The document discusses developing a hydrogeologic conceptual model. It describes taking boring logs and other subsurface data and integrating that information to create: - Strip logs showing soil/rock types across a site - Sections showing soil/rock types and stratigraphy in 2D - 3D geologic models to understand the subsurface in 3 dimensions The goal is to conceptualize the large-scale stratigraphic units and hydrogeology based on detailed boring log data and other site characterization. This conceptual model informs further hydrogeologic analysis and site investigations.
