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.
Both the reading and the lecture discuss the possibility of decreasing of salt from the Salton Sea. The author believes that there are three ways by which it will be possible to remove salt from the lake. On the other hand, the professor rejects those ways by saying that the solutions provided by the article are not realistic and practical.
Firstly, the article asserts that by desalination it will be practical to reduce the sals levels. The lecturer, on the contrary, casts doubt on this method by saying that this way causes serious problems. He says that in desalination water should be evaporated. Consequently, some chemicals leave behind that are risky for health because these chemicals include selenium which is harmful to people. Moreover, if a wind blows and spreads this chemical to the city, it will harm people because it is so dangerous for people who will breathe those poisonous chemicals.
Secondly, the reading points out that by transferring the water of the Pacific Ocean into this lake, the salt level will be decreased. The speaker, nonetheless, rejects the possibility of this method. He explains that this method needs to construct a pipeline and channel which is very expensive. Moreover, the government has not enough source to pay this amount of money. In addition, there is 1000 kilometer from the Pacific Ocean to the lake that undoubtedly will increase building pipeline and channel over such distance.
Finally, the article contends that by constructing walls over the lake and dividing it into several sections, it will be possible to reduce salinity. The professor, on the contrary, refutes this method by saying that it will not effective for a long time. To support his reason he says that the region on which the lake is located in a frequently geological active region. In other words, there are a quite a few strong earthquakes which are happening in that region. Therefore, this strong earthquake will destroy and separate the walls and the water in small sections will be mixed with large sections.
