Can you drink tap water?
No one probably has any doubts that we should care for the environment. Many people would like to contribute to the care of our planet, but on the other hand there is concern, for example, about whether drinking tap water is safe. And if it is not – should we then produce plastic bottles and drink bottled water, if we know that bottles negatively affect the environment, and plastic for our health? Or maybe there is another solution for this?
Water tests from water supply units should not raise any doubts. It seems that tap water is safe for our health and you can drink it, however, is this water really healthy?
Water standards in Poland
It is worth knowing that since Poland joined the European Union, the condition of tap water has improved significantly. Several things had an impact – above all standards and increased water control. In some cities, so-called biomonitoring is used. Before the water goes to our taps, it undergoes filtration and treatment processes. Purification of water is a multi-stage process, at the end of which pure, unpolluted and potable water is obtained. And what about chlorine? Before entering the water supply network, it goes to a special tank in which it is disinfected with chlorine. The task of chlorine is the destruction of microorganisms, thanks to which water flowing out of the central water and sewage system may be safe to drink without boiling. As we know, however, in practice it happens that we can smell chlorine in water.
Laboratory tests show that tap water meets microbiological standards. Water in the waterworks is regularly inspected by state inspections, so that even if there is any danger, all residents are immediately informed. However, letting water suitable for consumption into the water supply network does not mean that it will go to our taps in the same condition. The quality of water is always tested in the central water and sewage system, ie in the place where it is going to reach the pipes leading to our taps, and its quality changes during transport – the quality of urban water supply network affects it (the further from the central office, the more worse) and the quality of the internal home network. These networks are rarely studied (if they are tested at all), so they can often be covered with sediment causing changes in water quality, and the pipes and other infrastructure can be made of materials that will rather be polluted chemically and exposed to secondary pollution. And the quality of urban water supply networks and the quality of the internal home network mean that the water will not have the quality of drinking water.
If we draw water from our own wells, which are not controlled, it is absolutely necessary to examine it to be sure that it has the quality of drinking water.
And what about filtering?
Commonly used methods of water filtration are the use of mechanical filters – they retain only insoluble compounds in water, but all other compounds pass through. Filter filters with active carbon are another type of filters used. Activated carbon retains a large amount of soluble compounds (including chlorine). More complicated (and more expensive) devices are osmotic filters. Osmotic filters contain a mechanical and carbon filter, but the most important method of purification is reverse osmosis – it is the best method of filtering water, removing microorganisms and all chemical compounds. However, osmotically filtered water contains few minerals (it is soft water). Of course, minerals are necessary for our lives, but … their absorption from water is not too great. Advanced osmotic filters additionally contain functions such as water structuring (arranges water molecules, giving them hexagonal or hexagonal structure making it so-called living water), ionizing and reducing the redox potential (water saturation with active hydrogen), alkalization and additional mineralization.
To drink or not to drink tap water?
If you are wondering if the water in your home is safe to drink every day, take a sample and take the test. Then you will be sure that the water quality is good. Without research, do not drink tap water, it can be risky. Eat boiled water and let it evaporate for several hours. If you have the option, use good quality filters.
