Hydrochemical characteristics were carried out in and around Lingala area of Kadapa District, Andhra Pradesh to ascertain the suitability of groundwater for irrigation/agricultural purpose. 22 groundwater samples were collected and were analyzed for pH, EC, TDS, Ca, Mg, Na, K, CO3 and HCO3 by standard methods. The mean concentration of cations is in the order Na> Ca> Mg> K, while for anions it is HCO3> CO3.To ascertain the suitability of groundwater for irrigation purposes, hydrochemical parameters of the study area have been evaluated for their chemical composition. The suitability of groundwater for irrigation has been evaluated based on various chemical parameters such as Sodium adsorption ratio (SAR), Sodium percentage (%Na), Residual sodium carbonate (RSC), Kelley Ratio (KR), Residual sodium bicarbonate (RSBC)
