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 presents three possible solutions to reduce salt level of lake. However, lecture refutes these mentioned solutions by presenting their drawbacks.
First of all, the author states that lake water can be made free from salt in special desalination facilities. In these facilities water is evaporated by heating and salt with other materials are left behind. While, lecturer says that surely it will remove salt but the collected salt and materials can cause serious health issues. Selenium is also present in it which can rise breath problems among local people. Thus, lecture rejects this solution.
Secondly, the passage argues on another possible solution that Pacific Ocean has much less salt level in its water as compared to lake. Thus, by adding this water to lake, we can reduce salinity of lake. Whereas, lecturer position on this point is that Ocean is 100Km away from lake which is a great distance and local government will not be able to bear its expenses.
Lastly, reading points out that lake's salinity can be controlled by dividing lake into sections with the help of walls. Salt level will be allowed in smaller section, while largest section will be in control for freshwater. In contrast, lecture opposes this opinion by claiming that this area may suffer from natural disasters like earthquake. The geological location of lake is highly under threat of frequent earthquakes. So, these walls will fall down by these activities. In this way, reading and lecture presents opposite views on this matter.
