QUALITY CHARACTERIZATION OF GROUNDWATER IN MATHADIVAGU BASIN OF ADILABAD DISTRICT, TELANGANA STATE, INDIA

Mathadi vagu basin is located in the northern part of Adilabad District, Andhra Pradesh. Mathadivagu is a tributary of Sathnala River which is a tributary of the Penganga River. 37 water samples are collected at various locations covering different lithounits to understand the groundwater chemistry and their suitability for drinking and irrigation purposes. Study of groundwater chemistry in this area indicates that the waters are of Mixed Cationic and anionic Na dominating bicarbonate water, Mixed Cationic Mg dominating bicarbonate water, Mixed Cationic and anionic Ca dominating bicarbonate water, Mixed Cationic Ca dominating bicarbonate water, Mixed Cationic Na dominating bicarbonate water. Graphical treatment of chemical data reveals that, the area has basic water, whereas the Battisamargam area is dominated by secondary alkaline water, and Umdam and Dahegam villages have strongly acidic water. Graphical representation further shows that most of the area has medium salinity?low sodium water useful for irrigation purposes. High salinity-low sodium and high salinity-medium sodium waters are present in some areas.
