Caring for humidor/cigars in Afghanistan

Was gifted a humidor from a buddy out here, it's around a 50 ct. I have two Boveda 84% seasoning packs that I will use and I would like to use distilled water after the process in complete. Problem is, I can't find any distilled water here and wanted to know if placing a shot glass on "drinking water" would have any ill-effects on my sticks. Thanks for any input...
