Revealing Fluoride Contaminated Aquifers in Hard Rock Terrain Using Electrical Resistivity and Induced Polarization (IP) Methods Conference Paper uri icon


  • The presence of Fluoride (F) in groundwater is a common phenomenon in India as well as worldwide. Its location can be identified directly through hydrochemical analysis. This analysis was carried out for groundwater affected by the F contamination in Kurmapalli watershed (located 60 km SE of Hyderabad city), Nalgonda district, Andhra Pradesh, India. The hydrochemical results showed that F varied from 0.71 to 19.01 mg/l and its concentration exceeded the permissible limit (i.e., 1.5 mg/l) in 78 of the total 32 samples analyzed. The highest F value (19.01 mg/l) was found near Madnapur village, which is located in the central part of the watershed. Resistivity and Induced Polarization (IP) surveys were also carried out to reveal the zones, where elevated F contaminated groundwater exists. The objective of this paper was to highlight the utility of resistivity and IP surveys, using hydrochemical constituents as constraints, for delineation of contaminated/polluted groundwater zones in hard rock areas. 2010 ASCE.
