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 states that the Salton sea in California has a high amount of salt or so-called salinity, and could be revived. The speaker, however, finds this idea unrealistic because of three main reasons that are presented in the following paragraphs.
To start with, the reading passage claims that removing the salt from the water of the lake by desalination equipment is an option which can reduce the salt level. On the contrary, the lecturer is of the view that taking salt out of the water seems to be dangerous. Since the solid material which remains after the water evaporation may contain toxic chemicals, and by floating in the air, people could face health problems.
Secondly, the reading passage holds the view that one option is to carry water from the Pacific ocean to the lake because it has 20 percent less salt in it. Conversely, the speaker believes this delivery requires constructing pipelines or canals. Additionally, as the lake is far from the ocean, she thinks that it is a costly solution and local governments do not have enough economical power to take care of that.
Finally, there is another solution presented by the reading passage: walls could be built and make partitions in the lake, so in the smaller section the salinity would increase, but un the main section thee salt level will stay low. The lecturer casts doubt on this idea, and indicates that the walls could be destroyed by an earthquake and the low-salt water will be mixed up with the hight level salty water again.
