Abstract :

Geophysical logging application was incorporated for the perusal of the groundwater analysis. The study area involves the parts of the Saket area, situated in the Indian capital Delhi. For the purpose of study VES(vertical electrical sounding) method was adopted to reach to desired analysis. The study carries the objective of an analysis of the condition of groundwater along with the investigation of the geological situation. Abem Terrameter SAS-300c system with the with Geomac II, ABEM SAS log200 system with Geomac III were used in the study to perform the VES of the Schlumberger configuration along with the tubewell geophysical logging. Lithological investigation of the tubewell depicts the presence of alluvial topsoil, Badarpur sand, fractured and weathered rock along with the sandy silt and silty sand for subsurface of soil. Also, the presence of four geoelectric layer found. In these layers the fourth layer that is observed at a depth range from 15 ft to 450 ft, were found with the aquifer and 50 to 2000 Ωm resistivity were observed for this layer consisting aquifer. Geophysical logging analysis depicts the observation results for total dissolved solid in aquifer as 430 ppm. the obtained limit of TDS is found to be in standard limits, as the standard limit is 500 ppm set for the potable water by standard organization of India. Ground water development is found to be feasible for the fourth layer, since the layer is observed as potential non-conductive zone in the study area.
