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.
Both the reading and the lecture discuss the salinity problem in the Salton Sea in California, which means the amount of salt in the lake's water is increasing steadily. The reading believes that there are several solutions to decline the amount of salt in water, while the professor thinks those ways are not realistic and practical.
First of all, the author of the reading states that desalination can occur by pumping the lake's water into facilities. After heating the salt would be left behind, and the evaporated steam will be cooled down and returned to the lake as salt-free water. The lecturer rebuts this argument by insisting that the suggested process may create a chemical combination in water and leads to making a toxic material such as selenium. As we know selenium is dangerous for the health during breathing.
Secondly, the reading says that one solution is using the ocean water with canals or pipelines in order to decrease the salt percent of lake water because the water in
The Pacific Ocean is less salty. The lecturer contracts the reading by insisting that cost of this solution is higher than a local government can do it. high distances between ocean and lake need hundreds of kilometers of pipeline, therefore, this solution is not the practical way.
Finally, the author of the reading passage suggests that some walls can divide lakes into sections to separate the salty water and salt-free water, however, the professor mentions that there is high geological activities probability where the lake is, thus the activities like as major earthquakes may destroy the walls and the desalination process won't be a success.
