The Inspector General for the Environmental Protection Agency
says the agency needs to improve its air toxin monitoring system.
A new report says there are no monitors in 45 out of 50 areas where
cancer risks are highest. The Great Lakes Radio Consortium’s Celeste Headlee reports:
The greater Chicago area is at the highest risk for cancer from air toxins in the Great Lakes region, though residents of big cities in all of the Great Lakes states are at an elevated risk.
The Clean Air Act lists nearly 190 hazardous air pollutants the EPA must regulate. The EPA Inspector General’s report says many high-risk areas have monitors but not within the specific area where people are most vulnerable.
Jim Pew is an attorney with the activist group, Earth Justice. He says it’s important to construct more monitors, but it’s more important to act on the data the EPA already has.
“It’s not a lack of information that’s stopping EPA from acting to get these risks down, and it’s not an impossibility, there are known ways that these problems can be addressed, it’s a lack of will. The agency just doesn’t want to do it.”
Officials with the EPA say they generally agree with the inspector general’s findings.

A recent study indicates expectant mothers who are exposed to
air pollution see damage to the genetic make up of their newborns.
That might increase the babies’ risk of contracting cancer later in
life. The Great Lakes Radio Consortium’s Lester Graham reports:
The expectant mothers were asked to carry air monitors in backpacks to see how much they were exposed to air pollutants. The Columbia University researchers chose 60 mothers in low-income neighborhoods. Dr. Frederica Perera is chief author of the study.
“All of our mothers in the study were non-smokers. So, the primary source of these pollutants in air would be things like motor vehicles, emissions from residential heating units, burning fossil fuel and also from power plants located even fairly far away.”
It’s the fist study to make a connection between air pollutants causing genetic changes in the womb that could increase cancer risk. Earlier studies by the researchers already revealed greater prenatal exposure to air pollution caused lower birth weights and smaller heads in newborns.

The federal government is adding 17 substances to its list of cancer-causing agents. Some of them are causing concern within the medical profession. The Great Lakes Radio Consortium’s Lester Graham reports:
For the first time, the National Insitute of Environmental Health Sciences has listed viruses in its Report on Carcinogens. Hepatitis B and hepatitis C as well as some viruses that cause sexually transmitted diseases have been added as cancer-causing. Other substances new to the list are some compounds found in grilled meats, a number of chemicals found in textile dyes, paints and inks, and x-rays. Dr. Christopher Portier is the agency’s Director of Environmental Toxicology Program.
“The medical profession is a little concerned about us listing x-rays. They’re afraid people will stop getting medically necessary x-rays because of the concern for cancer.”
But Portier says the best bet is to discuss those concerns with your doctor. For the record, the government now recoganizes 246 substances as “known” or “reasonably anticipated” to be cancer-causing agents.

Diversion of water from the Great Lakes is a controversial issue. Many worry that diversion could affect life in the ecosystem. Others worry about obtaining sources of fresh water for drinking. (Photo by Brandon Bankston)
Great Lakes governors and their counterparts in Canada are working on a legal agreement called Annex 2001. The document will determine how water from the Great Lakes will be used and who gets to use it. Controversy has already erupted over the possibility of one city’s bid for the water. The city is looking toward the completed Annex for guidance. The Great Lakes Radio Consortium’s Christina Shockley reports:

Great Lakes governors and their counterparts in Canada are working
on a legal agreement called Annex 2001. The document will determine how
water from the Great Lakes will be used and who gets to use it. Controversy
has already erupted over the possibility of one city’s bid for the water.
The city is looking toward the completed Annex for guidance. The Great
Lakes Radio Consortium’s Christina Shockley reports:
Dan Duchniak says he’s an environmentalist.
“We have the low-flow showerheads in our house, we have the low-flow faucets, we have the high-efficiency washers and dryers, our kids know about those, you know, they think they’re fun.”
But Duchniak is in the middle of a bitter fight with other environmentalists and officials over his area’s largest natural resource: water from Lake Michigan. Duchniak is the water manager for the City of Waukesha, Wisconsin. It’s just west of Milwaukee. Waukesha is only about 20 miles from the Lake Michigan shore. Right now, Waukesha gets its water from wells that tap an aquifer deep within the ground. But Duchniak says the wells won’t sustain the long-term needs of the city.
“As the water levels drop, the water quality degrades, and what happens is we’ve seen an increase in different water quality parameters, one of those being radium.”
And radium is a health problem. In very high doses, radium can cause bone cancer. To solve its water problems, the City of Waukesha might ask for access to Lake Michigan water. But even though the community considers the lake part of its back yard, there’s a major problem. Even though it’s close, Waukesha sits outside the Great Lakes basin.
That means the area’s ditches and streams drain away from the lake. Rain water runoff and treated water from the sewer system flow toward the Mississippi River Basin. The governors and premiers might include a rule in the Annex 2001 that says communities sitting outside the Great Lakes basin must return treated water to the lake, if they use it.
Engineers who study water in the area say Waukesha could make the case that the city is already using Great Lakes water. That’s because the city’s wells tap into water beneath the surface that supply water to Lake Michigan. But environmentalists say that argument isn’t going to fly. Derek Sheer is with the environmental group “Clean Wisconsin.” He says Waukesha would be pumping a lot more water directly from the lake than the underground aquifer would replace.
“They’re not returning 13 million gallons of water back to the Great Lakes by any stretch of the imagination.”
But the city of Waukesha knows that if the finalized Annex 2001 looks anything like the early drafts, the city would have to return most of the water it uses back to the lake. Waukesha’s water manager, Dan Duchniak says that could be done in a combination of ways. The city could pump it back to the lake, pump it to a nearby stream that flows to the lake, or stop using the ground water completely and let it flow back to the lake.
People on both sides of the water issue seem to agree on one thing: because of the huge amount of water in the Great Lakes system, and its natural ebb and flow, the amount of water the City of Waukesha would take would not harm the Great Lakes’ ecosystem. Even if it’s not pumped back.
Art Brooks is a professor at the Center for Great Lakes Studies at the University of Wisconsin-Milwaukee.
“The amount of water they intend to withdraw would probably lower the level of Lake Michigan on the order of a millimeter or so, probably less that five millimeters per year.”
But it’s not just Waukesha that has environmentalists worried. Professor Brooks and environmentalist Derek Sheer say if Waukesha gains access to Great Lakes water, it could set a dangerous precedent. Sheer doesn’t want other states and countries to start withdrawing Great Lakes water.
“If Waukesha and Arizona and Georgia and all these other places start pumping large amounts of water out of the basin, we could see a dramatic lowering of the water in the lakes.”
The city of Waukesha says it needs the water and would abide by whatever the Annex 2001 agreement sets down. And Waukesha’s water manager, Dan Duchniak, says that includes what it determines about return flow. He says arguing about the issue right now is a waste of time, since the Annex isn’t done. Beyond that, Duchniak says Waukesha is part of the Great Lakes system, and is not about to suck the lakes dry.
“Lake Michigan is in our back yard. We can see Lake Michigan from here. We’re not that far away from it.”
The experts say Waukesha would only be the first in line to ask for Great Lakes water. With suburbs sprawling away from the big cities on the lakes more and more towns will be eyeing the Great Lakes when demand for water exceeds their underground supplies.
A draft of the Annex could be ready this year, but it will most likely go through a lengthy series of votes before it becomes law.

For years, a big chemical company has been negotiating

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.

Three major cosmetics companies have announced they’ll stop using certain chemicals that have been linked to liver and kidney damage, and reproductive system problems. The Great Lakes Radio Consortium’s Erin Toner reports:
L’Oréal, Revlon and Unilever say they’ll comply with a European Union policy that requires cosmetics companies to stop using chemicals that are suspected of causing cancer, birth defects or impaired fertility. Those banned chemicals include phthalates, which are used in some hair and nail products and fragrances. Bryony Schwan is with The Breast Cancer Fund, the group leading the Campaign for Safe Cosmetics. She says phthalates are just the first step.
“There are a lot of chemicals in cosmetics that are potentially dangerous. We have a lot of chemicals that have not been tested. We have other chemicals that are linked to cancer and reproductive health effects. So removing phthalates is just the beginning.”
The Campaign for Safe Cosmetics is asking all cosmetics companies to sign a pledge to remove all EU-banned chemicals, and replace them with safer alternatives within three years.

A new PVC manufacturing plant is being built in the region, and that has some environmental groups alarmed. The Great Lakes Radio Consortium, Joyce Kryszak reports on efforts to halt production of polyvinyl chloride:
Environmental groups are protesting the construction of a new PVC plant near Buffalo. They say manufacturing PVC releases toxic chemicals into the environment. The group recently released a report highlighting the dangers of PVC and are calling on companies to phase out production of the popular manufacturing material. Mike Schade heads the Citizens’ Environmental Coalition in western New York. The region is home to CertainTeed, a PVC plant that will soon expand to a site along Lake Erie. Schade says it’s a step backward.
“I think it’s outrageous that, given the fact the Great Lakes have seen so many environmental problems, that CertainTeed is coming in and citing a PVC plant right on the lake,” said Schade, “It certainly isn’t my vision for a clean and safe and healthy waterfront.”
Schade says residents near other Certain Teed plants show increased levels of cancer and other serious disease. But company spokesperson Dottie Wackerman disputed the claims. And she says the company’s new plant will have virtually no emissions.

Researchers believe they have found a way to reduce arsenic levels in drinking water. They say, for people to drink water from wells or aquifers, the solution starts at the source. The Great Lakes Radio Consortium’s Jeff Bossert explains:
Chronic exposure to arsenic in drinking water has been linked to a variety of health concerns, including hypertension, cardiovascular disease, and cancer.
Researchers from the University of Illinois collected groundwater samples from 21 wells. They found that the wells with almost no arsenic in the water also contained high levels of sulphate-reducing bacteria, which convert the arsenic into a solid, where it drops out of the water. Dr. Craig Bethke led the study.
“What we’re saying is that if there’s sulfate in the water, then there’s probably sulfate-reducing bacteria active in the subsurface, and that means that a simple field test, which is very inexpensive and very rapid to protect sulfate, could identify safe water sources.”
Bethke says places where aresenic levels are high, sulphate salts, such as gypsum and calcium sulphate, can be injected underground to reduce arsenic levels.
Researchers say this information could prove to be invaluable in places where aresenic contamination is a major problem, including parts of the U.S., Australia, and Mongolia. The researchers’ findings were published in the journal Geology.

Flame retardant chemicals help make our lives safer. The chemicals are designed
to keep plastics and foam from catching on fire. But the flame retardants are
beginning to worry some scientists because these chemicals are turning up in
peoples’ bodies. Sometimes at alarmingly high rates. The Great Lakes Radio
Consortium’s Mark Brush has more:
If you take a look around your house, you can find a lot of things that have
flame retardant chemicals in them. They’re in your television set, the cushions
in your couch, and the padding underneath your carpet. They’re known as poly-bromiated-diphenyl
ethers, or PBDEs. And they’re either mixed in or sprayed on plastics and foam to keep a fire
from spreading.
Five years ago a Swedish study found these chemicals were accumulating in women’s breast
milk. Studies in the U.S. followed, and researchers also found PBDEs in Americans, but at
even higher levels. In fact, Americans have some of the highest levels ever measured. And
over time, the levels have been going up.
(sound of baby)
Meredith Buhalis was one of those people measured in a study by an envrionmental organization
called the Environmental Working Group. Buhalis and 20 other first time moms sent in samples
of their breast milk. When the samples were tested, all of them had some level of PBDEs in
them. Buhalis says when she read the results she didn’t know what to think.
“I guess I kind of read the results and the study was like, ‘Oh, well that sort of sucks.’
I wish I knew more about what that meant. ‘Cause I don’t. You know, they don’t know what
that means.”
Scientists don’t know how or if the chemicals affect human health. And some scientists
think the government and the chemical companies aren’t doing enough to look into PBDEs.
(sound of typing)
In his office at the University of Texas in Dallas, Dr. Arnold Schecter is working on an
article about the flame retardants. He’s been studying toxic chemicals for more than thirty
years. He and some of his colleagues think PBDEs are a lot like another type of chemical…
“It reminds us of PCBs. PCBs structurally are similar to the PBDEs. So there is the worry,
or the concern, that they may have many, if not all, the toxic effect that PCBs have on humans.”
So far the data on PCBs strongly suggest that the chemicals can cause cancer in humans as
well as other human health effects such as damage to the nervous and immune systems. The
companies that manufacture the flame retardants say it’s not fair to compare PBDEs with
PCBs. They say the chemicals are vastly different.
But no one really knows whether the chemicals are similar in the way they affect human
health. That’s because no one’s studied the human health effects of PBDEs.
“Unfortunately, there are no published human health studies and I don’t believe any have
been funded by the federal government to date. Nor by industry, nor by any foundations,
which is a bit different than the situation with PCBs and dioxins years ago when many
studies were being funded.”
Some animal studies suggest that the chemicals can permanently disrupt the hormone and
nervous systems, cause reproductive and developmental damage, and cause cancer. All that
makes scientists such as Dr. Schecter especially concerned about the most vulnerable
population – developing babies.
Because of the concerns, the biggest manufacturer of these chemicals in the U.S. has agreed
to stop making two of the PBDE formulations that were found to accumulate in people. Great
Lakes Chemical says production will stop by the end of this year. The chemicals will be
replaced with another type of brominated flame retardant.
The Bromine Science and Environmental Forum is a trade group that represents companies
that make the flame retardants. Peter O’Toole is the group’s U.S. Director. He says so
far the amount of chemicals found in people doesn’t concern the companies, but the upward
trend does.
“And again, it wasn’t of alarming numbers, but the manufacturer was concerned that these
numbers were going up nonetheless. And they thought it was prudent, and they talked to the
EPA and EPA thought it was prudent if there was some sort of mutual phase out of those materials.”
Dr. Schecter says he commends the company for taking this step. But he says even though these
two formulations will be phased out, the flame retardants are already in our environment now.
He says his research has found high levels of PBDEs by wiping the plastic casing on television
sets, and in the dust found in homes. He says what’s in our homes now isn’t going to vanish,
so we need to figure out how the chemicals get into us, so we can avoid potential health problems.
For its part, the U.S. Envrionmental Protection Agency says large-scale human health studies
take a long time to develop. An agency spokesperson says the EPA first needs to learn how a
person becomes highly exposed. After that, they say researchers will be able to ask the question,
“for the highly exposed people, are there any health effects?”
(sound of baby)
That leaves people such as Meredith Buhalis, with a lot more questions than answers.
“We are thinking of having another baby, and I think I would really like to know more about
PBDEs. I think about it when I think about that.” (to her daughter) “Oh thank you. Hi, baby.
Hi, Zoe.”
The Federal government doesn’t plan to regulate the chemicals anytime soon. But some states
aren’t waiting for more studies. A handful of states have placed restrictions on certain
types of PBDEs. And in other states, legislation is pending.

New research shows that chemicals used to repel food, stains, and water are
sticking just about everywhere else in the environment. They were recently found
in the Great Lakes. But as the Great Lakes Radio Consortium’s Sarah Hulett
reports, their discovery was not a surprise:
The chemicals are called perfluoronated compounds. They’re used in products
like Teflon, Scotchgard, and Gore-Tex. They’ve been detected in animals from
Arctic polar bears to seals and birds in the Baltic.
Matt Simcik is a researcher at the University of Minnesota. His studies turned up
the chemicals in lake trout from all five Great Lakes. Simcik says a likely source
for the contaminants is wastewater treatment plants.
“Because these chemicals are used in everyday use – textiles and carpets and
things. And when you wash your clothes, or wash your carpet, that water gets
into the waste system, and eventually ends up in the lake.”
The effects of the chemicals on humans is the subject of intense debate – but at
high exposures they’ve been linked to problems including birth defects and
cancer .
One of the two known chemicals has been phased out of use. Federal regulators
are looking at the other to determine whether it should be restricted as well.
