The fact that water is the most mysterious substance on the planet is interesting. Yes, it quite so! The formula of water (H2O) open once is only "skeleton" of this substance. Actually in water (water, from the well or well) huge set of any impurity.
- - glass or plastic polutoralitrovy bottle;
- - sheet of paper;
- - handle;
- - fridge.
1. Correctly gather test. Gathering test, try to lower bucket by means of which of well you get water, is a little lower than normal. The fact is that on surface well water can be stagnant, and at the bottom – with silt impurity therefore it is the best of all to find "gold core" where water would be the cleanest.
2. Well wash up bottle in which water for carrying out the analysis will be gathered from within. Never for these purposes use bottles in which sweet drinks have been once poured.
3. To achieve more exact results, fill in water in bottle with thin stream: it has to flow on bottle wall. Thanks to such way of set, well water will not be oxygenated from air, so, no additional chemical reactions will proceed in it. Fill in water in bottle under neck and densely twirl stopper. You remember: in bottle with water there should not be air lock, otherwise results of analyses will be distorted.
4. If after capture of test it is impossible to send it at once to analyses, place bottle with water in the fridge.
5. Surely supply bottle with water accompanying note in which the following information has to be specified: place of selection of water (exact address), type of water (that is well) and also exact date of selection.
6. Give bottle with water together with accompanying note to SES, firm which is engaged in sale of filters for water, regional office of Vodokanal or laboratory. In each of these institutions there are special equipment and reactants for water quality research.
