[All] cancer and chlorinated water

[Susan Koswan]

Found this abstract:

 

Several Louisiana parishes (counties) using the Mississippi River for their
source of public drinking water have the highest mortality rates (1950-69)
in the United States for several cancers. Therefore, a case-control
mortality study on cancer of the liver, brain, pancreas, bladder, kidney,
prostate, rectum, colon, esophagus, stomach, non-Hodgkin's lymphoma,
multiple myeloma, leukemia, Hodgkin's disease, lung; breast and malignant
melanoma, from 1960 to 1975 in South Louisiana parishes grouped for
similarities in industrial characteristics, having approximately equal
exposure of the population to surface and groundwater, was conducted.
Noncancer deaths were randomly selected as controls and matched to the case
death on age, race, sex, and year and parish group of death. Water source at
death was assigned based on the residence at death and described as surface
or ground and chlorinated or nonchlorinated. A significantly increased risk
for surface, chlorinated water use was noted for rectal cancer. No risk
could be demonstrated for colon cancer. The risk noted for bladder cancer by
other investigators is not substantiated. Brain cancer risk appears to be
associated with chlorinated groundwater, but this may be industrial
confounding. Breast cancer demonstrated a slight, but significant, risk
associated with surface chlorinated water. This risk, however, might be due
to confounding of rural life style, early childbearing and large families
with nonchlorinated water found in these settings. Chlorination risk for
kidney cancer was not significant. No risk was observed in association with
surface water for other cancers of the gastrointestinal or urinary tract.
Multiple myeloma was significantly associated with a risk from ground water.

Cancer and the Grand Water Quality

 

I understand the City of Brantford pulls all its water from the Grand after
some treatment using coagulation, sedimentation, filtration and
disinfection.  This is basically the same thing as Manheim uses.  Has anyone
seen a recent study looking into the correlation between the percentage of
the population using treated Grand Water and the cases of cancer?  I think
it would be premature to blame it all on the water of the Grand.

Lulu  It is my belief, more and more, that many of the cancers that are
running rampant these days  have very strong connections to the environment
(that's why we're working so hard to draw attention to protecting the
Environment), and also to the food additives we are subjected to eating, the
additives to the soil our food is grown in ,  and the junk and meds and
pills people carelessly flush down the toilet  or down the sink:  it all
goes to the Grand which is  the  20-25%  supplier of our drinking water.
And now with  4 litre  toilets being promoted (and rewarded   $$$ for being
installed) it only follows that the concentration of all this harmful
"stuff" is getting into our bodies at an increasingly  concentrated rate.
Yes we need to conserve water for certain  but it would be interesting to
see the differences in contaminate concentration over the last 10 years with
the further concentration in lieu of dilution of the 'dirty' water .   GREN
and it's members  and others will carry on protecting what we can and
guarding our existing community wells and recharge areas, as in Doon South
etc. Ginny.

PS   Even the so called "Organic" veggies are subject to suspicion.  I've
been told  one of the largest "organic farms " in the US  is located right
beside  a very large airport.!!!   HELLO.    The so called "baby cut"
carrots are sold as organic in some sections    yet they are soaked in the
'preservative' to make them last 15-21 days   I do NOT regard that as
"Organic"  as it has these additives. I do not buy "baby cuts" and have
supported our kids in that the convenience is not worth the risk.  AMEN

The State of Evidence report just published shows the links between
environmental toxins and incidents of breast cancer. 

http://www.breastcancerfund.org/media/publications/state-of-the-evidence/

According to the public health data, communities along the Grand RIver
exhibit above the Ontario average for incidents of breast and prostate
cancers and much of this is linked to endocrine disrupting chemicals found
in pesticides, house hold products including BPA and flame retardants,
pharmaceuticals in effluent etc.
