As mentioned in Desalting the Sea: Part 1, the Salton Sea is undergoing increasing salinization. Desalination, or “desal” for short, is a commonly proposed option to restore habitat and ecosystem health, and its role in the Salton Sea Restoration and Renewable Energy Initiative has been discussed. Part 1 explained the details of thermal distillation, and this accompanying post will introduce membrane filtration, another common desal technique. Continue reading “Desalting the Sea: Part 2”
The Salton Sea Water Incremental Funding in Time (SSWIFT) proposal is another reason to be optimistic about restoration at the Sea.  SSWIFT, which is backed by County of Riverside District Supervisor John Benoit and the Salton Sea Authority (SSA), could be a simple solution for mitigating fugitive dust while other projects that focus on wildlife preservation and energy development are established around the Sea. Continue reading “Let’s be SSWIFT about it”
So far, this blog has discussed extensively the ecological and socio-economic consequences of allowing the Salton Sea to dry up. The decline in the air quality around the Salton Sea due to exposed playa is a problem that will extend to many cities in the southwestern U.S., the economic burden of allowing the Sea to dry will be shared among all Californians, and water allocations that impact the Sea are decided by intra-state agreements. Without a doubt, the Salton Sea is a complex system that must involve not only the local communities, but also different states and even nations. An important player that has largely been left out of discussions thus far is our neighbor to the south, Mexico. Continue reading “Mexico and the Salton Sea”
Several previous posts have discussed the ecological importance of the Salton Sea, particularly its effect on migratory birds. However, the Salton Sea is also home to a much less obvious endangered species, the tiny desert pupfish. Desert pupfish, which are less than 3” long fully grown, are an unusual species due to their incredible tolerance for extreme water conditions. The desert pupfish can survive at salinities of up to 70 g/L—more than double the salt concentration of seawater. This has historically allowed the desert pupfish to live in saline lakes, rivers, and marshes throughout the deserts of California, Arizona, Colorado, Nevada, and Mexico.
Assembly Bill 965, written by Eduardo Garcia from the 56th District, amends previous legislation to increase cooperation with Mexico and allocates money to be used for watershed restoration projects along the US-Mexico border.  Specifically, AB 965 adds the Secretary of State and Consumer Services to the California-Mexico Border Relations Council as a voting member, and it allows the US EPA Region 9 to appoint a non-voting representative to the council as well. Similarly, the bill also requires the council to invite representatives from Mexico to any meetings that are held by the council. As far as resource allocation, the bill makes funds available from the California Border Environmental and Public Health Protection Fund to the California-Mexico Border Relations Council, to be used to:
“… identify and resolve environmental and public health problems that directly threaten the health or environmental quality of California residents or sensitive natural resources of the California border region, including projects related to domestic and industrial wastewater, vehicle and industrial air emissions, hazardous waste transport and disposal, human and ecological risk, and disposal of municipal solid waste.” 
Much like the Salton Sea, many inland bodies of water suffer from rising salinity, which can harm biota and prevent beneficial water use. This salinization occurs when soil, which contains salts and minerals, is mobilized from clearing natural vegetation or when fresh water is diverted for irrigation.  As irrigation water and drinking water sources become increasingly salty, different solutions become necessary to recover freshwater. Saudi Arabia is the world’s leader in desalination, which is the industrial process of removing salt from water, with 50% of the nation’s drinking water recovered from seawater.  At the Salton Sea, desalination is being explored as a part of habitat restoration efforts. Continue reading “Desalting the Sea: Part 1”
The Salton Sea has been many things to a lot of people. It has been a piece of post-apocalyptic landscape, an artist’s muse, and a lesson on water management and habitat restoration. At one point, it was a hot spot for vacations and was even one of the hottest fisheries in California. Imagine that, the Salton Sea as it is now once had enough fish in it that you could catch them without bait. Now, not so much, but that does not mean you cannot fish at the Salton Sea. There are even groups such as the Sea and Desert Interpretive Association that advocate fishing at the Salton Sea as a wholesome means of entertainment.
So the pressing question on everyone’s mind is “Can I eat fish from the Salton Sea?” More precisely, “Will eating fish from the Salton Sea kill me?”
