Assessment of Water Quality Index for the Pond Water in and Around Jabalpur City, Madhya Pradesh, India
Keywords:
Groundwater, Water quality standards, Water quality index.Abstract
The present research work is aimed to know the Water Quality Index (WQI) for the groundwater and pond’s water of Jabalpur city and its surrounding areas. For this study groundwater samples were collected and various physical and chemical parameters were determined in the laboratory. For calculating the WQI, the following 13 parameters have been considered: pH, Electrical Conductivity (EC), Total Hardness (TH), Total Dissolved Solids (TDS), Calcium (Ca++) hardness,Magnesium (Mg++) hardness,Chloride (Cl-),Sulphate (SO4- -). Nitrate (NO3-),Alkalinity,Biological oxygen demand,Oxygen demand,Total colifrom. Water Quality Index for these samples ranges from 8 to 15. The high value of WQI has been found to be mainly from the higher values of Iron, Total Dissolved Solids, Total Hardness, Fluoride, in the groundwater. The final output of the analyses has been used to suggest models for predicting water quality. Spatial distribution of calculated Water Quality Index was plotted in Arc GIS environment for better visualization. The analysis of groundwater And pond water shows that the groundwater of the area needs great degree of revitalisation before consumption, and it also needs to be protected from the pollution sources of contamination.
