Your husband is correct. The ship's drinking water is distilled
, which brings it up to "Grade B" standards of purity. The normal filtration processes used for drinking water ashore bring it up to "Grade C" standards of purity. (To obtain "Grade A" water, one must distill and then demineralize
it. For human consumption, demineralization is not necessary.)
