The process of desalination removes salt from seawater using condensation methods or filtration. Which of the following is least likely to be a problem for widespread use of desalination to provide freshwater? A.
Desalination is relatively slow.

B.
To be economical, desalination plants must be built on coastlines.

C.
Desalination uses large amounts of energy.

D.
There is a shortage of seawater to use for desalination. what's the answer

First is the high cost, because it takes a lot of increasingly expensive energy to remove salt from seawater. A second problem is that pumping large volumes of seawater through pipes and using chemicals to sterilize the water and keep down algae growth kills many marine organisms and also requires large inputs of energy (and thus money) to run the pumps. A third problem is that desalination produces huge quantities of salty wastewater that must go somewhere.
