International and national authorities responsible for drinking water quality should consider
guidelines for desalination water treatment, specifying the minimum content of the relevant
elements such as calcium and magnesium and TDS. If additional research is required to establish
guidelines, authorities should promote targeted research in this field to elaborate the health
benefits. If guidelines are established for substances that should be in deminerialised water,
authorities should ensure that the guidelines also apply to uses of certain home treatment devices
and bottled waters.
