COMPONENT ANALYSIS ASSESSMENT OF NEGLINKA RIVER WATER QUALITY DYNAMICS

Summary/Abstract: The article is concerned with the problem of small rivers’ pollution. Materials reflecting dynamics of Neglinka water quality are presented. The river flows through the territory of the city of Petrozavodsk (Republic of Karelia). Comprehensive results of the water analysis conducted in 2013 and 2014 are provided. The study of the water quality was based on ten hydrochemical indicators. The obtained results take into consideration both the seasons and locations of the places where the samples were taken from. It was proven that during the transit through the city territory the water quality of the river worsened: five from ten studied indicators exceeded the Mac values. A statistical assessment, based on the principles of component analysis, helped to reveal certain dependences between different hydrochemical indicators. It was concluded that the process of monitoring waters of the river Neglinka should be continued.
