GPR Data Analysis <br /> The analysis of GPR data is primarily limited to visual inspection of the graphical records. We <br /> inspect the records for reflection patterns that indicate a change in stratigraphy or the presence <br /> of discrete objects. In areas with uniform stratigraphy and no buried objects the GPR profile will <br /> appear as a series of parallel, horizontal dark and light bands. In areas with contrasting <br /> stratigraphy, especially an area with dipping beds, or an area with a highly reflective discrete <br /> object (such as an UST or a pipe), the reflection patterns are quite different. Dipping beds often <br /> appear as a series of inclined bands on the GPR records. A UST or pipe will appear as an inverted <br /> "U"superimposed on horizontal banding. For this investigation, our inspection of the GPR records <br /> was primarily focused on finding discrete objects. <br /> • <br /> • B-2 <br />
