Abstract
The global climate change over the years gradually affected the water quality, leading
to increased drought and flood risks and posing challenges for water management
and resource availability. The water quality index (WQI) signifies the quality of
water in terms of index number which communicates the information on overall water
quality trends for the end users. In this study, nineteen groundwater samples were
collected from hand pump, bore well and deep tube well of the Biharsharif township
area during the pre- and post-monsoon seasons of the year 2023-24. In the present
study, the quality of water was estimated by testing various physicochemical parameters
namely, pH, TDS, TH, Calcium, Magnesium, Chloride, Nitrate, Sulphate and Fluoride
and after that the quality index was analyzed in this study.
The WQI value of 110.9 is maximum and the value 38.56 is minimum in the study area.
The computed WQI shows that 89.5% of groundwater samples were found as ‘Very Good’
to ‘Good’ category. On the other hand, only 10.5% samples fall in the poor category
showing that the water is not suitable for direct consumption and needs a degree
of treatment before its utilization. However, high values of WQI in the post-monsoon
season of study area have been found to be mainly due to potential hazards leaching
into the soil and mixes with the groundwater.
