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 methods for decreasing salinity level in a local salty lake in America. The author is of the opinion that there is some practical solutions to solve this issue and provides three reasons for support. On the other hand, the professor states that it would be great if this situation will be solved but the author’s solutions are unrealistic and unpractical by refuting each solution.
First the reading claims that they can transfer the lake’s water in to huge tankers and evaporate it so the salt will be separate from water. However, the lecturer says that this action presents serious problems for people and environment. For instance if stored water in facilities evaporated then the solid material in the water will remain. Moreover, some of them maybe toxic like Selenium components. If this solid material will be exposed in the air it will harm people through breathing.
Second, the author states that they can add ocean water to the lake since the ocean water is less salty. Conversely, the lecturer contends that bringing ocean water requires a lot pipelines and this equipment are really expensive and government will not able to afford them. Owing to the fact that the local government did not have enough financial resources to build the pipelines. In addition bringing this equipment to long distances is very expensive too.
Third, the article suggests that they can build the walls and divide the lake into the sections asserted by salinity level. On the contrary, the professor asserts that this solution is unlikely to work. Owing to the fact that sometimes earth activities such as earthquicks bring collapse in the mentioned walls and cracked them and water in haigh salinity will be resolved in the water in low salinity and fail the process.
