Анотация: The article contains a study of River Hrazdan water quality within of Yerevan over a 6-year period (2012-2017) by some hydrochemical parameters: physico-chemical, of water salt contents, mineral nitrogen-containing substances, nitrates and phosphates, heavy metals Ag, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, Zn, Hg, As. The research included the determination of spatial (8 permanent stations) and seasonal (high- and low water) dynamics of hydrochemical parameters by a methods of principal component (PCA) and cluster analysis. A comparative analysis was done between data for 2002-2007 and 2012-2017, and geochemical series constructed. It has been established that the 5th class water quality limits protection and normal functioning of the river ecosystem, river water use in fish farming and irrigation.
