Abstract: A detailed gravity data obtained from SRTM agency over a part of Prakasam Alkaline province has been interpreted. Interms of depths, attributing different densities and density contrast a two dimensional modeling has been attempted. A gravity profile between 15.4 N Latitude and 79.5 E Longitude of 100km from Kandukuru to H.M.Padu traversing Kanigiri plutonic complex has been selected. The basement depth has been estimated as 3.2 km on an average. The nature of the negative gravity anomaly has been interpreted interms of geology, geochemistry. The physical parameter density is essential in interpreting gravity anomaly. An attempt has been initiated to explain interms of geochemical and geological process. Further "negative" nature of the anomaly has been explained. Keywords: Alkali Granite, Gabbro, Negative Bouguer Anomaly, Pluton, Density Contrast.

Abstract: The work investigated groundwater contamination in the study area using Vertical Electrical Sound technique and Physio-chemical analysis of soil and water samples within the vicinity of the Site. ABEM Terrameter SAS 4000 was used to carry out the geophysical survey. The VES data were plotted as pseudo and resistivity-sections so as to reveal the spatial distribution of the contaminant plumes. The interpreted VES data observed in the dump showed contamination plume as low zone with resistivityvalues between 1-20.5Ωmfrom the surface extending to a shallow aquifer of 5.8m, while the VES observed at the area free of waste dump showed a resistivity values of 174-178.5Ωm from the surface to the aquifer which is free from being polluted. The Physio- chemical analysis of soiland groundwater showed elevation in some of the parameters.

Abstract: The determination of subsurface stratification and aquifer characterization were carried out at Federal College of Education (Technical), Gusau using the Schlumberger electrical resistivity array with maximum current electrode separation of 200m. Twenty four Vertical electrical soundings (VES) were conducted along six profiles.WinGlink software has been used in interpreting the results. Two and three subsurface layers exist in the study area. The topmost geoelectric layer has resistivity mostly within the range of 1-522.The lithology of the topsoil is mainly clay to sandy clay.
