Analysis of Aquifer Data
(From CW Fetters Lab manual)
1.
A new well has been drilled to test an aquifer. It was pumped at 220 gpm,
with measurements being taken at an observation well located 624 feet away.
The data are:

Remember to show all work.
The purpose of this exercise is to get you thinking in terms of the "plumbing
system". You will have both geologic cross-sections and geologic maps to use in
your analyses. Remember, that the relative

In this lab we consider the flow of groundwater through porous and fractured media.
We begin by evaluating water level data to determine the direction of groundwater flow.
When there are water level elevations from wells the direction of g

All lab exercises are expected to be turned in with a legible cover memo. You
will lose 10% of the grade for a missing memo. This is where you integrate the
results of your work. Proper layout of the work will aid the grader in
