Here's a more complete quote,

it was a verbatim quote, you are not offering a more complete quote, you are
simply quoting more

which implies something quite different:

no, the text you quote indicates the copper was a contributing factor to the
dog's cancer, and, in fact, mentions no other known causes of cancer
regarding the dog's cancer (unless you consider the "good healthcare and a
reasonably varied diet" cited to be carcinogenic)

the point was made the dog was not given water out of a plastic garden type
(outside) hose but was given water from an inside faucet fed with water
through copper pipe and the dog got cancer


"However, my own dog had cancer and he was allways given water from the
tap in the kitchen with copper pipes. He also had good healthcare and a
reasonably varied diet. Many things in our environment can increase the
risk of cancer, but for most who develop it no single thing caused it,
instead the effect was an accumulation of many things working together.
Unfortunately there are no certainties in life, anybody regardless of
age, lifestyle and environment can get cancer."

In other words, anecdotes of single events are often not very good at
proving causality when so many other factors come into play.

again, the quoted data mentions no other known causes of cancer for the dog,
just the copper

it is abundantly clear you have not read all the previously cited
information on this issue of copper causing cancer

you are also trying to imply the data available that copper can cause cancer
is wrong

you are wrong


From the same thread on gardenweb:

"Copper has well-defined hazards. Plastic is still under investigation
and it will be a long time before the hazards are as well-known as
copper."

translation: no hazards with pvc (assuming you quote "plastic" as relevant
to, or meaning, pvc), which is what the available data says

if you can't show data to the contrary, your position to the contrary is
based on nothing, and it means nothing



google copper pipe cancer

copper pipe also causes schizophrenia in humans, as well as other
problems,
already covered in depth in this newsgroup and now available in the
google
archives

google is your friend

Well, I googled "copper pipe schizophrenia" and the first few hits
seemed to be written by extremist wingnuts, so I quickly got bored with
it. Googling simply "copper schizophrenia"

you didn't "google copper pipe cancer" (you googled "copper pipe
schizophrenia" and "copper schizophrenia"), then you compared your googlings
to "google copper pipe cancer", you are a failure at reading comprehension


revealed that in addition to
excess copper, INsufficient copper is a factor and that in some
individuals elevated copper was not a cause but an _effect_ of their
genetic predisposition (Wilson's disease).

So myself, if the water's been sitting for a few hours or more, I don't
trust ANY pipe not to leach nasties into my water,
plastic or metal.
Before I use any water for drinking or cooking, I make sure I've
flushed a toilet to clear any standing water in the lateral from the
main up to the house, then run the faucet for enough time till the
water feels cold. It's no extra effort because there's usually
something to flush in the toilet* and there's usually a dish to rinse
or some hands to wash in the sink.

all unnecessary with pvc pipe

enjoy your copper if you must, it's very unhealthy, and can cause cancer
(numerous links posted to substantiate this, research it yourself further,
no additional info will be offered since it's already here, you just haven't
read it)



*we conserve via the "yellow, let it mellow; brown, flush it down"
method except when company is there.
