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.”

Getting Chemicals Out of Drinking Water

Some chemicals are getting into drinking water, and it’s not so easy to get them out. The Environmental Protection Agency says it’s working on the problem. Lester Graham reports on the agency’s plans:

Transcript

The Environmental Protection Agency is outlining a plan to reduce the amount of chemicals getting into drinking water. Lester Graham reports.

The EPA’s administrator, Lisa Jackson told members of the Association of Metropolitan Water Agencies about the new plan. She said it would work to improve technology to clean up water, get tougher with polluters, coordinate efforts with the states, and deal with contaminating chemicals in groups rather than individual chemicals.

James McDaniels is President of the water agencies group. He says that last idea might speed up the process of getting some contaminants out of water.

“Focusing too much on one contaminant and not looking at it holistically and not really seeing what the other ones are. We all have limited reso urces and as utility managers, looking at these things more holistically makes a lot of sense to us.”

Pesticides, pharmaceuticals, and other chemicals make cleaning up drinking water a real challenge for the water agencies.

Congress might make our federal
chemical laws tougher. Rebecca
Williams has more:

There are 80,000 chemicals on the market. But the Environmental Protection Agency has only tested 200 of them for safety to humans – and banned only 5 of the toxic chemicals.

Senator Frank Lautenberg is a Democrat from New Jersey. During a recent hearing, he said the EPA is doing what it can. But its power is limited by the nation’s outdated chemical laws.

“They cannot protect our children with one hand tied behind their back. That’s why I’ll soon introduce a bill that will overhaul our nation’s chemical laws.”

The bill will likely require companies to prove a chemical is safe before manufacturing it or using it. Right now, it’s up to the government to prove a chemical is harming people or the environment before it’s banned.

Some Conservatives in Congress are opposed to this idea. They say this kind of bill would kill industry innovation.

Drilling for Radioactive Gas?

There are proposals to drill for oil
and gas very close to the site of a
nuclear explosion. The device was
exploded underground in western Colorado
40 years ago this month. Natural gas
from wells near the site could be
distributed throughout the U.S. Some
experts are concerned the natural gas
could be radioactive. Conrad Wilson
reports regulators could allow drilling
closer to the blast site in the next
couple of years:

On September 10, 1969 the Atomic Energy Commission detonated a 40-kiloton
nuclear bomb a mile and a half under ground. It was called Project Rulison. The
bomb was three times the size of the one dropped on Hiroshima.

The idea was to find peaceful uses for nuclear weapons. The federal government
hoped that nukes could be used to free up pockets of gas trapped below.

(sound of video)

The nuke did free up gas.

The government tested the gas by flaring it – burning it in the open – over the next
year. They discovered the natural gas was radioactive.

Marian Wells is a long time resident of Rulison. Her parent’s home was close to
the detonation site and the gas flares. Both of her parents died of cancer. So did
many of her neighbors.

She spoke before the Colorado Oil and Gas Conservation Commission.

“My parents were given no notice that you were flaring contaminated gas. And
yet both my parents died of cancer. Cancer is prevalent in this area. And yes, no
one has studied those cause and effect. You don’t really care about us.”

There’s been no government studies connecting cancer and the Rulison blast,
but the community remains fearful and suspicious.

Gas drilling is allowed as close as three miles of the blast site. That natural gas
is piped around the country.

Now some companies say they want to drill for natural gas within a half mile of
ground zero.

The Department of Energy maintains that, for the most part, the gas near the
blast site is safe, but there’s some uncertainly.

Jack Craig heads up the Rulison site for the Department of Energy. Craig says
drilling closer to the nuclear blast site should move forward slowly.

“What we’re saying is do it in a sequential manor. So that you come in slowly
testing the wells as you go in for contaminants – specifically tritium – and, if you
don’t find anything, move in closer.”

Tritium is a radioactive substance produced by the blast. Breathing tritium can
cause cancer.

Chris Canfield works on environmental protection for the state oil and gas
commission. He heads up an annual audit on the Rulison site.

Canfield: “Simply put, everything that’s coming out of the ground is being
sampled, being analyzed.”

Wilson: “If someone were to come to you and say they want to drill within the
half mile of the Rulison blast site, would you say that’s safe?”

Canfield: “I wouldn’t really know at this time.”

Canfield says that the state would require a special hearing before it would
approve any drilling permits any closer.

Oil and gas commissioner Jim Martin says there are still too many unanswered
questions to allow drilling that close to the blast site.

“There are significant information gaps and that makes is very difficult to really
understand the risks either to the workers or to the public who live within some
distance of the drill site.”

Martin says he understands why people are skeptical. He says the United States
has made a lot of mistakes with radioactive materials. Navajo uranium miners
got cancer because of radio exposure. People downwind of above ground
detonations suffered. Martin says skepticism is warranted.

“So it’s not unreasonable to ask some pretty tough questions of the federal
government before we go further into that half mile perimeter and produce more
gas.”

Gas that could be burned to heat homes across the U.S.

The federal government’s Energy
Star program is supposed to highlight
products that save you energy and money.
Rebecca Williams reports some independent
testers found Energy Star might be falling
a bit short:

The magazine Consumer Reports tests all kinds of products to see how they
stack up. They were testing refrigerators when they stumbled on something
odd.

Steven Saltzman is a Deputy Editor with Consumer Reports. He says the
Energy Star program relies on government standards that are outdated in some
cases. For example, one standard is to test a refrigerator’s energy use with the
icemaker off.

“But we found that when you turn the icemaker on – the refrigerator actually
used twice as much energy as it would with the icemaker off.”

Saltzman is not saying you can’t trust the Energy Star label. But he says the
tests need updating. And there’s a dark Energy Star secret, manufacturers get
to do their own testing in most cases – so there’s not a whole lot of third party
checking going on.

Pheromone to Help Control Lamprey?

Transcript

Researchers say they’ve discovered a migration pheromone in sea lamprey. It’s a natural attractant that could boost efforts to control the invasive parasite. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:


Each lamprey can kill forty pounds of fish in its lifetime. Managers use a pesticide to keep the lamprey numbers down, but it’s expensive, and sometimes it kills other fish.


University of Minnesota biologist Peter Sorensen says he’s isolated a chemical signal put out by lamprey larvae. The larvae live in streams, and the signal apparently tells adult lamprey that the stream is a good place to lay eggs.


“We’ve got a cue that’s very powerful, very safe, we don’t need very much of it, and it can control the distribution of the lamprey in a way that other things can’t.”


Sorensen says the pheromone can be used to corral lamprey into areas where they can be trapped or treated with pesticide. The pheromone is being tested in a river in Michigan.

Prospecting for Wind

  • The wind is up, and so is interest in wind power development. (Photo by Lester Graham)

Wind power is a small, but fast-growing segment
of the U.S. energy market. Right now, energy companies are scouring rural America for the best spots to put up wind turbines. But wind is not enough – these companies need land, too. The Great Lakes Radio Consortium’s Shawn Allee looks at one wind developer’s search for its next wind farm:

Transcript

Wind power is a small, but fast-growing segment of the U.S. energy market. Right now, energy companies are scouring rural America for the best spots to put up wind turbines, but wind is not enough – these companies need land, too. The Great Lakes Radio Consortium’s Shawn Allee looks at one wind developer’s search for its next wind farm.


The search for wind power could turn into a modern-day gold rush. Wind’s becoming a profitable way to meet growing demand for clean energy, but wind power companies face an obstacle: they can’t just find a windy spot and throw up some wind turbines.


They’ve got to sign a contract with a landowner, usually a farmer, who’s willing to rent out some breezy land. Mike Donahue is Vice President of Midwest Wind Power. His main job: find windy land and the farmers who own it. Donahue says the job’s changed recently.


“The biggest difference is the level of knowledge and sophistication that local elected officials and landowners have gotten regarding windpower. I mean, when we first started, they were like, ‘Wind what? Wind turbine? What’s that?’ They didn’t even know what a wind turbine looked like, let alone whether they wanted one in their field or not.”


For their part, savvy farmers aren’t waiting around for companies to call them. They’re taking the initiative. David Coffey farms hundreds of acres in Illinois. A few months back, he did a little investigating.


“First of all, I just had got the information from the Farm Bureau Magazine and what was going on in other areas. And I just got it in my mind, I thought, ‘Well, I’ve got a ridge here, what’s it worth?'”


So Coffey got equipment from a university and tested the wind along his ridge. The initial results were promising, and the university posted the data online. Donahue’s company noticed the results, and gave David Coffey a call.


Which leads us to today. Coffey’s agreed to give the company a tour of the area. After some quick introductions, Donahue, his partner Tim Polz, and I, squeeze into Coffey’s white pickup.


(Sound of door shutting)


Coffey drives us along a maze of gravel-lined back roads and soy bean fields. Soon, we see the ridge that brought Donahue’s company here. It’s not that spectacular, really. It’s just a big, rolling hill, but it spreads to the horizon.


DONAHUE: “Just eyeballing this, it looks like this ridge runs how many miles, would you say, from east to west?”


COFFEY: “Well, I would say it’s going to be close to… I’d say eight to ten.”


DONAHUE: “And then it’s roughly a mile across it?”


COFFEY: “Yeah, or a little better, if you’re gonna stay right on top of it, I’d say.”


Midwest Wind Power wants a large site like this, because it’s hard to turn a profit on smaller ones. Several farmers own bits of this ridge, so Donahue might have to deal with all of them, and that could be a headache.


David Coffey says some locals are worried about helping out. Landowners who build support for the project might not have enough wind on their own farms to qualify for a turbine and a rental
contract. Donahue says there’s a way to smooth that over. If someone’s been helpful but is left out…


“We actually do offer a kind of good neighbor compensation package to them as well.”


Of course, maybe other companies noticed David Coffey’s wind data, too. Donahue’s assistant, Tim Polz, broaches the subject.


“Have you guys had any of the other developers give you any type of financial offers?”


Coffey says yes, but doesn’t elaborate. Donahue makes his pitch. He says his company offers more than good rent, it offers other benefits attractive to farmers.


“Along those lines, we grant a great deal of flexibility to the landowners to have input into turbine locations, access road locations, cabling routes.”


Even with this flexibility, though, money counts. The company will pay farmers about seven thousand dollars each year for every turbine on their property. That’s a lot for an Illinois farmer. On average, they make only thirty thousand dollars in farm income each year.


Soon the conversation shifts away from money. Donahue asks whether Coffey’s neighbors are mostly farmers.


“If you’re in an area that has a number of non-farming residential homes, maybe built in wood lots, or people who want to live in the country, they’re less accepting of having wind turbines developed in view of their homes.”


Coffey assures him nearly everyone’s a farmer out here. And with that, he ends the tour.


“Well, what do you think of the area?”


Donahue says the company needs to run more wind tests along the ridge, but overall…


“The first impressions are very favorable as to the site and its potential. We’re looking forward to meeting with your other landowners and then ultimately, meeting some elected officials as well.”


It’s not clear what will come of today’s meeting. Maybe another company will land a contract, or perhaps there’ll never be turbines here, but the chances for success improve with each encounter.

Moving Away From Tail Pipe Tests

There’s a new trend in how states with air quality problems carry out
vehicle emissions testing. Some say it will allow cars that give off
harmful pollutants to stay on the road. The Great Lake’s Radio Consortium’s

Transcript

There’s a new trend in how states with air quality problems carry out vehicle emissions testing. Some say it will allow cars that give off harmful pollutants to stay on the road. The Great Lake’s Radio Consortium’s Amanda Vinicky reports:


States that are required to test emissions usually test a car’s tailpipe. Illinois is switching to “onboard diagnostics.” That means the vehicle’s onboard computer gives testers all the information they need.


But older cars don’t have computers, so the state’s exempting all cars made before 1996 from testing. Brian Urbaszewski is with the American Lung Association.


“When you stop testing them, people aren’t even going to know their cars are polluting. Or, even if they know, they’re going to be less likely to fix it because there’s no penalty involved.”


The Lung Association says the Illinois Environmental Protection Agency’s own documents show that air quality will get worse after the 2007 change.


State and federal EPA officials admit that’s true, but they say fewer of those cars will be on the road each year. They say computer testing is better because it detects problems before they happen and it’s cheaper.

Kids Get a Hands-On Outdoor Education

  • Instead of a traditional classroom, the students of Goodwillie Environmental School are learning outside. (Photo by Michel Collot)

Most 5th and 6th graders right now are enjoying outdoor activities during their summer vacation. But at one public school, the outdoors is part of the curriculum, year round. The school aims to turn kids who love the outdoors into lifelong stewards of the earth. The Great Lakes Radio Consortium’s Tracy Samilton reports:

Most fifth and sixth graders right now are enjoying outdoor activities
during their summer vacation, but at one public school, the outdoors is
part of the curriculum, year-round. The school aims to turn kids who love
the outdoors into lifelong stewards of the earth. The Great Lakes Radio Consortium’s Tracy Samilton
reports.


(Sound of sawing wood)


Sawing logs is hard work, especially for fifth graders like Amelia, Leoni,
and Taylor. The results can be seen in this rustic, but sturdy log cabin
overlooking the Goodwillie Environmental School. The cabin was built almost
entirely by the fifth grade class in half hour shifts, because the work is
so demanding.


“We worked on the chinking, the floor inside here – I did that
chinking! And then we worked on the floor inside here – and
when we get enough bricks, that’s what the fireplace is going to look like.”


The students get most of their instruction in science, math, history, and
other subjects as they hike through the woods or work on an outdoor project
like the cabin. Of course, they spend some of their time in the classrooms
in the southwest Michigan school. But today, volunteer George Stegmeyer is
building a kiln, where he will fire raw bricks for the cabin’s fireplace. The
bricks were made by the students with mud they dug from the grounds.
Stegmeyer explains how the hot air will move through the kiln and then blast
through the chimney.


“Just like firing pottery, it reconfigures the molecules so that they are no longer water-soluble.”


The students call Stegmeyer “grandpa,” an example of the extended family
atmosphere of the school. Only about fifty children are selected each year:
the ones who show a passion for the outdoors. Parent Peter Chan says it’s
not for every kid, but he wishes all school districts had an option like
this.


“I spent from sunup to sundown, most of the time, I can remember playing outdoors, if not exploring

the fields, the farmer orchard, or the woods by my house. Unfortunately
today, children don’t have that experience.”


Chan went to a similar school when he was young. He’s now a meteorologist.
He’s enthusiastic about his son having the same opportunity. Some of the
parents might worry that their child could fall behind in traditional
coursework here. But fifth-grade teacher Rick Gillett says there’s nothing
to fear. Students consistently score one hundred on the state’s annual standardized
test, all without “teaching to the test.”


“For instance, in the science test, when you get into the physics, in inclined planes and pulleys,

when you’ve actually used them in building the log cabin, it makes sense. You really understand how

the physics work.”


Gillett says he doesn’t expect every student in the outdoor school to become
a biologist or forest ranger, but he does expect the school to make a
lasting difference. He says some of his former students have come back
to see him when they’ve reached college age. He says that’s when it really
seems to sink in how much they learned here.


“I really do… I think that once it’s in your heart you’re never going to get it out of
there.”


That already seems to be the case with most of the students. Fifth-graders
Spencer and Evan can’t wait until sixth grade, when they’ll have a chance to
tackle a project in the Native American village that’s tucked into the woods
below the log cabin. They show off the two buildings that previous sixth
graders built: an Ojibwa smokehouse and a winterhouse.


“This is the inner bark of basswood it basically ties whole thing together, holds it up. These go

down about five feet into the ground, these go down about ten feet into the ground, so as you can

see it’s very, very sturdy.”


This fall, a brand new group of fifth graders will arrive at Goodwillie
Environmental School. They’ll take up where the last class left off and
build the fireplace for the cabin. Along the way, they will also pick up
the knowledge, experience, and passion for the outdoors that will help them
be lifelong stewards of the earth in years to come.

The testing is just getting underway on people who have been drinking water contaminated by C8.
It’s being done as part of the settlement of a class-action lawsuit against the company.


Residents of nearby water districts accuse the company of witholding information about the health threats posed by C8. Project coordinator Art Maher says medical histories, personal information and blood samples will be collected from the test subjects, who will be paid for their participation.


“That information then will be fed into a database that ultimately will be passed on to the next step of the settlement agreement, which would be the science panel who would interpret the data.”


If the experts determine there is a link between C8 and any disease, DuPont will be required to spend as much as 235 million dollars on a medical monitoring program for additional testing.
