Is seltzer water harmful?

No - Well, if you had enough you could drown in it :) And it is mildly acidic, so if you soaked your teeth in it, hour after hour, it could damage the enamel on your teeth. However, just drinking a glass or two - or ten - isn't going to impact ones health.

Depends on how you define 'harmful', but probably not Today, seltzer water is just carbonated water (water with high-pressure carbon dioxide to give it fizzz - like sodas). If you're worried about sodium content in seltzer - many brands also have a sodium-free version. en.wikipedia.org/wiki/Carbonated_water in 1880, selter water was made with bicarbonate of soda and salt.

I found this from a 1881 household products instruction book on how to make seltzer water. Chloride of calcium and chloride of magnesium of each 4 grs. Dissolve these in a small quantity of water, and add it to a similar solution of 8 grs.

Bicarbonate of soda, 20 grs. Common salt, and 2 grs. Of phosphate of soda.

Mix, and add a solution of 1/4 of a gr. Of sulphate of iron. Put the mixed solution into a 20-oz.

Bottle, and fill up with aerated water. But much of the Seltzer water sold is said to be nothing more than simple carbonated water. An imitation of Seltzer water is also made by putting into a stone Seltzer bottle, filled with water, 2 drs.

Bicarbonate of soda, and 2 drs. Of citrate acid in crystals, corking the bottle immediately. Soda powders are sometimes sold as Seltzer powders.
