drinking water

The provision of quality drinking water is one of the most important conditions for public health, especially in urban areas. Like many other settlements, the city of Mykolaiv faces problems with the quality of water supplied to consumers. This study evaluated some bacteriological parameters of drinking water supplied from different sources in the city and conducted a comparative analysis of the effectiveness of using plant coagulants for disinfection. Water samples were collected from underground sources, artesian wells, the municipal water supply network, and the Bug Estuary.

The purpose of the study was to assess the state of ecological development of rural rural areas of the amalgamated territorial communities of Zhytomyr district based on drinking water quality indicators of non-centralised water supply sources to ensure their sustainable development. It was found that the average pH value was within the current standard, which indicates an excellent environmental condition for this indicator. The average content of nitrates in drinking water, which in all the studied communities exceeded the standard by 1.4 to 3.5 times, was assessed at only one point.

Water is the most crucial factor for all living organisms, so it is essential to protect it. And water quality monitoring is one of the first steps required in the rational development and management of water resources. Smart systems used for real-time quality control and power consumption are rapidly developing. Their implementation in water quality assurance systems is essential and actual.

One of the main problems of rural residential areas is to provide the local population with quality drinking water, which is a major factor influencing their health. To solve this problem, it is necessary to implement effective measures not only at the state level but also at the regional and local levels. The main purpose of decentralization of power is to transfer the power and appropriate financial resources to the lowest levels of local self-government, which makes it possible for created amalgamated communities to use these resources to solve the priority issues.

The concentration of total iron is one of the main physicochemical indicators of the safety and quality of tap water. The standard amount of the concentration of common iron in tap water is not more than 0.2 mg/dm3. In some cases, due to specific natural conditions and technology for drinking water preparation/treatment, this number may be increased to 1.0 mg/dm3. Excess iron concentration in the water adversely affects the skin, blood composition, etc. Prolonged consumption of water with high iron concentration leads to liver disease, causes allergic reactions, etc.

Monitoring findings regarding fluorine concentration in drinking water of Toporiv Village in Busk District of Lviv Region are analyzed. Reasons for biogeochemical endemic of hypoplasia and fluorosis in the local population are found. The quality of drinking water has been investigated by means of biotesting using flax and lupine seeds.

The problem of drinking water preparation with specified quantitative and qualitative composition is very acute today in various countries including Ukraine. The consequences of using the method of reverse osmosis at tap water purification using the equipment with the membrane element Filmtec XLE 440 (8"), produced by DOW Chemical (USA), have been reviewed. Positive characteristics as well as economical and technological shortcomings of reverse osmosis equipment have been proved.
