They mention visual checks for dead animals, and bacterial tests. But what about checks for heavy metals? Viruses? Radioactivity? (My understanding is that viruses are frequently durable to temperature changes because, unlike bacteria, they don't have a cell wall that will get damaged when frozen)
This seems like a naturalistic fallacy to assume random ice you find is safe to drink...
- magicalhippo 2y agoHere[1] is what the gov't says on the topic. Mostly stay way from water that's near farmland and after heavy rainfall. Apart from that it's quite safe here. As for radioactivity, AFAIK the primary source would be radon from granite and similar rocks. It shouldn't be a problem for a lake, though can be a concern if you have a well[2].

- magicalhippo 2y agoTrue, however the farmland-proximity advice is primarily due to bacteria from natural fertilizers (ie cow dung etc), and those bacteria wouldn't survive freezing. That said, the virus concern is probably not invalid, so I'd get my ice cubes from somewhere with a less exciting story.

- burkaman 2y agoOften they didn't.
- ahmeneeroe-v2 2y agoWorse than "often". In my country nearly every one of my ancestors is dead. Only my parents and some of their parents have survived.
