Objectives. The objective of the study on bottled drinking water consumption in Eastern European countries is to provide insight into the current state of bottled water on the market, consumer behaviour and preferences, and the potential impact on health and the environment, with the aim of informing decision-making and policy development. Material and methods. A wide area of articles from PubMed, NCBI, HINARI, Google Scholar databases over the last ten years describing tap drinking water, bottled drinking water, the potential for distribution of bottled drinking water to the population in Eastern European Countries, and the impact on the health were explored. Common used keywords: bottled water, water quality, and accessibility to water sources. Results. The preference for bottled drinking water versus tap water can vary depending on a variety of factors, such as geographic location, access to safe tap water, personal preferences, and cultural norms. In some parts of the world, such as Western Europe, tap water is generally considered safe and used as the primary source of drinking water by most people. However, in other regions where access to safe drinking water is limited, such as some parts of Africa and Asia, bottled water may be the preferred option. In general, bottled water is often considered to be a convenient and safe alternative to tap water. However, bottled water can also be expensive, and the production and transportation of plastic bottles can have negative environmental impacts. Bottled water consumption in Eastern European countries varies depending on the country and the level of economic development. According to a 2019 report by Zenith Global, the total bottled water consumption in the region was around 25 billion litres, with Russia being the largest market, followed by Poland, Ukraine, and Romania. The report also highlighted that the per capita consumption of bottled water in Eastern Europe is lower than in Western Europe, with the exception of a few countries, such as Poland, where the consumption is relatively high. According to a report by Zenith Global, the entire amount of bottled water consumed in Moldova in 2019 was estimated to be over 215 million litres, representing 61 litres per person. The low consumption is partly due to tap water being generally safe to drink in most of the region and also to the high cost of bottled water compared to tap water. Conclusions. The decision to consume bottled water or not is a personal choice, and it's necessary to consider the potential benefits and drawbacks of each option before making a decision. In many cases, a combination of both bottled and tap water may be the best option for meeting individual hydration needs while minimizing environmental impact.
