ok. yeah. you got me.
Using AquaStar or SteriPen UV-C units, you wait approx. 45-90 seconds depending upon the recommended volume of water being treated. larger volumes would require multiple dosing, so, a bit longer.
what i meant, and should have been clearer, both in my prev. post and the prev. paragraph of this post (tryin' to keep these posts short), is that after the 45-90 sec. dosing period, you can drink immediately.
of course you could also go the solar UV route and wait the ~6hr dosing time. but...that is another subject.
