摘要：There are several factors influencing the water quality based on its usage. The quality of drinking water is of the vital concern for human health and life. The present investigation was aimed at assessing the water quality index (WQI) for Vishav stream. The water samples were analyzed for 11 core parameters vital for drinking water purposes. Analysis of the data revealed that the WQI values ranged from a minimum of 1.085 to a maximum of 658.79. The higher values of WQI were found mainly due to the higher values of pH, sulphate and Calcium in the stream. Pearson correlation coefficients were calculated to identify the strength of relation between the variables. Carbon dioxide and oxygen were found to bear significant negative correlation with temperature. While as Chloride, Calcium and Magnesium were significantly interrelated indicating that the hardness of the water is permanent in nature. The results support that the water parameters are desirable and the water quality of Vishav stream falls within the excellent to good category of water quality class based on water quality index values. The results of analysis were used to develop predictive models for water quality.
