Question

website #1 https://www.energy.gov/eere/desalination - basics questions: 1.) what is desalination? 2.) in the u.s. ___ % of water comes from aquifers. 3.) explain why aquifers in coastal areas cannot be used for water. 4.) besides seawater, list 2 other types of water that can be treated using desalination.

Explanation:

1. Desalination is the process of removing salt and other impurities from saline water to produce fresh - water.
2. In the U.S., the percentage of water from aquifers can vary by region. Coastal aquifers may be affected by salt - water intrusion, making them unsuitable for water supply in some cases.
3. Coastal aquifers can be contaminated by salt - water intrusion due to over - pumping, making them non - usable for water supply without treatment.
4. Brackish water (water with a salt concentration between that of fresh water and seawater) and wastewater can be treated using desalination techniques.

Answer:

1. Desalination is the process of removing salts and other impurities from saline water to obtain fresh water.
2. The percentage varies by region. Coastal aquifers may be compromised by salt - water intrusion, reducing their usability.
3. Coastal aquifers in some areas cannot be used for water supply because of salt - water intrusion, which occurs when fresh water is over - pumped and salt water infiltrates the aquifer.
4. Brackish water and wastewater.
