In June, the action for free water analysis was held for residents of Technopark “Idea”.
The purpose of the event is to make sure that the water used is suitable for use and meets the requirements of sanitary norms and regulations (SanPin 2.1.4.1074-01, SanPin 2.1.4.1116-02), as well as to show the resource potential of the laboratories of the Technology Transfer Center.
A total of 30 water samples from different sources were analyzed. Bottled water (“Raifsky istochnik”, “Sestritsa”, “Hotninskaya”, “Kluch zdoroviya”), natural underground water from the wells of Vysokogorsky, Laishevsky, Zelenodolsky districts of the republic, spring water “Arkatovo”, water from the aqueduct of various districts of Kazan and Zelenodolsk were studied.
The water analysis was carried out on 38 indicators. Basically, all the obtained values of indicators meet the standards of SanPin.
Some samples of water from the well in the Zaimische region showed a slight excess of the maximum permissible concentrations of silicon and aluminum, and in the water sample taken from the well in the area of the village Vasil'evo was established an excess of the standard for iron ions. But it is natural underground water and such uncritical deviations are possible.
In two samples of tap water, the permissible norm of nitrates was exceeded. In the sample from the Zelenodolsk water supply the value of the rigidity index was exceeded. All samples of bottled water meet the requirements of SanPiN.
