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 Salton Sea salt level is increasing due to it has a bigger rate of evaporating than income water, such as rivers and rainfall. The reading suggests three possible solutions to reverse this trend and reduce the salinity of the lake. However, the professor in the lecture opposes each way and feels none of them is the solution to this problem.
The reading first solution is using facilities to remove salt from the lake to resort to the overall health of the lake. The lecturer rebuts this way because of its consequences; it is not realistic. When the water evaporates, not only the salt but also the other chemicals left behind, that some of them would be toxic and if the wind carries these particles, people who breathe this chemical will be harmed.
Secondly, the passage states that they can transform ocean water that is less salty than the lake, to lessen the salinity of the water. The professor refutes this by saying that the ocean is far from the lake, and they will need pipelines, and it will cost too much, and the local government cannot pay this much cost.
The final solution would be using walls to separate the lake into sections, and smaller parts become saltier than the major part. This solution is not practical because the land is geotically active, and there is a high chance of an earthquake. So, this way will be temporary, and if a major earthquake happens, the walls collapse, and the smaller salt parts combine with the major part.
So, the professor refuses all solutions to the reading by elaborating on these claims.
