Don't worry about the ice; there are only a couple of ice plants on the island, and they use purified water.
I have seen this comment several times. I suspect it may be terminology used ther (Coz) versus the Rocky Mountains, as evidenced by my use of "storm" being interperted as "hurricane". :11: But, I do know that the Hotle Cozumel & Resorts has several ice machines connected to their "plumbing".
I didn't research it, but I do suspect that it is the same plumbing lines that run into the rooms. Here, we call that "tap" water. These were ice making machines, that is, they froze the water into ice inside the machine. They did not store "premade" ice.
I have also noticed these "Ice making machines" in some of the bars and at least one restraurant. If I had read this thread before I went there last week, I would have paid closer attention to how many actually had "ice making machines" hooked to plumbing (tap water). I know for sure they were not filling these machines with 5 gallon bottled water. :no
Note that I am also not saying that these establishments may or may not have had some sort of filtering or purification system on the water line. From the little I have read, many places do. But the condition and maintenance of these purification systems is questionalbe, and therefore the water that comes out (or so I have read - I have not personally performed any water sample tests).
Given the above, and the questionableness of the water entering these "ice making machines" I think the statement above is misleading. Or is it just different terminology?
