ABSTRACT
The present study deals with the arsenic , fluoride levels in relation to few physical parameters in the ground water samples of Bagepalli taluk, Chikkaballapur District, Karnataka. In this study, the water temperature varied from 25°C during November 2010 and a maximum of 35°C, May-2011 at all the sites. pH concentration varied from 7.0 during January-2011 at S7 to a maximum of 8.8 in September 2010 at S1 sites, indicating neutral to alkaline nature of water. The electrical conductivity values are found to be in the range of 302 to 2718 mhos/ cm. In the present study, high fluoride content recorded with 5.9 mg/L at S8. Peak arsenic content recorded 0.05 mg/L at S1 and low 0.01 mg/L at S6. No seasonal variations observed in arsenic content. In many samples, the fluoride is exceed the permissible limits of WHO and BIS standards. It is concluded that the ground water quality is mainly affected by seepage of sewage, waste water and urban runoff into the ground waters, due to lack of sewerage facilities. Dental fluorosis is recorded in the study area.
