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 article introduces three ways to solve the problem that the salinity getting higher and higher in the Salton Sea in California. However, the lecturer disagrees with them for the following reasons.
First, the author of the article suggests that one of the options is direct removal of salt from the lake's water in special desalination facilities. Unfortunately, the lecturer questions the idea. She says that the chemical elements in the salt and other materials left behind by the desalination facilities may be toxic, and if wind spreads those toxic substances to the air, there will be health risks once people breathe them in.
Second, the article says that another possible solution is to dilute the salt level in the lake with ocean water. Nevertheless, the lecturer dispute the idea. This option requires the construction of pipelines or canals, and she think that the local government will not have sufficient resources to make it. To be more specific, the length of the pipelines or canals will be at least a hundred kilometers so that they can be connected to the ocean, and the cost of such long pipelines or canals will be significantly high. As a result, the government may not be able to afford this expensive solution.
Finally, the article mentions that another solution would be to control the lake's salinity by constructing walls to divide the lake into several sections, and the salinity would be reduced and controlled in the main largest section. However, the lecturer disagrees with the idea. She believes that the solution will not be long standing because of potential geological activities such as earthquakes. That is, once an earthquake hits the walls, they may fell down or get holes on them, which will cause the water with higher salinity in the smaller sections mixed back into the main section with controlled salinity.
