Is it permissible for me to take Zamzam water left at the airport, which might be spoiled if not disposed of?

Water forgotten at the airport: Either it belongs to luggage registered in its owner's name, in which case one awaits the owner's return or sells it and donates the proceeds if that is not possible. Or it does not belong to luggage and has no data registered on it, in which case it falls under the ruling of trivial lost property (al-luqaṭah al-ḥaqīrah), and it is permissible for workers or travelers to benefit from it.
