My Spouse does not have access to drinkable water at work. Signs at work read "do not drink". Can we deduct store bought bottled water from our taxes next year?

Signs at work on the water fountain and sinks read "hand wash only, do not drink"  He works outdoors in the hot sun at this location daily.  We buy packs of bottled water, that he can drink.  Next year, can we claim that water (with receipt proof) or get a deduction on all these packs of water?
The facility is not planning to get a working water dispenser installed anytime in the near future.
