Abstract :

The objective of our study was to determine the groundwater quality in Mathadivagu basin, Adilabad district, Telanagana State, India. The study area lies between N. latitudes 19° 50 48" and 20°1330" and E. longitudes 78° 28 25" and 78°5800" with an area extent of 525 sq. kms. The current status of alluvial aquifer in the Mathadi vagu basin, where the nitrate pollution of groundwater is being increasing along the last decades. A multi approach methodology using hydrogeology, nitrate concentrations. The analytical results revealed that the groundwater in the major part of the area is highly mineralized with high concentrations of Nitrate. Out of 37 ground water samples analysed, 31 samples were found to have nitrate concentration more than 45mg/1. The maximum concentration of nitrate in the area is 407.4 mg/l. The concentration of nitrate in excess of the permissible limit i.e., 45 mg/I in drinking water causes Methaemoglobinemia, particularly in infants. Agricultural practices in the study sites are the main cause of serious nitrate pollution given the superimposition of high nitrate concentrations with the distribution of irrigated perimeters. High nitrate levels are associated with high values, clearly indicating that significant quantities of evaporated irrigation waters infiltrate along with fertilizer nitrate to groundwater system.
