The EPA wants communities to do more to protect
drinking water from a harmful microorganism. That could mean
several changes for cities around the Great Lakes. The Great
Lakes Radio Consortium’s Chuck Quirmbach reports:


Ten years ago, a Cryptosporidium outbreak in Milwaukee led to
the deaths of more than 100 people who had weakened immune
systems. The outbreak sickened 400,000 other people.


Since that time, Milwaukee has made 100 million dollars in water treatment plant
improvements. Milwaukee waterworks superintendent Carrie Lewis
says the EPA’s plan to make all drinking water treatment
systems monitor and guard against the microbe means some
cities face new construction at their water treatment buildings.


“Because one doesn’t easily add more barriers to
organisms like Cryptosporidium without adding more physical plant
to the water treatment plants.”


Lewis expects some cities to debate the cost and benefits of the
rule package.

Billions for Great Lakes Cleanup?

The federal government could soon promise a lot more money to help clean up
the Great Lakes. Lawmakers from several states in the region are proposing a
multi-billion dollar cleanup fund. More from the Great Lakes Radio
Consortium’s Michael Leland:


Lawmakers from states bordering the Great Lakes say previous cleanup efforts have been
uncoordinated and under-funded. The region’s U.S. Senators are sponsoring
a bill that would give Great Lakes states six-billion dollars in grants during the
next ten years. A similar bill in the House offers four billion over five years.
Andy Buchsbaum heads the National Wildlife Federation office in Ann Arbor. He says the
proposals are groundbreaking.


“Until now, all too often the approach has been to slow or, if we are very lucky, to stop the
degradation of the Great Lakes. But these bills really break the mold. They give the lakes a
chance to improve, to heal, to recover.”


The Senate bill would create a regional advisory board to recommend which projects should
receive federal money. Buchsbaum predicts presidential candidates hoping to win support in the
region will back the bills. Both measures are only authorization bills. Lawmakers in future years
would have to vote to actually spend the money.

A recently published study indicates that trees in cities are growing better than trees in
rural areas downwind of the cities. The Great Lakes Radio Consortium’s Lester Graham
has more:


This study, published in the journal Nature, found that trees grown in many
different conditions grow twice as fast in the city than trees in the country. Jillian Gregg
at Cornell University is the lead author of the study. She says lots of factors affected the
trees…


“But, in the end, the most important factor was ground level ozone which was higher in
rural environments.”


Ground level ozone develops when pollution in the city stews in the sun for a while. As
the chemicals drift out of the city, ozone develops downwind in the rural areas where the
impact on the trees is greater.


“So, in the rural environments, the ozone stays around for longer so you have a longer
exposure period.”



During three growing seasons at eight sites in eleven different types of soils, the results
were the same. The city trees did much better than the trees in the country exposed to
ground level ozone longer.

Turtle Numbers Down; Trapping Banned

Many Great Lakes states are taking steps to protect turtles. There’s a big demand for turtles in
Asia and Europe. But too much trapping can damage wild turtle populations. As a result, states
are placing bans or restrictions on turtle trapping. The Great Lakes Radio Consortium’s
Dan Gunderson reports:


(sound of paddling)


Joanna Schmidt pushes a canoe into a small slough in northern Minnesota. She paddles toward a
floating rectangle of plastic pipe. The simple device is a turtle trap. It’s about four feet long with
net in the bottom and a board attached to the side.


“We put a plank on the side and they crawl up to sun themselves and they
just fall in. It’s pretty simple. No mechanics to it. They do all the work for us.”


Joanna Schmidt is a student at Minnesota State University Moorhead. She’s
part of a long-term turtle research project. Researchers want to learn
more about turtle habitat, and why there’s been a recent decline in turtle
populations.


This slough is about a quarter mile across. It lies in a hollow surrounded
by farm fields. Chest high grass and reeds line the water’s edge. Along one end, dead,
sunbleached trees stick out of the water. It’s perfect turtle habitat.


“It’s warm, a lot of food for them, not very many predators, so they like it,
especially having the dead trees with a place to hang out and sun themselves. So this is
very typical.”


Gunderson: “Any estimate of how many turtles might live in a slough this size?”


“Not just yet. That’s what we’re hoping to get to. And that’s what the DNR would
like to know.”


There are several turtles in the trap. Most have been caught before.
They’re identified by small notches in their shells. Schmidt weighs and measures
each turtle before gently setting them back in the water.


Minnesota State University Moorhead Biology professor Donna Stockrahm is
directing this research project. She says it takes years of research to get meaningful data about
turtles. They grow very slowly and they live a long time.


Stockrahm is hoping to learn about rates of turtle mortality, growth rates,
and the optimum habitat for turtles.


She’s seen a puzzling decline in turtle numbers.


“We started this in 2001 and they marked over 250 turtles. Then in 2002
the number just dropped drastically. And there seemed to be fewer turtles
around, even turtles that you see out sunning themselves on rocks and limbs and
dead tree trunks and things like that.”


Stockrahm says she doesn’t have an explanation for the decline. She’s
waiting to see if the trend continues this year.


Turtles are in demand in Europe for pets, and in Asia for
traditional medicines. More than seven million turtles are
exported from the United States each year.


Minnesota Department of Natural Resources researcher Rich Baker says
trapping is one reason turtle populations are down.


“What we’ve learned relatively recently is that especially in northern
latitudes commercial harvest really isn’t sustainable. These populations
of slowly maturing species just can’t sustain harvest of adults from the
population.”


Rich Baker says demand for turtles is driven largely by Asian and European
markets. Baker says many Asian turtle species are endangered because of
overharvest.


Those markets are turning to North America which is a particularly turtle-rich
part of the world and the upper Midwest which is a particularly
turtle-rich part of North America. Many of the states in the upper Midwest
have actually closed commercial turtle harvest completely.”


Most Great Lakes states now ban or restrict turtle trapping. Rich Baker
says Minnesota decided to phase out commercial harvest. He says about a dozen
people make a living trapping turtles. They’ll be allowed to continue.


People who like to eat turtle can still get a license to trap for personal
use. But there will be no new commercial turtle trapping licenses.
Minnesota will allow turtle farms as an alternative to harvesting wild turtles.

Insecticides to Curb West Nile Best Choice?

Some health experts and politicians are struggling with balancing the risk of West Nile virus with the perceived hazards associated with spraying insecticides to kill the mosquitoes carrying the virus. The big question is – to spray or not to spray? Last year… public health officials in many communities decided to spray pesticides on adult mosquitoes, hoping to reduce the chance of West Nile virus infection in humans. But spraying was met by a public outcry from some residents concerned about the immediate and possible long-term health effects of the chemicals. This year, some health departments have chosen to focus their control efforts on killing mosquito larvae before they hatch with chemicals that are relatively benign. Others still plan to spray.

Some health experts and politicians are struggling with balancing the
risk of West Nile virus with the perceived hazards associated with spraying
insecticides to kill the mosquitoes carrying the virus. The big question is –
to spray or not to spray? Last year… public health officials in many
communities decided to spray pesticides on adult mosquitoes, hoping to reduce
the chance of West Nile virus infection in humans. But spraying was met by a
public outcry from some residents concerned about the immediate and possible
long-term health effects of the chemicals. This year, some health departments
have chosen to focus their control efforts on killing mosquito larvae before
they hatch with chemicals that are relatively benign. Others still plan to
spray. The Great Lakes Radio Consortium’s Karen Schaefer reports:


Last year there were more than 4,000 reported cases of West Nile virus
in the United States. The virus hit some Great Lakes states especially
hard. In Ohio, in Cuyahoga County – which surrounds Cleveland – 211 cases
were confirmed and 14 people died. The County’s health district decided to
do a sero-survey, taking blood samples from about 1200 residents to
find out just how many people actually got West Nile virus without noticing
any symptoms. Assistant Administrator Terry Allen says the results were
surprising.


“We found that between four and about six and a half-percent of
residents were exposed to West Nile virus. That equates to perhaps 50 to
80,000 people in Cuyahoga County that were exposed last year.”


Allen concedes that one way of looking at those figures is to see that the
number of deaths in the infected population was extremely low. But Allen is
concerned that a new outbreak of West Nile could infect thousands of people
who weren’t exposed last year and could cause even more deaths. So he says
the county has decided to take all possible precautions – including spraying
a pesticide on adult mosquitoes in areas where human cases are reported.


“You have to put this in context. Most counties in Ohio do not
spray for mosquito control.”


That’s Barry Zucker, president of the Ohio Coalition Against the Misuse of
Pesticides. He’s one of many county residents who oppose spraying.


“What the doctors tell us and what the medical studies tell us
is that there are real and potential health consequences from pesticides –
everything from upper respiratory diseases to possible neurological damage
to possible increase in breast cancer. The bottom line is that the pesticide
spraying for adult mosquitoes does not work.”


Others have come to the same conclusion. Bill Tomko is president of the
village council of the Cleveland suburb of Chagrin Falls.

“Our concerns relative to the county board of health was they
didn’t really have any data that indicated that the spraying would do any
good. And we became quite concerned that it was being done to have the
appearance of action in order to quell the emotional response of, you
know, ‘Do something, protect me.'”


Tomko say his community is one of many in the region that have decided not
to spray.


“My first reaction is just to extrapolate from the medical
profession when you’re looking at spraying versus not spraying, first do no
harm. The better way to do it is to apply individual protection
measures and to go after the breeding of the mosquitoes themselves, which is
what we adopted to do in Chagrin Falls by adopting a larvacide program.”


Tomko says his community will pepper catch basins and areas of standing
water with a chemical briquette that kills only mosquito larvae. Combined
with a reduction of breeding sites like removing old tires, continued
surveillance, and a public information campaign about the need for personal
protection, Tomko hopes to keep residents safe from infection by West Nile
virus. Last year, no one in Chagrin Falls got sick.


But Cuyahoga County Health Director Tim Horgan says, with the high infection rate seen
last year in urban areas, he just can’t take that risk. So in addition to larvacide,
surveillance, and all the rest, he says the county will use pesticide sprays
if conditions warrant. Health Director Horgan warns that even residents on
the county’s no-spray list could see pesticide spraying in their
neighborhoods this summer.


“With the problems we had last year, we might have areas where’s
there’s a number of houses on an individual street where people would rather not be
sprayed. And then we might have a case or two of human disease right in that area. If
that happens to us this year, we’re going to notify people on the list, let them
know we’re going to be there. But I think we’re going to try to go in and
make sure that area gets sprayed and that’s very consistent with the
recommendations of the CDC.”


But even the head of the Centers for Disease Control admits there’s not
enough good scientific evidence to be sure spraying works. So while some
health districts such as Cuyahoga County and the city of Cleveland plan to
spray, Chagrin Falls and many other communities do not. What all health
officials do agree on is that avoiding getting bitten is the best way to
keep West Nile at bay.

A Brighter Future for City’s Forest Preserves?

Elected officials say politics and mismanagement have led to the decay of forest preserves around one of the Great Lakes region’s largest cities.

Elected officials say politics and mismanagement have led to the decay of
forest preserves around one of the Great Lakes region’s largest cities. They
say a shift in control of the forest preserves and 100-million dollars will
correct the problems. The Great Lakes Radio Consortium’s Jenny Lawton reports:


Cook County’s Forest Preserve District manages 68-thousand acres of
forest preserves in and around Chicago. Commissioner Forrest Claypool
says something needs to be done soon because years of mismanagement
have left the land and its facilities in horrible condition.


“How can you possibly serve in the summertime these thousands of
families who come into the forest preserves and not provide decent
restrooms – not to mention bridges that are about to fall apart, not
to mention picnic shelters that are burned and falling down, and so
covered with gang graffiti that they’re intimidating and create an
impression of this unsafe place to be.”


Claypool says the Cook County Forest Preserve has been a dumping
ground for political patronage… including a recent financial scandal
which cost the agency almost 20-million dollars.


Three county commissioners say they have a 100-million dollar plan to
fix the dilapidated facilities and clean up the forest preserves… all
without raising taxes. The plan calls for borrowing the money by issuing
bonds. But that means they’ll need the Illinois governor’s approval.


County officials say they would save money by gutting that “bloated”
administration of the Forest Preserve District and turning over many
of its responsibilities to the county.


But nature advocates are wary that the shift in control might compromise the forest
preserve’s mission of holding and acquiring natural land.

Canned Tuna Under Scrutiny

An activist group says the Food and Drug Administration should do more to protect
children from mercury found in canned tuna. The Great Lakes Radio Consortium’s
Lester Graham reports:


The Mercury Policy Project says levels of mercury in canned tuna could be
dangerous to small children or a developing fetus. It’s calling for stricter guidelines
on eating tuna and for more restrictions on mercury pollution from coal-fired
power plants.


But the tuna canning industry says the mercury levels in tuna are lower than
the environmentalists say they are… and pollution is not the chief cause. Melanie
Miller is with the U.S. Tuna Foundation. She say the chief source is
naturally-occurring mercury from underwater volcanoes…


“There’s nothing we can do about it. It’s naturally occurring in the ocean.
So, we can’t really reduce the amount of mercury. The only thing we can do
is monitor very closely and make sure that the levels of mercury that are in our cans of
tuna are as low as possible.”


Miller says tuna fishers try to take smaller, younger tuna which have lower
levels of mercury. Miller adds that consumers should follow the FDA’s
guidelines limiting the amount of tuna eaten each week.

Some members of Congress feel the timing is right for the long-anticipated
federal legislation to help restore the Great Lakes. A bill introduced in the
Senate recently proposes EPA monitoring of the Great Lakes water quality.
Now, a bill being introduced in the House proposes a four billion dollar
Great Lakes Restoration Fund. And it has strong political support.
The Great Lakes Radio Consortium’s Joyce Kryszak reports:


A critical report by the General Accounting Office prompted
Congress to start a coordinated recovery plan. The bipartisan
bill on the Senate side would pay for more reliable monitoring of
water quality. And the House bill now being introduced – also bipartisan –
would supply four billion dollars to help restore the environmental health of the lakes.


The Great Lakes Trust Fund is modeled after a multi-billion dollar
federal plan to rehabilitate Florida’s Everglades. Congressman Thomas Reynolds of New York
is one of the bill’s co-sponsors.


“We’ve seen, from increased levels of toxins and bacteria that are
killing wildlife and closing beaches, to invasive species that are
attacking an ecosystem. The Great Lakes need more than help – they need funding.”


Reynolds says he believes the backing is there to pass the legislation –
and that federal help is long overdue.

One of the largest egg farms in the nation is being ordered to shut down. The reason… a
decade of complaints, including nine contempt citations for environmental violations.
The Great Lakes Radio Consortium’s Bill Cohen reports:


The Buckeye Egg Farm churns out more than two and a half billion eggs a year… but
Ohio agricultural officials have ordered the factory farm to close. Neighbors of the farm
continue to complain about swarms of flies and bad smells… and environmentalists
continue to complain about manure being dumped into streams. In the words of Ohio’s
agriculture director….it’s “intolerable.”


Environmental activists such as Jack Shaner are glad about the shutdown order.


“We’re happy the state of Ohio has wised up to the fact that just like violent crime, when
it comes to environmental crime, some repeat violators just can’t be rehabilitated.”


Buckeye Egg warns of job losses injuring the economy…..and it promises an appeal of
the shutdown order. Company officials say a better approach is to sell the farm to new
owners.

Small Forest Patches Breed Disease

Chopping down trees for subdivisions and farm fields isn’t just bad for forests. It can also hurt people. According to new research, small patches of woodlands breed more ticks with Lyme disease. The Great Lakes Radio Consortium’s David Sommerstein reports:

Chopping down trees for subdivisions and farm fields isn’t just bad for
forests. It can also hurt people. According to new research, small
patches of woodlands breed more ticks with Lyme disease. The
Great Lakes Radio Consortium’s David Sommerstein reports:


Felicia Keesing, a biology professor at Bard College, wanted to know
where people ran the greatest risk of getting Lyme disease, an illness
spread by ticks. She knew Lyme disease-bearing ticks are carried mostly
by the white footed mouse. And she knew that kind of mouse thrives in
small chunks of forest.


That’s because its predators need larger woods to live and have
moved away. So Keesing compared forest chunks of different sizes for
tick populations. She found a lot more ticks with Lyme disease in small
forests boxed in by houses or farmland.


“On average about seven times as likely to encounter an infected tick in a patch of woods
smaller than five acres.”


Keesing says the results send a clear message to town and village zoning boards
weighing development issues. They should do everything they can to prevent the
fragmentation of forests.


Keesing says her research doesn’t suggest small lots should be cut down altogether. But
new development could be better planned to reduce the risk of Lyme disease.
