Georeferenced groundwater samples collected from Thimmajipet mandal, Mahabubnagar district were analyzed and evaluated for their suitability for irrigation. Out of 49 samples, 12 per cent samples recorded pH > 8.5 and electrical conductivity varied from 500 to 5130 µS cm-1. All the samples have high Mg2+ content and 92 and 94 per cent samples have high Ca2+ and Na+, respectively. Among the total groundwater samples 59 per cent have high sodium hazard, 80 per cent with high magnesium hazard, 7 per cent with high Mg/Ca ratio and 100 per cent with very high permeability index. Water samples were classified as C3S1 (29%), C3S2 (39%), C2S2 (2%) and C2S1 (4%). In general, the groundwater in Thimmajipet mandal is unsafe for long-term irrigation use.
