Practical use of radiation parameters of drinking water quality: guidelines of international organizations and ukrainian experience

The analysis of the documents of the authoritative international organizations and scientific works was carried out from the point of view of the development of the strategy for ensuring the radiation quality of drinking water. The radiation parameters of the quality of drinking water, the interpretation of monitoring results by screening and recommended levels, the value of the individual dose criterion, as well as algorithms for establishing the frequency of monitoring of the radiation parameters of drinking water were considered. Objective: We analyzed the documents of reputable international organizations and scientific works in terms of the development of the strategy for ensuring radiation quality of drinking water and the features of the practical application of the parameters of water radiation quality in the world and Ukraine. Methods: bibliographic, analytical. Materials: We performed the analysis of the documents of international organizations (WHO, IAEA, ICRP, UNSCEAR), as well as scientific publications on the radiation quality of drinking water in the light of the experience in measuring the content of drinking water radionuclides at the territory of Ukraine. Results: Materials of the international documents and scientific publications demonstrate that the assessment of radiation quality of drinking water requires a balanced analysis. In some cases, based on the results of only one determination of the total alpha and total beta activity, it is impossible to draw an unambiguous conclusion about the suitability or unsuitability of drinking water for consumption. Taking into account the geological heterogeneity of the territory of Ukraine, in order to obtain sufficient data on the radioactivity of groundwater, it is necessary to conduct extensive screening studies of the radiation quality of water in the regions of the country with the involvement of geological and monitoring services, local authorities.

The aim of the work was to elaborate and evaluate the water quality of water reservoir Vranov nad Dyjí. Fresh water was sampled in five different locations of the reservoir (three important tributaries, dam and water captation locality). Ten, the most essential water quality indicators were selected. From the point of view of water quality indicators complexity the most integrated samples were taken in the water captation locality (period 1984 – 2002). At other locations, there were missing dates from the eightieth, but their volume was sufficient for statistical processing.Correlation analyses for the individual locations and dimensions were done as so as determination coefficients for all localities during the time period of 1994 – 2002. The results demonstrate very good allocation of the water captation from the point of view of the water flow.Multiples and factor analysis was done for the period of 1984 – 2002 in the locality Jelení zátoka where the object of water captation is situated. The results of the analysis are nine factors, which influence the water quality of the reservoir. From the point of view of the importance three factors were interpreted.The analyses and results are part of my Ph.D. thesis. The results will be used for other evaluations of the water quality in the reservoir and tributaries, for activities in the catchment’s area and for proposal processing other zones of second level of protected areas.

In Senegal, the majority of the regions are not served by the drinking water supply networks. The phenomenon is more pronounced in rural areas, particularly in Sinthiou Maléme commune. For example, communities living in these areas often use well water and borehole. This work has been undertaken to evaluate the physicochemical quality of the water resources consumed by these populations. A total of 24 water samples were taken from the single borehole and 02 publics wells, let be 8 samples per source of water. To assess the quality of these different sources, the physical parameters (electrical conductivity, pH, total dissolved solids and hardness) and chemical parameters (F-, SO42-, PO43-, Fe and NO2-) were analyzed by the photometric method. The results obtained show that, from the physical point of view, drilling water is highly mineralized, slightly hard and has a basic tendency, unlike wells. Chemical analysis shows that well waters are heavily loaded with phosphate ions and nitrites. Based on the parameters analyzed, the quality of the drilling water is chemically acceptable. Studies on the elements of metallic traces will be envisaged to better assess the quality of this drinking water. Au Sénégal, la majeure partie des régions n’est pas desservie par les réseaux d'adduction d’eau potable. Le phénomène est plus accentué en milieu rural notamment dans la commune de Sinthiou Maléme. Ainsi, les communautés qui vivent dans ces zones ont souvent recours à l'eau des puits et des forages. Ce présent travail a été entrepris en vue d’évaluer la qualité physico-chimique des ressources en eaux consommées par ces populations. Au total 24 échantillons d’eaux ont été prélevés de l’unique forage et de 02 puits publics, soit 8 prélèvements par sources d’eaux. Pour apprécier la qualité de ces différentes sources, les paramètres physiques (conductivité électrique, pH, totale des solides dissous et dureté) et chimiques (F-, SO42-, PO43-, Fe and NO2-) ont été analysés par la méthode photométrique. Les résultats obtenus montrent que, du point de vue physique, les eaux de forage sont fortement minéralisées, légèrement dures et présentent une tendance basique contrairement à celles des puits. L’analyse chimique montre que les eaux de puits sont fortement chargées en ions phosphates et nitrites. Sur la base des paramètres analysés, la qualité des eaux de forage est chimiquement acceptable. Des études sur les éléments des traces métalliques seront envisagées pour mieux apprécier la qualité de ces eaux de consommation.

From a phenomenological perspective, the reflective quality of water has a visually dramatic impact, especially when combined with the light of celestial phenomena. However, the possible presence of water as a means for reflecting the sky is often undervalued when interpreting archaeoastronomical sites. From artificial water spaces, such as ditches, huacas and wells to natural ones such as rivers, lakes and puddles, water spaces add a layer of interacting reflections to landscapes. In the cosmological understanding of skyscapes and waterscapes, a cross-cultural metaphorical association between water spaces and the underworld is often revealed. In this research, water-skyscapes are explored through the practice of auto-ethnography and reflexive phenomenology. The mirroring of the sky in water opens up themes such as the continuity, delimitation and manipulation of sky phenomena on land: water spaces act as a continuation of the sky on earth; depending on water spaces’ spatial extension, selected celestial phenomena can be periodically reflected within architectures, so as to make the heavenly dimension easily accessible and a possible object of manipulation. Water-skyscapes appear as specular worlds, where water spaces are assumed to be doorways to the inner reality of the unconscious. The fluid properties of water have the visual effect of dissipating borders, of merging shapes, and, therefore, of dissolving identities; in the inner landscape, this process may represent symbolic death experiences and rituals of initiation, where the annihilation of the individual allows the creative process of a new life cycle. These contextually generalisable results aim to inspire new perspectives on sky-and-water related case studies and give value to the practice of reflexive phenomenology as crucial method of research.

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.

Introduction: Safe water is a precondition for health and development and is a basic human right, yet it is still denied to hundreds of millions of people throughout the developing world. Water-related diseases caused by insufficient safe water supplies, coupled with poor sanitation and hygiene, cause 3.4 million deaths a year, mostly in children. Methodology: The present study was conducted on 1,317 drinking water samples from various water sources in Amritsar district in northern India. All the samples were analyzed to assess bacteriological quality of water for presumptive coliform count by the multiple tube test. Results: A total of 42.9% (565/1,317) samples from various sources were found to be unfit for human consumption. Of the total 565 unsatisfactory samples, 253 were from submersible pumps, 197 were from taps of piped supply (domestic/public), 79 were from hand pumps, and 36 were from various other sources A significantly high level of contamination was observed in samples collected from submersible pumps (47.6%) and water tanks (47.3%), as these sources of water are more exposed and liable to contamination. Conclusions: Despite continuous efforts by the government, civil society, and the international community, over a billion people still do not have access to improved water resources. Bacteriological assessment of all sources of drinking should be planned and conducted on regular basis to prevent waterborne dissemination of diseases.

Ntroduction. The assessment of water quality and safety of centralized water supply systems in the Primorsky Krai was carried out in order to assess hygiene levels of public health risks associated with drinking water from the distribution network. Material and methods. The data of laboratory studies on sanitary and chemical parameters in drinking water of the distribution network of the Primorsky region were used. Hygienic assessment of drinking water was carried out according to regulatory requirements, the effect of summation of biological effect was calculated. The work used methodological recommendations for calculating the index of chemical water pollution and the utility coefficient, as well as a guide for assessing the health risks of the population when exposed to chemicals of a non-carcinogenic and carcinogenic nature. Non-carcinogenic and carcinogenic risks were calculated for all potable water of centralized water supply based on the average daily intake dose and the reference dose of chemicals supplied with drinking water. The risk profile for carcinogenic and non-carcinogenic effects was achieved by comparing exposure levels with reference concentrations (safe) for human health. The risk profile for the combined effects of chemical compounds is based on the calculation of the hazard index (HI). A study on carcinogenic risk was carried out for substances that are identified as carcinogens according to the classification of an international agency for the study of cancer. For the analysis and statistical processing of information, the program "MS Excel" was used. Results. An assessment of the sanitary and epidemiological safety of centralized systems of domestic and drinking water supply in the region showed that the highest contribution to poor health is made by the content of arsenic, nitrates, iron, silicon, and petroleum products in drinking water. According to the values of hazard indices, the skin and mucous membranes, the central nervous system, the immune system, the endocrine system, the circulatory and digestive organs are exposed to adverse effects from chemicals in drinking water. The individual carcinogenic risk ranges from negligibly small to the upper limit of acceptable carcinogenic risk. Assessment of the potable water value indicator revealed a deficit situation in calcium, sodium, fluorine and general mineralization of water. The risk assessment for arsenic, tetrachlorethylene, and chloroform, which have carcinogenic properties and are the most important pollutants of drinking water, has shown that the individual risk levels for these substances are within the first and second ranges, which corresponds to the allowable and maximum allowable risk. Discussion. Arsenic concentration in adults was found to be not detected with risks greater than one, while for children, the non-carcinogenic risk from arsenic exceeded the level of safe exposure (HQ> 1), because children are more susceptible to toxic substances due to their relatively large volume of respiration and the rate of gastrointestinal absorption (due to greater permeability of the intestinal epithelium), and also due to the immature system of detoxification enzymes and a relatively lower rate of excretion of toxic chemicals. According to the level of non-carcinogenic risk for children, nitrates follow arsenic. Nitrates have a hypoxic effect, increasing the concentration of the irreversible form of hemoglobin - methemoglobin. The toxicity of nitrates is related to their transformation into the human body into nitrosamines. As a result, the child's organism responds more sharply than in adults to the presence of chemicals in the water. The general mineralization of drinking water is one of the integral index of the quality of drinking water. Calcium and magnesium deficiency can be an independent risk factor for the development of various diseases and manifest pathologies of the cardiovascular system: coronary heart disease, hypertensive disease, myocardial infarction, etc. The tap water is known to be is not overloaded with carbonates, since they can lead to spoilage of water pipes. Therefore, to enrich the water with calcium and magnesium, the technology of creating bottled water uses mineral additives, which means that such water can become an additional source of minerals. Conclusion. Sanitary and hygienic assessment of centralized systems of domestic and drinking water supply in the Primorsky Territory has shown that the quality of drinking water depends on the concentration of arsenic, nitrates, iron, silicon and petroleum products. It should be noted that with the daily use of water from the distribution network throughout life, the likelihood of developing harmful effects on the health of adults and children is insignificant.

This document proposes a methodology for assessing the quality of water distribution service in the context of intermittent supply, based on a comparison of joint results from literature reviews and feedback from drinking water operators who had managed these networks, with standards for defining the quality of drinking water service. The paper begins by reviewing and proposing an analysis of the definition and characterization of intermittent water supply (IWS), highlighting some important findings. The diversity of approaches used to address the issue and the difficulty of defining a precise and detailed history of water supply in the affected systems broadens the spectrum of intermittency characterization and the problems it raises. The underlined results are then used to structure an evaluation framework for the water service and to develop improvement paths defined in the intermittent networks. The resulting framework highlights the means available to water stakeholders to assess their operational and management performance in achieving the improvement objectives defined by the environmental and socio-economic contexts in which the network operates. Practical examples of intermittent system management are collected from water system operators and presented for illustration purposes (Jeddah, Algiers, Port-au-Prince, Amman, Cartagena, Barranquilla, Mexico, Cancun, Saltillo, Mumbai, Delhi, Coimbatore …).
