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 reading and the lecture are both about the Salton sea in California.While the author of the article presents three solutions to reverse the trend of the threatening lake, the lecturer disputes the arguments made in the passage.His position is that none of the three solutions are practical.
To begin with, the reading passage states that removing salt through the use of desalination equipment might be effective since evaporation of water to steam leaves behind salt and other materials.The article mentions that the steam get cooled and returned to lake as salt free water.This specific argument is challenged by the lecturer.Her position is that even though salt levels reduces , it will also present some problems because the water pumped out through desalination leave behind solid materials , which are salt and chemicals. Additionally, she mentions that these materials contain selenium that is harmful to human health when inhaled.
Secondly, the author states that diluting the salt level with water from the ocean reduces salinity because the ocean water is lesser when compared to water from the lake.The lecturer, however, asserts that although reduction of saline is important, this would eventually require the construction of pipes and canals, which the government might not be able to fund.Also, she expresses that the constructions is likely to take place in a far distance.Therefore pipes and canal are somewhat expensive over long distances.
Finally, the author puts forth the idea that building walls to divide the lakes into several parts reduces salinity in the main and largest sections .The lecturer disagrees.He believes that dividing them is unlikely to be effective for a longer period because salts are located where geological disasters such as earthquakes occur and these would damage the wall in short time.Also, he claims that water from high salinity will mix with the one from low salinity.
