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 reduced and the lake’s overall health would be restored.
Another possible solution id 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 would 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 revers in the area to flow into that main section of the lake.
The reading passage proposes three plans on decreasing the sanity in salton sea in California, in order to avoid the extinction of fish and birds. However, the instructor thinks that none of them is practical or realistic.
According to the instructor, even though the desalination can seperate water vapor from other solid substances, the materials that were left behind contain toxic chemicals, which may have a negtive impact on people's health once these chemicals are spreaded by wind.
The dillution of using sea water pumping through pipelines or canals is also unrealistic. The nearest seashore from the lake is over a thousand kilometers and the government does not have enough resources or money to fund such an expensive construction plan.
Third, since there are a lot of intense geological activities occuring around salton sea, the walls would be damaged once an earthquack happens. Thus, even though building walls can seperate the walls, it is can only last for a short time.
