How do I know if the tap water I drink and use to cook is clean?

First of all, remember that water that is abstracted, treated, tested and delivered to consumers through drinking-water supply networks and via tap is safe to use, but that does not mean that it is completely sterile. If the water is treated using membranes and does not contain dissolved salts, then such water is called distilled water. The use of water purified in this way in the daily diet can endanger human health, as distilled water drain out salts in the body. The water that would be recommended for human consumption and provided through drinking-water supply networks contains various microelements and macroelements, such as Mg, Ca, K, Na, which have a beneficial effect on the human body. If the water from the drinking-water supply networks in your home is clear, with a pleasant refreshing taste, without a specific colour and smell, then you can be sure that the water is clean, safe and suitable for drinking.
