The findings suggest that the majority of the respondents formulate their perceptions using non-scientific methods like sensorial and heuristics. Non-parametric tests such as Kruskal Wallis, Mann Whitney U-test and One-Sample Wilcoxon Signed-Rank Test were used to analyse the data. The method applied involved a structured questionnaire survey of 2706 respondents and four focused group discussions with people residing within two kilometres of the river bank. Using the stratified semi-purposive sampling process, the study explores the perception of people residing along the river Yamuna in India. The paper aims to understand how the public perceives river water quality and related risks and behaviour.
