PROBLEM TO BE SOLVED: To provide a method for producing water, by which water exhibits small half-vale width of 17O-nuclear magnetic resonance signal with good reproducibility. SOLUTION: In a method for producing water being used as drinking water, water for producing cosmetics and pharmaceuticals, brewing water, water for diluting a condensate of juice or the like, raw water is passed through a salt- type ion-exchange resin or a mixed bed of the salt-type and a regenerated-type ion-exchange resins so as to control the half-vale width of 17O-nuclear magnetic resonance signal of water. As the salt-form ion exchange resin, carbonic acid ion-type and/or hydrocarbonic acid ion-type anion exchange resins are preferable. As the raw water, pure water having electrical conductivity of <=10μS/cm is preferably used. |
