FINAL EXAM FOR

WELCOME TO THE FINAL EXAM

You may grade your answers THREE times before submitting your exam. We developed this exam from specific questions and concepts taught during the course and tutorials. You may use your course notes and revisit the materials.

Please do not share the link, thank you. We ask you to complete the Final Exam and submit it within 30 days after you receive it.

Good luck on the Exam.

If a pumping test is to be performed to assess the impact of a lateral aquifer boundary, which one of the following is not recommended?
  (choose one)
 
Conduct the test at the highest possible pumping rate
 
Continue water-level monitoring through the recovery period
 
Locate an observation well between the pumping well and the suspected boundary

None of the above
 
18.
Slug testing measures:
  (choose one)
 
hydraulic conductivity

19.
Pumping water continuously from a well is considered a type of slug test.
  (choose one)
 
True
 
False
 
20.
The initial water-level change should be:
