I'm not a fan of galvanized water bowls, not because of the rust concerns after the gavanization is eaten away (either by wear or because of a reaction with the water chemistry - possibly aggravated by the addition of either vinegar or sats - such as an electrolyte addition) and it begins to leak, but rather because the zinc from the galvanization is of greater risk.
Lead levels in modern galvanization are pretty low - more likely to affecvt someone who spends a lifetime eating chickens who drink from those sources than the chickens themselves - and even then, chances are pretty low.
I use plastics. [queue the onslaught of "plastic bad!" people] Ultimately, everything will kill you. Doing nothing will to. Best you can do is check the table odds, and either find another table or rolls your dice and takes your chances.
