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.

Growing a City in a Greener Way

For many small town mayors, growth is all good. After all, more houses means more tax revenue, more retail, more jobs. One Alabama mayor agrees, but he also recognizes green space is an amenity worth keeping. And for that, the timing couldn’t be better. Gigi Douban reports:

For many small town mayors, growth is all good. After all, more houses means more tax revenue, more retail, more jobs. One Alabama mayor agrees, but he also recognizes green space is an amenity worth keeping. And for that, the timing couldn’t be better. Gigi Douban reports:

Here at the grand opening of a subdivision in Trussville, Alabama, a few dozen families gather outside the sales office for the usual ribbon cutting with giant scissors.

(sound of applause and cheers)

Soon, everyone heads down to the Cahaba River. The river literally will be in the backyard of these houses once they’re built. On the river, they’re having a rubber duck race.

(announcement of duck race)

It’s gimmicky, but these days developers will do just about anything to attract potential buyers.

Another developer had approached Trussville about building homes along the Cahaba River, but then the housing market took a nose dive. The developer wanted out.

Trussville Mayor Gene Melton says the city would have been crazy not to buy the land.

“This property was probably going to sell for $35,000 or $40,000 an acre. We got to the point where we were able to acquire this for $4,500 an acre.”

The city could have turned it into an industrial park or zoned it for retail. But instead, they’ll turn it into a greenway. It’ll connect to nearby parks with the river as the centerpiece.

Now, the mayor of Trussville is not a staunch environmentalist, by any measure. He tools around the city in a gas guzzling SUV. He’s pro-development. But, he says, the same way a city needs development, it needs greenspace, too.

“Have you ever flown in to a big city like Atlanta or Los Angeles and for miles and miles all you see is rooftops? Well that’s how not to build a city.”

The Cahaba River watershed stretches through Alabama’s most populous county. Recently, heavy development along the Cahaba has polluted the water. It’s endangered habitats not just here, but downstream. Trussville is very near the headwaters, so what happens there affects the entire river.

Randall Haddock is thrilled about the new greenspace. He’ a field director with the Cahaba River Society, a conservation group. Haddock says the Cahaba River is among the most biologically diverse in the country.

“It turns out that Alabama has more fish species, more snails, more crayfish, more turtles, freshwater snails more than any other state in the US. So when it comes to things that live in rivers, we’re at the top of the list by a long way.”

(sound of people walking near river)

Haddock says all along the Cahaba, he’s seen plenty of examples of how not to build near the river.

He says this greenspace is an example of how easy it is to minimize impact. Keeping grass on the ground not only means a cleaner river, but it might help reduce flooding.

“When you make so many hard surfaces, the water runs off real fast and gets into the river real quick. And you’ve increased the volume of water and the only response that a river can make is to get bigger.”

The bank erodes, the water is polluted and soon, you start to see species diminish.

(sound of high school students)

David Dobbs is the city’s high school environmental science teacher. He takes his students out behind the school to check on the river. The result: a clean bill of health.

“All the little bugs, they end up being food for the fish, and the more they are of the good ones that are here, that means there’s more food for the fish, so therefore there’s more fish, it’s a very healthy part of the river.”

Trussville, like many small towns, still says without growth, there’d be no city. But now they know, that growth has to protect one of its top amenities – the river.
