A QUANTITATIVE ANALYSIS OF VLF DATA FOR GROUNDWATER EXPLORATION IN A HARDROCK TERRAIN IN OSMANIA UNIVERSITY CAMPUS, HYDERABAD, TELANGANA STATE, INDIA.

Groundwater exploration is reported in the hardrock terrain of Osmania University Campus, Hyderabad area, (78031?00?E Longitude to 78032?30?E Longitude and 170 23?48? N Latitude to 170 25?42?N Latitude) Telangana State. Nineteen (19) VLF traverses were conducted with 10m interval. VLF-EM is carried out using ABEM WADI equipment to locate the spatial location of the aquifer zones like fractures, faults, dykes and EM Conductors. Applications of Fraser filter for the real and imaginary components are aided in filtering the noise and refining the raw data for location of conductive zones. A Karous Hjelt filter pseudo section reveals the nature of conductive, dip and depth of these conductors and shallow linear conductors are mapped and also identified 52, subsurface fractures which are highly groundwater potential zones.
