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 article offered three seemingly possible solutions to cope with the inland lake's salinity in California. However, the lecture cast doubts on it.
First, the article proposed that through using pump to remove the water, extract the salt, and bring salt-free water back to the lake could be a practical solution. Nevertheless, the lecturer pointed that the material within the salt may including toxic chemicals that could evaporate into the air and cause people's health problems.
Secondly, the article mentioned to dilute water through pouring ocean water into the lake. However, the ocean is far from the place where the lake located, the local government may not have enough funding for building canals or pipelines. Thus the lecture sees the solution as not practical.
Lastly, by separating the lake into different sections may be realistic. While the lecturer claimed that there has earth quakes that may destroy the artificial walls, the dividing section solution may lead to a total failure. In sum, the lecture denoted all the reasons why the article's solutions may not solve the salinity.
