RAAL oAftâ– % <br /> SYSTEMS, INC_ <br /> March 22, 2012 <br /> Company:AEI Consultants <br /> Project: Perform Sub-Surface Anomaly,Storage Tank and Utility Survey <br /> Project Date: March 21, 2012 <br /> Project Location: 678 North Wilson Way,Stockton, CA 95205 <br /> On March 21, 2012 Ground Penetrating Radar Systems performed a site survey at 678 North Wilson <br /> Way in Stockton CA. GPRS utilized ground penetrating radar, electromagnetic induction and radio <br /> detection to perform the survey.The area that was surveyed is approximately 60'x60' all findings were <br /> marked out directly on the surface using marking paint. GPRS started the survey with an EMP-400.The <br /> EMP-400 was carried in an east to west direction with readings taken every 0.5 seconds. Next used was <br /> a GSSI 400MHz GPR antenna. Scans were collected from north to south and east to west in a grid <br /> pattern. Last used was a Radio Detection 7000+ unit.This apparatus is capable of detecting radio and <br /> power frequencies. <br /> The data collected revealed one power line and two areas of sub-surface soil disturbance and one <br /> anomaly.The pictures and images below are of the project site along with the data pulled directly off <br /> the GPR 400MHz antenna and the EMP-400. Each picture will be followed by the image of data that was <br /> collected by the GPR 400MHz antenna. <br /> The diagram labeled Site Survey is not to scale and is only meant to help in approximation of findings. <br /> 6r <br /> Project Site Location <br />
