Below is a table with data collected during an Electromagnetic survey in an area underlain by sedimentary rocks. The survey was conducted along 1 traverse line to investigate the possibility of identifying the best sites for groundwater. For the survey, a Tx-Rx separation of 20m was employed for both the VCP and HCP coil orientations. a. Using the values in the table below, construct your conductivity curves. / b. What is your geologic interpretation of the data, considering the area is underlain by sedimentary rocks? Identify the recommended site to drill your well.
