Question

website #1 https://www.energy.gov/eere/ito/desalination - basics questions: 1.) what is desalination? the process of removing salts from water. 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 salts from saline water to make it suitable for use.
2. In the U.S., a small percentage of water comes from aquifers. Exact figures may vary by region and data - source, but aquifers are not the major source of water supply in most areas.
3. Aquifers in coastal areas cannot be used for water in some cases due to salt - water intrusion. As sea - level rises or over - pumping occurs, saltwater can seep into the aquifers, making the water too saline for use without treatment.
4. Brackish water (a mix of fresh and salt water) and wastewater (used water from domestic, industrial, etc. sources) can be treated using desalination or other water - treatment processes to make them reusable.

Answer:

1. Desalination is the process of removing salts from saline water to produce fresh water.
2. The percentage of water coming from aquifers in the U.S. can vary by region, but generally, it is a relatively small portion compared to other sources like surface water.
3. Aquifers in coastal areas cannot be used for water because of salt - water intrusion, which contaminates the fresh water in the aquifer with saltwater.
4. Brackish water and wastewater are two types of water (besides seawater) that can be treated using desalination.
