Researchers are trying to determine whether fibers found in taconite mined near Lake Superior
might cause cancer. Taconite is a type of iron ore. The microscopic fibers found in some
taconite rock are a lot like asbestos, and asbestos causes cancer and other serious lung diseases.
Research is now underway that could determine whether the fibers in taconite can cause cancer
too. The question is a classic example of the uneasy balance between protecting health and
creating jobs. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:


The fibers in taconite first made big news thirty years ago. Reserve Mining Company was
dumping its waste rock in Lake Superior, and the fibers turned up in Duluth’s drinking water.


People worried, and started drinking bottled water, until a special filtration plant was built.
Reserve was forced to dump its waste rock on land.


But the jury is still out on whether the fibers are dangerous.


Phil Cook is one of the people who discovered the fibers in the water supply. He’s a chemist at
the National Water Quality Lab in Duluth. He studied the fibers for years.


They’re so small, you can’t see them even with a regular microscope. Cook and his team had to
use an electron microscope to get a handle on the fibers.


“Hundreds of hours of looking at many fields of view and counting particles of all sizes and
shapes and identifying them specifically as to what their mineral nature was.”


Some of the taconite fibers turned out to be more cancer-causing than others. The most
commonly occurring fibers were less dangerous.


But Cook found that some of the fibers caused even more cancer than asbestos. After two years
of experiments on lab rats, Cook found the most dangerous taconite fibers had splintered off,
multiplying the number of fibers in the rats lungs.


“So there was some kind of slow leaching going on while the fibers were in tissue, and blocky
particles would become thinner fibers. So the number of fibers were increasing and the dose was
increasing.”


But the question is, does the same thing happen to people, and are people exposed to enough of
the fibers to worry about cancer?


NorthShore Mining Company currently operates the former Reserve mine and processing plant.
NorthShore monitors its fiber emissions. Millions of fibers pour from the smokestacks. But at
monitoring stations about a mile away, the numbers drop to a background level comparable to
cities out of the area.


But some people worry even that level could make people sick.


There are no national or state standards for fibers in the air.


There are some rules for workplaces. Miners and taconite workers are exposed to a lot more
fibers than people who live nearby.


Northeastern Minnesota has a much higher rate of mesothelioma than the rest of the state.
Mesothelioma is a rare form of lung cancer caused by asbestos. Some miners are concerned
taconite could cause mesothelioma too.


The state Health Department recently completed a study of taconite workers who died of
mesothelioma. The study found most of them were exposed to commercial asbestos used as
insulation as well as taconite dust. The study concluded the commercial asbestos was the most
likely cause of the miners’ disease.


But the study looked only for mesothelioma. Some miners say it should have looked for other
diseases too. David Trach is president of a Steelworker retiree group. He says 450 former mine
workers got x-rays, and 30% of them had some kind of lung abnormality. Only a very few of
them had mesothelioma.


“We’ve got to search out for those young miners that are working now so they don’t end up like
some of my friends did at LTV Steel that are in their 60s and 70s, and can hardly breathe.”


The Minnesota Health Department has file cabinets full of information about the health of miners
and taconite workers. But there’s no money to study the data looking for other lung diseases.
That’s because last year the Minnesota state legislature eliminated the money for the project.


There’s a lot riding on whether taconite fibers are safe. Officials in the area where NorthShore’s
plant is located, would like to use the plant’s waste rock to build roads, which would spread the
taconite fibers throughout the county. Until now the company has been prohibited from selling
its waste rock by the court ruling in the Reserve case.


Also, several companies have been prospecting in the region. New mines for copper, nickel, and
other minerals could provide much-needed jobs in a region hit by mine closures and cutbacks in
the taconite industry. But they could also be digging into the same rock where the taconite fibers
are found.


After the scientific studies are published, the Minnesota Health Department will conduct a
formal assessment of the risks – if any – of taconite fibers.

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.

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.


(montage of golfers)


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.

Underwater Power Lines Still in the Works?

An Ontario power company would like to see a high-powered transmission
line built to Chicago. The plan would include stringing a high-voltage
power line under Lake Superior. The Great Lakes Radio Consortium’s Mike
Simonson has more:


This plan is part of a project that would build high-capacity generating
plants in Ontario, selling excess power to the United States. Larry
Hebert is the general manager of Thunder Bay Hydro. He says this is at
least five years off. By that time, Hebert expects the demand for power
in the U.S. to increase.


“Certainly, the need for power doesn’t seem to be diminishing, despite the cries for conservation
and wise use of power. Certainly in this province of Ontario, we seem to be
using more and more every year.”


Hebert expects the most controversial part of the project will be laying
a 90-mile long cable under Lake Superior to Michigan’s Upper Peninsula,
and run a high-voltage line down Wisconsin’s eastern side to Chicago.


Mary Pat Blankenheim with the Wisconsin-based American Transmission
Company says Thunder Bay Hydro’s proposal is intriguing.


“And especially given the fact that we are
looking for new ways of getting energy to the
areas where it’s needed.
But again the only way to get it there is by transmission.”


Hebert says they’re investigating permit applications with the Army Corp
of Engineers.

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:


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.

EXTRACTING MERCURY FROM THE DENTIST’S OFFICE

  • Lorraine Kellerman operates the mercury separator in one dental office. Kellerman says it's easy and satisfying to recycle the mercury.

Health officials warn pregnant women and children to avoid eating certain kinds of fish. Mercury built up in the fish can damage the nervous system and impair children’s mental development. The National Academy of Sciences says at least 60,000 American children are born at risk for impaired development every year because their mothers were exposed to mercury. Mercury has been eliminated from paint, batteries, and other products. Now, some dentists are doing their part to reduce the mercury going into the environment.

Health officials warn pregnant women and children to avoid eating certain kinds of fish.
Mercury built up in the fish can damage the nervous system and impair children’s mental
development. The National Academy of Sciences says at least 60,000 American children
are born at risk for impaired development every year because their mothers were exposed
to mercury. Mercury has been eliminated from paint, batteries, and other products. Now,
some dentists are doing their part to reduce the mercury going into the environment. The
Great Lakes Radio Consortium’s Stephanie Hemphill reports:


Mercury is an essential part of dental amalgam, the silver stuff used to fill cavities. The
mercury keeps the amalgam soft until it’s pressed into the cavity, then it bonds to form a
very stable, durable filling. The problem is the small bits of amalgam that are left over
after the cavity is filled. The suction hose that cleans them out of your mouth generally
dumps them down the drain. So they can easily end up in a lake or river, where they can
be eaten by fish.


The average dental office creates about a half pound of waste mercury every year. Just a
tiny portion of that would be enough to warrant fish advisories.


“The amount that’s sewered from dental offices is probably the largest input to the sewer
system.”


Tim Tuominen is a pollution prevention specialist with the Western Lake Superior
Sanitary District in Duluth. He’s been working with dentists in the city for nearly ten
years to reduce the mercury they wash down the drain.


He started with the vacuum systems nearly all dentists already have. When the suction
hose whisks amalgam out of your mouth, the pieces are held in a container to keep them
from damaging the vacuum pump. Tuominen showed the dentists how to empty the
container and bring the contents to the district’s recycling program.


In the first two years, the amount of mercury coming into Duluth’s wastewater treatment
plant was cut in half, and it’s been reduced even further since then.


To cut down on mercury even more, Tuominen got a grant to buy more expensive
equipment that captures up to 99% of the amalgam. He offered the equipment free to any
dentist who would agree to use it.


“I’ll go in and install them, train the assistants and the dentists how they operate, that only
takes about half an hour, then after six months I show them how to manage the solids
particles that collect in them over that time period. So it’s really pretty simple.”


Most of the dental offices in Duluth have installed the systems, and Tuominen expects the
rest to follow suit.


Lorraine Kellerman operates the system in one dental office. Once a week she empties
the chair-side traps and puts the chunks of amalgam into a container for recycling. Then
she goes down to the basement where a tank, like an aquarium, collects the finer particles.
The heavy amalgam settles to the bottom of the tank.


“We just put the hose in the drain, turn the lever, and you just wait ’til the fluid runs out
and then you can come back down, it doesn’t take long, it only takes a few minutes
basically.”


Once a year the amalgam that collects at the bottom is cleaned out and recycled.


Kellerman’s boss is dentist Jim Westman.


“The beauty of this technology is in its simplicity. Gravity works, it’s simple, it’s very
inexpensive.”


Westman says the dentists in Duluth are happy to use the equipment. It costs about
$500, and the recycling charge is about $50 a year.


Westman is chair of the Minnesota Dental Association’s environmental committee. It’s
been working on a plan to help dentists around the state of Minnesota reduce their output
of mercury. Westman says they want to make it easy for dentists.


“No matter where someone has question in regards to what’s going to work in my
equipment, there’s so many variations from one office to the next, who are my resources
to call or handling, transport, process materials, it’s that who you going to call side of the
question that’s going to make a difference as we build a bigger program. ”


If the voluntary program catches on in Minnesota, it could spread to other states. Michael
Bender is director of the Mercury Policy Project, a national organization working to
reduce mercury in the environment. He says dentists around the country are beginning to
feel they should do their part.


“It’s part of the cost of doing business. It’s not going to break any dentist’s back
financially to cover the cost of doing whatever it takes to be a good business, responsible
to the community, responsible to the environment.”


In December, the Environmental Protection Agency is convening a meeting on dental
mercury. The agency will publish information on ways state and local governments can
keep dental mercury out of the environment.

Bear Activity in National Park Increases

The Apostle Islands National Lakeshore plans to step up its education campaign about
the do’s and don’ts of living in bear country. Park officials hope that will end this past summer’s encounters between campers and bears. The Great Lakes Radio Consortium’s Mike
Simonson reports.


With about 30 bears on Stockton Island, some of them decided to swim for a less-
crowded scrounging area. So, this summer, campers reported bears rummaging through
their food on neighboring islands – forcing the Park Service to close a couple of
campsites.


Apostle Islands Resource Specialist Julie Van Stappen says the bear population may be a
little crowded. And even though there has been an annual hunt of bears since the mid-1990’s, she doesn’t expect much help thinning out the bear population from hunters.


“Very few people do it. You have to get out to the islands and there’s no motorized equipment allowed, so it would be a very different hunt.”


Next summer, Van Stappen says instead of moving bears or closing campsites, the best
bet is to educate campers about storing food, and not attracting bears in the first place.
She says that would be the simplest way to end the close encounters of the bear kind on
the Apostle Islands.

Fishing boats that once braved Lake Superior storms now sit idle and
deteriorating on the shore of a small village. Some of the local folks
believe the remnants of the village’s fishing past should be preserved.
Others wonder if some relics of our past shouldn’t simply be allowed to
slowly fade away? The Great Lakes Radio Consortium’s Mike Simonson
has more:


(soft sounds of waves)


This quiet, sandy beach in Wisconsin’s northernmost village of Cornucopia is
left with a few hints of its past. Three gray wooden fishing boats sit in
disrepair on the sand dunes…boats that were part of this harbor’s fleet of
25 vessels when the Lake Superior fishing industry was at its peak. These
days, the cool mornings are disturbed only by a town meeting of seagulls…


(seagulls)


They’re waiting for the lone fishing boat to return for a late
breakfast.


(fishing boat engine)


The 44-foot steel hulled Courtney Sue is the last of the fishing boats in
Cornucopia. Brothers Mark and Cliff Halverson continue a family
tradition…bringing in the day’s catch.


“How was the catch?”


“Good enough for what we needed today.”


(sound of boxes sliding onto dock)


“These are lawyers, this is a trout, and the rest are whitefish. Been kind of slow
this year. Gonna pick up, but the water’s real cold yet. The fish are still out deep.”


(sound of sharpening knives)


With sharpened knives, the Halversons gut the fish so fast that the catch
continue to flop about even after filleting.


(sound of slitting fish)


“Been doing it for quite a few years. (slop, slop) Takes awhile
to get used to handling ’em (slop).”


These men are the last of their kind in town. The rest of the fishermen who
sailed on boats like the three beached relics have either left Cornucopia,
retired or died.


Fishing peaked in 1955. Then, it became a casualty of over-fishing and the
invasion of the sea lamprey…a life-sucking eel with no natural enemy in the Great
Lakes. It devastated the fishing.


(fishermen playing cribbage)


Most days you can find 64-year-old “Snooks” Johnson and 74-year-old Harold
Ehlers among a friendly game of cribbage at Corny’s Village Inn.


“Sorry, Harold.”


“Well, you’re gonna get better, I know.”


“Well, I can’t get any worse (laughs).”


Ehler’s family has owned the town general store since 1915. He remembers
the men and women who made fishing their livelihood from the 1920’s till
the 50’s.


“I have to say they were very independent people. They just depended on their skill to make a living.”


Harold Ehler’s store played a critical role…making sure fish got to the
market fresh, and for good prices.


“So their market was mainly in Chicago… my dad spent most of his noon hour
on the phone, which wasn’t that great in those days. Selling the fish. Then we’d go down and tag ’em, put them on a truck and take them to the railroad station in Ashland and so they’d get there the next morning.”


(sound of waves)


The old wooden boats now weathering on the beach are just about all that’s
left of that heritage. Battered letters spell out “The Eagle,” “Ruby,” and
“Twin Sisters.” Some people in Cornucopia hope to save the old boats from
the ravages of Lake Superior. “Snooks” Johnson’s family operated “Twin
Sisters”…and he joined the crew as a teenager in 1955…the last good year.


“Yeah it looks kinda sad, doesn’t it? How it got its name, my Dad’s brother had
twin daughters so that’s what the “Twin Sisters” came from. It was a pretty good boat.”


Johnson says these homemade wooden boats were plenty seaworthy…with lots
of room for fish and a crew of four or five.
“But they all rolled and I’d always get seasick when I was on the thing. Because
when it was rough weather and you took the fish in and piled them up on the
bow so they wouldn’t roll too much, because the bow would keep them confined.
And you had a stove that burned coal just for heat. Someone would start cookin’.
So you would have the engine smells, the coal smells and the half-cooked fish
smells. I spent quite a bit of my time sticking my head out that gangway right
there to chum the fish.”


Johnson says remembers Tom Jones, the builder of these boats. The oldest
dates back to 1927. The others were built in 1935 and 1940.


“What he would do is make half a boat, a model. He’d say well
this is the way you guys want it or whoever one like this, or one like
that. They’d agree on it and that’s how it would turn out. I think he had
about a third or fourth grade education, but he was brilliant. Nobody really
knows how to work on them anymore.”


When Tom Jones passed away, so did the know-how of restoring these boats.
Now, protected only by a rope to keep people from climbing onboard, these
remnants of a more prosperous day slowly decay.


A “Save the Boats” committee was formed, but recently dissolved. This
village of 50 people just doesn’t have enough resources, says the former
co-chair of “Save the Boats,” Phyllis Johnson. She hopes somebody someday
does something for the boats…


“It’ll be as a result of someone saying, “Hey, those boats are lookin’ pretty shabby, aren’t you gonna get the young people around, have them work on them or something.”


But nothing has happened yet. Not even so much as a coat of paint protects
the boats. The sterns and hulls are cracked open. Only one boat has a
propeller. Johnson would like to do something, but she’s realistic.


“In the end they’re going to go back to nature. They’re not going to float again, never. But as a part of heritage, it’s probably better to keep them in as good as shape as we can keep them as long as we can.”


Snooks Johnson says as each season takes its toll on the old boats, it’s
likely preservation isn’t in the cards.


“I don’t know, I kind of like to see it just the way it is.
fishing went to hell, and so do the boats. So they’re kind of following
suit and they’ll still last a long time I guess. I don’t know, a lot of
memories.”


But there are fewer and fewer people to share those memories remaining in
Cornucopia. And fewer people to worry about the fate of the old fishing
boats.

Cash to Clean-Up Polluted Lake Sediments?

The U.S. House of Representatives has passed a bill that would
provide two hundred and fifty million dollars to help clean up the bottom
of the Great Lakes. A similar bill is currently working its way through
the U.S. Senate. The Great Lakes Radio Consortium’s Matt Shafer Powell has
this report:


It takes a long time for water to find its way out of most of the Great
Lakes. For instance, Lake Superior can retain its water for more than 150
years. But that means that it also takes a long time for those lakes to get
rid of pollution. Representative Vern Ehlers of Michigan says that’s why the
government needs to step in and help…


“You know once a lake is contaminated, it’s contaminated for a very long
time. And if you’ve got non-biodegradable contaminants, you’ve got a major
problem.”


Ehlers was one of the sponsors of the Great Lakes Legacy Act, which just
passed the House. If passed into law, the Act could provide money to the
EPA to assist in the clean up of polluted sediments on the lake floors.
Some scientists have linked those sediments to a variety of health problems,
including birth defects.

A spiny fish that can hunt in the dark has invaded Lake Michigan. The foreign fish is known as the Eurasian ruffe. And as the Great Lakes Radio Consortium’s Annie MacDowell reports, biologists fear the ruffe could harm the lake’s yellow perch population:


Experts say the ruffe is originally from the Black and Caspian seas, and it’s an
efficient little machine. It lays enormous numbers of eggs and has no predators because of its spiny skin. Gary Lamberti is a professor in the department of biological sciences at the University of Notre Dame.


He says the ruffe are depleting the yellow perch’s food supply.


“The Eurasian ruffe are specialists on that food, that is they eat that food all the
time. And those are the worms and aquatic insects that are found at the bottom of
the lake. That’s what ruffe eat and that’s also what perch eat at a certain stage of
their lives. But ruffe do it all the time and they do it better.”


Lamberti says the yellow perch’s population is already declining in the Great Lakes,
probably due to competition from many invasive species.


The ruffe could be another blow to the commercial fishing industry, as yellow perch
are widely harvested for food and are a favorite among sportsmen.


The Eurasian ruffe probably migrated from Lake Superior, where they were first
discovered in the 80’s.

Japanese Homes to Solve Housing Crisis?

The cost of building a home is soaring. Materials are expensive, and skilled labor is scarce. The high costs are contributing to a crisis in affordable housing, in the Great Lakes region and around the country. A new technology from Japan could be part of the solution. The structural pieces of a custom-designed home are cut out in a factory, using wood manufactured from small-diameter trees. Even unskilled workers can assemble the house on site in about a day. The Great Lakes Radio Consortium’s Stephanie Hemphill watched a home as it was being built:

The cost of building a home is soaring. Materials are expensive, and skilled labor is scarce. The high costs are contributing to a crisis in affordable housing, in the Great Lakes region and around the country. A new technology from Japan could be part of the solution. The structural pieces of a custom-designed home are cut out in a factory, using wood manufactured from small-diameter trees. Even unskilled workers can assemble the house on site in about a day. The Great Lakes Radio Consortium’s Stephanie Hemphill watched a home going up:


Five East 5th Street is a narrow lot a few blocks above downtown in Duluth, Minnesota. A new basement juts out of a hole in the hillside. From the front yard, there’s a spectacular view of Lake Superior.


Most of the houses in this neighborhood are at least 80 years old. They’re small houses built for working families. A few vacant lots show where dilapidated houses were torn down.


One day last month, the new house arrived on a truck.


(sound of Martin listing parts)


Santos Martin works for Kato Sangyo, the Japanese company that invented this system of homebuilding. He calls out the part numbers as half a dozen apprentice carpenters carry the pieces off the truck. Soon the lot is covered with stacks of house parts – corner posts sixteen feet long, and insulated wall panels in various sizes, as big as 4 feet by 9 feet.


Then the workers start to put the pieces together.


“Every component is numbered, every component has a specific place and an internal metal connector that allows you to put it together like you would a TV entertainment center or a bed frame.”


James Brew is the architect who had the dream for this house.


Brew was fascinated by Japanese culture since he was a kid. He’s traveled to Japan several times, and hosted exchange students in his home. Two years ago he learned about a Japanese company that created a home-building system that allows even inexperienced workers to frame up a custom-designed house in a day,


“People who haven’t built with this system, there they are pounding together a beam and a post and with a little bit of weather cooperation they will probably have this entire house framed today.”


The beams are made of laminated strand lumber. Instead of cutting big trees into 2 by 4s, laminated strand lumber uses smaller trees and even waste wood, glued together like plywood.


This type of “engineered wood” is being used more and more in homebuilding. What sets the Kato Sangyo system apart is the way the framing pieces are locked together with metal connectors.


The beams for this house are four inches square, and either eight or sixteen feet long. At the end of each beam there’s a slot for a metal connector. It’s like a large hinge. Workers slide one end of the hinge into the beam, and match the other end to a slot in the floor.


Then they raise the beam until it’s standing upright. They slide the insulated wall panels into the spaces between the beams. Everything is supposed to fit precisely because it was cut to order in a factory. Once the framing is up, workers will add siding, and the house will look just like the other ones on the block.


The assembly is mostly a matter of matching the right parts. So it’s an ideal project for people who are just learning how to build. Lisa Lyons is one of the crew members. She and her co-workers are part of a job training program for battered women. After a year of learning standard construction techniques, Lyons says this job is fun.


“Before it’s a lot of framing, a lot of measuring, and this here you just pound in some pegs and stand it up and it’s just like lego blocks, it’s really cool.”


The Japanese system offers not only speedy construction, but the potential for more affordable housing. The parts for this house were made at a factory in Minnesota. They were cut by hand, which took a couple of days. Architect James Brew says they could be cut in a couple of hours in a fully automated factory.


As the house takes shape, visitors stop by to watch. They include businesses thinking about the Japanese system as a possible new industry for Minnesota. James Brew says it would cost about a million dollars to buy the equipment to make the house parts. And he’s talked with a lot of lumber and construction firms that are intrigued with the idea.


“So there’s many interests in the system and the idea, the technology, but it’s again chicken and egg. Which is first, sales without a factory, or factory with no sales, or together. It’s very difficult.”


Brew is hoping the house in Duluth will provide the demo that will spur some business to decide there’s a future for the Japanese system in the United States. For the Great Lakes Radio Consortium, I’m Stephanie Hemphill in Duluth.
