Also, if she is on a meal plan, the soda fountain dispenser usually has a "water" lever/button to dispense water for free. Ditto in fast food courts, etc.
A solution for nasty tasting water from fountains:

Filter and bottle in one. They sell two filters, one suitable for most domestic water and one suitable for international travel to places with dubious water.
I bought mine from REI and highly recommend it. Many retailers sell them.
Brita, Camelback and others make water bottles with bilters built in as well, though their filters are not as powerful as the Grayl. But for man situations (especially if it is just taste one is concerned with) they would work well.
A caution: the Brita soft-side filter bottles we got all leaked. The hardside ones apparently are much less likely to leak, though I have not tried one myself.
