Water quality index of groundwater in different geomorphological units in Bist-Doab, Punjab, India

Abstract

In the present paper, an attempt has been made to work out water quality index (WQI) to assess the groundwater scenario of different geo-morphological units of Bist-Doab, Punjab, India. Data of 51 groundwater samples collected from piezometers, dug wells, bore wells are used. The WQI is computed using seven parameters viz. pH, Total Dissolved Solids, Total Hardness, Fluoride, Chloride, Sulfate and Nitrate. However, the WQI results show that the overall water quality class is ‘good’ and water is acceptable for domestic use but continuous monitoring of groundwater is required to protect water from any possible contamination in future due to growing agricultural activities in the area.
