One drawback of desalination is the associated with the process. a. expense b. technology c. water pollution d. reverse osmosis the answer is a

The correct answer is C. water pollution. Many chemicals such as chlorine or acids must be put in before the process of desalination can begin. The chemicals are later released because they have no further purpose and cause harm to the environment. When plants are using the desalination process a by product called brine is produced. The brine can drastically change the salinity of the source of water. Any pollution to water can harm both marine life and humans whether through food, swimming, or drinking.

The answer is C. Hope this helps.
