How to determine the quality of tap water without an examination: one trick will help
A simple trick will help confirm or disprove your guesses.
Many people are afraid to drink tap water. Most people only drink it after the liquid has been filtered or boiled.
Only a few believe that tap water is crystal clear. But how polluted it is can be checked without a special examination.
There is a simple trick that requires any glass container.
You need to fill it with tap water and put it in a dark place for 2 days. This time will be enough to get a certain result.
The presence of impurities is indicated by a number of signs. Firstly, a coating forms on the walls of the container. Secondly, the water may acquire a greenish color.
In some cases, an oily film may form on the surface of the water.
Any of these signs indicate that the water is not of the best quality, so you definitely shouldn’t drink it from the tap.
