Hydrochemical Characterization and Evaluation of Groundwater Quality of Delhi Region

  1. Tapasya Tomer

Abstract

A hydrochemical study was conducted in Delhi to identify the chemical composition of ground water and water quality with respect to drinking purpose. 22 groundwater samples from various locations in Delhi region were investigated. The various physic-chemical parameters such as pH, total dissolved solids, total hardness, calcium, magnesium, total alkalinity, chloride, fluoride, nitrate, sulphate, sodium and iron were determined. Piper diagram and water quality index were used to determine hydrochemical characteristics and water quality. Results revealed that water quality of study area ranges from good to poor but at some places water is unfit for consumption. The dominant hydrochemical facies are HCO3-Na, HCO3-Mg, Na-Cl and mixed types. It can be inferred from the hydrochemical facies that the groundwater chemistry in the area is influenced by the dissolution/precipitation.
