Ok, so the water stations outside are not chilled, nor are they filtered. If it doesn't have a filter light (Green/Red), then they are definitely not.
A map in the
MDE app shows you all the Bottle Fillers, but there aren't many. the One BF by Tron is chilled, but the capacity and distance from the chiller don't work
I wish they would filter the water, given all the issues with PFAS.
