Abstract
Natural background concentrations have been used to assess the chemical status of the Debed River basin. Natural background concentrations (BGC) of hydrochemical parameters are calculated by the function of theoretical logarithmic distribution. A site-specific classification system for the assessment of the water quality of the Debed River basin based on BGC is developed. The water quality of the Debed River from the town of Spitak to the city of Vanadzor is ranked as a "moderate" quality, after Vanadzor -"bad" and after the mixing of the rivers Dzoraget and Marts to the Armenian-Georgian border -"good". The main pollutants in the basin are revealed and their impact is assessed.
