There’s an invisible, odorless gas that kills 21,000 Americans every year. We’ve known about radon gas for a long time. But as Mark Brush reports, experts say we’re still a long way from fixing the problem:

Radon gas is found down here…

…in the basement.

Really, it’s all around us. The gas drifts out of the ground from bits of uranium ore. Normally, there’s not enough of it to cause a problem. But it can get trapped in our homes, schools, and offices. We breathe it in. And the gas can cause lung cancer. It’s the second leading cause of lung cancer next to smoking. And if you’re a smoker – you’re even more at risk.

The level of radon gas in this basement is unsafe. More than four times a safe standard set by the EPA:

So a crew of two guys is here to fix the problem.

David Aschenbrenner works for Pro-Tech Environmental in Ann Arbor, MI. He says radon gas seeps up from the ground and makes its way into the house through cracks and holes in the foundation:

“So as the air is rising through the house, the house acts as a chimney. It’s creating what we call the stack effect. And that’s what’s actually pulling the radon in.”

You can’t see it. You can’t smell it. But it’s often there.

“So with the radon piping, and the radon fan, it’s going to create a suction slightly stronger than the house breathing normally.”

They drill a hole in the basement floor – put a PVC pipe into the hole. And fan on the pipe will vent the radon gas outside.
Right now – a lot of people find out about radon when they buy or sell a house. The air is tested and if there’s a problem – it can be fixed.

Bill Field is an epidemiologist at the University of Iowa. He’s studied the health risks of exposure to radiation for decades. Field says these systems work. But even though more people know about the threat of radon gas – there are still more people exposed today than in the past:

“We’re further behind now, than we were 20 years ago with addressing the radon issue, because more homes are being built that aren’t radon resistant than are being mitigated. Each year there are tens of thousands of home that are coming on the market that will hopefully be fixed someday, but they could have been fixed when they were first built.”

Field says new homes should be built to keep radon out. He says simple changes in home construction – changes that would only add $500 in construction costs – would work. He says there should be a federal requirement to build homes this way, since radon can be a problem in every state.

There are some states, counties and cities that have radon resistant new construction written into their building codes – but more than half don’t – and even in the places that do have the code on the books – workers told us that it’s not always enforced – so it’s easy to just skip the requirement.

The National Association of Home Builders says it would oppose any federal requirements to build homes this way. They say radon should be dealt with where there are known hot spots.

There are parts of the country where radon can be bigger problem than in other areas. But it can be a problem no matter where you are. The EPA has a recommended standard for radon gas. It says that homes or offices or schools should be fixed if they have radon levels of 4 pico-curies per liter or more. But Bill Field says sixty percent of the cancers caused by radon were caused at levels below this EPA standard:

“Talk about a safe level of four pico-curies per liter is really a misnomer. It’s like saying it’s o.k. to cross the road blindfolded because there’s only one car coming instead of three. There really is no safe level of radon.”

A recent report by the President’s Cancer Panel evaluated the progress being made on cancer prevention. Exposure to radioactive radon gas is one of the areas where the experts said not enough is being done. And because the problem is getting worse – they’re recommending the government do more.

“You can test your air for radon gas by buying a test kit at your local hardware store. They cost between ten and twenty dollars.”

Coal Power Plants Go Up in Smoke

Many of the plans to build new coal-burning power plants have gone up in smoke. In early 2007, the Department of Energy noted there were 151 coal-fired electric generators on the drawing board. Lester Graham reports since then… nearly a hundred of them have been canceled—or shelved.

Many of the plans to build new coal-burning power plants have gone up in smoke. In early 2007, the Department of Energy noted there were 151 coal-fired electric generators on the drawing board. Lester Graham reports since then… nearly a hundred of them have been canceled—or shelved.

There are several reasons. The recession has tightened credit for building coal-fired power plants. Electricity demand has flattened- partly due to the economy—partly to better efficiency in businesses and homes. Lawsuits blocked some of the coal-burning plants. And some states are requiring power companies to compare the costs of burning fossil fuels to using alternatives such as wind because of concerns about climate change.

Ted Nace is with the environmental advocacy group CoalSwarm. He says he thinks this slow down in building coal-burning power plants is permanent…

“It’s a pretty profound shift in the American economy. And a lot of it’s being driven by economics, but also a lot of it’s still being driven by climate concerns.”

Some new coal-burning power plants did go online last year… but in real terms there was just as much new wind power installed.

Living Without Plastic

  • Cheryl Lohrman victorious after finding a specialty deli that would sell her cheese and put it, plastic free, in her steel tin. (Photo courtesy of Sadie Babits)

We use a lot of plastic. Every year some 30 million tons of plastic in the U.S. from diapers to bottles get tossed in landfills. One woman wants to change those numbers. She’s trying to live her life without plastic. Sadie Babits caught up with her to find out if that’s really possible.

We use a lot of plastic. Every year some 30 million tons of plastic in the U.S. from diapers to bottles get tossed in landfills. One woman wants to change those numbers. She’s trying to live her life without plastic. Sadie Babits caught up with her to find out if that’s really possible.

When Cheryl Lohrmann comes to the grocery store all she sees is plastic. Plastic yogurt containers, cheese wrapped in plastic shrink-wrap, juice bottles, plastic bags. She doesn’t want this stuff in her life. So Lohrmann decided she’d vote with her wallet by refusing to buy anything with plastic.

“We’re at cherry sprouts grocery store in Portland, OR where I’m going to purchase some cheese and some eggs.”

Eggs are no problem. She just puts them in her used egg carton. But cheese is a different story. She has a small steel tin that looks like it belongs with her camping gear – not the grocery store. And Lohrmann has a special request for the guy behind the counter.

“And that is if I get the cheese not wrapped up in plastic but just in this container or maybe you could put this on paper.”

“Aahhh. I don’t think we can do that because it needs to be wrapped up.”

Lohrmann gets that reaction a lot. So she won’t buy cheese here. It means a trip to another shop – this time a high-end specialty deli.

LouAnne Schooler owns this store. She explains to Lohrmann why they use plastic.

“Plastic, it’s the unfortunately simplest choice because we wrap and re-wrap continuously throughout the day and it can’t be left unwrapped and people need to see the cheese so that precludes it from being wrapped in most papers.”

But Schooler says she’s only too happy to help people like Lohrmann who don’t want their cheese shrink- wraped. So she drops the cheese –plastic free – into Lohrmann’s tin.

“That’s a good chunk of cheese. Magical moment here–thanks for letting me do that”

“Sure.”

Lohrmann started going plastic free a couple of years ago after reading Elizabeth Royte’s book Garbageland. The author tracked her trash to find out where it ended up. The chapter on plastic struck a nerve with Lohrmann.

“I think it’s been taken too far when you have toothpicks individually wrapped in plastic. You know you just start to think is that really necessary given the fact that this is such a toxic material that doesn’t have high enough recycling rights to really justify having it.”

Lohrmann also gets miffed that you end up paying for plastic three times. You pay for it at the grocery store and again to have it hauled to the landfill. Finally, she says we pay for it environmentally – plastic doesn’t disappear. So you might think it’s a little nuts to even think about living a life free of plastic. Lohrmann gets that.

“It is hard right now to feel like you can maneuver to get whatever you want without plastic.”

“Ok, so on a scale of one to ten–ten being plastic free–where are you?”

“I would say probably a nine.”

That’s a nine when it comes to buying groceries. Because let’s face it. Plastic is everywhere even in Lohrmann’s home. There’s her computer, picture frames, even the parts on her bike. She realizes going plastic free is nearly impossible but she’s willing to try to send a message especially to businesses that we need to reduce the amount of plastic in our lives.

Safety Awards for Big Polluters

  • Some say that workplace safety awards promote complacency. (Photo courtesy of the NIEHS/DOE)

The companies associated with the two biggest accidents this year both recently got safety awards from the government. Lester Graham reports.

The companies associated with the two biggest accidents this year both recently got safety awards from the government. Lester Graham reports.

The Mineral Management Service announced BP was a finalist for a safety award in May. Then, the Deepwater Horizon exploded, killed eleven men, and spilled –who knows how much– oil into the Gulf of Mexico.

The Mine Safety and Health Administration gave the coal company Massey Energy three safety awards last year. Then the Upper Big Branch Mine exploded. 29 miners died.

In an opinion piece in The Hill , The President of the Steelworkers union, Leo Gerard, argued those awards promote complacency– a sort of ‘see we’re already doing it.’

David Uhlmann is a law professor at the University of Michigan. He served for seven years as Chief of the Justice Department’s Environmental Crimes Section. He says awards can prod companies to do better… but…

“There’s always going to be some companies who cut corners, who put profits before safety, who put profits before their obligations to protect the environment.”

BP was to get its award in May. The safety awards ceremonies were postponed.

Gulf Spill Raises Questions About Imported Seafood

  • Right now, Congress is considering a bill that would give the FDA a lot more authority over imported seafood. (Photo courtesy of the NOAA)

The oil spill in the Gulf of Mexico is looming over the seafood industry. Prices for things like shrimp and crab are going up. It might mean we’ll see even more imported seafood in the coming months. But as Tanya Ott reports, some people are questioning the safety of imported seafood:

Tom Robey runs around like a mad man. Or maybe a mad scientist. His laboratory is the kitchen.

“This is the beginning of New Orleans barbecue sauce for our shrimp dish. So it’s brown garlic and black pepper and rosemary and beer.”

Robey is executive chef at Veranda on Highland in Birmingham, Alabama. His specialty is regional seafood: Louisiana crawfish, Florida crab, Alabama shrimp.

When the Deepwater Horizon oil rig exploded last month spewing oil into the Gulf, Robey shelled out nearly 3-thousand dollars to stockpile 600 pounds of shrimp.

And it’s a good thing, because officials closed some of the fishing grounds. It’s not clear how extensive and long-term the damage to Gulf seafood will be. Early tests don’t show substantial chemical contamination, but monitoring might have to continue for decades. Meanwhile, industry officials expect a shortage of domestic seafood. And other countries are ready to fill the gap.

We already import about 80% of our seafood. But the oil spill is expected to drive that number higher.

Tom Robey says he’ll take seafood off the menu before he serves imports.

“I’m nervous about, like, how that seafood was handled, how it was fed, if it was farmed raised. I mean every day there’s some kind of recall one or another coming from China.”

He may have reason to be nervous.

“I think it’s really a buyer beware issue.”

Caroline Smith DeWaal is director of food safety for the Washington DC-based Center for Science in the Public Interest. She says when state regulators tested imported shrimp they found it was contaminated with antibiotics and other chemical residues that are illegal in the US. Dewaal says there’s evidence some imported shrimp are grown in contaminated ponds.

Supporters of the industry say – while some tests have caught problems – that doesn’t mean all imported seafood is bad.

Norbert Sporns say there’s no need to worry. He’s CEO of a Seattle-based company called HQ Sustainable Maritime Industries. They farm tilapia – mostly in China. Sporns says the US has an international certification process that is rigorous and will catch potential problems.

“Prior to export we are subject to a series of tests. Once a product lands in the United States there are other tests that can be administered by the FDA on a spot check basis, so there are multiple levels of security in place.”

But the FDA only inspects about 2 percent of imports.

Ken Albala is a food historian at University of the Pacific in Stockton, California. He teaches about food policy and environmental issues. He says the cattle industry has been tightly regulated, but:

“Fishing hasn’t been.. And when you’re talking about a several thousand pound cow versus a bass – let alone a shrimp. I don’t see how they could ever begin to inspect consistently what’s coming in from abroad. Definitely not.”

Right now, Congress is considering a bill that would give the FDA a lot more authority over imported seafood. So far, the bill has passed the house and is waiting to be picked up in the Senate.

So – consumers who want to eat shrimp – and boy do we love our shrimp! – are faced with two choices:

Trust that random spot checks find any problems with seafood imports…

Or pay more for domestic, wild harvested shrimp …

And that price could go even higher if the oil spill in the gulf contaminates a good part of the domestic supply.

Challenging the Drilling Ban in Shallow Waters

Some smaller companies want to keep drilling in the Gulf of Mexico. Lester Graham reports… a group called the Shallow Water Energy Security Coalition says its members’ rigs are different than the BP operation that’s polluting the Gulf.

The drillers want the Interior Secretary Ken Salazar to lift the moratorium on drilling in the shallow waters. In an article for Greenwire, Mike Soraghan reports… they’re getting support in letters from members of Congress.

“They’ve got about ten senators that have signed on and about 50 House members, including Ken Salazar’s brother who’s a member of Congress from Colorado, John Salazar.”

The drillers say there’s a big difference between BP’s Deepwater Horizon, drilling at 5000 feet… and the rigs they operate in water less than a thousand feet.

“They would argue that what you’ve heard in the past few weeks from BP officials is, you know, if this was in 200 feet of water, we’ve could have dealt with it a long time ago.”

Interior Secretary Salazar is to send the White House a report on the drilling moratorium by this Friday – the same day President Obama will be visiting Louisiana.

Whooping Cranes Not Hatching

Wildlife experts are trying to bring back a flock of migrating whooping

Wildlife experts are trying to bring back a flock of migrating whooping
cranes in the eastern United States. But there’s a problem. Scientists are
having trouble getting the whoopers to hatch chicks in the wild. Chuck
Quirmbach reports – researchers are taking a closer look at the ten-year-old
rehabilitation effort:

It’s not easy to get whooping cranes to reproduce, but here in Baraboo,
Wisconsin, researchers have had success at getting captive cranes to produce
chicks.

For the last ten years, the Whooping Crane Eastern Partnership has created a
flock of more than 100 whoopers. Researchers hatched the birds
– and trained them to migrate by flying behind ultralight aircraft ….or to
follow adult cranes. The birds now fly between the upper Midwest and
southeastern U.S.

But one of the goals of the Partnership is to get more cranes to raise young
in the wild. So far, only one crane chick has been successfully hatched and
gone on to migrating.

Jeb Barzen is with the International Crane Foundation. He says they can’t
keep supplying the flock with chicks hatched in captivity:

“It’s expensive. it’s expensive in time, expensive in money…expensive in overall conservation effort, because what you put into whooping crane reintroduction you can’t put into other conservation projects at that time. so to be fully successful …you want that population to be
able to survive on it’s own.”

So far, about 16 million dollars has gone into re-introducing whoopers to
the eastern u.s. More than half of that money came from private donors.

The birds’ main summer home is here at the Necedah National Wildlife Refuge
in Wisconsin.

It’s not that the cranes don’t get close to each other. If you watch the cranes here, you can spot single cranes and the occasional couple.

Jeb Barzen pauses to watch two tall white cranes having a territorial dispute:

“Ooh! these birds are threatening each other. that’s a preen behind the wing
threat…that the second bird is doing…so these are not birds of the same
pair.”

Researchers don’t know why the birds are not raising more wild chicks. But
they do have some theories. Even when cranes do make nice and produce an
egg – the relatively young cranes may be too inexperienced to be patient
parents. Black flies may drive the birds off their nest. Or the parents
may be low on body fat and take off to find food.

The crane researchers are gathering data to find out what cranes need for a
successful nesting site. They’re using tracking radios to follow some of the
birds.

Anne Lacy is with the International Crane Foundation. Today she’s driving
around southern Wisconsin listening for the whoopers.

“it’s important to look at what choices they make as a young bird
before they breed…to know how they choose those areas….they need for
water for roosting at night…they need that eventually for nesting.”

This kind of research is being ramped up this spring. That’s because an
independent report raised some concerns about the crane recovery effort.
The report was done by consultants hired by the Whooping Crane Eastern
Partnership. It mentions problems with financial oversight, scientific
coordination, and whether the birds’ main summer home – at the Necedah
wildlife refuge – is the best place for them.

Louise Clemency is with the US Fish and Wildlife Service. And
she is a co-chair of the eastern partnership. She says the crane recovery
effort won’t make any big changes overnight.

“We’re trying to the time to draw the right conclusions so we can
take the right next step.”

Clemency says decisions on the whooping crane experiment could come next
year. In the meantime..she hopes that some crane eggs laid this spring at
the Necedah refuge will hatch.

EPA’s Report on PBDEs

A new report from the Environmental Protection Agency links health problems to flame retardants. Lester Graham reports the EPA finds children are most at risk.

Transcript

A new report from the Environmental Protection Agency links health problems to flame retardants. Lester Graham reports the EPA finds children are most at risk.

Polybrominated diphenyl ethers, or PBDEs, are flame retardant chemicals used in all kinds of household consumer products. Sofas, computers, babies’ funiture. The report finds kids are getting a higher dose of PBDEs. That’s bad because the chemicals have been linked to many different developmental and reproductive health problems.

Arlene Blum is a chemist at the University of California Berkeley. She says the report notes PBDEs migrate from foams and plastics into household dust.

“Eighty to ninety percent of the human dose is from dust. So, toddlers, you know, they crawl in the dust, put their hands in their mouths. So, that’s why toddlers have such a high level at such a vulnerable time.”

The EPA report says the findings of many studies raise particular concerns about the health risks to children.

USDA Guidelines Questioned

  • Professor Paul Marantz says even a small error in the federal food guidelines can have a big public health impact. (Photo courtesy of the USDA)

Some people say the government is partly to blame for America’s obesity problem – because of the federal dietary guidelines. Julie Grant reports on efforts to improve how the government offers nutritional advise to Americans.

Transcript

Some people say the government is partly to blame for America’s obesity problem – because of the federal dietary guidelines. Julie Grant reports on efforts to improve how the government offers nutritional advise to Americans.

You’ve probably seen those colorful food pyramids they put out, the ones that tell you how many servings to have of each kind of food each day. Those recommendations are used by schools, nursing homes, and the federal food stamp program to design menus.

Robert Post works with the U.S. Department of Agriculture, which puts out the food pyramid.

“IT’S THE CORNERSTONE FOR BUILDING HEALTHY EATING PATTERNS. CHOOSING THE RIGHT AMOUNTS OF FRUITS, VEGETABLES, GRAINS, MILK PRODUCTS, AS WELL AS PROTEIN SOURCES SUCH AS MEAT AND BEANS.”

Post says people need to know how to get all the nutrients they need, without over-indulging in foods they don’t need.
That’s why the guidelines also set specific limits on things like salt and fat.

But some researchers think the guidelines actually have the potential to cause harm.

Paul Marantz is professor of epidemiology and population health at the Albert Einstein College of Medicine.
He doesn’t think the guidelines should give specific recommendations about how much fat and salt people should eat.

“THOSE SEEM TO CARRY PRECISION THAT IMPLIES THAT WE HAVE A GREATER DEPTH OF KNOWLEDGE THAN WE ACTUALLY DO, SO PICKING THESE NUMBERS AND REQUIRING THAT PEOPLE HUE TO THESE GUIDELINES IS A PROBLEM.”

Marantz says even a little bit of error in the food guidelines can have a big public health effects.

He and his colleagues wanted to find out the potential impact of past dietary guidelines.

They looked at 1995, when the nutritionists were telling people to avoid fat.

“MOST OF US REMEMBER IN THE OLD FOOD PYRAMID THAT MADE IT QUITE CLEAR THAT THE MOST IMPORTANT THING TO AVOID WAS FAT AND ONE COULD EAT GRAINS AND PASTA AND BREAT AND THE LIKE WITHOUT CONCERN.”

Marantz says Americans did eat more pasta and bread – that added lots of calories, and lots of weight.

His research, which was published in the American Journal of Preventive Medicine, found what Marantz calls a ‘strong correlation’ between the dietary guidelines against fat and obesity in Americans:

“CORRELATION IS BY NO MEANS CAUSATION. WE CANNOT INFER FROM THIS THAT IT WAS BECAUSE OF DIETARY GUIDELINES THAT WE ARE EXPERIENCING THE EPIDEMIC OF OVERWEIGHT AND OBESITY. BUT THE CONNECTION IS STRONG.”

Marantz wants the government to give general advice for healthy eating, but not specific guidelines. He gives the example of sodium. Marantz says no one really knows how much salt is appropriate for each person. But there’s a push to put specific limits on sodium in the new guidelines.

Robert Post of the USDA says anything that gets into the 2010 recommendations will be based on what he calls the Gold Standard of scientific evidence. He says a committee of nutritional experts has been meeting for two years to create the new guidelines…

“WE CAN BE ASSURED THROUGH THIS VERY INTENSIVE REVIEW OF SCIENCE AND THE WEIGHT OF THE EVIDENCE IT PROVIDES THAT THE CURRENT ADVISE ON CARBOHYDRATES FOR EXAMPLE IS BASED ON THE LATEST RESEARCH.”

Post says any recommendations for fat and sodium will also be based on the preponderance of current science. The committee is expected to make its recommendations this summer, and new dietary guidelines should be published by the end of the year.

EPA Coal Ash Plan Criticized

  • The new coal ash clean-up project will take four years and cost 268-million dollars. (Photo courtesy of Brian Stansberry)

More than a year ago – when an earthen wall broke at a power plant in Tennessee, 500-million gallons of toxic coal ash and water were spilled. If you compare it to other environmental tragedies – it was 50 times bigger than the Exxon Valdez spill. Half of the coal ash spill’s been cleaned up, but crews are still working to get the rest of it. And as Tanya Ott reports there are concerns about a new plan to deal with the ash:

More than a year ago – when an earthen wall broke at a power plant in Tennessee – 500-million gallons of toxic coal ash and water were spilled. If you compare it to other environmental tragedies – it was 50 times bigger than the Exxon Valdez spill. Half of the coal ash spill’s been cleaned up, but crews are still working to get the rest of it. And as Tanya Ott reports there are concerns about a new plan to deal with the ash:

The plan comes from the US Environmental Protection Agency. Clean-up crews would scoop up the ash and put it in the same pit it came from… but the pit’s been reinforced with concrete. What the plan doesn’t call for, though, is a liner to make sure no metals leach into groundwater. Tennessee law and even the EPA’s new proposed coal ash rules require liners.

Craig Zeller is the project manager for the EPA. He says because this pit isn’t new – or expanding – it doesn’t have to comply with the rules. Plus, he says, water testing in the area shows there’s no problem with leaching.

“If, in the future it does show that we need to add a groundwater mediation piece to this, we will!”

Adding a liner after-the-fact could be difficult and expensive. The new clean-up project will take four years and cost 268-million dollars.
