Assessment of groundwater quality for irrigation purpose in Medak district, Telangana

Abstract

The present study represents the quality of ground water of Medak district of Telangana state, India during the month of November and December of year 2023. Total 168 ground water samples from bore wells were collected and GPS locations of sampling points were recorded from Medak. The ground water samples were analyzed for quality parameters physico-chemical and chemical properties viz., pH, EC, Na+ and Ca+2+Mg+2. The Sodium Adsorption Ratio was also calculated for these ground water samples. The results found that all ground water samples from Medak district were neutral to alkaline in reaction and having pH 7.02 during pre-monsoon and 7.48 during post-monsoon season respectively. The pH, EC and SAR in groundwater ranged from 6.76-8.67,0.23-2.53 (dS m-1), and 0.32-8.93 %, respectively. The concentration of cations viz., Ca+2+Mg+2 and Na+ varied from 0.8-8.6 meq L-1, 0.4-14.4 meq L-1 with mean values of 4.5,7.4 me L-1, respectively. The relative abundance of ions for most of the water samples were Ca+2+Mg+2 > Na+ for cations. The study revealed that based on SAR 100% samples were in excellent category for irrigation (
