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 the 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 passage and the lecturer both talk about the several ways we could reduce the salinity of the lake water. The author mentions few methods by which we can achieve this, while the lecturer casts doubts on those methods.
Firstly, according to the passage, we can reduce the amount of salt from the lake water by passing it through a special desalination facilities, where water will be evaporated and salt along with other materials will be left behind. However, the lecturer challenges this process by stating that along with salt, several other toxic chemicals such as salimne will also be left behind. These toxic chemicals can be easily spread from the desalination facilities which can be harmful to nearby living beings.
Secondly, the text suggests that we should mix the lake water with the ocean water since the ocean water has less salt than the lake water therefore, it will dilute the lake water. However, the lecturer disputes this argument by stating that we would require pipelines for implementing this method which are very expensive and the local government do not have funds for it.
Thirdly, the author believes that we could construct walls to divide the lake water into different sections where in the water in the smaller salinity would be allowed to increase and in larger section it will be controlled. However, the lecturer asserts that these walls can easily be destroyed by intense geological activity such as earthquakes which can cause the lake water and the occean water to mix up.
