[pct-l] water purification cross-contamination

[robo hiker]

you're more thorough than i've ever been with a filter, or water . me?, hands wet, wash face, wet head, wrap hoses up together and drink.
i've had giardia 3 times, central and south america, and asia. too many meals in the market places where they wash all the dishes in one bucket and wipe them with the same rag. i'll be more careful out west where the water i'm filtering is coming from the cow upstream! :-D> From: AsABat at 4Jeffrey.Net> To: pct-l at backcountry.net> Date: Sun, 9 Mar 2008 12:52:11 -0700> Subject: Re: [pct-l] water purification cross-contamination> > For example, with the MSR MiniWorks filter, there's a long(ish) hose> that goes in the water source, and a threaded outlet that fits a Nalgene> bottle, with a lid to cover the outlet.
