Groundwater Lab Sarah Anderson ISP203L Section 17 March 26, 2008 In this lab our group hypothesized that there would be higher water pressure in the lowest unit because it is deeper, and farther down and so the water levels would be higher. At the beginning of our lab we noted the water levels of each well and which unit it was a part of. As we looked at the water levels, we also noticed that the water levels were all even with the recharge level and above the discharge level. After this, we had to

Unformatted text preview: pump the water out of well 4 and when we did this, we noticed that wells 1, 7, and 8 all went down. We then had to pump water out of unit 1 and noticed that it did not change the water level in wells 3, 6, or 9 regardless of the rate at which we pumped the water out. The observations that we came across showed us that the permeability of unit two is very low and that the lowest permeability was in unit three because it was the finest and best sorted unit of sand....
