Surface Geophysical Investigation

SURFACE GEOPHYSICAL INVESTIGATION (RESISTIVITY SURVEY)

The company is equipped with latest deep penetration, generator operated, Micro Processor based, Signal Stacking A.C. Resistivity Meter & D.C. Resistivity Meter which can investigate ground water conditions, probable strata and ground water quality down to 400 m respectively. The study is useful in pin pointing sites for water wells and drilling of boreholes. Battery operated Resistivity Meter is also available with the firm to study the disposition and interstitial quality of aquifers upto 150 m and soil resistivity investigation. The Resistivity surveys have been used for locating deeper aquifers (water bearing zones) in hilly terrain, intermountain valleys, hard rocks, Kandi areas and deep-seated aquifers. The equipments are digital with computer aided facility for field data analysis. Apparent resistivity data analysis yielded highly encouraging results in pin-pointing sites for construction of tubewells and ground water structures(percolation wells, infiltration galleries etc.). The equipments have effectively been used by the company in solving problems like locating potential water bearing zones at deeper levels, demarcation of fresh / saline water interface, saline aquifers, delineation of ground water pollution areas and identification of type of the rig to be deployed. The company has conducted more than 10,000 vertical electrical soundings in the States of Punjab, Haryana, Himachal Pradesh, Uttarakhand, U.P., J & K, Rajasthan, Madhya Pradesh and Delhi.
