replies: text: By "this all," I think you mean Potability of backcountry water.  The two pages are related, but I can imagine two separate topic areas.  This article can discuss ways to purify the water, while the other article can describe what the important pathogens and pollutants are, where they occur, etc. --Smack (talk) 21:00, 15 June 2006 (UTC)

text: I agree, keeping these topics separate is important.  They may be related, but are different enough that whole articles could be built from each. Notary137 20:57, 13 August 2006 (UTC)

text: Oppose. As noted above, they are separate topics, but of course should be linked to each other. --Singkong2005 · talk 09:36, 6 November 2006 (UTC)

message: According to some sites, you don't actually need to boil water for extra time at higher elevation.  The current wikipedia article goes so far as to state that boiling can be ineffective at high enough altitudes, without citation.  I couldn't find any reliable sources one way or another.  Here's one site that suggests higher-elevation != longer-time:

thread_title:  Boiling time 

message: Hi guys, i've heard that some waterborne diseases are NOT, in fact, killed by boiling. Is this true? Secondly, the way I was 'purifying' my water in New Guinea was to boil it, catch the steam in a cloth, wring the moisture out of the cloth, therefore being left with clean water through steam. Was I just lucky not to end up with some tropical disease, or does this in fact work? 203.49.180.161 05:02, 21 July 2007 (UTC)
thread_title:  Question 

message: Prevention of water contamination is not a portable water purification system but this section is useful for the page, so we could delete the title and put the content in the introduction, that is: "Portable water purification systems are useful for water potabilization but there are some preventions that can avoid water pollution, for example... bury human waste 100 yards...

I guess I'd like to see a citation, only because it was a recent edit, and is pertinent to the Japan nuclear disaster.
.. and the addition of the '... is a myth' basically turns around a statement in the article.  —Preceding unsigned comment added by 70.79.146.225 (talk) 01:45, 18 March 2011 (UTC)
thread_title:  recent edit about nuclear event use's "...is a myth." 

message: I suggest that the citation [17] is not used.
The citation leads to an experiment abstract in which the bacteria Shewanella oneidensis MR-1 is able to undergo photoreactivation and continue reproducing with a second dose of UVC, UVB, and solar light.  Within the same abstract the author notes that e.coli is unable to do this.  This citation is used to in the Ultraviolet Purification section to suggest that multiple pathogens could undergo photoreactivation while the abstract does not back this claim.
Further research shows that Shewanella oneidensis is not a common bacteria in that it is able to metabolize heavy metals which would neuter other bacteria in the same manor (radical formation) that UV light would. (Source http://carcin.oxfordjournals.org/content/24/1/63)
This indicates that Shewanella oneidensis is much less prone to UV "neutering" and suggests that photoreactivation among Shewanella oneidensis could be much more of a concern than in other pathogens that could be ingested in a wilderness setting.
So I suggest that either the following statement be removed or re-written, or that a new citation be found.
"In the event that such UV-treated water containing neutered microbes is exposed to visible light (specifically, wavelengths of light over 330-500 nm) for any significant period of time, a process known as photo reactivation can take place, where the possibility for repairing the damage in the bacteria's reproduction DNA arises, potentially rendering them once more capable of reproducing and causing disease.[17] UV-treated water must therefore not be exposed to visible light for any significant period of time after UV treatment, before consumption, to avoid ingesting reactivated and dangerous microbes."

message: I've removed this chemical name from the halazone section: (4-(dichlorosulfamoyl)benzoic acid; 4-carboxy-N,N-dichlorobenzenesulfonamide; HOOC−C6H4−SO2−NCl2). Reason is that I don't think it helps the understanding of the layperson. Also we have no way of checking (no reference given). Maybe halazone should have its own Wikipedia article if it's important?
