Over the past decades, many adults have convinced us that tap water is not suitable for drinking. It was considered contaminated with harmful substances, and its consumption could lead to digestive issues such as diarrhea or vomiting. In this text, we will examine whether these concerns are justified, whether it makes sense to replace tap water with bottled water, and present the most effective methods for water purification.
Is it okay to drink tap water?
Water workers are obliged to comply with EU standards developed by the World Health Organization (WHO) when water demand was much higher and the standards are not so strict, so the water they supply to our homes must also meet these requirements. That is why we can reach out to them to quench their thirst without fear of possible health consequences. This negative opinion was born in the 1970s and 1980s, when the demand for water was significantly higher and not so critical. The effect also depends on the quantity, not the quality of the water supplied.
The best water filters
The disadvantage is that, unfortunately, they lead to the demineralization of the water, and therefore the removal of the most desirable single mineral components. However, we can also apply to the condition of our water pipes, or in the case of domestic wells. It is worthwhile then to look for special filters that purify the water from bacteria, pollutants and metals. Their disadvantages are that they unfortunately lead to water demineralisation, and thus eliminate the desired single mineral compounds. We can, however, also look for the mineralisers that enrich fertile water in the places where we live.
