According to
the Centers for Disease Control and Prevention (CDC), more than
200,000 people are hospitalized and 36,000 deaths are
reported every year in the U.S. from flu-related complications.
The Water Quality & Health Council (WQ&HC), with the support
of the National Consumers League, has created a Website, http://www.waterandhealth.org/flu,
dedicated to educating the public on flu prevention.
The WQ&HC
site emphasizes the importance of yearly vaccinations, frequent
hand washing, covering your cough and other personal hygiene measures,
as well as limiting cross infection if one does become ill.
Since household surfaces such as doorknobs, counters, table tops,
handles and switches can be "hot spots" for germs, the
WQ&HC also recommends disinfecting frequently-used surfaces
with a diluted chlorine bleach solution or disinfectant wipes.
Additionally,
the site includes preparedness resources for a potential influenza
pandemic - a global infectious disease outbreak that can occur
when a flu virus new to human immune systems emerges, spreading
easily from person-to-person. The WQ&HC site has a checklist
of household items needed in the event of a flu pandemic, with necessary
items including a supply of stored food and drinking water, first
aid supplies, personal hygiene products and disinfecting chlorine
bleach.

Change Threatens Drinking Water |
|
According to
a new study from Ohio State University, coastal communities could
lose up to 50 percent more of their fresh water supplies than previously
thought as sea levels continue to rise. For the study, hydrologists
simulated how saltwater will intrude into fresh water aquifers,
based on predictions by the Intergovernmental Panel on Climate Change
(IPCC), which has concluded that within the next 100 years, sea
level could rise as much as 23 inches.
Prior to this
study, scientists assumed that, as saltwater moved inland, it would
penetrate underground only as far as it did above ground. However,
this new research shows that when saltwater and fresh water meet,
they mix in complex ways, depending on the texture of the sand along
the coastline. In some cases, a zone of mixed, or brackish, water
can extend 50 percent further inland underground than it does above
ground. Like saltwater, brackish water is not safe to drink
because it causes dehydration. According to the Untied States
Geological Survey, about half the county gets its drinking water
from groundwater.
Scientists have
used the IPCC reports to draw maps of how the world's coastlines
will change as waters rise and they have produced some of the most
striking images of the potential consequences of climate change.
Researchers would like to create similar maps that show how the
water supply could be affected, but it is not an easy task since
scientists do not know exactly where all of the world's fresh water
is located nor how much there is.

| Federal
Appeals Court Upholds EPA Water Treatment Rule |
|
The U.S.
Court of Appeals denied the city of Portland's request to be exempt
from a federal water-treatment rule that requires cities to address
cryptosporidium risks from their water supplies.
The court ruling will force Portland to erect a water treatment
plant at the remote Bull Run watershed by 2014, in order to lower
levels of cryptosporidium - a parasite which can seriously sicken
people with weak immune systems and does not exist at high levels
in Bull Run's naturally pure water.
The federal
law also makes Portland protect or further treat water once it
hits the city's five reservoirs. In order to comply with this
regulation, the city of Portland could cover the now open reservoirs,
close the reservoirs and build covered storage or add five "mini-treatment
plants" at the reservoirs. It is estimated that implementing
this rule could cost between $125 million to $350 million.
Portland, which
filed the appeal along with New York, argued that the rule was flawed
because the EPA did not sufficiently study its costs and benefits,
use the best science to make the rule or respond adequately to public
comments.

Schedules Another Total Coliform Meeting for Dec. 5 - 6, 2007 |
|
The Environmental
Protection Agency has scheduled a meeting for Dec. 5 - 6 in Washington,
DC, to discuss a federal rule on controlling microbial contaminants
in drinking water. The meeting will be the third of 10 planned
meetings under the Federal Advisory Committee Act to consider revisions
to EPA's Total Coliform Rule (TCR). Total coliforms are a group
of closely related bacteria that, while usually not harmful to humans,
can indicate a water utility distribution system's vulnerability
to more dangerous pathogens. The TCR, which was published in
1989, set both health goals and legal limits for the presence of
total coliforms in drinking water. The rule applies to all public
water systems and details the type and frequency of testing that
water systems must undertake.
Topics of discussion
at the December meeting will include: TCR rule objectives and how
the TCR relates to other Safe Drinking Water Act regulations, TCR
indicator framework, TCR implementation and compliance analysis,
potential ways to revise the TCR and an assessment of the information
on distribution system issues that may impact water quality.
