Thank you for bringing this to everyone's attention. It is a very important issue that gets overlooked.
I remember many years ago I use to purchase coffee at a mobile coffee express shop. It never occurred to me where they got their water from (it was too early in the morning anyway and I was half awake - lol). One day I saw one person roll a large plastic bin over to a garden hose. He told me this is the water that they use to make coffee/tea and he shrugged his shoulders about the garden hose. (At the time, I only knew of the bad rubber leeching into the water.) Eeeek! For obvious reasons, I never returned.
