Well water is not always crystal clear. Who knows, maybe she's not reading too much anymore? The sounded theses are already an excellent reason to think about checking the quality of drinking water at your summer cottage. You can check it without the help of a laboratory, only on your own.
1. Checking with detergent
We take some water from a well or well, pour it into a clean container. Then we take the dish detergent and add a small amount. Next, shake it with a clean spoon or straw. If the foam does not appear or there is very little of it, the water is too hard. If there is a lot of foam, then everything is in order with water in terms of hardness. Increased hardness indicates excess salts and alkaline earth materials in the water.
2. Checking with tea
We brew regular black tea and pour it into a transparent glass so as not to fill it completely. Next, we take water for testing and add it cold to the freshly prepared drink. If the tea turns to a peach color after mixing, then most likely everything is in order with the water. If the tea is cloudy or precipitated, then you cannot drink such water from the well.
3. Checking with potassium permanganate
We take potassium permanganate and add it to the water taken from the well for testing. If the liquid has acquired a light pink color, then everything is most likely in perfect order with the well water. If potassium permanganate is acquired in any other color, for example, yellow, then drinking such water is not just impossible - it should be handed over to the laboratory as soon as possible.
4. Testing by time
We collect water in a glass, cover it with a lid and put it in a dark place for several days. We return to the glass no earlier than 3 days and look carefully. If a sediment has appeared on the bottom or walls, algae or plaque has formed, some kind of film has appeared on the surface of the water, such H2O should not be used.
5. Checking with a mirror
To work, you need a clean, degreased mirror and an eyedropper. We splash a few drops of water on the mirror and wait until it dries. If streaks remain in place of the drops, then the water was extremely dirty. You definitely can't use this.
