Abstract:
The ground water quality of Karimnagar district was carried out during pre and post-monsoon seasons of 2020 for irrigation purpose. Assessment of ground water quality in Karimnagar district was undertaken to study the physico-chemical and chemical characteristics of ground water and classified according to USSL (1954) classification for irrigation suitability. About 53 ground water samples were collected from different villages in Karimnagar district of Telangana state to study the physico-chemical and chemical parameters like pH, EC, cations, anions, SAR and RSC with the help of standard methods. Changes in water quality during study period was analysed and represented in terms of percent of samples in pie diagrams. The mean values of pH, EC, SAR and RSC are 7.25, 0.93 dS m^-1, 1.33 2.62 me L^-1during pre-monsoon and 7.47, 1.12 dS m^-1, 1.56, 4.45 me L^-1 during post-monsoon respectively. 34%, 17% of samples fall under Medium salinity water (C₂) and 66%, 83% of samples under high salinity water (C₃) During pre and post-monsoon seasons respectively. 9.43%, 5.7% of samples under non- alkaline water (A₀), 7.55%, 5.7% samples under low alkalinity water, whereas 18.78%, 5.7% samples under medium alkalinity water (A₃), 64.20%, 83% of samples under high alkalinity water (A₄) during pre and post-monsoon seasons respectively. All the samples are low sodium hazardous and suitable for irrigation in both seasons.
