ELI5: Why does melted ice taste different than regular water?

When I drink water with ice in it, the taste changes when the ice melts. Why is this?

The water you get from your fridge is pulled straight from your plumbing, and doesn't have time to absorb taste from the plastic and refrigerant in your appliance. When your fridge stores the water and freezes it however, not only does it absorb material from the plastic that it's frozen into, but each time you open your fridge, the air is cooled, and whatever enters the fridge settles onto the things inside after you close it. The cold surface of your ice attracts moisture settling in the air, so when you melt the icecube and drink it, you're getting the same water, except it's accumulated additional material that it's been sitting out in your fridge, and that can be enough to alter the taste of the water as a result.
