w Gather and explain the data on the subsurface conditions of the study area.

w Explain your cross section illustrating the hydrostratigraphy of the study area.

w Describe the hydrostratigraphy of the rock aquifers of northeastern Illinois, using the case studies presented in your textbook.

w Describe the bedrock topography in the study area, explaining the relative positions of the sandstone and limestone.

w List the three major environments of deposition of glacial materials, describe the sedimentary deposits they leave, and tell whether each is most likely to be an aquifer or an aquitard.

v Using Geologic Maps

• Locate our study area on geologic maps showing Quaternary deposits,  bedrock geology, the Stack-Unit Map, and the glacial sediment thickness map.
• Read and record the information given by each map, and use it to interpret the geology of the study area.
• Explain the connection between the geologic origin of the materials at the site to the hydrostratigraphy.

v Hydrostratigraphy and Flow Systems (partly a review from previous classes)

• Recognize and delineate hydrostratigraphic units in your cross section.
• Explain the difference between lithostratigraphic units and hydrostratigraphic units.
• Describe how to delineate hydrostratigraphic units when they involve two (or more) lithostratigraphic units, or when they involve only a portion of a lithostratigraphic unit.
