摘要：Our present work is to find out the suitability of groundwater for drinking and irrigational purposes within the Lefunga block of west Tripura district, Tripura and also to evaluate their seasonal variation. Water samples have been collected from ten different spots of Lefunga block. Collected groundwater samples from the study area have been analysed for the determination of some physical parameters like pH, EC, TDS along with vital cations and anions like Ca, Mg, Na, K, Fe, Cl, HCO3, SO4 and F etc. The obtained analytical data of water samples in Lefunga block suggest that the quality of water is within the standard limits of WQI categorization and acceptable for drinking purposes both in pre and post-monsoon seasons except one location having high level of iron content. Based on the analytical data, different water quality indices like sodium percentage (Na %), Sodium Absorption Ratio (SAR), Magnesium Hazard (MH), Permeability Index (PI) and Kelly's ratio (KR) have been measured for the suitability irrigational purposes. The calculated water quality indices reveal that the groundwater of Lefunga block is suitable for agricultural purpose for both the seasons.
