Abstract

To study the evolution of hydrochemical characteristics and the quality of irrigation water from a suburban river, a total of 54 water samples were collected from Xinbian River in Suzhou City (Anhui Province, China) from December 2019 to May 2020. Piper diagrams, Gibbs diagrams, and multivariate statistical analysis were used to analyze the hydrochemical characteristics and main ion sources. Research results showed that the content of main ions increased continuously from December 2019 to May 2020, among which SO42- and F- exceeded China’s surface water quality standards in April and May. The main hydrochemical type was Na-SO4, accounting for 77.77%, of water samples with the main ion components found to be related to rock weathering. Correlation analysis and principal component analysis showed that agricultural non-point source pollution was the main factor affecting the water quality of the Xinbian River. Overall, the evaluation index of irrigation water shows that Xinbian River was suitable for irrigation utilization, although the effects of magnesium damage should be prevented.

Highlights

Valappil et al (2020) assessed surface water from the Limbang River Basin in Kalimantan, using Piper diagrams, Gibbs diagrams, and multivariate statistical analysis, showing that atmospheric rainfall and rock weathering were the main factors affecting the chemical characteristics of surface water in the study area
Wang et al (2019b) studied the water chemistry characteristics, control factors, and water quality of the Nu River, finding that rock weathering was the main source of ions and that most Nu River water samples were suitable for irrigation use
