Question
Chapter 14, Problem 1CR
To determine
The reason why the real cost of gold is more costly than what most people pay for it. Give some examples of costs not accounted for.
Expert Solution & Answer
Answer to Problem 1CR
Mining of gold is carried out using cyanide. It requires a huge workforce and money for the extraction of gold. Thus, the real cost of gold is more than that paid by people. In addition to this, cyanide also has harmful impacts on nature.
Explanation of Solution
The real cost of gold is less than that paid by most of the people. It is due to the fact that the mining of gold requires a lot of workforce and economy. Most of the gold mining operation is carried out by spraying cyanide salt on the pile of crushed rocks. This solution drains off the rock piles, and gold is left. The solution of cyanide is drained into the water resources, soils, and thereby harm the living organisms of the area. The gold mining industries had to manage the safety of environment also. It increases the cost of the extraction of gold. This is the reason due to which gold is sold at higher prices as compared to its real cost.
The cost that is not accounted includes water pollution in the pond, loss of plants and animals in the ponds, soil erosion, and soil pollution. Some forests are also cut down during the exploration of gold and its excavation. Therefore, the price of gold does not account for the harmful impact on the environment.

Use the attached piezometer map to make your own, clean version of the map, and indicate the elevation of the water table at all piezometer locations.
Draw equipotential lines (lines of equal water table elevation) using regular intervals – creating a contoured map of the water table.
Determine the direction of groundwater flow based on the horizontal gradient. Label the areas of recharge and discharge directly on your map.
Flow lines: Draw flow lines on your water table map. The lines should be at right angles to the equipotential lines and extend from the recharge area to the discharge area.
Hydraulic Gradient, Specific Discharge (Darcy Flux), Average Linear Velocity:
Using your water table map, estimate an average hydraulic gradient between two locations, call them locations A and B, one at the eastern-most and a second at the western-most extent of your dataset (note the north arrow on the map).
Calculate the specific discharge, q, between the two locations. For this calculation…
Calculate all the values of table 1:
Q in (L/day)
Q out (L/day)
Residence time (days)
