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.

Study: Common Products Damaging Food Chain?

The anti-bacterial soap and the toothpaste you use might be damaging the base of the food chain in your local streams. The Great Lakes Radio Consortium’s Lester Graham reports:

The anti-bacterial soap and the toothpaste you use might be damaging the base of the food chain
in your local streams. The Great Lakes Radio Consortium’s Lester Graham reports:


Chemicals from personal care products, including things such as certain soaps, deodorants, hair
dyes and contraceptives appear to be reducing the number of kinds of algae in streams. Algae is
the base of the food chain for aquatic life. In a report in the journal Nature, University of Kansas
researcher Val Smith and a student exposed algae to the chemicals at levels typically found after
they’ve been through the wastewater plant. The diluted chemicals from the personal care
products killed some kinds of algae in the lab experiment.


“So, that means that these anti-microbials, even though they’re designed to do other things for us,
seem to have a negative effect on something we like which, of course, is algae in streams.”


The next step is to see if the lab findings can be confirmed in the field.

When the Well Runs Dry

In the Great Lakes region, the idea of not having enough water is ridiculous to most people. But that’s beginning to change.

In the Great Lakes/Midwest region, the idea of not having enough water is ridiculous to most
people. But that’s beginning to change. Environmentalists are sounding the alarm that water tables
are being threatened in some areas. And they’re calling on policy makers to rein in the farms and
industries that are putting the biggest drain on those resources. The Great Lakes Radio
Consortium’s Sarah Hulett has this report:


In a region that holds the world’s largest freshwater supply, worries about water scarcity are
beginning to creep into dinnertable discussions. Here in rural central Michigan, about 200
households have complained that their wells have dropped or gone dry during the summer months.


“Most kids are looking forward to summer vacation, getting out of school. My kids dread
summer.”


Susan Rodriguez is the mother of six children. She says her well first went dry about three years
ago. That was shortly after two large-scale farms began watering their crops with high-capacity
irrigation wells. Those farms together can use as much water as 11,000 households. Since then,
the summers have been dry, and difficult – because there’s no water in the house. Rodriguez says
they do what they can to get by. They don’t have the money to put in a new well. So during the
irrigation season, she and the kids go to a cemetery. It’s about a half-mile from their house, and it
has a hand pump. The family fills five-gallon buckets to bring home so they can flush the toilet…


“We buy bottled water for drinking, we buy paper plates and paper cups so I don’t have to wash
dishes. We go to neighbors for showering, for bathing. We eat out a lot because you can’t really
cook without water. It gets real expensive.”


Rodriguez and several other families began lobbying their state lawmakers for relief. And this could
be the year that they get some. Legislation introduced by Michigan lawmakers takes two
approaches. One would set up a means for people to take their grievances to state officials. The
other would require industries and farms with high-capacity wells to apply for a state permit if they
want to operate in areas where there are groundwater disputes.


Business groups are reacting with skepticism to any plan that would impose limits on water use.
Mike Johnston is with the Michigan Manufacturers Association.


“Our first position would be there’s no regulation needed at all. Having said that, we recognize the
political will is going in a different direction.”


And that different direction is being led by environmentalists. Noah Hall is the water resource
program manager for the National Wildlife Federation.


“Right now, the state of Michigan has basically no protections in place for our groundwater and
aquifers. Nothing that protects well owners, or protects the rivers and streams that depends on
underground aquifers. Other states in the Great Lakes region do have some protections in place.
And so Michigan is pretty far behind the curve right now on this.”


None of the regulations being considered in the Michigan Legislature would be as strong as what’s
already on the books in Wisconsin and Minnesota. But the Manufacturers Association’s Mike
Johnston says Michigan’s deep glacial cavities hold an ample supply of water. He says any
regulation should be very narrowly crafted.


“Michigan has vast groundwater supplies. There are a few areas of the state, very specific and
limited areas where they have certain geologies that cause challenges for groundwater. That’s just
not true across the state.”


Susan Rodriguez doesn’t care how it gets resolved. She just wants to make sure she and her family
have water once the irrigation pumps start back up in the summer.


“My oldest son, he hears a lot and he watches the television, and he was having nightmares that
people were coming in and taking him and his sister away. Taking them out of their home, because
we didn’t have water. That was really hard.”


(sound of water running)


In the few months left until the growing season, when irrigation starts up again, Susan Rodriguez is
storing water. Her friends at work bring her milk jugs and orange juice containers that she fills from
her well while she still has water.

An international group that monitors the health of the Great Lakes is working on a report that
they hope will help policymakers manage the waters in the basin. The Great Lakes Radio
Consortium’s Annie MacDowell reports on a public hearing that took place in Chicago:


Concerned groups responded to a report that came out two weeks ago by the International Water
Uses Review Task Force. The International Joint Commission appointed the task force to
provide an update on developments that have taken place in the basin since the Commission’s
2000 report.


Noah Hall is from the National Wildlife Federation’s Great Lakes Office. He says he’s
concerned the task force’s report does not emphasize how serious threats to the Great Lakes have
become.


“The report could mislead the public or interested policy makers and lull policy makers into
complacency in terms of the need and the urgency for basin-wide protection for the Great Lakes,
particularly for ground water.”


Hall said ground water depletion is causing problems in the communities around the Great Lakes
Basin. Other criticisms of the report were its failure to look toward the future on issues like
climate change and water diversion. The U. S. Chairman of the IJC says the Commission will
study all the public’s comments at a retreat and write their official report within two to three
months.

Ijc to Study Lake Superior Water Releases

An international watchdog group hopes to study the effect of water flowing out of Lake Superior on the rest of the Great Lakes. It is thought that by controlling water from Superior, scientists can better control damaging level fluctuations in the other lakes. The Great Lakes Radio Consortium’s Mike Simonson has the story:

Record high lake levels in the mid-1980’s caused extensive erosion, and below normal levels the past three years have forced ships to carry less cargo, to avoid running aground. The International Joint Commission’s Frank Bevaqua says this begs the question: Is the flow of water out of Lake Superior being handled correctly?

“There’s also the communities along the shoreline that may be susceptible to flooding and erosion and the recreational use of the lakes, particularly by boaters. And then there’s the environmental impact, which is probably the area in which we have the least precision in terms of what we know.”

The IJC is asking Washington and Ottawa to pay for a three-year study of the effect water flowing out of Lake Superior has on the other Great Lakes.

The Soo Locks and Saint Lawrence Seaway are opening to higher lake levels and mild ice conditions, making for an easier start to the commercial shipping season. The Great Lakes Radio Consortium’s Mike Simonson has the story:

Lake levels have been low for the past four years, and the latest numbers from the U.S. Army Corp of Engineers indicate this new season will start with three of the five Great Lakes below average.

February numbers show
Lake Superior is 6 inches below normal, Lakes Michigan and Huron are 7 inches below the average since they started keeping records in 1918. Those numbers are 6 inches better than a year ago. Duluth-Superior Port Director Davis Helberg hopes this is a trend.

“This is cyclical, they will rebound. History tells us that they always do. And I hope we’re at the bottom of the trough but so far this winter hasn’t showed much promise of starting to get back to have the pendulum swing the other way. We just have had such a wimpy winter.”

Lake Erie is at its normal level, while Lake Ontario is 3 inches above normal.

Public Water Systems in Need of Funding

New Bottling Plant Stirs Water Debate

Is Great Lakes water for sale? That’s the issue on the table in Michigan right now, where the Perrier Group of America has begun construction on a 100 million dollar water bottling operation. Last year, government officials in Wisconsin rejected a similar proposal from Perrier. The Michigan plan has sparked local opposition and more. The start of the plant’s construction has given birth to concerns about whether groundwater in Great Lakes states should be considered part of the Great Lakes water basin. And if it is, some question whether it should be for sale. The Great Lakes Radio Consortium’s Matt Shafer Powell reports:

Eight Mile Road in rural Mecosta County, Michigan is one of the area’s busier roads, one of the few ways to get to the interstate. It’s surrounded by thousands of acres of farmland. And at its peak, you can see the Little Muskegon River Valley as it stretches for miles across this point where Michigan becomes Northern Michigan.


(sound of construction)


When Perrier Group Project Manager Brendan O’Rourke saw this stretch of Eight Mile Road, he knew that it would be the perfect place for Perrier’s new Ice Mountain spring water bottling operation.


“Clearly, it’s a beautiful place to live and work, it has abundant natural spring water, the highway system allows for easy access to the marketplace, there’s an available work force and there’s high quality spring water.”


But local resident Terry Swier rarely uses Eight Mile Road anymore. She says it upsets her too much to see the walls of the Perrier plant rising out of what was once a cornfield. Swier is president of the group Michigan Citizens for Water Conservation, a group that formed out of citizen opposition to the plant. Since December, Swier says her group has attracted more than 12-hundred local residents. Most of them are concerned about how local streams, rivers and lakes will be affected by an operation that plans to pump more than 700-thousand gallons of water a day from the ground. But despite her efforts to stop the plant’s construction, work has continued and the plant should be ready to begin operation next Spring.


“It’s just very frustrating how they have the arrogance to say that ‘we can proceed.’ It’s like not even paying attention to the people who are here in the area.”


Perrier officials insist the company has made every effort to listen to local residents and address their concerns. They say they’ve done studies that show the environmental impact will be minimal. And they say the extra 600-thousand dollars a year in tax revenue the plant will generate will go a long way in Mecosta County. Local government officials agree. But Mecosta Township Supervisor John Boyd says he’s more excited by the possibility that Perrier may bring up to 200 new jobs to the area.


“I’ve been to meetings and they say ‘Well, what’s the tax base, what’d you gain on the tax base?’ and I say ‘Hell, I ain’t even looked at it’, because basically, we’re looking for good jobs that sustain people, that will let our kids stay here, stay in the community, and last, we’re looking for a business that will be here tomorrow when we’re gone.”


But construction of the plant and local opposition to it are only the starting points for an issue that has reached far beyond the farmlands of Mecosta County. That’s because the natural springs that lie beneath the ground there feed into the Little Muskegon River, which in turn, feeds into Lake Michigan. Of primary concern to critics is a federal law that requires the approval of all eight Great Lakes governors for any water diversion from the Great Lakes basin. In September, Michigan’s attorney general concluded that the groundwater in Mecosta County should indeed be considered Great Lakes water, and its sale should be approved by the governors. Michigan’s Governor John Engler, though, disagrees on both points and has even offered Perrier nearly ten million dollars in tax breaks. That’s something that frustrates Keith Schneider, of the Michigan Land Use Institute.


“If states are approving diversions of Great Lakes water, they need to consult each other. And the reason they need to consult each other is because we sit on the largest source of fresh water on the planet and this resource is getting ever more valuable. I mean we’re essentially the Saudi Arabia of water here.”


If it’s proven nothing else, the controversy over the Perrier plant has exposed the lack of solid, enforceable groundwater policy throughout the Great Lakes. But in Michigan, that may be changing. In the state capitol of Lansing, various legislative and environmental groups have already begun to unveil their own water control packages—they include everything from the abolishment of tax breaks for companies that bottle water to mandatory assurances that local water quality won’t be sacrificed by those companies. And some groups are calling for a law that would require companies that sell water to pay royalties in the same way that oil and gas companies do now. If it’s ever passed, such a royalty would put a definitive value on water as a natural resource. For the Great Lakes Radio Consortium, I’m Matt Shafer Powell in Mecosta County, Michigan.

Hope for Great Lakes Water Levels

Long term climate projections predict conditions will be right to at least temporarily stop the decline in Great Lakes water levels. The Great Lakes Radio Consortium’s Lester Graham reports:

NOAA’s Great Lakes Environmental Research Laboratory is looking at how this winter’s climate might affect the lakes’ water levels.

Long-term climate projections predict conditions will be to at least temporarily stop the decline in Great Lakes water levels. The Great Lakes Radio Consortium’s Lester Graham reports.


Lakes Superior, Michigan, Huron, and Erie are all at their lowest levels in 35 years. But, officials at the National Oceanic and Atmospheric Administration -or NOAA– say its climate outlooks for this winter indicate there’ll be a normal amount of precipitation and well below normal temperatures. Cold weather means more ice cover on the lakes, and that prevents some evaporation. Cynthia Sellinger is a hydrologist at NOAA’s Great Lakes Environmental Research Lab.


“So NOAA’s forecast, saying that we’ll have below normal temperatures means that we may have a decent ice cover and we may not have winter evaporation. So, if that happens and if we get a decent snow pack, we may not decline anymore.”


But, the experts say it’s still too early to say whether climate will change enough to reverse the lower water level trend on the Great Lakes. For the Great Lakes Radio Consortium, I’m Lester Graham.

Quebec Considers Stricter Water Law

Canadians are looking at new measures to ban the export of water. The Great Lakes Radio Consortium’s Lester Graham reports.


If it’s passed, legislation in Quebec would prevent the export of water from that province. In a report in the newspaper Le Journal de Quebec, the Environment Minister noted that the North American Free Trade Agreement already bans shipment of water by tank, but since the term “tank” is not defined in NAFTA, the Minister feels Quebec should define clear policy. Under the measure, Quebec would still allow the sale of water bottled in containers of less than 20 liters, about the size of a water cooler jug. It would not allow any large vessels or trucks to carry water away and would also ban piping the water out of the province. Canada has been especially sensitive to water issues since President George Bush suggested earlier this year Great Lakes water could be shipped to more arid parts of the U.S. For the Great Lakes Radio Consortium, I’m Lester Graham.
