Can desalination solve the water crisis?
Alternative water sources are necessary for sustainable development. Seawater desalination can provide a climate-independent source of drinking water; however, the process is perceived by some in the community as energy-intensive and environmentally damaging.
Why is desalination important in the Middle East?
In the arid Middle East, where fresh water is scarce and populations continue to grow, drinking or ‘potable’ water remains a highly prized commodity. For decades, the region has depended on the process of desalination, and the steel on which its structures rely, to deliver vital fresh water to its citizens.
What are the environmental benefits of desalination?
Energy Conservation
The distribution systems required to pump water across entire states consume enormous amounts of energy and generate a great deal of air pollution. Strategic placement of desalination plants reduces these energy costs and lessens the environmental impact of water distribution.
Is desalination good for the environment?
What are the environmental impacts of desalination? … Desalination has the potential to increase fossil fuel dependence, increase greenhouse gas emissions, and exacerbate climate change if renewable energy sources are not used for freshwater production. Desalination surface water intakes are a huge threat to marine life.
Is desalinated water good for you?
According to Prof. Yona Amitai, a pediatrician, toxicologist, and expert for public health at the Bar Ilan University in Israel, desalinated seawater is lacking four essential minerals that are vital to human health – calcium, magnesium, fluoride, and iodine.
What are the cons to desalination?
Cons of Desalination Plants

What are the negative effects of desalination?
Desalination has the potential to increase fossil fuel dependence, increase greenhouse gas emissions, and exacerbate climate change if renewable energy sources are not used for freshwater production. Desalination surface water intakes are a huge threat to marine life.
What states have desalination plants?
While most American desalination plants are used to purify less-saline “brackish water” from rivers and bays, large-scale seawater operations have begun to proliferate in California, as well as Florida and Texas. California alone has 11 municipal seawater desalination plants, with 10 more proposed.
Are there any desalination plants in the United States?
The United States currently has over 1,400 installed desalination plants with the majority being used to desalt brackish groundwater.
Is California using desalination?
California currently has 12 seawater desalination facilities in operation. The Huntington Beach proposal has the backing of Governor Gavin Newsom who said he wants to diversify the state’s water supply. But environmentalists have concerns.
