r� 4. Data Reduction <br /> The data compiled from the soil borings is summarized and analyzed A narrative summary of <br /> the soil characteristics is also presented The soil boring logs are checked for the following <br /> information <br /> • correlation of stratigraphic units among borings, <br /> • identification of zones of potentially high hydraulic conductivity, <br /> • identification of the confining layer, <br /> • indication of unusual/unpredicted geologic features (fault zones, fracture traces, <br /> facies changes, solution channels, buried stream deposits, cross-cutting structures, <br /> pinchout zones, etc ), <br /> • continuity of petrographic features such as sorting, grain-size distribution, <br /> cementation, etc <br /> Soil boring/well locations are plotted on properly scaled map If appropriate, soil stratigraphy of <br /> the site is presented in a scaled cross section Specific features that may impact contaminant <br /> migration, (fault zones or impermeable layers) are discussed in narrative form and supplemented <br /> with graphical presentations as deemed appropriate <br /> f� <br /> Main\D\Environmenta[\ParmarTexaco\WorkplanN042003 wpd <br />
