摘要：
The article presents data on the chemical composition of water from springs of Valdai District of Novgorod Oblast. In twelve, the most known and frequently visited, sources concentrations of main ions, values of indices characterizing the pollution of springs with organic substances and mineral forms of nitrogen, as well as the content of ions of heavy metals were determined. Water from nine examined sources corresponds to sanitary and hygienic standards.
