Assessment of groundwater quality for drinking and irrigation purpose using hydrochemical studies in Dera Bassi town and its surrounding agricultural area of Dera Bassi Tehsil of Punjab, India

Abstract Present research aims to assess the suitability of groundwater Dera Bassi town (Punjab) and its surrounding agricultural area for drinking as well irrigation purpose. Thirty samples were collected (in February 2020) analyzed various physicochemical parameters. Results analysis compared with Indian (IS 10500:2012) WHO (2006) standards ascertain purpose, it has been found that results almost all parameters except alkalinity (at few sites) are within permissible limit. The pattern ionic dominance was observed in order Ca 2+ > Mg Na + K cations Cl − NO 3 SO 4 2− F anions. Further, according Kelly’s ratio, sodium adsorption percentage, corrosivity ratio permeability index, be fit However, magnesium residual carbonate revealed under study is not purpose at some sites. plot SAR values versus EC US Salinity Laboratory diagram majority fall water type C3-S1 (high salinity—low SAR) 36.77% C2-S1 (medium SAR).
