Thats on the low side of the recommendations,
60C, 140F is much more common.
http://www.google.com.au/search?q=Legionella+60+C

You get more hits for
http://www.google.com.au/search?q=Legionella+50+C

You cant just count the hits, you need to consider the source.

And you ****ed that up completely anyway, given that
the vast bulk of the 50C hits said that that temp is
what sees a significant problem with Legionella.

So, I continued, narrowing the chase.

No you didnt, that has the same problem, the
vast bulk of the 50C hits said that that temp is
what sees a significant problem with Legionella.

http://www.google.com/search?q=Legionella+50oC
gives a shorter list, and has some interesting links.

Nope, none that are useful on that question which
substantiate their claims with rigorous science.

None that agree with you, I take it?

Even you should be able to bull**** your way out of your
predicament better than that pathetic effort. Not one of those
recommends the use of 120F with water storage heaters.

http://www.dhmh.state.md.us/html/legionella.htm
says you are just plain wrong using rigorous science.

I see adherence to the earlier advice.

You need new glasses then.

"Legionella die rapidly at 55oC (131o F)(3 log reduction
within 1 hour), and are killed almost immediately at
temperatures over 60oC (140oF)."

Useless for your previous claim about 120F

In a continuum, or can you not hold a thought that long?

Even you should be able to bull**** your way out
of your predicament better than that pathetic effort.

immediately at 60, 1 hour at 55, 2 hours at 50,

Pity that none recommend the use of your original stupid
pig ignorant claim about 120F with storage water heaters.

not mentioned in this quote, but wait, continue further if you can.

Even you should be able to bull**** your way out
of your predicament better than that pathetic effort.

It was present in the tested systems
because they were kept below 43c.

in a hospital hot water system, legionella is able to survive and
multiply, particularly as hot water temperatures are kept relatively
low to minimize the scald risk for patients [35]. In Maryland, state
regulations for nursing homes limit temperatures at the outlet to
110oF [43oC](COMAR 10.07.02); "

Again, so much for your 120F claim.

The tested samples had Legionella because they were kept
below 110f. How does that say anything about my 120f claim?

Even someone as stupid as you should have noticed that
there isnt much difference between those two, and that the
vast bulk if not all of those hits with 50C used that as the
temperature at which legionella continues to breed, stupid.

You live somewhere that has a code that requires hotter water.

So do you very likely.

I find attributions for lower temperatures, but no code requirement.

Your problem.

So, let me look in three places that I care about
as references: nih.gov and CDC.gov as research
points, and ca.gov, because they regulate my life.

Referring to cooling towers, not DWH:

So completely irrelevant to what is being discussed, storage hot water
systems.

http://www.energy.ca.gov/2005publica...0-2005-025.PDF
"Keep cold water below 25 C (77 F) and hot water above 55 C (131 F)."

From the Centers for Disease Control, whom
I would consider to be the foremost authority.
http://iier.isciii.es/mmwr/preview/m...l/rr5210a2.htm
"The bacteria are rarely found in municipal water supplies and tend
to colonize plumbing systems and point-of-use devices. To colonize,
legionellae usually require a temperature range of 77F--108F
(25C--42.2C ) and are most commonly located in hot water systems. "

Pity about the rigorous scientific evidence cited above and in
countless other hits even you should be able to find using google.

http://www.cdc.gov/ncidod/EID/vol12no04/05-1101.htm
"Legionella colonized 60% of the hot water systems before
monochloramine ... Increased prevalence of Legionella colonization
was associated with water heater temperatures 50C ...

So much for your stupid claim about 120F

grows optimally at 35C and multiplies between 25C and 42C"

Chloramine, not chlorine, is used in public water systems in California.

Irrelevant.

Further down on the CDC page is a recommendation for health
care facilities to use a system as you described, 61c water storage,

And there might just be a reason for that recommendation, stupid.

and blending to no more than 51 for delivery.

Irrelevant to what is being discussed.

http://www.awt.org/Legionella03.pdf
seems to be an easy to read correlation of data from sources
that I would consider valuable. Page 12 speaks of DWH.

Pages that I've lost reference to refer to the desire
for hotter temperatures for Legionella protection,
mitigated by the more pressing need to prevent scalding.

There are other ways to avoid scalding while
continuing with 60C for the water storage temp.

I'm done now. You win.

I do indeed, you never could bull**** your way out of a wet paper bag.
