Groundwater lab report Essay Example

Groundwater lab report Paper Although you are only required to respond to the questions in this worksheet, you are strongly encouraged to answer the other questions from the text on your own; doing so will make answering the required questions easier. Questions are from Conscience Laboratory, 5th De. (up. 213-226), by T. Freeman, 2009, New York, NY: John Wiley Sons. Reprinted with permission. Lab Questions 12. 2 (A) How many cubic kilometers of water reside within groundwater? The answer is 8. 4 million cubic kilometers of ground water. 12. 2 (B) How many more times abundant is groundwater than water on land? The answer is 0. 2 times more than that is abundant on land. 8. 4: 0. 2 8. 4/0. 2 = 42 Ground water is xx more abundant 2. 5 So what do you suppose happened when over-pumping of the saturated zone was stopped by that other California state agency? Levels would begin to rise up to a point where the aquifer shell was not damaged from drying out. 12. 6 Can you imagine what happened when the water table rose? Hint: Asphalt and concrete are only so strong. As water levels rise so would the settle landscape above causing the asphalt and concrete to shift and crack from ground pressure. 2. 7 If, for the model in Figure 12. 11, Hal were 506 Ft, h2o were 497 Ft, and I were 50 Ft, what would be the hydraulic gradient (in percent) between well #1 and well #2? Answer: 6 % (506 497)/1 50 = 0. 06 * 100 = 6 % 12. 11 If contaminants were to find their way into groundwater at Acme Industries, in which well would those contaminants be more likely to appear the well at the Smith farmhouse, or the well at the Jones farmhouse? The answer is the second one: Jones farmhouse 12. 18 Which of the six wells in Figure 12. 25 in Chi. 12 should be flowing artesian wells?

AAA and B, two depressions are occupied by water, whereas others are dry. (A) Explain this presence and absence of ponds in these two figures. In figure A, the pond was prevented into diminishing due to the saturated area brought about by the resistant clay in the first pond in figure B, in the other hand, the first opening is a non-resistant type of land and the second opening is a resistant material that can hold water. (B) If the two ponds were perennial (i. . , year-round) ponds, because of intersecting the water table, how would the presence or absence of water in he other depressions differ from that which is shown? Springs are formed either from a destroyed steam, sinkholes, or valleys. Caves are also formed from saturated area of land where a land will sprout and will construct as caves. 12. 20 Judging from what you learned from information in Figure 12. A AA in Chi. 12, how might one seal a leaking stock pond? Hint: Were talking three steps here, with steps #1 and #2 being the draining and restoring of pond water. The first thing that you should do is to drain the water in the pond, then put resistant clay o the bottom of the hole. Once done, you can fill back with water. 12. 21 Examine Figure 12. 22. At a glance, several ponds might be mistaken for stock ponds. However, there is evidence indicating that the large pond at coordinates P-5 is surely a sinkhole. What is that evidence? Hint: The evidence appears in the relationship between the pond and a man-made feature. The answer is that the rock bridge will hold the land and will not permit water to be drained 12. 5 Do water levels in these three lakes (as well as others) appear to be overfed by the vagaries of spotty rainfall and random surface drainage, or do they appear to mark systematic elevations on a water table? Hint: Notice the elevations of the bottoms of dry sinkholes relative to the water levels in ponds. The answer is elevation of water table. Lab Summary Address the following in a 100- to 200-word summary: Summarize the general p rinciples and purpose of the lab. Explain how this lab helped you better understand the topics and concepts addressed this week. Describe what you found challenging about this lab. Describe what you found interesting about this lab. Write your summary here: This lab experiment is provided in order to comprehend the water system in the planet. Even it be a pond, a hole or a lake, one can never really understand the reason why the water ended up there. I also share this same difficulty. But with the aid of this laboratory experiment, I can now comprehend why the water ended in there. Also understand something unless you see it with your own eyes. I realized that there are various materials and information that are interesting to study and to know in these bodies of water.
