Quality of

water

For the majority research section in our region there is

some documentation collected of the

first class normative conditions

Results were located mainly in

acceptable borders of the classes I-II

Taking samples of water to physics-chemical analysis

Turn on the top and adjust the stream of

water so it won’t splatter. Keep doing it for about 10 or more

minutes to take a sample of water

The sample which were put into chemical

researches have to be taken into two clean bottles. Each bottle

must have got 1,5 l of capacity

Collected samples of water, supply as soon as

possible to laboratory, from the moment of

collecting

With visit to National Health
