HydrogeologicMapping Tasks

Your lab report will consist of the following items:

  1. Water Table Map
    1. Draw ground water table contours on Fig. 6.1 in colored pencil using a 10 foot contour interval. Where data is absent, follow the topography. Water table contours should meet topographic contours only where water is at the surface! Save a pristine copy of Fig. 6.1 in case of errors.
    2. Draw representative ground water flowlines (4-5, perpendicular to the contour lines). The flowlines show the probable path of groundwater.
    3. In red, draw the most likely path that a groundwater nitrate plume coming from the Golf Course feeding Bullfrog Pond would follow. Also draw the most likely path for a chemical spill from the location of Point 1.

  2. Hydrogeologic Cross-Section
    1. Draw a topographic cross section which passes through the hand-dug well (Point 1), the canoe trail (Point 7), the Wind Mill (Point 8) and Wilson Creek (Point9))
    2. Draw on it the ground water table. Things like scale, horizontal distance, elevations and orientation of the cross section are mandatory.

  3. Turn in your final lab report within a week of the last lab to the TA or Geosciences office. Other group's data need not to be reported in this lab. Your hydrogeologic map will serve as the required graphical summary. Discuss general trends in probable groundwater movement at the Museum, and how that movement differs from surface water movement and storm-related overland flow.
