Abstract: The quality of the waters of the rivers of the Lake Sevan catchment basin was assessed by the investigation of water hardness, pH and permanganate oxidation (PO) value. The measurement of the hardness of the waters by the settling of salts and the determination of PO value in the water samples before and after the settling of salts gave an opportunity to separate the possible impact of salts on PO value and to assess the quality of the waters more precisely. The investigations have been clarified that PO value isn’t directly related to the level of hardness in water, and it is influenced by the qualitative nature of salts dissolved in water.
Key words: water hardness, permanganate oxidation, water quality
