What is the percentage of salt in the Salton Sea?
Question Date: 2017-11-15
Answer 1:

The Salton Sea has a salinity of approximately 4.4% This means that the salt concentration in the Salton Sea is more than 20% higher than the salt concentration of average seawater; average seawater has a salinity of about 3.5% .

Thanks for the great question,


Answer 2:

The Salton Sea has a salt concentration of 56 grams/liter. Worded another way, it would be about 26 grams of salt (about 13 tsp) in a 16oz water bottle worth of water. For percentage, if we calculate it by volume, using the density of salt of 2.16 grams/milliliter, the Salton Sea would be 2.6% salt. If we calculate it by mass, assuming the density of seawater is 1.02 kilograms/liter, then the percentage would be 5.5%. Therefore, The Salton Sea is 2.6% salt by mass, and 5.5% salt by volume.


Answer 3:

According to the Division of Agriculture and Natural Resources at University of California, the Salton sea has 4.4% salt content. By comparison, the Pacific Ocean has 3.5% salt content.


Answer 4:

It changes - the Great Salt Lake in Utah is saltier and ranges between 50 and 270 grams per liter. The Salton Sea is shrinking and as it does so it becomes saltier.


Answer 5:

The Salton Sea has 44 parts of salt per thousand, which is 4.4%. That's saltier than the ocean, but not as salty as the Great Salt Lake.

This link Salton Sea says that the Salton Sea is beset by several serious problems. Because the Sea has no outlet, water is lost only through evaporation, leaving dissolved salts behind and gradually raising salinity. The Sea's salinity has now reached 44 parts per thousand (ppt), about 25% higher than ocean water.


Answer 6:

Salton sea salinity, which is the percentage of salt, is about 6.1%, and that amount is increasing by about 0.1% each year.

Values from a Bureau of Land Management report from this year (2017).
