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 main discussion is about three ways to reduce the salinity of an inland lake proposed in the article. However, the professor disagrees with those three ways and elaborate as follows.
The first solution is to remove the salt from the lake to reduce the salinity. But the professor states there is a health risk that has yet been mentioned. Specifically, the toxic chemical will be produced when conducting the technique to separate the salt and the water. If the wind spread the toxic chemical, it will be truly dangerous to people who live in the nearby area. Considering this potential harm to the people along with the solution, this may not be a wise way to apply.
Secondly, the professor points out that constructing pipelines to transport the ocean water to dilute the salty lake is really expensive and the local government may not have enough resources to make it happen. Especially, the nearest ocean is about 100 km away, and the expense will go even higher for such a long-distance pipeline or canal to be built. Therefore, the professor doesn't think this solution is practical.
Third, it is proposed in the article that the lake can be divided into several sections via constructing walls to keep high salinity within a smaller area. However, the professor emphasizes that this solution can only work for a short period, in that there are frequent geological activities, such as earthquakes, in the location where the lake is situated. As a result, the wall will be destroyed easily when an earthquake happens, and the salty water will mix back and the overall salinity will go high again.
In conclusion, the professor's opinion toward those three ways of decreasing salinity of the inland lake is disapproval, in that those solutions either creates unintended negative outcomes, or they are not feasible or durable to truly solve the problem.
