Persuasive Essay On Desalination

Overall, California should pass laws to manage the misuse of aquifers to be able to get the drought situation under control. This four year drought should have created some laws by the California government after this long. The citizens are suffering and need water, and the only way they’re going to get it is by California creating

“Israel now gets 55 percent of its domestic water from desalination, and that has helped to turn one of the world’s driest countries into the unlikeliest of water giants.” (Jacobsen) Desalination is not a new idea it has been around for along time as far back as Aristotle in the 4th century and re emerging again the 1800s. Desalination is probably not going to be the magic solution to California 's drought problem at least not completely after all even the world’s biggest desal plants are only supplemental. The plants tend to not make enough water to support an entire population. Israel 's desal plant provide enough water for 2.8 million people, but California 's population is five times as bigger than israel 's and our agricultural industry is about thirty two times bigger. It can also be twice as expensive as treating other water sources due to having to heat the water. And there is also the problem of what to do with the leftover water or brine. Apparently you can’t just dump it back into the ocean as it could cause death to the nearby sea creatures due to it being too salty.

However, due to the long lasting drought in California we should heavily consider this method of producing clean water. In other parts of the world such as China, India, Australia, Spain and more they have been able to produce nearly fourteen billion gallons of drinking water through this process. The largest desalination plant in the world is located in Saudi Arabia and produces two hundred and seventy three million gallons of drinking water per day. If the United States is able to perfect this, it could fix the situation. Amanda Little does an excellent job of sharing a wide array of perspectives of desalination in her article “Can Desalination Counter The Drought”. For instance she describes the discusses the standpoint of the executive director of the California Coast keeper Alliance, Sara Aminzadeh, as she argues, “It’s just not a good option from a cost and energy standpoint.” She goes on to say, “Desalination may seem like a panacea, but it’s the worst deal out there.” Although this method may not be cost or energy efficient, this may be the only plausible method of producing clean water. As seen in Saudi Arabia this is an efficient form of creating clean water and due to the lack of resources, this may be California’s last

With the Pacific Ocean lining the California coast line some may ask why can’t sea water be filtered and used as a source of free water. This is actually an alternative that has been researched and even put into use in places such as the Netherlands, Aruba, the Middle East and even right here in the U.S. This process is called desalinating seawater. Saltwater in its pure form cannot be used for drinking water and is deadly to plants, however if it goes through the process of desalinating it can be used. With California desperate for water Carlsbad, California decided to construct a desalinating plant. An article on NBCNEWS website states that the plant can produce “50 million gallons of freshwater a day from the sea and pour it into a water system that serves 3.1 million people”

Desalination technology converts the tons of seawater that cover’s California’s coast into drinkable water. This process, though expensive and difficult, would provide California with an endless supply of water. The ocean is a huge part of the California lifestyle, and it could become a huge source of their water supply too. The Groundwater Replenishment System recycles water to be used again. It takes in about seventy million gallons of waste water a day and puts it through a cleaning and purifying process, that then makes this water safe enough to drink. Many people may not be comfortable with drinking recycled water, but this water could be put to use in landscaping and farming, adding seventy million extra gallons a day. The desalination process may be a bit far fetched for now, but using a water recycling program is completely feasible and would be a huge help in reducing California’s use of water. (only its not reducing, its just providing them with more water to use yknow? how should I phrase that?)

3. Water is a precious natural resource in Florida and it is said that supplies are dwindling. Desalinization (removing salt from) ocean water has been recommended as a solution to the problem. Why shouldn’t we drink salt water? Explain.

California can meet their water needs by using this precious resource much more efficiently than they are presently doing. California has been raising sustainable awareness by adding bulb-lit freeway signs every 10 miles along California Interstate 5 that say “Serious drought, help save water”, they have also printed placards that are posted in sparsely blooming almond and cherry groves, asparagus fields, and mile upon mile of empty dry cracked or tilled earth that warn people to use less water. As California continues to grow, this puts more pressure on their limited water supplies. California needs to figure out a way to manage their groundwater basins to secure the future of agriculture life.

According to David Sedlak, we have made large progress in seawater desalination for the past 2 decades. The largest seawater desalination plant in the Western Hemisphere that is built north of San Diego uses half of the energy use than Santa Barbara 25 years ago. One reason why Sea Water is a good way to save more groundwater because we do not have a lot of water, but lots of oil. Also seawater desalination is not always good, there is a negative side. It is energy intensive; that means that it will cause a lot more climate change, but that is the only negative thing David Sadlak had mentioned about seawater desalination; but so far the new seawater desalination plant uses half the energy it used to. This would help California because it would lower the amount of water that is pumped from the ground, therefore, seawater desalination is a possible solution for conserving more

Since the discovery that desalination could provide humans in California with clean potable water from the ocean could be very effective, it

Desalination is basically the procedure of separating excess sodium chloride, minerals and impurities from sea and ocean water to make it usable for irrigation and human consumption. It has been touted to rid the world of its current water problems for nearly 5 decades now, during this period huge strides have been made in the desalination technology. These advances have made it possible to venture into desalination as the long term option to the water problem in many parts of the world. It is seen as long term since the ocean is not going anywhere anytime soon as compared to lakes and rivers that have been going dry seasonally. The state of California is not new to the water shortage problem; as stated above tit has been a witness to previous droughts. It is therefore time to consider a long term solution to this problem.

Unfortunately, the water that is found in the ocean is not completely useable. The water has to undergo various processes before it can be safely used either commercially or for personal use. According to Science for a Changing World, “only 2.5% of Earth’s water is freshwater” and of that 2.5%, “only a little more than 1.2% of all freshwater is surface water.” That means that the rest of the Earth’s freshwater must be either in the form of glaciers and ice caps or ground-water; which would require some financial investment first to convert into potable water before individuals can use it. Moreover, the same idea applies to ocean water which would require desalination plants to convert the water. In Carlsbad, “a 1 billion [dollar desalination] plant is being built (...) [in] California to provide about seven percent of the drinking water needs for the San Diego region” (Bienkowski). With a cost of one billion dollars to cover approximately only seven percent of water needs in a region, it certainly not an efficient method to pursue, adding the fact that energy consumption would be costly through this production as

With the water crisis being seen around the world, even right here in the United States, we need to explore other options to supply fresh water to the residents. One State, in particular, that raises concern is the state of California. An alternative method to supply water to residents could be the process of desalination. Desalination is when fresh water is made by using either seawater or brackish and eliminating the minerals and salts as a way to make the water safe for human and agriculture uses ( Kesieme et al., 2013). In recent years, we have seen an increase the in the number of desalination plants around the United States (fig 1). However, is the process of desalination the answer for the water crisis going on in California? As a

If residents and corporations throughout the United States continue to frivolously waste water and refuse to make painless changes and upgrades around their homes, it will continue to increase in cost to people across the United States. For example, as a result of the water shortage crisis currently afflicting the southwestern United States, the city of San Diego, California, is currently constructing a desalination plant, located in Carlsbad, California. The idea of a desalination plant is to collect undrinkable saltwater from the ocean and, using reverse osmosis and other filtering techniques, remove the salt to produce clean, potable water (Barnett). However, there are many downsides to relying on desalination practices to provide for a city the size of San Diego. First and foremost, it is considerably more expensive to produce clean drinking water from saltwater as opposed to using regular surface water or groundwater. The act of filtering the water alone can be twice as expensive as traditional filtration methods. In addition, desalination plants consume much more energy than traditional treatment plants, mostly due to the fact that the filtration methods are much more involved. Desalination consumes twice as much power as recycled plants, and four times as much as pumping groundwater (Newell, Roohk and Reardon). For example, the Carlsbad plant alone will require the same amount of electricity as is used to power 125,000 homes in California. However, the biggest

A desalination plant is a possible alternative to California’s need of consumable water. There is a course cons against desalination mainly affecting the marine environment for leaving highly concentrated saline water behind through the process but we should not fear it as it is a long term solution we cannot toss aside. Kerry Cavanaugh from Los Angeles Times mentions, “2,000 an acre foot, compared to about $1,000 an acre foot for imported water” (par. 3). This means that production of water through this process is cost efficient and seems rather illogical to spend more money into producing water; instead of importing it from another major source. The process cost is not a major step forward, but the idea of reaching out to import water is rather absurd. California is an arid state; we are the ones responsible for turning it into a paradise. In order to maintain it that way a method to lower the cost of desalination can be propose as solution. The thought

Desalination is one of the more popular options being considered to attempt to terminate the drought. Desalination is a process through which salt water is pumped from the ocean in to a treatment facility, and then the salt is extracted to make it possible to be used domestically. This is a long drawn out process, which involves seven different steps. The steps of desalination include the
