Water is one of the main factors for the existence of living organisms on planet Earth. Man himself composed of nearly 85% water. Therefore, it is important to study all drinking sources to determine their element content. The demand for water worldwide is primarily for domestic, industrial and agricultural use, so it is important that this water has certain characteristics (under the normative base of the WHO) and therefore suitable for drinking, watering, etc.
Most of the water resources are located underground in the form of groundwater (99%). Their regional distribution varies and depends mainly on climatic conditions, as well as, on the geology of the underground surface. A large amount of groundwater is recovered during the hydrological cycle by the penetration of precipitation. Detailed knowledge of groundwater resources allows their sustainable use. Important factors for achieving this goal are the regional distribution of resources, the hydrogeological characteristics of the aquifer, as well as the regional and temporal variations of water quality. Various studies such as hydrogeological surveys, geophysical surveys of the earth’s surface, radiochemical analyzes and others are used to assess these resources.

About Water and its benefits
Water is a natural source of energy for our body. All life processes in the human body are related to it. Legends are passed on about water as a source of eternal health and a cure for the most terrible diseases in different parts of the world. Much of the useful properties are due to the water itself and its temperature. Mineral water with a temperature of 37 to 42 ° C blocks the pain receptors in the human body, which is the basis for relieving problems in the muscles and joints. Mineral water is also one of the main means of relieving stress. According to a number of studies, mineral water procedures relax the mind, help a person to forget about negative thoughts, relax qualitatively and fully, as well as to recharge with energy for the challenges in everyday life. Studies show that even mild dehydration can disrupt many aspects of brain activity. Water is also widely used in agriculture, industry, the economy and transport. On the other hand, in recent years it has also been said that it is a major natural resource that is depleting. In this regard, it is the subject of ongoing research aimed at studying all its beneficial properties. The Institute for Nuclear Research and Nuclear Energy at the Bulgarian Academy of Sciences has also worked over the years and is currently working on this topic. A number of scientific papers have been published, and there are also defended doctoral students and graduates. After the significant public interest in terms of the purity of drinking water, as well as mineral water, it has become traditional to study various water sources for the presence of radioactive elements.
