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
The reading and the lecture are both about the methods to decrease the salinity level in the Salton Sea in California. The author of the reading feels that there are three ways to control the salinity level problem. The lecturer challenges the claims made by the author. She is of the opinion that the solutions in the article are not practical.
to begin with, the author argues that the desalination method would reduce the level of salinity in the lake. The article mentions that the water from the lake would be evaporated and easily separated from the salt particles. This specific argument is challenged by the lecturer. She claims that a desalination solution would cause serious problems. Additionally, she says that when the water is pumped and evaporated in the desalination process, the solids that remained are toxic chemicals such as Selenium.
secondly, the writer suggests that using ocean water would be a perfect solution to dilute the salts in the lake. The lecturer, however, rebuts this by mentioning that this method demands high resources. She elaborates on this point by bringing up the point that bringing the water from the Pacific ocean requires pipeline construction.
Finally, the author posits that the third solution is dividing the lake into many sections by walls and try to control the salinity in the large portions. In contrast, the lecturer's position is that this method will not work very long due to the intense geological activities. She notes that the walls would collapse due to the earthquake.
