שאלה | The energy demand for desalinating saline groundwater is:

The energy demand for desalinating saline groundwater is:

		lower than the energy demand for desalinating seawater mainly because groundwater’s salinity is lower.
		higher than the energy demand for desalinating seawater mainly because groundwater is deeper; thus, its pumping requires more energy than pumping seawater.
		similar to the energy demand for desalinating seawater since saline groundwater originates from seawater, so they essentially share the same water source.
		lower than the energy demand for desalinating seawater mainly because groundwater has a more stable temperature.
