Interesting. I've always been advised not to get ice in my drinks in Mexico, but I didn't think that it would be giardia that would be the issue. I've read that giardia is killed by freezing temps. Can giardia really be contracted from ice?

I'd be curious to see some research on particulates on California. I suspect such research would reveal it's not much of an issue in California. California isn't prone to acid rain. I wouldn't collect snow near a road or railroad track, but otherwise I think you'd be pretty safe even at lower elevations
