Not likely: The difference between hard and purified water should only be the natural minerals. These minerals should not trigger an allergic reaction. Water in general would not trigger an allergy with the exception of the very, very rare case of aquagenic urticaria--or hives from water. It is not based on water temperature, salt or fresh, etc.
