Government’s West Nile Plan Criticized

Government leaders are looking at new ways to combat the West Nile virus. A new plan is coming in response to warnings that this year, the West Nile virus will strike harder and earlier than last year, and also that people in the Great Lakes region will have to be prepared to make some lifestyle changes. Some environmentalists and local public health authorities say the plan is too little, too late.

Government leaders are looking at new ways to combat the West Nile virus. A new plan is
coming in response to warnings that this year the West Nile virus will strike harder and earlier
than last year, and also that people in the Great Lakes region will have to be prepared to make
some lifestyle changes. Some environmentalists, and local public health authorities say the plan
is too little, too late. And as the Great Lakes Radio Consortium’s Dan Karpenchuk reports, some
victims of the virus are angry that not enough has been done until now:


(sounds of indoor golf)


About twenty golfers are using this indoor golf driving range to get their game in shape just
weeks before they’ll be able to enjoy playing outdoors.


But along with the nicer golf weather will come this year’s first assault by mosquito populations,
some of which are sure to carry the West Nile virus.


Like the general public most of these golfers have a mixed reaction to the dangers posed by West
Nile.

It was only two years ago that the West Nile Virus had been found in a few dead crows in North
America. Now it’s spread across much of the continent and it’s blamed directly for killing dozens
of people and infecting hundreds of others.


Last fall, Ontario’s medical officer of health, Colin D’Cunha, gave this statement when questioned
about the spread of West Nile.


“I don’t view this as cause for alarm. And I have to remind people that the serious signs and
symptoms are seen in less than one percent of people who come down with West Nile virus
infection. And to put it in context remember that the flu kills about nineteen hundred Canadians
each year.”


Victims says it was that kind of comment from a health official that caused them not to be overly
worried.


Vern Thomson became infected with the virus during his daughter’s wedding rehearsal in the
backyard of his Mississaugua home, just west of Toronto.


His wife Huguette says within days he was paralyzed and almost died. She says there wasn’t
enough warning about what West Nile could do.


“We knew there were a couple of crows that had died and I mean we knew that West Nile virus
was coming. But unfortunately we trusted our elected officials to inform us how near it was. I
mean, just because a couple of crows had died. Of course we didn’t pay that much attention to it.”


Her husband still has not fully recovered from the virus.


Tropical disease experts also raised alarms about the dangers of West Nile. Some say the Ontario
government played down the threat last year and kept crucial information out of the public
domain.


According to official Ontario government data, there were 374 West Nile cases in the province
last year. But some experts say that number was at least one thousand.


Recently Ontario announced a seven-point plan to fight the spread of West Nile virus. It includes
more surveillance, a public education campaign, mosquito controls, and more money for research.


But when the province’s health minister, Tony Clement, and the chief medical officer, Colin
D’Cunha, attended the news conference to unveil the plan, they ran into an angry Huguette
Thompson.


“I want to tell you I was in the hospital sitting next to my husband that was dying of West Nile
virus and I was so appalled by your comments doctor.”


“Well Ma’am, I want to assure you that Dr. D’Cunha…”


“I am telling you exactly that people did not take this seriously because of your comments.”


“Ma’am I want to assure you that whenever we were approached, our actions and our commentary
were to take this seriously, there is no question.”


“You’re too late with your plan.”


But health minister Tony Clement insists there was no attempt to downplay the seriousness of the
virus.


“We made it clear that everyone who does not protect themselves is taking a risk, and it is our
intention this year, as we look ahead, now that we have more information, now that we have the
experience of last year, to move ahead with our seven-point plan, and to make sure that Ontarians
are as protected as anyone else in North America.”


But complaints also came from local medical officers, who say they’re disappointed with the
amount of money the province has put into the plan.


Environmentalists are also disappointed.


Katrina Miller is with the Toronto Environmental Alliance.


“I think that the response to this point has been this kind of immediate, hurry-up crisis
management response instead of a long term plan to deal with a disease that we know is here to
stay. We need permanent measures of control, not toxic measures of control that we have to keep
applying. If we used a larvacide, if we use adulticides, we have to keep putting them out there,
and we don’t know how effective they’re going to be.”


Tropical disease experts are now warning people to brace for this year’s onslaught of West Nile
virus. They say it will come earlier and hit harder this spring.


They say birds dying of the virus in April or early May will greatly increase the risk of it
spreading across the continent, infecting tens of thousands of people.

Electrical Charges Zap Pollution

One of the biggest challenges facing Great Lakes water quality comes from polluted harbors. Scores of underwater sites have been identified, but cleanup has been painfully slow. Now, some people are taking a new approach – they’re using an electrical charge to clean up pollutants. It’s the first test in this country of the system. Supporters say it’s cheaper and faster than conventional methods. The Great Lakes Radio Consortium’s Bob Kelleher reports:

One of the biggest challenges facing Great Lakes water quality comes from
polluted harbors. Scores of underwater sites have been identified, but
cleanup has been painfully slow. Now, some people are taking a new
approach – they’re using an electrical charge to clean up pollutants. It’s
the first test in this country of the system. Supporters say it’s cheaper
and faster than conventional methods. The Great Lakes Radio Consortium’s
Bob Kelleher reports:


Stryker Bay is a lovely little cove alongside the St. Louis River, near Lake
Superior, in Duluth, Minnesota. It’s a gentle water with ducks in the
summer; and a shady hiking path along the shore.


Tim Leland lives along the shore. From his home, he sees waterfowl, and
fouled water.


“Stryker Bay is a shallow bay. It’s six foot at the most of water.
But there’s a silt that’s underneath it, and all this tar and stuff that’s
coming up. Summertime there we do have a lot of oil that makes the surface
there.”


The bottom of Stryker Bay is a biological time bomb. Under the sand, are
pools of oily stuff – that experts call polynuclear aromatic-hydrocarbons,
or PAH’s. For nearly a century, Stryker Bay was an industrial sewer. PAH’s
were first identified under the bay in the 1970’s. That tar like stuff is
still there. There’s not enough money and little agreement how to get rid
of it.


But what if you could make pollution go away by throwing a switch? That’s
essentially what a German based company promises. And U.S. officials are
listening. The first underwater test in the United States of
Electrochemical-GeoOxidation treatment is underway in Duluth. And early
results show promise. It’s a simple concept, according to Ken Whittle with
Electro Petroleum Inc., who describes the process underway behind him in a
pair of water-filled pits.


“It’s a pretty simple kind of thing. If you want to look at it;
if you have a battery charger at home, you plug the battery charger in, you
take the two leads and you connect them to the terminals on a battery. Well,
that’s pretty analogous to what’s going on here.”


Each pit is filled with polluted mud and covered with water. Metal pipes
are sunken into the muck. In one pit, a carefully controlled electrical
charge pushes electrons through the sediment between the pipes. It’s
supposed to break the electron bonds of dangerous molecules; like PAH’s.
What’s left is harmless – like carbon and water.


The test is financed by the Environmental Protection Agency and the U.S. Army
Corps of Engineers: the agency responsible for dredging shipping lanes.
Dealing with polluted sediment is a huge expense, according to Army Corps
researcher Tommy Myers.


“It’s a real big problem for us to dispose of that material. We
can’t put it back into the water. And, typically, we confine it in what we
call a confined disposal facility, and just store the material into
perpetuity and let it break down by natural processes, if it will.”


Officials would rather destroy pollutants than store them, but conventional
methods are expensive, smelly, and noisy. And they all require dredging,
and that’s expensive.


“In this particular technology, it wouldn’t necessarily require
dredging. There’s very little noise or gaseous emissions associated with
it. The main thing is it could be applied in situ; that means in the water,
without having to dredge.”


Proponents say Electrochemical-GeoOxidation is a bargain. Pollution
officials say conventional methods might cost as much as 200 dollars to
clean up a single cubic yard of sediment from Stryker Bay. But, according
to David Bowman with the Army Corps of Engineers in Detroit, electrical
cleanup might cost a quarter of that.


“Our goal with this project was to find a technology that would
work for around one hundred dollars per cubic yard. The vendor talked about
that they might be able to treat material for around forty five to fifty
dollars per cubic yard at Duluth Harbor.”


And the contractor claims the process works fast. A typical site can be
cleaned in just a few months. It’s also supposed to work on metals, like
mercury, which attach to the electrodes, which can then be disposed of in a
hazardous waste facility.


In the Duluth test, PAH’s have decreased by forty five percent in about a
month. That’s promising, although far from conclusive. The process
won’t get every molecule, but it’s intended to reduce contaminants below
dangerous levels.


Tests began in Duluth this summer, but results are several months away.
