A numerical study of the surface water using levels of the organic pollution indexes: comparative characteristics and educational opportunities

Abstract

The current study investigates different approaches to calculating the organic pollution index of water and comparing the obtained numerical levels using statistical methods with the environmental assessment of the state. The object of the current study is the Styr River water at two sampling sites before and after the point source of pollution, namely, the water discharge of the power plant. The paper explores the possibilities for teaching the topic of environmental pollution by organic substances and allows students to gain practical knowledge of environmental assessment and data comparison. Moreover, statistical methods, including correlation analysis, were used in the research because of their ability to assess variations in river water quality and identify potential sources of water pollution. The author's conclusions obtained as a result of this study can be used when teaching environmental issues to students. The strengths of this study are that it focuses on environmental issues.
