Where to take the water for analysis

To assess the quality of drinking water using several physico-chemical methods for its analysis. Laboratories, water quality research centers and centers of control checks deal with this issue. Of course, all these institutions are divided into public and private.

Laboratory checks

The laboratories carry out chemical analyzes of the water samples taken, determine its basic parameters, starting with color, the presence of impurities, sediment, the content of chemical elements, the presence or absence of radioactive substances. Bring water for analysis is necessary during the day, so that it does not settle. Some private laboratories specifically provide courier service to quickly and quickly conduct research. However, the rules for selecting the material are the same for everyone: you drain water from the tap for 5 minutes and only then pour the sample into a clean, necessarily glass bottle. Water should be collected slowly, as fast water intake contributes to its saturation with oxygen and the subsequent chemical reaction; water should be poured up to the lid itself to prevent air from entering there.
It is worth noting that most people are trying to hand over water for analysis to Vodokanal or the Sanitary-Epidemiological Station, but here it is important to understand that government organizations for the most part have old equipment. The result is not always true, often the data is distorted. It is best to take the water at the same time and in the state, and in a private laboratory, then you can compare the results and understand what conclusion you draw from both conclusions.


With the help of the conducted analyzes, you can find out about the presence of impurities in the sample, for example, heavy metals, the content of dissolved gases, iron and manganese, and other chemical elements.
Information about the "heavy" water or water with an abundance of impurities can serve as a reason for contacting the regulatory authorities, as well as for litigation, because the tap water must meet strict standards. River and lake water also has certain parameters, above which the reservoir may be considered dangerous and unsuitable for use (watering, bathing, etc.).
