Monitoring And Analysis of Water Quality of Educational Institutes of Hamirpur
Abstract
This work is based on evaluation of physicochemical parameters, calculation of Water Quality Index (WQI) and Correlation to investigate the water quality of tap water of fifteen different educational institutes of Hamirpur city (Himachal Pradesh), India. The sampling was done every month from October, 2023 to March, 2024. The parameters like pH, Total Alkalinity (TA), Electrical Conductivity (EC), Total dissolved solids (TDS), Calcium Hardness (Ca-H), Magnesium Hardness (Mg-H), Total Hardness (TH), Sulphate (SO4), Chloride (Cl), Dissolved oxygen (DO) and Biological oxygen demand (BOD) were investigated. The observed levels of these parameters were found as per BIS standards except DO and BOD which have been found slightly low and high, respectively as per CPCB. Subsequently the Water quality index was calculated from all the measured parameters. The Average value of WQI for these parameters was found to be 14.59±0.21, which indicates the excellent status of water. The correlation coefficient result shows that different physicochemical parameters have significant positive and negative relationship with each other and suggests that the water has an adequate mineral content, minimal organic contamination, and acceptable DO level.
