>past few days Forums have been extremely slow for me with 5-10 minutes elapsing (without timeouts) when displaying Forum pages or Posting.[...]Think problem is on BPL server end.
I haven't noticed that. Unlike normal, where I go through and read everything once every day or so, the last few days I've been 'working' so I sit here and refresh the Recent Posts list and read the new posts every hour or so. Haven't notice any performance problems with BPL at all, i.e., no more than 10 seconds to load a page at any time.
Sorry for going off-topic.
The discussion is, of course, interesting. But pragmatically, I'm not going to worry about it because the chances are extremely low that I'm going to get sick with any reasonable choice in water treatment, even if there are a few unsterilized drops. My spoon is probably a larger threat. I have a fair selection of water treatment options, but the number one reason I take the UV AquaStar (3.8 oz including batteries), except in winter, is that I can drink cool fresh stream water in the mountains as I did when I was a kid carrying only a plastic cup. I dip a liter of fresh stream water, zap it, and drink it. No flavor change, no chemicals, no wait. Depending on the location and time of year I might bring something to pre-filter the water, but most of the places I hike have clear streams. Just lucky, I guess. The AquaStar fits nicely on a 1L lexan Nalgene bottle (4.7 oz), but it also works on a Nalgene Cantene (1L: 2.1 oz including redundant lid) or a MSR Hydromedary (2L bag: 2.3 oz). This also reduces my total weight by nearly a kilo, as I don't have to carry the liter of water while it's being treated, as I do with Aqua Mira. The AquaStar doesn't weigh much more than the two full bottles of Aqua Mira (3.2 oz), either. In the winter I use Aqua Mira, since my water is either being boiled, or just melted and sitting overnight for use the next day. No sense trying to keep batteries warm when the chemical taste/smell of AM is totally gone by morning.
