Desalination Plant Knowledge Assessment

San Diego faces a severe water crisis due to prolonged droughts. To address this, the region is investing in the Carlsbad desalination plant, the largest in the Western Hemisphere. This plant uses advanced reverse osmosis technology to convert seawater into freshwater, providing a reliable water source despite environmental and economic concerns. While desalination offers a partial solution, it raises questions about energy consumption and environmental impact. As California explores more desalination options, it must balance these factors with the urgent need for water.

What percentage reduction in water usage has California imposed due to the drought?

• 25%

• 30%

• 15%

• 10%

What is the significance of the Carlsbad desalination plant?

• It's the first in the world.

• It's the smallest in the Western Hemisphere.

• It's the most expensive in the world.

• It's the largest in the Western Hemisphere.

What technology is used in the Carlsbad desalination plant to convert saltwater to freshwater?

• Reverse Osmosis

How much will the average residential water bill increase due to the desalination plant?

• $15

• $5

• $2

• $10

What is a major environmental concern associated with desalination plants?

• Increased marine life

• Decreased energy consumption

• Greenhouse gas emissions

How much power does the Carlsbad plant consume daily?

• 420 megawatts

• 840 megawatts

• 1,200 megawatts

• 2,000 megawatts

What percentage of San Diego's water demand is expected to be met by desalination?

• 10%

• 5%

• 30%

• 20%

What is a suggested alternative to desalination for addressing water shortages?

• Building more dams

• Drilling more wells

• Increasing water imports

What historical event led to the shutdown of Santa Barbara's desalination plant in 1992?

• Heavy rainfall

• A financial crisis

• An earthquake

• A severe drought

What is the long-term goal for desalination in California?

• To replace all other water sources

• To be a partial solution for drought

• To export water to other states

• To eliminate the need for conservation
