Liquid gold and the salt that goes with it The southwestern states of the U.S have dealt with a drought issue in the recent years that in some places have left lakes void of a precious natural resource, water. Not only is this affecting the environment but this is also leaving the residents of some communities without any water for basic necessities. This issue has some governments and businesses looking into desalinization to produce fresh water as an alternative to the diminishing natural resource. Although this appears to be the quickest and most logical solution to this problem, many have debated against this due to the high costs and the negative impact on the

Communities that border oceans and seas choose these bodies of water as their primary source for desalinization. The issue with choosing the ocean as a primary source is the negative impact it will have on the marine ecosystem. Normally, desalinization plants use open sea infiltration to source their water, which is the least costly method, and most preferred, but can have a destructive effect on marine life. Heather Cooley co-authored an article on the website Pacific Institute where she stated that “organisms small enough to pass through [the intake screens], such as plankton, fish eggs, and larvae, are killed during processing of the salt water...” Although there is extensive historical use of open water systems, innovation can again prevail and change those methods to less destructive ones. Another method for seawater intake is the subsurface infiltration method. “Subsurface intakes …[draw] water… through perforated pipes buried in the seafloor. The overlying mud and sand act as a fine filter to screen out nearly all organisms.” (Weiser). This process has already been in use for a period and so far has proven to be successful. At the Florida Gulf Coast University, Tom Missimer, a geology professor was quoted by Mike Weiser for an online article for The Sacramento Bee, stating that there is a desalinization plant in Japan which has been using subsurface infiltration for 8-years without the need to clean or repair it. In the article, Mike Weiser also stated that Long Beach, California was also trying to adopt desalinization as another source of producing fresh water, but eventually abandoned it. They continued to use the seabed infiltration method for study purposes and after 8-years of continuous use, the only time maintenance was required was when a single pipe broke. This method has been proven effective and can definitely be a suitable
