Biologists are asking people to keep their eyes peeled for
another potential invader into the Great Lakes. A Chinese mitten
crab was found in the St. Lawrence River last fall. The Great Lakes
Radio Consortium’s David Sommerstein reports:


Scientists aren’t sounding the alarm yet. One Chinese mitten crab found near Quebec City doesn’t constitute an invasion. But if they reproduce, the critters could spread quickly.


David MacNeill is a fisheries specialist with New York Sea Grant. He says one was found in Lake Erie in the 1970s, but didn’t proliferate. The mitten crabs spawn in salt water, so they don’t really threaten the upper Great Lakes. But the St. Lawrence River may be better habitat. Regardless, MacNeill says the discovery highlights problems with foreign ships exchanging ballast water before they enter the Great Lakes system.


“Inside ballast tanks on ships, they’re like giant tidal mud flats. When you empty all the water out, there’s this large mud layer. Some of these organisms can burrow into the sediment which is what the mitten crabs do.”


In January, the Coast Guard conceded its ballast discharge rules don’t always work. It said it must find new ways to keep foreign invaders out of the Great Lakes.

River Otters on the Rebound

  • Now that the river otter's population is recovering, some worry that they are plundering fish farms. The proposed solution to this problem is stirring up some debate. (Photo courtesy of the U.S. Fish and Wildlife Service)

There have been many wildlife success stories in the region. For instance, the numbers of white-tailed deer and Canada Geese have rebounded so strongly that many consider them pests.

There have been many wildlife success stories in the region.
For instance, the numbers of white-tailed deer and Canada Geese
have rebounded so strongly that many consider them pests. Now,
another animal is being added to that list. The Great Lakes Radio
Consortium’s Bill Cohen reports on the rebound of the river otter:


In the late 1980’s river otters were so rare in Ohio that wildlife officials imported 123 of the animals and released them along rivers and streams. Now, it’s estimated that Ohio has more than 4,000 river otters. Dave Scott helps track the Ohio numbers for the Natural Resources Department.


“River otters are a really neat success story. And like some other wildlife things, they’ve done better than anticipated.”


In fact, so much better that the otters in Ohio are now being blamed for eating up fish in stocked ponds and in farm lakes where fish are raised for sale. That’s why wildlife officials are now proposing a trapping season here next winter. Trappers value river otters for their fur and back the idea of a trapping season but animal protection activists oppose it. They say the foothold traps that are used are inhumane.

Study Sparks Concerns Over Airplane Water

  • The EPA has found that some of the water served on airplanes is contaminated, and are advising people to be cautious. (Photo by Lester Graham)

New data suggest you might want to think twice before
drinking coffee or tea on an airplane. The Great Lakes Radio
Consortium’s Christina Shockley explains why:


The water on airplanes is tested by the Environmental Protection Agency. Recently, researchers found water that contained coliform bacteria on about one in six of the planes they tested.


The bacteria is usually harmless, but can signal the presence of other, more dangerous organisms.


Cynthia Bergman is with the EPA. She says there’s no need to panic, but concerned passengers should choose other options on board.


“Canned or bottled beverages or bring bottled water onto the flight, and they shouldn’t be shy about asking the flight attendant if the water used for the coffee or tea was made with bottled water, or if it was brought to a boil.”


Bergman says the EPA has not seen any major outbreaks of illness from airplane water. She says symptoms could include nausea and stomach pains. Researchers don’t know yet where the bacteria is coming from, but twelve major airlines have agreed to test the water and disinfect their planes more frequently.

New Agreement With Large Animal Farms

Environmentalists don’t like a new agreement between the U.S. Environmental
Protection Agency and the livestock industry. It will give some livestock
farms limited immunity from environmental laws while the EPA measures
pollution on their farms. The Great Lakes Radio Consortium’s Tamara Keith reports:


Animals at so called “factory farms” produce a lot of manure. As it
decomposes it lets off a cocktail of gasses, which can contribute to smog,
and health problems, such as asthma. But, federal regulators say they don’t
have an accurate way of estimating emissions from these farms.


Under a new EPA agreement, some livestock operations will work with federal
regulators to monitor emissions. The farms allow air quality monitoring, and
in exchange, the EPA will agree not to sue them for environmental violations
during the 2 year program. That’s where the problem arises, says Andrew
Hanson, with Midwest Environmental Advocates.


“The way government is supposed to work is that it’s supposed to
protect you from air pollution, not enter into deals that allow facilities
to continue to pollute without threat of enforcement.”


The Environmental Protection Agency will accept public comment on the
agreement, until March 2nd.

St. Clair Erosion Lowering Lake Levels?

  • A report finds the erosion in Lake St. Clair is causing Lake Michigan and Lake Huron water levels to drop. (photo by Jere Kibler)

Transcript

A new study says erosion in the St. Clair River has caused water levels to drop on Lakes Michigan and Huron. The Great Lakes Radio Consortium’s Lynette Kalsnes has more:


W.F. Baird and Associates is a coastal engineering firm. They recently conducted a study that found that water levels dropped on the two Great Lakes by eight to thirteen inches over the last forty years. Rob Nairn is the study’s lead author. He says that’s about twice as much as authorities thought.


“The outlet to Lake Michigan/Huron, which is the St. Clair river, is in fact expanding. The analogy would be if you had a drain hole in a bathtub, that drain hole is getting bigger, and more water is going out. And as more water goes out, the lake level drops.”


Nairn says the erosion may be caused by dredging, sand mining, or shoreline protection measures that prevented new sediment from getting into the water.


Several environmental groups say the lower water levels could hurt shipping and boating, and damage natural habitats. They’re calling for the U.S. and Canadian governments to stop the reported water loss.


The International Joint Commission says it can’t confirm the report, but it plans to take a closer look at the study’s findings.

Living Entirely Off the Grid

With no power lines in sight, one western Pennsylvania couple lives pretty much like the rest of us. The Great Lakes Radio Consortium’s Ann Murray has this story of a home “off the grid”:

Transcript

With no power lines in sight, one western Pennsylvania couple lives pretty much like the rest of us. The Great Lakes Radio Consortium’s Ann Murray has this story of home “off the grid”:


Ted Carns is busy hanging art in the foyer of his house. While he holds a picture in place against the wall, he plugs in an electric drill.


(sound of drill)


Ted and Kathy Carns’ entire two-bedroom house uses electricity powered by the sun or wind. Their rustic stone and plank home sits on top of a steep wooded hill, miles from the nearest neighbor.


“There’s no water, there’s no soil, there’s no public utilities up here. So everything that we designed, you have to keep in mind, was done in this harsh condition.”


It’s taken the Carns twenty years to design and expand their alternative energy system. Ted, a self-described scrounger and handyman, has found many components through flea markets and friends. In fact, Kathy says their off-grid system began with a gift of shoebox-sized batteries.


Kathy: “Somebody gave us a bunch of batteries-nickel cadmium batteries. And then we started thinking about how to recharge the batteries. Thinking wind. The windmill came first.”


Ted: “It took me eight climbs to install the new windmill, I had a different one up there. The bottom of the tower I built.”


Murray: “How tall is that?”


Ted: “Seventy-six feet.”


(sound of chimes)


The metal tower now looms over the house, outbuildings and organic garden. As the wind whips the chimes at its base, the turbine blades whirl and drive an alternator to generate electricity. The electricity is stored in a bank of batteries.


Murray: “Is the wind consistent here?”


Carns: “Winter good. Summer not. Then in summer the solar panels kick in. So it just sort of balances out.”


The Carns’ rooftop solar panels accept sunlight into silicon chips and convert the light into electricity. Because it’s sunny today, Kathy can run their specially manufactured clothes washer with solar energy. First, she pushes a button on the living room wall and a red light starts to blink. The light indicates that stored electricity is being converted from a DC to AC current.


“That means the house is on 110 power. Turn the water on and then just… It’s on.”


The Carns also vacuum when the sun shines or the wind blows. They run their TV, stereo and lights off 12-volt DC batteries, much like a car. They heat their water with solar energy in the summer and wood in the winter. And warm their house with a wood stove. They also capture air from underground and use it to refrigerate food and cool their house. All told, Ted and Kathy have spent about 3,000 dollars to upgrade their alternative energy system. Ted says, except for burning wood, the system is nonpolluting. He believes it’s also pretty much hassle free.


Carns: “There’s no inconvenience that we’ve seen… There’s maybe two or three days that we don’t have ample hot water. The nice thing about that is that it – you never stop appreciating the conveniences because periodically for a very short time sometimes you have to do without.”


Perez: “More and more people are discovering that they can power their homes and small businesses using solar and wind.”


Richard Perez is the founder and publisher of Home Power Magazine. Perez says states are doing far more than the federal government to encourage the residential use of renewable energy.


“There are tax credits, there are rebates, there are buy-downs. Every state has a slightly different scheme but most states have some sort of financial incentive for installing small-scale renewables in your home.”


Perez says homeowners don’t have to wait wait for government support to set up a system. Ted and Kathy Carns agree.


(sound of plates and silverware)


As the couple gets ready for dinner, Kathy says they want to inspire the many people who come to see how they live off-grid.


“We have a friend who has a solar lawnmower now. We have friends in Philadelphia that took some solar panels; it’s not their total system, but it’s a little part of their system. If we get enough company and enough people have been here, it sort of branches out, and goes off.”


An estimated 180 thousand households in the United States generate some or all of their own electricity. But alternative energy systems aren’t for everybody. For people who are downright afraid of technology or inconvenience, life off the power grid isn’t a real option just yet.

How Far Will Dow Chemical Cleanup Go?

For years, a big chemical company has been negotiating
with government officials on cleaning up an area contaminated with dioxin. Environmentalists say Dow Chemical has used its power and influence to drag out the talks.

For years, a big chemical company has been negotiating
with government officials on cleaning up an area contaminated
with dioxin. Environmentalists say Dow Chemical has used its
power and influence to drag out the talks. The chemical company
has agreed to plan for some kind of clean-up… but it’s still
not clear how far that clean-up will go. The Great Lakes Radio
Consortium’s Rick Pluta reports:


Dow Chemical is a huge employer in Michigan, it employs almost 60 thousand people, not including outside suppliers. In a state that has lost a lot of manufacturing jobs, a big company like Dow is important. The state of Michigan has been negotiating with Dow for nearly a decade over cleaning up dioxin downstream from the company’s big plant in the central part of the state. Just recently Dow and the state struck a deal on the next phase of coming up with a clean-up plan. But it’s not clear how long it will take to design the plan and it’s not clear exactly how far the plan will go to clean up the contamination.


The people who live in the floodplain of the Titabawassee River, downstream from the Dow Chemical plant in Midland, Michigan, say they’ve waited long enough for a cleanup plan. Almost a decade has passed since dioxin was first discovered in the river sediment.


(sound of river)


At Immerman Park in the town of Freeland, downriver from Dow, signs dot the riverbank. They warn parents to keep their children from playing here, because there’s dioxin in the soil.


(sound of hand-washing)


An earlier agreement with the state led Dow to put handwashing stations up here for children to clean up after playing in the dirt. Mary Whitney lives nearby. She says the sinks and faucets in the hand-washing stations are too high and too complicated for children to use, and they’re located too far from the banks of the river. She doesn’t think the kids are getting the dioxin contamination off their hands let alone off their shoes and clothes. She says it’s typical of how the dioxin question’s being handled in Michigan.


“It’s like, well, let’s do a little bit to show we’re doing something, but let’s not maybe address the whole issue. We’ll do just a little but to keep the peace and to keep everybody from not getting so much up in arms. But I think, they’re trying to do, Dow is, trying to do some things to help. But it’s just putting a little Band-Aid on the whole issue. It’s not fixing the main problem.”


For decades one of the by-products of the chemicals Dow produced was dioxin. It’s believed dioxin has been in the soil around Midland since the early 20th century. The fact that dioxin contaminated the sediment along the river downstream was only discovered within the last decade.


Studies have linked dioxin to health problems, including cancer and damage to the nervous system. The state says dioxin has spread to the environment round the Titabawassee River to the point that it issued warnings to hunters to limit how much wild game they eat from the area. That’s because the state says deer, squirrels and other game might be contaminated with dioxin.


Dow and its supporters say the risks posed by dioxin are being overstated. Dow officials say there’s no evidence that the dioxin levels in the Titabawassee floodplain pose a threat to the public health. Dow researcher Jim Collins says the company has six decades of research on employees who’ve been exposed to high levels of dioxin, and the worst health effect is a mild form of chloracne in some of the company’s employees.


Chloracne is the skin condition that disfigured Ukraine’s president, Victor Yushchenko, after he was poisoned by a large dose of dioxin.


“We’ve studied heart disease, diabetes, immunologic effects, reproductive effects, and cancer. And other than some increased risk of chloracne in these workers, we find no health effects that have been related to dioxin exposures.”


Backers of the company say critics should be careful about calling for penalizing Dow. Janee Valesquez is the the local economic development group “Midland Tomorrow.” She says Dow’s impact on the local economy amounts to almost a billion dollars a year.


“So Dow is absolutely… an anchor for mid-Michigan.”


Businesses and workers don’t want to damage relations with the chemical giant. Jim Ballard is an economist at Michigan State University. He says there is some risk that Dow could abandon Michigan. Texas is the new home of the chemical industry, he says, because energy’s cheap and it doesn’t burden industry with a lot of environmental regulations.


“I think Dow might consider leaving if they felt the business regulatory climate in Michigan was excessively onerous. On the hand, it would be very costly for them to leave. They’ve got a large investment in infrastructure and human capital in the Midland area, and to reverse would be a decision that I’m sure they would not take lightly.”


But critics of how the dioxing clean-up has been handled think the economic concerns should not be more important than the health risks to people who live nearby – people such as Mary Whitney. She and others filed a lawsuit seeking a lifetime of medical tests paid for by Dow. That case is before the state Supreme Court. Whitney says she’s afraid a cleanup plan will get bogged down in talks, or delayed by studies.


“We want them to clean it up. Take responsibility for what they’ve done and clean it up and make it safe for all of us. Now I’m not sure what all that would entail. Surely maybe dredging the river to make it deeper. Shoring up the shores, so it doesn’t flood any longer. And fill in the yards with clean soil. And that’s going to be a big thing to do.”


Many critics of the state’s handling of the dioxin clean-up believe anything less than an extensive clean-up is putting business and jobs ahead of the health of the people in Midland and downstream along the Titabawassee River.

The big environmental groups are assessing President George W. Bush’s record on the environment. Mostly, they’re giving him poor marks. But after the Bush win in November, the real question is whether enough people care about the low rankings. The Great Lakes Radio Consortium’s Lester Graham reports:


With the country at war, a lot of people note President Bush has bigger issues than the environment to address. Greg Wetstone is a spokesperson for the environmental group, Natural Resources Defense Council. He says the Bush administration has been dealing with environmental regulations – quietly dismantling them.


“I think there has been a very concerted effort by the Bush administration to make these changes happen in a way that does not receive much public scrutiny.”


Wetstone says the NRDC’s most recent report on the Bush administration might not cause policy changes right now, but it does serve a purpose.


“This report, which is really an effort to document what’s happening because, you know, the day will come when we’re going to need to go back and try to fix as much of this as possible.”


And the environmental group says once the people realize the damage that’s being done to the environment, they’ll want it fixed.

Data suggest that this region continues to lose wetlands despite pledges
from politicians to the contrary. The latest evidence comes from one state
in the region that has some of the toughest laws on the books. The Great
Lakes Radio Consortium’s Mark Brush has more:


After looking at wetlands data from 1994 to 2003, the Minnesota Department of
Natural Resources found that overall the state has lost close to 5,000 acres
of wetlands. This despite the fact that the state has a policy of “no net
loss of wetlands.”


Julie Sibbing is with the environmental group the National Wildlife
Federation. She says states like Minnesota need more than strong laws to
stop wetland destruction:


“You can pass really good state laws to protect wetlands, but if you don’t
adequately fund those programs and if you don’t have the political will to
get the people on the ground and give them the mandate to enforce the law,
you’re really not going to get anywhere.”


Sibbing says to effectively enforce their laws, states need to invest more
in monitoring programs that closely track what’s actually happening on the
ground.

Large expanses of open land often surround airport buildings and runways as noise buffers. Now, at one airport in the region, there’s a plan to put that land to use. The Great Lakes Radio Consortium’s Christina Shockley reports:


When Ryan Mccue was a city official in Milwaukee, he says he took call after call from residents complaining that animals were running loose in area parks. The problem was dog owners weren’t keeping their pets on leashes. Now Mccue thinks he’s come up with a solution: set up a dog exercise area on land unlikely to be used for anything else.


“The airport has a lot of land that’s vacant. And it’s a great spot for it. There aren’t very many neighbors around the airport so the dogs barking won’t disturb any neighbors.”


If aproved, the exercise area would be established on land owned by Mitchell International Airport near Milwaukee. He says the 27 acres would be fenced in and kept separate from the airport
facilities. Mccue says, so far, the airport and the FAA are supportive of the plan. And if it’s approved, he says it could be used as an example of how other airports can make use of their open space.
