Abstract
The different physicochemical parameters, including pH, total dissolved solids (TDS), alkalinity, chloride, total hardness, sulphate, and nitrate, were used to analyse ground water samples near Bhalswa Lake in the North West Delhi area of India. water samples were obtained from locations across Bhalswalake, such as: In order to determine the groundwater quality surrounding Bhalswa Lake, the concentration of pH, electrical conductivity, total dissolved solids (TDS), hardness, alkalinity, chloride, sulphate, nitrate, and phosphate was measured in groundwater samples. Bhalswa Lake is both a residential neighbourhood and a trash dump. Effects of this analysis revealed that groundwater is heavily polluted and unsafe for drinking and household operations since it includes strong chemical contaminants. Water Quality Index of groundwater at various locations around Bhalswa Lake was also found to be unsuitable, reflecting extremely polluted groundwater status at almost all sampling sites.
