As sources of water supply in the Republic of Moldova underground waters constitute 15,2% (bore holes, springs and wells). The present work includes water quality investigations and aims to reveal local sources in river Nistru hydrographic basin (Rezina district) for drinking water provision in villages. Chemical composition of investigated spring’s water shows that in Rezina district 19% of springs are polluted with nitrogen compounds. Water of only 9% of springs is in conformity with the standard for drinking water. Water from 102 springs meets the requirements of irrigation that doesn’t present the risk of soil salinization (K > 18) – 1 383 L/min.

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.

The Impact

This peer-reviewed paper examines the risks and responsibilities of water providers and the process resource companies should undertake to document how they will deliver a safe and secure water supply to their employees and contractors, and the communities in which they operate, thereby reducing the risks of water quality incidents and managing the impact to the organisation should an incident occur. Water quality incidents can have major impacts to human health and the brand perception of the resource company supplying the water, and can potentially shutdown resource abstraction. Resource companies have a duty of care to provide a secure and safe drinking water supply. This is reinforced by state health departments directing resource organisations to comply with the Australian Drinking Water Guidelines (ADWG), which were updated in 2011 (National Health and Medical Research Council, 2011). Organisations in the CSG industry experience an additional challenge—managing water by-product from gas extraction. There are drivers for the beneficial use of this water—including irrigation, aquifer recharge and municipal supply—resulting in changes to legislation in Queensland (DERM, 2010) that require a process similar to ADWG recommendations, where beneficial use or disposal may impact potable supplies. The ADWG provides clear guidance to potable water providers—whether they are supplying a few consumers or major towns requiring a Drinking Water Quality Management System (DWQM System). This guidance includes documenting a clear process to securing a clean water source, making the water safe to consume and proving it is safe. Developing a DWQM System enables resource companies to understand issues in supplying drinking water through regular review and improvement, while minimising and managing the health risks to consumers.

The problems of drinking water quality have been considered in some settlements of the Turkivskiy district of Lviv region, in particular concerning the content of Nitrogen compounds. 20 sources of decentralized water supply were investigated. It was found that the main hydrochemical indicators of water samples mainly met the requirements for the degree of contamination of hygienic classification of water bodies. At the same time, analyzing the samples for the presence of nitrogen compounds, it was found that in the tested samples: the content of nitrate ions fluctuated within 0,02 - 016 mg/dm3 (average annual values did not exceed the permissible value); the content of ammonium ions is in the range of 0.5-2.8 mg/dm3, which did not significantly exceed the maximum permissible value. At the time, analysis for NO3- showed an excess of acceptable values in almost all samples by 1.3 у 4.2 times. It was found that the amount of nitrates decreased with the transition from the alluvial aquifers to the indigenous ones, where the average content was 108.9 mg/dm3 and 86.8 mg/dm3, respectively. This is probably due to better protection of the bedrock from surface contamination, greater capacity of the corresponding aquifers and their deeper occurrence. According to the average value of the water pollution index for the nitrate group, the studied objects of decentralized water supply belong to the second class ‒ moderately contaminated. The correlation between the water pollution index by nitrate group and the population morbidity is calculated to be direct and sufficiently high (0.73). The most associated indicators of water quality are diseases of the circulatory system, blood and hematopoietic organs, digestive organs, endocrine and urogenital systems.

The results of the study of ecological and geochemical features and assessment of the water quality of water sources located on the territory of the Semipalatinsk test site are presented. The studied waters are diverse in chemical composition: 14 % of the samples had hydrocarbonate, 69 % – sulfate, and 17 % – chloride types of waters. On the basis of the revealed features of the elemental composition of the underground waters of the Semipalatinsk test site, decreasing series of excess of the average concentrations of elements in water in relation to the composition of waters of the zones of hypergenesis and continental salinization were constructed: U14 > Mo8 > Sr8 > V3 (hypergenesis zone), U5 > Mo3 > Sr3 > V2 (zone of continental salinization). For the groundwater of the Semipalatinsk test site, specific elements were identified, such as U, Mo, Sr and V. The water quality was assessed for the studied chemical components based on comparison with the standards of the Republic of Kazakhstan and the World Health Organization (SaNPiN No. 209, WHO 2011).

The article discusses the historical geography of the river Prut (967 km). In the ancient period it was known as the Pyretus, Porata, or Prout. The river originates on the eastern slope of Mount Hoverla (2 068 m), in the Carpathian Mountains in Ukraine. The Prut flows to the southeast, eventually joining the Danube near Giurgiuleşti, east of Galați. The Prut currently divides three countries: Romania, the Republic of Moldova and Ukraine. At present, it constitutes the border between Romania and Moldova, with a total length of 695 km. It has a hydrographic basin totaling 27 540 km2 , of which 10 990 km2 are in Romania and 7 980 km2 in Moldova. The article presents a summary description of the geographical setting and hydrographic specificity of the Prut River. The main geo-morphological characteristic features of the Prut basin are presented. The author also offers a historical overview of the main settlements situated on the river, as well as a brief analysis of the recent projects for international cooperation centered on the Prut as an important waterway of the region. Finally, the author emphasizes the role of the Prut as a border river, looking at both the pragmatic and symbolic dimensions of its significance for Romanian history.

Introduction. Boron is a trace mineral that is supposed to be essential for human health. Organic plant based boron compounds are highly bioavailable for humans and can positively influence minerals such as calcium, phosphorus, magnesium and act in synergy with vitamin D, which are beneficial for osteoarticular health. Material and methods. We made an analysis of 126 bibliographic sources and mapped the Republic of Moldova to the content of boron in deep water and to the adults’ prevalence of rheumatoid arthritis and inflammatory polyarthropathy. Results. Boron is important for osteogenesis and its deficiency can lead to impaired growth and abnormal bones development. It supports bone health in postmenopausal women by reducing urinary loss of the minerals such as calcium, magnesium and phosphorus, which are essential for bone building. In countries where soil was depleted of boron and daily intake of this mineral was 1 mg or lower, the incidence of arthritis was between 20 and 70%. In Moldova, in the regions where boron concentration in deep drinking water were low (0.28 mg/L in well water and 0.51 mg/L in artesian well water) in Soroca in 2019, the prevalence with the rheumatoid arthritis and inflammatory polyarthropathy were high (51.6 per 10000 inhabitants) with one exception, UTA Gagauzia (35.1 per 10000 inhabitants), where we found a high boron concentration in deep drinking water (2.05 mg/L in well water and 2.2 mg/L in artesian well water) in 2015. Conclusions. Boron can affect bone metabolism. In regions where boron concentration in deep drinking water is low, the osteoarticular morbidity can be higher with the exception of UTA Gagauzia, where we suppose that dietary pattern can be a cause of these results. In the future we will study eating habits in this region and a clearer conclusion will be made.

This paper examines effects of drinking water components, namely calcium and magnesium ions on the human body as well as it lists the main diseases that occur with prolonged use of hard water. Kostarevsky water intake is described as the only source of centralized water supply of the city. The paper contains data of ecological monitoring of drinking water taken from Kostarevsky water intake in Birsk from 2015 to 2017. The authors compare drinking water in Birsk and some other cities of the Republic of Bashkortostan. The chemical composition of the water was determined by titrimetric, gravimetric, colorimetric, organoleptic, and microbiological methods of investigation. The results of the analysis show that the water given to the population of Birsk along the central water supply line is microbiologically favorable. The chemical composition of water almost in all respects meets the requirements of Sanitary Regulations and Standards 2.1.4.1074-01 Drinking water. Hygienic requirements for water quality. However, the analysis results show that the rigidity of the water exchange is beyond the permissible limit of the norm, which can adversely affect the health of the population. The results obtained during the work can be useful for further ecological monitoring of drinking water in Birsk, Republic of Bashkortostan.
