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 talk about ways to reduce salinity in the Salton Sea in California, which is currently facing issues related to high salinity in its water content which is harming the bird and fish population in and around the sea. The passage gives three solutions to get rid of this problem and reduce the lake's salinity, but the lecturer is unimpressed by these solutions and goes on to find holes in these solutions.
First, the passage states, that one way to reduce salinity is by directly removing the salt content from the water through special desalinization facilities. These facilities would heat the water from the sea and evaporate its water content which can later be condensed back into liquid water and would leave behind salt and other materials. However, the lecturer opposes this solution by saying that the salt left behind, along with other materials can possess harmful chemicals like selenium, which could be dangerous to humans as it would cause respiratory problems.
Second, the author claims that, since the Pacific Ocean has salinity levels that are less compared to the Salton Sea, water from the ocean can be merged with sea water through pipelines or canals which would reduce the sea’s salinity. The lecturer, in contrast, suggests that this solution is not appropriate as the government has no resources to build these pipelines and canals which are highly expensive. The nearest shoreline is about a hundred kilometers away, and to build these pipelines would be costly.
Lastly, the passage gives another solution, which was to construct walls and divide the lake into separate sections. The smaller section would contain a high level of salinity and the larger section would be controlled and the salt water would not be allowed to rise. The lecturer, conversely, suggests that this solution would not work as the lake was located in an area that has intense and active geological events like earthquakes. This would be a short-time solution as when a natural calamity, like an earthquake, would occur, these walls would collapse and the water from both sections would get mixed.
