Abstract

This study is based on groundwater physicochemical parameters and their correlation with industrialpollutants to evaluate the quality of groundwater near the catchment area of Kothari River (Bhilwara).Kothari River originates from the patches of Aravalli Hills and flows through the Rajsamand and Bhilwaradistrict of Rajasthan for about 145 km. In Bhilwara, the catchment area of Kothari River has many textileand other industrial units and these industrial units disposes large amount of untreated toxic industrialpollutants in the Kothari. The groundwater resources near Kothari River has greatly been affected by theuntreated textile and other industrial disposals. This research work was studied the effect of industrialpollutants on the quality of groundwater near Kothari River. The groundwater was bottled from twelvesampling sites during April-May, 2021. The groundwater quality parameters are pH, electrical conductivity(EC), total dissolved solids (TDS), total hardness (TH), chloride (Cl–), fluoride (F–), sulphate (SO42–),biochemical oxygen demand (BOD), chemical oxygen demand (COD), iron (Fe), lead (Pb), zinc (Zn), nickel(Ni), copper (Cu), cadmium (Cd), chromium (Cr), arsenic (As), etc. It was perceived that the physicochemicalproperties of groundwater near Kothari River (Bhilwara) were not as per drinking water standards of BISand WHO, and found unsuitable for drinking purposes. The correlation between quality parameters andindustrial pollutants shown that the groundwater near the catchment area of Kothari River werecontaminated with untreated disposals of textile and other industrial pollutants.
