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 salton sea in California is facing a problem that the salinity has been increasing for the rapid evaporation rate. The reading passage has given three solutions while the listening part reveals the leak of them one by one.
The first option is to remove the salt directly from the lake’s water by a special desalination facility. however, the professor argues that this method is very likely to cause health problems. As the water in the desalination facilities evaporates, solid materials would be left behind, which contain toxic chemicals, such as selenium. Then, separating would allow these chemicals to be spread by wind, which may pose a threat to people’s health.
The second solution is bringing ocean water to the lake to dilute the salt level. The professor finds faults with this method by saying that this solution would be quite unrealistic in consideration that the government may not have enough money to build any pipelines or canals. Moreover, the nearest shoreline is 100 kilometers away, so the construction may cost a lot of money.
The last way is to divide the lake into several sections by building walls. The salinity in smaller sections would increase while in largest sections, by directing fresh water from small rivers, the salinity would be controlled. however, the professor refutes that this measure is just provisional, since the salton seas is located in place where the geological activities are frequent and intense. water from the smaller sections may mix back in the main section so this solution will also fail very soon.
