Abstract
To evaluate hydrogeochemical evaluation of groundwater for drinking & irrigation practices in and around Lakkireddipalli and Ramapuram, Y.S.R District, Andhra Pradesh, India, thirty groundwater samples were collected during March 2018. Most of the groundwater samples are above the safe limits of W.H.O standards. Groundwater is exceeding the permissible limits of TDS, TH, EC, chloride and sulphates. Geogenic and anthropogenic sources are the main contributing factors for fluoride and nitrate respectively. Rock dominance is the predominant hydrogeochemical factor controlling the water chemistry. Piper's diagram reveals that water is of mixed Ca Mg Cl type. Irrigational water quality indices reveal that majority of groundwater samples falls under the unsuitable category and application of this untreated irrigational water is harmful for the crops and decreases the crop yield. Hence more saline tolerant crops could be suggested to combat soil salinization and application of lime/gypsum may be suggested to bout the soil permeability.
