f GROUNDWATER QUALITY AND GEOPHYSICAL STUDIES IN THE VICINITY OF TAILING PONDS OF THERMAL POWER PLANTS NEAR NAGPUR IN INDIA

Groundwater quality and Geophysical studies have been carried out in a microwatershed surrounding the tailing ponds near Nagpur in India. The study assumes importance in view of the nearby habitations using the groundwater for their drinking requirements. The study area covers approximately 60 sq km. A network of observation wells (23 nos) has been set up for groundwater quality monitoring for the major cations/anions. The results indicate that SO4 concentration has been found to be very high in few wells in the downstream of the tailing ponds. Elevated fluoride concentration (>1.5 mg/L) has been observed in only one observation well.
