TPO 54. 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 propose three methods to reduce the salinity of the Salton Sea to protect fish and bird population. The lecturer, however, cast doubts on all of these methods.
Firstly, the reading suggests to remove salt from the water by pumping it into desalination facilities. The lecturer, concerning on the health risk brought by it, opposes this suggestion. When evaporating water by desalination facilities, toxic chemical materials would be left. They could damage people's health when they are spread by wind and breath in.
Secondly, the reading suggests to dilute the Sea by water from the ocean. On the contrary, the lecturer point out that the government cannot pay to construct the pipe. As Pacific Ocean is 100 kilometers away from the Sea, it is not affordable to construct such a long pipe.
Last but not least, the reading suggests to construct walls to separate the Sea into different areas and control the salinity of the largest areas only. The lecturer challenge this by stating that it is not a long term solution. There are frequent geographical activities around the sea, and the walls would be destroy in a major earthquake. The water from different area would then mix together.
