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 discussing solutions to reduce the level of salt in The Salton Sea in California. The author of the reading believes that there are several solutions that can be done to reduce the salt. However, the professor significantly shows her disagreement towards those solutions.
To begin with, the author suggests the direct removal of the salt from the lake by a special desalination facilities. On the other hand, the professor thinks that this idea presents many problems. If we use these facilities and after water evaporates, it leaves behind the salt and other type of chemicals such as: selenium. This chemical causes health issues if it is inhaled.
Secondly, the writer gives another solution which is diluting the salt level in the lake by using oceans water. This specific argument is challenged by the professor. She claims that this suggestion requires constructing pipelines and canals linking the lake to the Pacific Ocean which is 100km away, this would need an expensive resources that the government lacks.
Finally, the author posits that we can divide the lake into several sections by building walls. This way salinity would be allowed to increase. However, in the main and largest section, salinity would be reduced. In contrast, the lecturers rebuts this by mentioning that although this might work for sometimes but there are many geological activity in that area that would end up destroying the walls resulting in mixing of the water.
