The Salton Sea in California is actually a salty inland lake. The level of salt in the lake's water—what scientists call its salinity—has been increasing steadily for years because the lake's water is evaporating faster than it is being replaced by rainfall or rivers. If the trend continues, the lake's water will soon become so salty that the lake will be unable to support fish and bird populations. The lake would then become essentially a dead zone. Fortunately, there are several ways to reverse the trend that is threatening the lake's health.
One option is direct removal of salt from the lake's water in special desalination facilities. Water from the lake would be pumped into the facilities and heated. This would cause the water to evaporate into steam, while salt and other materials dissolved in the water would be left behind. The steam would then be cooled down and returned to the lake as salt-free water. Gradually, the high salt levels would be reduced and the lake’s overall health would be restored.
Another possible solution is to dilute the salt level in the lake with water from the ocean. Since water in the Pacific Ocean is 20 percent less salty than water in the lake, bringing ocean water into the lake would decrease the lake’s salinity. The ocean water could be delivered through pipelines or canals.
Yet another solution would be to control the lake's salinity by constructing walls to divide the lake into several sections. In the smaller sections, salinity would be allowed to increase. However, in the main and largest section, salinity would be reduced and controlled by, among other things, directing all the freshwater from small rivers in the area to flow into that main section of the lake.
In this set of materials, the reading passage states that the Salton See in California encounters a major problem. The level of salt is increasing for years for different reasons. The passage introduce three solutions to solve this issue. However, the lecturer finds all the solution dubious and impossible to to happen. She provides some evidence to refute them all.
First of all, the author of the passage claims that direct removal of salt through evaporation mechanism can make the water pure. In contrast, the professor argues that remaining salt is contaminated by some other poisonous chemicals which are dangerous for health. Even breathing the air of that chemicals can cause serious problems. So, this is not a safe solution.
Furthermore, it is mentioned in the reading passage that dilution of the salt in the lake is another way to reduce the level of salt. It proposes to use ocean water for this purpose. On the contrary, the lecturer contends that oceans are really far from the lake and long pipelines are needed which are too expensive. The government does not have enough resources to pay for the cost. Therefore, it is not practical at all.
Finally, the reading passage asserts that constructing walls is a definite solution. If they divide lake to a main section and some smaller sections, the main one stay clean with lower amount of salt. Conversely, the professor believes that for short while it may work but it is unlikely to help for a long period of time. Earth activities such as intense earthquakes would destroy the walls and mix all the water together. In fact, this one does not permanently solve the concern.
