typical logistic model of causal relationships and serves as evidence of the high dependence of health disorders on chemical contamination of water supply sources.

Clean, fresh, and safe drinking water is essential to human health and well-being. Occasionally, chemical pollutants taint surface water quality used for consumption. Microcystins (MCs) are toxic heptapeptides produced by freshwater cyanobacteria. These secondary metabolites can reach hazardous concentrations, impairing surface drinking water supplies. Inconsistent screening of MCs is not uncommon in Florida waters as no provisional guidance value is established to protect public health. The occurrence of MCs in Lake Manatee and Lake Washington was monitored over the potential peak algae bloom season (June-August). An indirect competitive enzyme-linked immunosorbent assay (icELISA) quantified total MCs in two drinking water systems. Varied concentrations occurred between June and July, whereas concentrations peaked in August. Overall, MC prevalence was higher in Lake Manatee than Lake Washington. Colorimetric assays measured phosphate and nitrite in environmental water samples. Phosphate and nitrite concentrations strongly correlated with total MCs (p < 0.01). The results indicate the intrinsic nature of environmental MCs in surface drinking water supplies and the need to examine hepatotoxin dynamics to preserve drinking water quality in community served areas.

In the past two decade, the Chinese government has paid a huge effort to solve the problem of drinking water in remote rural. As an alterative success case, rainwater harvesting and utility has been the most efficient way to supplying fresh water in rural areas of the Loess Plateau, a typical water resources serious shortage area in China. Focused on improving the quality of the rural village cistern water, study about the characteristics of ion release from building materials during runoff process with five representative materials used for rainwater collection: concrete, red brick, grey tile, red tile and soil was conducted. The ion releasing process and following effect on cistern water quality index, such as hardness, pH, conductivity, has been analyzed. Results revealed that the most release strength of different materials was arriving at 30s following startup. Furthermore, the test of effects of rain acidity on ion release procession showed that the total ion release increased with storm water pH declining, however, the release strength was irrelevance with runoff’s pH. Based on research results, a detailed suggestion was provided to renovate intake construction of cistern for improving the drinking water quality in remote rural areas of Weibei Semi-arid District.
