Environmental work isn’t just for young professionals anymore.
Retired engineers, former biology teachers, and others with time on their hands are working on

environmental problems as volunteers. The Great Lakes Radio Consortium’s Jennifer Szweda Jordan

reports on how senior citizens are keeping environmentally active:


(Sound of bird)


75-year-old Ivan Pettit is officially retired from his job as an environmental regulator, but he

hasn’t stopped monitoring streams, promoting recycling, and solving a nagging safety issue in his

state.


(Sound of walking)


On a sunny day in Oil Creek State Park in northeast Pennsylvania, he drops a stone down a corroded

pipe.


“Okay, go.”


(Sound of rattling, splash)


Pettit is estimating the depth of this remnant of an old oil well. It’s one of thousands of

abandoned oil wells in this region. The wells date as far back as 1859. Pettit and a team of senior

volunteers regularly hunt for old wells. The seniors’ work improves water quality and safety for

hikers and hunters, and Pettit says it helps keeps him fit.


“It is work that I have always enjoyed doing as well as getting you outdoors and being able to

observe the things that’s going on around you, that is not a sedentary task whatsoever.”


Pettit belongs to the national Environmental Alliance for Senior Involvement. The group claims

members as young as fifty-five. Pennsylvania has the third highest number of residents older than

sixty among U.S. states. Its active Senior Environmental Corps is touted as a national model, and

has been honored by the United Nations Environmental Program.


But senior groups across the nation are working on environmental problems. In Cape Cod, they

monitor West Nile virus. Seniors clean hazardous waste sites in Indiana. Michigan volunteers

install solar water heaters on poor peoples’ homes.


It’s a fast growing program. In 1993, 26 older adults made up the Senior Environment Corps. A

decade later, over 100 thousand were involved in work across the country.


Ivan Pettit’s work looking for old oil wells is the kind of effort that makes a real difference.

Besides being a hazard for hikers and hunters, some of the old wells seep oil into the ground and

it gets into streams.


In less than two years, the seniors have found almost two hundred wells. Environmental Alliance for

Senior Involvement president Tom Benjamin compares that to two college interns who worked full-time

one summer, and found fewer than fifty.


“Most of these individuals that were volunteers know that community and know the area. They grew up

there, they hunted those woods, they know what a oil well looks like, so they have some instant

recognition.”


(Sound of forest)


Every other week, from spring to fall, the well hunters line up horizontally, twenty feet apart,

and comb a section of forest. Some well holes are several feet across and twenty feet deep. Others

have narrow openings, but drop as deep as a thousand feet. Evelyn Kolojejchick and her husband John

lead Ivan Pettit and other volunteers in seeking out the wells and marking coordinates.


“Ok, longitude is?”


“Seventy-Nine.”


For both Evelyn and John Kolojejchick, well-hunting and other environmental projects are an

extension of teaching high school science for thirty years. Evelyn once aimed to spark interest in

many young minds. Now she feels she’s working on a smaller scale, but hopes to remain effective.


“I belong to Audubon, used to belong to a lot of other environmental organizations and it just

seemed like you needed… you needed to do something that was going to make a difference. I never

had any money to donate to all of these causes and you just you know, you want to do something that

an individual can do.”


Recently, the seniors saw results of well-hunting. They found sensitive species in a stream that

had once been polluted. Several oil wells nearby had been sealed with cement to keep acid mine

drainage out of the water.


“The first year we tested it for aquatic life, there was almost nothing there. And yesterday when

we were there, we had better diversity in that stream than we have in some of our streams that we

test all along that we know don’t have those kinds of problems. So they have made a significant

difference on that stream by plugging those wells. It’s remarkable.”


And it’s the kind of reward that these senior citizen volunteers had hoped for: making a difference

in their part of the world.

Every year, tens of thousands of avid birdwatchers wander through
frozen fields and marshy swamps. Their job is to record as many birds
as they can find in a given area. For birders, it’s a day to enjoy the outdoors
while doing what they love most. But as the Great Lakes Radio Consortium’s
Karen Kelly reports, that passion serves another purpose – it helps scientists:


(sound of footsteps)


Georgina Doe: “There’s five robins right there and there’s three common mergansers,
males…”


Georgina Doe scans the shoreline with her binoculars. Within seconds,
she spots a tiny glimpse of a bird and names it.


She knows them by the way they dive in the air, and the way they thrust
their chests out.


Doe has been scanning the treetops of Carleton Place, Ontario for
more than 30 years. She says she loves the chase and the element of surprise.
And over the years, birding has also been her escape.


She remembers watching a robin build its nest when her grandson
was seriously ill.


“So I used to count the birds every morning before I went off to
the hospital. And then after that, you come back to reality. Somehow a
little bird can just make you feel better.”


Birds have been a part of all of our lives. We might not know their names.
But we can remember holding a baby chick. Or hearing a cardinal on a crisp cold day. But now, many bird species are dwindling. And scientists are
counting on birders like Georgina Doe to help them find out why.


Doe is one of many birders in North America who collects
information for scientists. Jeff Wells works with that information
at Cornell University’s Lab of Ornithology.


“There’s no way that we could ever pay the tens of thousands of
trained biologists that would be necessary to gather this kind of
information. It’s only possible when we can engage volunteers like
we do in citizen science projects.”


Cornell runs at least a dozen programs that rely on information
from average birders.


There’s the Christmas Bird Count. About 50 thousand people participate.
Another 50 thousand track species during the Great Backyard Bird
Count in February.


The volunteers reported that wood thrushes are disappearing in
many areas. And they’re tracking the effect of the West Nile Virus
on bird populations.


“If a little bird dies, usually it just disappears quickly
and no one ever sees it. So we don’t really know the impact.
And so looking at the differences in the numbers and distribution
might give us some sense of when the disease was rampant in the summer,
whether it killed off enough birds to make a noticeable
difference in our count.”


(sound of quiet footsteps)


Robert Cermak: “You can see it’s about 10 inches high. It’s all fluffed
up right now…”


Birder Robert Cermak tiptoes closer to a barred owl sitting in the
crook of a tree. We’re in Ottawa, Canada’s capital and a city of about a million
people. When it comes to bird counts, this is Cermak’s territory.


“It’s not often that you see a barred owl, any owl, during
the day. They’re usually more secretive. This one is not too
afraid to be out so it’s probably more accustomed to having people
around it, since this is the center of the city.”


Like Georgina Doe, Cermak has been birding for years. But even with
veterans, there’s always concern about their accuracy. Cermak
discovered this firsthand when he reported seeing a rare
harlequin duck last year.


“I sent it in and a few hours later, someone from Cornell –
very politely because it’s a delicate subject to question
someone’s sighting of a rare bird – but they very delicately
indicated that a harlequin duck is extremely unusual in Ontario and
could I please provide a few extra details.”


Cermak sent them a published account of the sighting. He also
gave them the number of a local expert.


Jeff Wells says researchers check their facts carefully. They look
for reports that don’t match others in the surrounding area. Sometimes
an investigation turns up a trained ornithologist… and sometimes not.
But overall, Wells says the information has formed the basis for
hundreds of published studies.


That’s something that makes birders like Robert Cermak and
Georgina Doe feel proud.


“It’s nice because you’re contributing. You’re doing a
lot of hours, it uses a lot of gas, you go around a lot of blocks
but we just think it’s important.”


(sound of Georgina Doe walking)


Georgina Doe says she doesn’t really think of herself as a
scientist. But she’s out there every day, with her ear to the wind. And that’s
what the scientists are counting on.

Rats Scurrying to the Suburbs

  • Life in the suburbs is idyllic to some people... (Photo by Bon Searle)

Unusually heavy rains this summer are partly to blame
for rats pouring out of the sewers in droves all over the country, and the nasty vermin are relocating to some of the most pristine
neighborhoods. The Great Lakes Radio Consortium’s Joyce
Kryszak explains what caused the rat invasion and
what’s being done to evict them:

Transcript

Unusually heavy rains this summer are partly to blame for rats pouring out of the sewers
in droves all over the country. And the nasty vermin are relocating to some of the most
pristine neighborhoods. The Great Lakes Radio Consortium’s Joyce Kryszak explains what
caused the rat invasion and what’s being done to evict them:


Piercing blue autumn skies and billowing white clouds drift across the chimneys of this modest,
but perfectly manicured suburb. There aren’t even many leaves crunching under foot. Town workers
have already come and vacuumed them all away. But there’s a nasty little secret scurrying under
the porches and behind the garden sheds in this Western New York town. County Sanitation Chief
Peter Tripi takes us for a peek.


“Can you see the teeth marks here? That’s actually rat gnaw marks. And there’s the garbage bag.
And that’s what we found when we went to this property.”


Now, you might be thinking that we trudged through derelict grass and scattered debris to find
these rat clues. Nope. This is a gorgeous, manicured yard – with not a blade of grass out of
place. But Tripi says rats aren’t choosy.


“You would never think by looking side to side that there would be a rat problem in this yard.
Doesn’t matter what neighborhood you live in, or how much money you’ve got. There’s no difference.
They just like your food.”


And you’d be surprised where rats can find food. A garbage can left even briefly uncovered, a
neglected bird feeder, uhhh… dog feces… and even a compost pile.


“Absolutely. This is a rat condo. It’s a grass-clipping compost pile that basically housed rats
to go a hundred yard radius all the way around to the different houses.”


Tripi says rats had to get creative with their housing. A summer of extremely heavy rains drove
the out of the sewers and into some previously rat-free neighborhoods. And with the West Nile
virus killing off millions of birds, the rats have less competition for the food they’re finding
above ground. The consequence is a virtual rat infestation all the way from New York and Illinois
to Virginia, Michigan and L.A. In Kenmore, there have been four thousand rat complaints – nearly
double last year.


(Sound of garbage truck)


Of course, none of this is news to the garbage collectors. They see the problem up close and
personal. Twenty-year veteran Louie Tadaro says this past summer is the worst he’s ever seen.


“Across the street there’s an alleyway and there had to be like ten of them in there, And we
started chasing them with garbage cans trying to kill them, but we couldn’t. By the time we
got there they just split.”


The problem is, they don’t split for long. Vector Control Chief Tripi says now that the rats
have relocated from the sewers to upscale accommodations, they kind of like it.


“And what that means is that they want to live with us. They want to be near our garbage and
our bird feeders. The problem with that is that rats carry diseases.”


We all know about stuff like typhus and the bubonic plague. But there are emerging diseases,
such as a pet-killer called Leptospiroris. It’s killing dogs all across the country. Tripi
says they need to get rid of the rats before the disease starts spreading to humans. So, his
team is taking the rats on, one yard at a time.


Tripi and his Vector control team set rat traps, they fill bait boxes with poison, and – when
they have to – they issue citations to residents who don’t heed the town’s new “rat control rules.” Covered garbage cans only. Clear away all brush. Clean up scattered bird seed and dog feces. Slowly, the rules seem to be working.


(sound of Tripi looking into rat trap)


Still Tripi says it’s mostly educational warfare. And he says now – heading into winter – is the
best time to nip the problem. If the rats get cozy, not only will they stay, they will multiply.
Fully nourished, one adult rat can breed up to sixty baby rats a year.


“The adult rat can live on a little bit of food, but he can’t procreate unless he has a lot of
food source. And they can’t live through the winter unless they’re warm and fattened up.”


So now is the time to – quite literally – put a lid on it. Keep those garbage cans covered, unless
you want some uninvited furry guests this winter, and many, many more come spring.

New Mosquito Borne Virus Headed This Way?

Experts in infectious diseases believe it might only be a matter of time before a new mosquito-borne virus arrives in the U.S. This one could be more devastating than West Nile. The Great Lakes Radio Consortium’s Tracy Samilton reports:

Transcript

Experts in infectious diseases believe it may only be a matter of time
before a new mosquito-borne virus arrives in the U.S. This one could
be more devastating than West Nile. The Great Lakes Radio Consortium’s
Tracy Samilton reports:


Rift Valley fever used to be confined to sub-Saharan Africa, but in
2000, there were outbreaks in Saudi Arabia and Yemen. Sonja Gerrard is
an epidemiologist at the University of Michigan. She says there’s no
reason Rift Valley fever couldn’t show up here. The disease is
transmitted by mosquitoes, just like West Nile; but unlike West Nile,
many different species of mosquitoes can carry it.


“Most people that get the disease will recover but it does in certain
instances cause encephalitis, which in cases of hemorrhagic fever can
lead to death”


Gerrard says the most devastating effect of Rift Valley fever is on
livestock. Up to 30% of a flock of sheep or cattle can be killed
during outbreaks. Because it’s considered likely the disease will
reach the U.S. sooner or later, she says research on developing a
vaccine should begin now. For the Great Lakes Radio Consortium, I’m

Used Tires Dumped in Low-Income Neighborhoods

Some low-income suburbs of major metropolitan areas are dumping grounds for used tires. But who’s dumping the tires continues to stump the authorities. In one state, authorities hauled off more than 40,000 used tires last year… and more keep showing up. The Great Lakes Radio Consortium’s Jenny Lawton has this report:

Some low-income suburbs of major metropolitan areas are dumping grounds for used tires. But
who’s dumping the tires continues to stump the authorities. In one state, authorities hauled off
more than 40-thousand used tires last year… and more keep showing up. The Great Lakes Radio
Consortium’s Jenny Lawton has this report:


Today’s job is a small one — inspectors from the Illinois Environmental Protection Agency
have been called in to remove about 3-thousand tires buried in an overgrown junkyard in a remote
corner of Blue Island, a suburb south of Chicago.


The state is paying for this clean-up, because tires are more than a nuisance, they’re a public
health problem.


This unpenned junkyard is overgrown with weeds and swarming with mosquitoes.


State EPA tire inspector George Skrobuton swats a big one from his elbow as he directs his crew.


“You’ve got all these tires here right now. They’re mixed between mattresses, garbage, clothes,
trash, leaves… See what they do is they get these tires out of the trees, the bushes, and the trash –
and they put them in a nice big pile, and they load the piles into the truck – it’s easier that way.
So, I mean, we’ll do the best we can, we’ll try to get every tire off the ground, if possible. And
hopefully, it’ll stay this way.”


The head of a back-hoe pushes aside a heap of garbage and its jaws close on a pile of almost a
dozen tires. Water streams from the knot of rubber as its lifted and dumped into an open semi
truck.


Skrobuton and his team have been called in to remove thousands of tires across the state, piles left
by rogue transporters who are paid to take them away, but pocket their fee instead of taking them
to be processed legally.

Some speculate the dumpers come from as far as Indiana to dump semi-truck-loads of the tires
under the cover of darkness.


Because these tires are on public land, Skrobuton’s team is cleaning them up for free as part of the
state EPA’s tire removal program.


But Skrobuton says this is a problem that just won’t go away.

“We can’t keep cleaning up these tire sites – it costs a lot of money. Y’know especially out here in
the south suburbs, I mean, there are so many forest preserves, and nooks and crannies like this,
that they could dump tires forever. And we don’t know where they’re coming from and that’s a
problem. Y’know, and unlesss they catch them in the act, we’re stuck with this problem.”


Over the last two years, dumpers left over 35-thousand tires in suburban Dixmoor.


With a population of less than 4-thousand, this poor suburb doesn’t have the money to remove the
tires… or fund a police force to keep the dumpers at bay.


So dumpers left their loads in alleys, vacant lots, even behind a school for years.


Village trustee Jerry Smith says the town was helpless until the state EPA came in and removed
all 18-truck-loads of tires last month.


“It’s just horrible, y’know – you go out there one day and it’s clear. And then you come back the
next day, you got 10,000 tires facing you. Well, what are you going to do with them? You can’t
pay the money to dispose them because you don’t have the money to dispose of them. There’s
nothing in our budget we got in there to dispose of tires what’s been dumped. So it’s just a burden
on us.”


But the state EPA’s Todd Marvel says the town had to move the tires because they’re a health
hazard.


He says the mounds of used tires draw more dumpers. And when tires catch fire, they produce a
toxic smoke, and Marvel says spraying water on them just makes things worse.


“So when that tire burns and you put that water on it, you’ve got a pretty contaminated run-off
there, a very oily run-off. And any surface water that’s in the area can be immediately
contaminated if that oily sheen is not contained properly.”


And, of course, there are mosquitoes. Marvel says each tire off its rim can breed thousands of
them, so these dumps are a breeding ground for West Nile.


Because of health concerns in the past, the state started a program to help get rid of these tires.


The state’s used tire clean-up program was created as a way to get the tires out of the state’s
junkyards, and into a useable industry.


People who purchase tires in Illinois pay a fee of $2.50 for each tire, new or used, which goes to
fund clean-ups and put back into the state’s used tire industry.


Most of the tires are shredded and mixed with coal to burn in power plants. Shredded tires can
also be used as the surface for everything from football fields to highways to playgrounds.


Marvel says the program has been so successful, Illinois’s demand for used tires actually exceeds
its generation rate.


“In fact, Illinois is a net importer of used tires. And the state of Illinois is constantly looking at
other markets and developing those markets to ensure that all of the used tires that we generate
and that all of the used tires that we clean-up through the dumps throughout the state have
someplace to go.”


But not all the tires end up where they’re supposed to go. Even though dumpers charge the fees
to process them properly, some of them steal the money and dump them in places such as
Dixmoor.


Dixmoor trustee Jerry Smith says once the tires show up in his town, they don’t have the money
to process them.


He says one company quoted him a price of $6 a tire. Multiply that by thousands.


So for now, he’s hoping the state EPA’s clean-up will last the town a long time.


Although the state EPA has offered Dixmoor support for added surveillance, Smith says a few
well-placed boulders and barricades seemed to do the trick.


Until last week, when 15 truck tires showed up in an alley.


Smith is cautiously optimistic this most recent find won’t multiply overnight.


“Let’s hope not. (laughs) I hope not. I really hope they don’t.”


But Dixmoor’s a small town and can’t afford a large enough police force to stop all the dumpers.


That means, chances are, abandoned tires will start showing up in back alleys and vacant lots
again soon.

West Nile Virus Marches West

  • Zoos have helped public health officials monitor the spread of the West Nile virus. Besides concerns about human health, zoos are worried about the birds in their care.

Cooler weather sweeping the Great Lakes region means the end of the mosquito season. It also means a temporary halt to the spread of West Nile virus in the area. But this past summer the virus made headway into the region much faster than experts had expected. The Great Lakes Radio Consortium’s Lester Graham reports:

Cooler weather sweeping the Great Lakes region means the end of the mosquito season. It also means a temporary halt to the spread of West Nile virus in the area. But, this past summer the virus made headway into the region much faster than experts had expected. The Great Lakes Radio Consortium’s Lester Graham reports.


It’s extremely rare that West Nile virus causes severe illness in humans. But it does happen. While most people won’t even realize they’re infected, about one fourth of those infected will exhibit some mild symptoms. However, the virus can cause encephalitis, which is an inflammation of the brain. In very rare cases it can be fatal.


Zoos have been helpful in monitoring the spread of the disease. It was first identified here in the U.S. by the Bronx zoo in the fall of 1999 after crows started dying in the New York area. Since then, zoos across the U-S have kept watch on their birds and animals. In part to protect them and in part to help health officials track the progress of the virus.


Scientists thought the virus would slowly make its way to neighboring states. But, it’s spread much more quickly than expected. It wasn’t supposed to hit states as far west as Illinois and Wisconsin until sometime next year. But it made it even farther west with reports of it in Missouri.


Researchers have learned the virus is carried by birds such as crows, blue jays, hawks and Canada geese. Dominic Travis is a veterinary epidemiologist at the Lincoln Park Zoo in Chicago. He says since West Nile virus infects birds, experts suggested it would spread southward from New York. That’s because many birds, including some infected with the virus would travel south for the winter. Others, though, said it could spread west.


“And, the westward race won. We were fairly surprised that it came past the Michigan and western Ohio area, but we’ve been prepared because we started this surveillance system and started working with the CDC and USDA and everybody last spring for this specific eventuality.”


Travis says zoos across the Midwest started monitoring for West Nile virus this past spring. They worked with local health officials to determine if the disease had spread to birds in the area.


While birds carry the disease, mosquitoes spread it. So, officials at he Lincoln Park Zoo have been trapping mosquitoes and drawing blood from its animals, testing for West Nile virus. They’ve also been working to reduce the chance that animals will be bitten by mosquitoes. Again. Dominic Travis.


“The two strategies are try and limit the mosquito and if you can’t limit the mosquito, limit the contact.”


Most zoos are hesitant to use insecticides to kill the mosquitoes. So, instead, they try to eliminate places where they can breed. Basically, that’s anywhere a puddle of water stands for more than four days. Travis says that helps meet strategy number one, limiting the mosquito.


“So, a) if you don’t have mosquitoes, the risk is fairly low, and b) if you can’t get rid of all your mosquitoes, then you want to stop mosquitoes from biting the animals and so you do things to keep them separate. And those are –depending on the birds, the size, the situation, the zoo– those are keeping them in during mosquito feeding hours or some people have mosquito nets that they’re incorporating and so on and so forth.”


Zoos are especially worried because they’re responsible for some very rare birds, in some cases the last of a species.


At the Saint Louis Zoo, a huge outdoor flight cage and several other outdoor cages make up the zoo’s bird garden. Zookeeper Frank Fischer says outside bird exhibits are at highest risk.


“We’re making sure that, trying to make sure that none of our birds, even the birds in the outside exhibits here in the bird garden don’t contract any of that disease, say, from crows or our blue jays or birds of that type.”


While birds are most at risk of infection, they’re not the only species hit by the virus. In the U.S., as many as a dozen people have died after being bitten by a mosquito carrying West Nile virus. And even more horses have died. People and horses are considered incidental victims. That is, they don’t carry the disease and they don’t spread it. But they can be infected. A veterinarian in southwestern Illinois, Don Van Walleghen, says he’s gotten a lot of calls from worried customers, asking about West Nile virus.


“Basically, they want to know, is it here? Is it a concern for me?”


And because it’s such a recent phenomenon Van Walleghen’s customers have a lot of other questions. They bring in dead birds, wondering if their dog or cat that was playing with the bird might be infected. So far, aside from horses and people, there have been no reports of other animals, livestock or pets, being infected by West Nile virus, or spreading it.


“In humans, if you are a human bitten by a mosquito that had this disease, you could not transmit it to your kids or to anything else. So, at least that limits the disease from even being thought of as any kind of epidemic.”


But it is spreading. Experts hope that weather conditions next year are not good for mosquito production. But even a relatively normal to dry season as this past year was has not seemed to slow the spread of West Nile virus. If next year is wetter, experts say the virus could spread farther and infection rates could rise. That’s why health and agriculture experts are reminding people to work toward reducing the mosquito population next year. They recommend everything from keeping roof gutters unclogged to prevent standing water, to landscaping yards and driveways to eliminate puddles. Anything that will slow mosquito production next year will hopefully slow the spread of the West Nile virus. For the Great Lakes Radio Consortium, this is Lester Graham.

Researchers might soon have a vaccine to protect birds from the West Nile virus. The Great Lakes Radio Consortium’s Lester Graham reports.


The centers for disease control and the U.S. Army are getting help to develop a vaccine for prevention of the mosquito borne West Nile virus. Here in the U.S. in the past couple of years, the virus has been responsible for the deaths of thousands of birds from more than seventy species. Michael Hutchins is with the American Zoo and Aquarium Association. He says research into a vaccine ahs been driven by the need to protect birds in zoos.


“The current studies are to develop an injectable vaccine, but the intention is to try to take that and develop an ingestible variety that could be spread on bird feed and would therefore have a hopefully-big impact on wild birds as well.”


Chicago’s Brookfield Zoo, the Walt Disney Foundation, the Wildlife Conservation Society and the American Bird Conservancy have all contributed to the project. Hutchins says a vaccine could be developed as soon as the next month or so. For the Great Lakes Radio Consortium, this is Lester Graham.
