HOMEWORK due week after exam)

 

  1. Review the synopsis of the Woburn case http://research.et.byu.edu/woburn/brief.htm

 

  1. Review the general geology of the Aberjona River valley at the web site below.  View the detailed cross-sections.

  1. Go to the well log map.  http://research.et.byu.edu/woburn/well%20logs/welllogs.htm  Create your own cross-section using wells S-76, S-72, S-82, S-63, S-21, S-22
    1. Note elevation of land surface (if given), depths to contacts between glacial outwash (sand, silt, gravel), glacial till and bedrock
    2. Construct a cross-section similar to the ones you viewed in 2. to the best of your abilities.  BE NEAT

 

  1. How did the quality of the well logs vary?  Was it difficult interpreting well logs created by differing geologists?
  2. How do you expect the hydraulic conductivity to vary between glacial outwash, glacial till and the bedrock?  Which could be an aquifer?
