A giant field of plastic debris is floating in the middle of the northern Pacific Ocean. Now researchers are finding more of these garbage patches in other Oceans. Mark Brush has more:

Researchers say there are ocean currents that sort of swirl around like water in a toilet bowl. There called oceanic gyres.

The Algalita Marine Research Foundation was one of the groups that documented the problem in the North Pacific Ocean. This year they sailed to the gyres in the North Atlantic and in the Indian Ocean.

They found miles and miles of plastic fishing line, milk crates, spoons and forks, and bits of plastic bags.

Marcus Eriksen is with the group:

Eriksen: I challenge you to walk into Wal-Mart or a K-Mart and find a product that’s not made from plastic, packaged or labeled with plastic. And we’re finding more and more of this debris being lost onto the ground washing down rivers and streams out to sea.

Eriksen says the plastic is killing some marine animals. Fish, birds, turtles, and whales get tangled up in the mess – or they mistake it for food.

The Environmental Protection Agency
has released its first comprehensive
survey of the nation’s lakes. Samara Freemark tells us what
the study turned up:

More than half the nation’s lakes are in good condition. That’s according to a nationwide survey just released by the EPA. But the agency found that 44% of lakes ranked only fair or poor.

The survey identified two major problems facing lakes. First, many of them are surrounded by development. And that can mean dirt and polluted water running off into the lakes.

And second, many lakes contained high levels of nitrogen and phosphorus, which can lead to harmful algae blooms.

Susan Holdsworth is with the EPA. She says those findings were concerning.

“These stressors are both widespread and pose a significant threat to the condition of our nation’s lakes.”

Holdsworth says the EPA will use the data to assess how well government programs are doing at protecting lakes. The results will also help set future EPA priorities.

Buying a piece of jewelry for
someone is often an emotional
celebration. But some people
are concerned about the damage
caused by mining that gold.
Anna Boiko-Weyrauch takes us from
the jewelry store to the gold mine:

“It is a white gold band, with a star sapphire in the middle.”

In New York City, Sarah Lenigan is showing off her engagement ring. She got married this summer in California. Nowadays some people like her are starting to wonder where the stuff they buy comes from, including their wedding rings.

“You know the idea of the blood diamond, and not just the movie but, you do think about these things when you think about real jewelry. And this is the first time we’ve bought real jewelry, so it was a whole new ball game, I guess.”

It’s hard to say exactly where the gold in Sarah’s ring came from. Gold isn’t like other commodities – it’s almost impossible to track. But more and more, gold like Sarah’s is coming out of Ghana, in West Africa.

(driving sounds)

We’re driving over a dam on the Subri river in Ghana. The country used to be called the Gold Coast and today it’s the second largest producer of gold in Africa. Most of the gold comes out of a number of large surface mines. They’re all owned by companies from abroad.

At this dam, the American gold mining company, Newmont, stores water and waste from its gold mine.

Adusah Yakubu is with me. He’s a member of a local advocacy group. One side of the dam is green forest and clear water. But the other side looks like the surface of the moon.

“It looks like there’s cement in the river. It’s very hard, and it’s very gray. (What is that?) It’s a tailings dam.”

A tailings dam is where mining companies put waste from processing gold. After the precious metal is extracted, you get a mixture of sand and water. It also contains cyanide. Now, the chemical is poisonous, but it’s used all the time in gold mining. And miners work to control it.

But there are also accidents. Some of that waste overflowed this fall at Newmont’s mine, and killed fish downstream. The company says it was a minor event.

For the people who live around Newmont’s mine, the operations have really disrupted their lives. This river used to be the main source of drinking water and food for nearby villages. Kwame Kumah and his wife, Mary Yeboa live by the dam. They say they used to rely on the river for a lot of things.

“There are so many different things we got from the river. You could even get food from it, like fish, crab. But nowadays we can’t get anything from it.”

Now they can’t go near the water because of security guards. Newmont gave the community a well to make up for it. But the villagers say the dam has brought more mosquitoes, and with the mosquitos, disease. Although the company sold them discounted mosquito nets, Mary Yeboa says she gets sick much more than before.

“Right now, my body hurts all over. As I’m talking to you I have a headache, it really hurts. I don’t feel well at all.”

The gold mining company, Newmont declined to comment for this story.

The company sells its gold on the world market. Some people might buy it as investments, others for manufacturing. Or, it could end up as jewelry, like Sarah Lenigan’s engagement ring. That’s actually where most new gold goes, to jewelry.

Soon jewelry consumers, who care about their impact might be able to get some guidance. Certification systems such as the Responsible Jewelry Council are looking at gold, from the mine to the store.

Council CEO, Michael Rae says they are trying to clean up the jewelry business.

“It looks at environmental performance, social performance, labor standards, occupational health and safety, child labor issues and also in business ethics.”

The system won’t guarantee that gold or diamonds are from a specific mine, but it will reveal whether retailers and miners are making an effort to play fair.

Many jewelry and mining companies have signed on to the code. Newmont, the owner of the mine in Ghana we visited, is not a current member.

The US Environmental Protection
Agency has ruled CO2 is a dangerous
pollutant. Lester Graham reports
the finding gives President Obama
something to take to the climate
talks in Copenhagen:

The EPA Administrator, Lisa Jackson, announced the U.S. is moving ahead to eventually restrict greenhouse gases.

“EPA has finalized its endangerment finding on greenhouse gas pollution and is now authorized and obligated to make reasonable efforts to reduce greenhouse pollutants under the Clean Air Act.”

But even with an administrative rule, Jackson says it’s still important that Congress pass a climate change law.

“I stand firm in my belief that legislation is the best way to move our economy forward on clean energy and to address climate pollution.”

The new rule sends a strong message to the climate summit currently going on in Copenhagen that the U.S. is getting serious about the emissions that are causing global warming. And next week, President Obama will go to Copenhagen with something a little more substantive.

Air Pollution at Schools

The US Environmental Protection Agency
is wrapping up a 60-day initiative
looking at toxic air pollution around
schools. They’re looking to gauge the
health effects linked to pollution exposure.
Many of the schools were chosen based
on how close they were to heavy industry.
Gigi Douban reports:

It’s pretty much a given: put a school near heavy industry and an interstate, and those
kids are going to be breathing polluted air. What the EPA didn’t know was just how
polluted it would be. So the agency in August put air samplers outside of 63 schools in
22 states. One of those schools is Lewis Elementary in Birmingham, Alabama.

(sound of calling out names for carpool)

As he does every day, Richard Gooden is waiting in the carpool line to pick up his
granddaughter, who attends pre-K at the school. Not far away, near the basketball
court, there’s an air pollution monitor. Gooden, for one, was glad it was there. Living
up the hill from the American Cast Iron Pipe Company, he’s seen thick layers of dust
settle on his windows.

“I got a little white house with vinyl siding, and you can’t tell there’s vinyl hardly
because of the dirt coming from that pipe shop.”

Gooden has lived in that house for 43 years. His granddaughter spends most days
there, and he worries about her health and his own.

“I had a triple heart bypass a while back. I’m just wondering is that air completely
clean to breathe.”

The EPA plans to have some answers. In Birmingham, the Jefferson County Health
Department is collecting the data on the EPA’s behalf. Corey Masuca is the county’s
senior air pollution control engineer. He says they’re screening for about 100 different
pollutants.

“We looked for them, then, we found them.”

So far, he says, only three of those – benzene, manganese and acrolein – were found
at high levels. Most concerning, acrolein levels were more than 100 times higher than
what the government considers safe. Where does it come from?

“Pretty much any type of combustion source – whether it’s combustion coal, or
fuels from a plant, or fuel from a car. It even emanates from cigarette smoke, so it’s
fairly ubiquitous.”

But ubiquitous doesn’t mean safe. In fact, excess exposure to manganese can cause
brain damage. Acrolein can damage the lungs, and benzene is a carcinogen.

Masuca says the findings aren’t a major cause for concern. But Janice Nolen,
Assistant Vice-President for Policy and Advocacy at the American Lung Association,
disagrees.

“The fact that it’s in lots of places doesn’t mean it is not a big problem. It means
that we have a lot of things that we need to clean up.”

And when it comes to schools, she says, industrial pollution isn’t the whole picture.
Diesel buses drive right up to the school doors every day. Inside schools, poor
ventilation and even things like some glues can lead to health problems.

Yet there are definite links between these air toxins and heavy industry. So Masuca, of
the Jefferson County Health Department, says just knowing what’s out there is a huge
first step. Next they’ll come up with ways to reduce exposure. Things like having kids
stay indoors during recess on days when pollution levels seem to be highest.

Janice Nolen of the American Lung Association hopes monitoring will lead to stricter
controls on nearby industry. And maybe spark even a little bit of self-regulation.

“Letting people know about what’s in the air often raises public awareness and
causes industry to rethink what they’re doing and come up with less toxic ways to
produce their products.”

She says this research can galvanize communities into action. Most of the parents I
spoke with at Lewis Elementary didn’t know a thing about the EPA’s monitoring
program. But perhaps once the EPA gathers long-term data on schools across the
country in the months to come, that will change.

If you learned your town was polluted
with toxic waste, you’d just want to
get it cleaned up. That’s not how things
have worked out with dioxin contamination
in central Michigan. Dioxin’s been a problem
for at least 30 years, but the Dow Chemical
Company, the federal government, and
the state of Michigan are just now hashing
out final cleanup plans. We had Shawn
Allee tour the area to see the
extent of the problem and what’s at stake
for the rest of us:

I wanted to begin my tour with interviews at Dow’s chemical plant in Midland. That’s where dioxin and related compounds were created: the dioxins were by-products of chemical manufacturing.

After a month of calls and emails to Dow, a spokeswoman said the company was interested in talking about the future – not the past. But the past is the reason there’s a problem now.

So, I start my tour a bit downstream.

Michelle Hurd Riddick picks me up near the plant. She’s with The Lone Tree Council, a Michigan environmental group. We follow the Tittabawassee River and the path dioxins took over time.

“This is Freeland Festival Park. Freeland is kind of like a bedroom community of Midland.“

Hurd Riddick says fishing is a huge past time in Michigan – but dioxin’s made it complicated.

Allee: “There’s a fish-advisory sign right there.“

Riddick: “Right. So, they’re telling you to not eat the fish.“

Actually, the signs tell you which fish to avoid, and how much to eat, or not. The US Environmental Protection agency worries dioxin causes cancer and diseases that affect immune, reproductive, and developmental systems.

“Pregnant women shouldn’t eat any, children under a certain age should only eat it once a month.“

Fish advisories cropped up in 1978. That’s after Dow warned Michigan and the federal government about dioxin in the Tittabawassee River. While the plant’s dioxin pollution is well below federal limits, the old dioxins are still around, and they’re not just in the river.

Allee: “Where we coming up here?“

Riddick: “This is Imerman Park, it’s on the Tittabawassee, too, and it’s very frequently flooded.“

Flood waters leave behind contaminated silt. Dioxin’s been found in the soil of yards and in parks like this. One worry is that kids would get exposed by getting dirt in their mouths.

Riddick: “Those are the hand washing sinks. They put the sinks there to use the hand-washing sink to wash their hands as a way to mitigate their exposure.“

Allee: “There’s the sign – contamination advisory: avoid contact with soil and river sediment. Please use soap and water to wash off soil and sediment.“

Other parks and some yards had soil scraped and removed. Dow cleaned up several dioxin hot-spots in recent years. Michigan and the US EPA want more of a top-to-bottom effort. That might include a sweep of fifty miles of river and part of the Great Lakes.

Riddick: “This is the Saginaw Bay of Lake Huron. As a child, I came up here a lot. I’m sure someplace I have a picture of me near these trees.“

Riddick’s middle-aged now. The dioxin was in rivers and Lake Huron before she was born. No one knew that far back. But residents did learn about the problem thirty years ago. Today Dow, the US EPA and Michigan are still debating a final solution.

“We’ve had many, many starts. If I had a nickel for every time I heard someone say this is how we’re going to achieve this cleanup, I’d be a wealthy woman.“

Hurd Riddick says the whole country should care about how this plays out.

Riddick: “People need to care about how this process because could play out in your community.“

Allee: “Maybe not dioxin but something else?“

Riddick: “You want to know that that the people your tax dollars are paying to protect you are the ones calling the shots.“

A final dioxin-clean up could take more than ten years. Michelle Hurd Riddick says she can wait that long – if it’s done right.

But she says it wouldn’t hurt if the clean-up got started now.

Milk and Manure in the Dairy State

But, in many places around the country,
it’s also meant a lot of pollution.
Mark Brush visited a place where they
say big dairies are doing it right:

(sound of a farm)

Tom Crave and his brothers run this dairy in central Wisconsin. Crave says, when they first started out, he and his brothers were single, they had 80 cows and a used car.

Now, they have around a 1,000 cows and families to look after. He says they had to get big to survive.

“It takes a lot of money to live. That’s what’s… that’s what’s driven this here. It’s just basic economics.”

It’s a theme farmers all over the country have been hearing for decades. Get big or get out. You can’t make money unless you grow.

The Crave Brothers milk their 1,000 cows three times a day. They use automated milking machines. And they turn that milk into cheese that they make across the street in their cheese factory.

But milk is not the only thing cows produce. These farms deal with millions of gallons of liquid manure.

Most farms store the manure in lagoons – basically huge pits of waste contained by earthen berms. Then, when these lagoons fill up, they spray or inject the liquid manure onto the ground as fertilizer for crops. It’s also the main way they have to get rid of all that waste.

Sometimes these big dairy farms have problems. Liquid manure runs off the crop land, contaminating rivers and lakes. And, in some cases, the earthen berms holding back the manure has leaked or given way, releasing a wave of manure, causing huge fish kills or polluting well water.

But regulators here say the Crave Brothers have been doing a good job taking care of their manure. As have most of the other big dairy farms in Wisconsin. That’s in part because these farms actively regulated in the state.

Gordon Stevenson is the Chief Runoff Manager for the Wisconsin Department of Natural Resources.

“It is not coming from these largest farms for the most part. The manure management on our 30,000 other smaller farms can be a good bit worse, and those people are not regulated.”

Dairy farms that have fewer than 700 milking cows usually are not regulated under the Clean Water Act until there’s a major problem. And some farms stay under 700 cows to avoid regulations.

“When we encounter environmental problems associated with one of these smaller farms, they can be offered cost share assistance. They’re largely voluntary programs.”

If Stevenson finds a smaller farm that’s polluting, he can offer them some state money to fix the problem. But, beyond that, he says there’s not much his office can do. As a result, some smaller farms pollute.

Jamie Saul is with Midwest Environmental Advocates. His group has represented people who were sickened from well water contaminated by manure. Saul says, there have been some problems with bigger farms in the state, but he admits the bigger challenge is how to control pollution coming from smaller, unregulated farms.

He says just offering them money to clean up is not good enough.

“We are the habit now of paying, and I think it’s pretty unique to the agricultural industry, that we pay them to reduce their pollution. Most other industries we don’t do that. We expect whatever industry it is to come into compliance with whatever standards are needed to protect the environment and public health.”

Saul says all states needs better policies to keep small farms from polluting. He says the regulations have to have that magic mix of stopping water pollution without putting too much burden on small farmers.


While Wisconsin regulators seem to be keeping an eye on their bigger farms, environmental activists say that’s not the case in other states. They say Clean Water Act rules are often not enforced against livestock farms – big or small – and that puts the environment and people’s health at risk.

American gasoline refineries are
expanding to process a dirtier kind
of oil. Shawn Allee reports
one company’s plans hit a snag:

The BP fuel refinery in Northwest Indiana wants to process more Canadian tar sands oil.
Processing tar sands crude creates more air pollution than normal. The federal
government wants more air pollution figures from BP before signing off on an air
permit.

Groups like the Natural Resources Defense Council pressed the government to step in.
The NRDC’s Ann Alexander is glad BP’s tar sands project is getting scrutiny.

“If tar sands are going to be developed, we think it’s it’s critical they be developed in
a way that complies with the Clean Air Act, because the Clean Air Act is there to
make sure it’s not the community that pays for development of tar sands through
increased pollution and the health problems that result, but that it’s BP who pays
those costs.”

BP’s tar sands oil project in Indiana is just one of several going on in the Midwest.

The Environmental Protection Agency
is holding up nearly 80 permit
applications for coal mining projects
because of concerns about about water
quality. Tamara Keith
reports this is creating a different
kind of concern in Appalachian coal
country:

The applications involve mountain top removal coal mining. Explosives are used to get at coal that’s close to the surface.

In the past, the mining companies have been allowed to fill in valleys with the leftover rock and dirt. But the EPA is concerned that streams are getting buried and polluted so the agency is now giving that practice a serious second look.

Carol Raulston is with the National Mining Association. She says holding up those permits have people in the mining towns of Ohio, West Virginia, Kentucky and Tennessee worried about losing their jobs.

“You really can’t operate these mines and employ people at them unless you’re able to construct the fills and in many of these communities they are the sole employer.”

An EPA spokesperson says protecting drinking water and coal mining jobs are both important. The agency says both can be done.

The federal government and a major
chemical company have reached an
initial agreement about cleaning
up one of the nation’s largest dioxin
pollution sites. But, Shawn Allee reports, the public will
have to wait a bit to examine the
fine print:

Central Michigan has a dubious distinction: The Environmental Protection Agency
claims that a flood plain there has some of the highest dioxin levels ever found in soil.

That dioxin came from a Dow chemical plant decades ago. The EPA and Dow just
concluded negotiations over a clean-up deal.

Wendy Carney is with the EPA’s regional Superfund cleanup office. Carney says the
deal is not done, though.

“This agreement doesn’t actually contain any cleanup options. It also doesn’t
address any cleanup levels for the site. That would be a part of things we would talk
about with the public in a public forum to get their feedback on those issues.”

Carney says the EPA could unveil its agreement with Dow in two weeks.

The EPA suspects dioxins cause cancer and other health problems.
