Assessment of groundwater quality by using water quality index (WQI) in the Karchhana tehsil of Prayagraj district

Author(s):

Abstract:
The groundwater quality analysis revealed that all groundwater quality parameters such as pH, total dissolved solids (TDS), electrical conductivity (EC), Total hardness (TH), calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+), bicarbonate (HCO3-), chloride (Cl-), sulphate (SO42-) and nitrate (NO3-) were found to be within the maximum desirable limits in all groundwater samples when compared to both WHO and BIS standards. On the basis of this, it is possible to say that the groundwater of the study area is suitable for drinking and domestic purpose. Based on the result findings of the all irrigation quality parameters such as Electrical Conductivity (EC), Total Dissolved Solids (TDS), Sodium Adsorption Ratio (SAR), Percentage Sodium (Na%), Kelly’s Ratio (KR), Magnesium Adsorption Ratio (MAR) and Permeability Index (PI), it is conclude that the groundwater of the study area is also suitable for irrigation. The values of water quality index (WQI) ranged from 16.82 to 51.68 with an average 37.05. According to the obtained WQI values, only 20.00% of the groundwater samples are fall in the “Excellent" category, 73.33% are in the “Good” category and remaining 6.67% are in “Poor” category. Based on this result, the groundwater of the study area is "Good" for drinking, irrigation and industrial purposes.
