The quality of drinking water is of paramount importance for the health and life of any person, and poor quality water can provoke a number of diseases or complications. The problem of drinking water quality is one of the priority issues of environmental health in Kazakhstan, which is due to the steady increase in water consumption, qualitative changes in water sources.

We constantly interact with it - we drink it, use it in cooking, wash ourselves, water plants with it, etc. That is why water quality is so important - even a relatively small amount of harmful impurities can cause great damage to health if exposure to toxins occurs regularly. But it is impossible to determine the purity of this life-giving liquid "by eye" - many harmful substances dissolved in it are completely invisible. In order not to doubt the quality of water, it is necessary to conduct its examination.
