A recent study from the Louisiana Universities Marine Consortium shows the dead zone in the Gulf of Mexico is getting bigger. The Great Lakes Radio Consortium’s Jonathan Ahl reports that pollution from the Midwest may be to blame:
The 85-hundred square mile area suffers from hypoxia. That’s when the levels of dissolved oxygen fall low enough to kill off most fish and plants. Many scientists believe nitrogen coming from Midwest farms and wastewater plants that travel down the Mississippi River are responsible. Forrest Peterson is a spokesperson with the Minnesota Pollution Control Agency. He says Midwestern states are aware of the problem, and are trying to fix it:
“Things like providing buffer strips and projects to retain some of the water’s nutrient management, things like that. So there are a whole array of things that can be done and that are being done, it just takes some time to see that effect.”
Peterson says the federal government has set the goal to reduce the zone to two thousand square miles and reduce nitrogen levels in the Mississippi River by 30 percent by 2015. For the Great Lakes Radio Consortium, I’m Jonathan Ahl.
Principles of sustainable design, or “green building” have been around for years. These are designs that, among other things, reduce energy use and create more comfortable working environments. Yet they are often dismissed as costly, impractical, and experimental. But green design has come a long way in recent years. The construction cost of an environmentally-friendly office building today is comparable with the cost of more traditional methods, and the maintenance costs are often much lower. Architects and builders across Pennsylvania have learned that, and the result has been a major shift in how buildings are constructed. And the lessons learned there could eventually make their way across the entire Great Lakes region. The Great Lakes Radio Consortium’s Brad Linder reports:

Principles of sustainable design, or “green building” have been around for years. These are designs that, among other things, reduce energy use and create more comfortable working environments. Yet they are often dismissed as costly, impractical, and experimental. But green design has come a long way in recent years. The construction cost of an environmentally friendly office building today is comparable with the cost of more traditional methods, and the maintenance costs are often much lower. Architects and builders across Pennsylvania have learned that, and the result has been a major shift in how buildings are constructed. And the lessons learned there could eventually make their way across the entire Great Lakes region. The Great Lakes Radio Consortium’s Brad Linder reports:
The Heinz National Wildlife Refuge at Tinicum Marsh lies just around the corner from the Philadelphia International Airport. The refuge is also home to the Cusano Environmental Education Center, celebrating its first anniversary as what many consider to be the city’s greenest building.
The Center’s heating and cooling relies on a geothermal system. About five hundred feet below the Cusano Center, the temperature remains near 50 degrees all year round. Deep wells reach into the ground to borrow heat in the winter, and cool air in the summer.

The Center also makes use of a “marsh machine,” to clean and recycle wastewater. Refuge Manager Dick Nugent says the machine uses natural processes to filter water through a “constructed wetland” of PVC pipes, gravel, and marsh plants. Nugent says the city water department delivers drinking water, but the marsh machine has a more important use.
“We wanted this here as an environmental education tool. It isn’t as if we needed it for the functionality of this building. The message to take home is that marshes serve a very important function.”
Cyrus Baym is a volunteer coordinator at the Cusano Center. He says people come expecting to learn about nature, but wind up getting something special out of the building.
“The people that are coming in, they see this fabulous building, a lot of space, a lot of glass, and then when you start explaining along with the exhibits the sustainable design features, the use of recycled materials, passive solar windows their eyes get even bigger. They get more excited and want to implement it in their own house.”
Refuge Manager Dick Nugent says there was some additional cost to innovations like the geothermal system and the southern wall of the building, which is made mostly of glass windows. But in the long run, many of those additions will wind up saving money on electricity and heating. And the overall goal isn’t to be frugal, but to teach.
On the other side of the state, another approach toward sustainable design is taking hold.
Pittsburgh is currently home to one-quarter of the nation’s buildings that have been certified as green by the U.S. Green Building Council. The non-profit national industry group represents design, construction, and environmental interests. The council also administers the Leadership in Energy and Environmental Design, or LEED, rating system, which judges the overall environmental performance of buildings.
Unlike the Cusano Center in Philadelphia, many of Pittsburgh’s green buildings weren’t designed to be educational tools. The PNC Firstside Center in Downtown Pittsburgh provides workspace for 1800 employees in the bank’s technology and processing divisions.
Elmer Burger was one of the principle architects for the building. He says designing the largest LEED certified building in the country made sense for the project. The large floor space improved communication within business departments, and also allowed for extensive use of natural light.
“With a large floor plate, we had an opportunity to make the ceilings higher and bring daylight further into the building. So you can be as far as 125 feet away from the outside wall and still have daylight in a view.”
Burger says the building’s large windows give employees a view of the Monongahela River, and also save money by reducing the need for artificial light.
Rebecca Flora is director of Pittsburgh’s Green Building Alliance, a non-profit group working to encourage and facilitate environmentally friendly design in the city. She says some non-profit groups are interested in green buildings for ideological reasons, but also wind up getting long-term economic benefits.
“The life cycle value of doing a green building is actually quite significant in some cases. I know with Conservation Consultants, their building actually uses 60% less energy than a traditional building, which can have huge implications in terms of the small operating budgets that many non-profits have to work with.”
Flora says saving money is one of the main factors in getting major institutions like PNC to build green
“The myth that is out there is that green buildings cost more, and that’s one that we’re constantly trying to educate people around in that you get what you pay for. We’re trying to educate people around the fact that green building also adds value, and how do we equate that value with increased bottom line is a real key issue for most people.”
Flora says it’s important to convince clients, and not just architects of the benefits of green design. She says if the demand for LEED certified buildings increases, sustainable design techniques will become more common.
A number of other commercial and non-profit institutions in the city have also chosen green design. Both the Alcoa Corporate Center, and the Greater Pittsburgh Community Food Bank are green buildings. And the new David L. Lawrence Convention Center is the first convention center in the country to earn LEED certification
With so many high profile green projects, sustainable design is starting to look like common sense to many architects and their clients. Elmer Burger says the success of the PNC Firstside Center has led the company to adopt a new policy. All of their new corporate buildings will be designed to meet LEED requirements.

The largest meatpacker in the world has agreed to pay millions of dollars in penalties because of pollution at its plants. The Great Lakes Radio Consortium’s Lester Graham reports.
Iowa Beef Packers, known as IBP Incorporated, has agreed to pay more than four million dollars in penalties and make ten million dollars in pollution prevention improvements at several of its plants. That agreement settles a lawsuit filed by the U.S. Environmental Protection Agency. Among a number of violations at several plants, the EPA had charged that IBP was releasing large quantities of ammonia into the Missouri River and one of its plants emitted 19 times the maximum amount of the pollutant, hydrogen sulfide, from its smokestacks. Besides paying the penalties, IBP will upgrade its wastewater treatment facilities and install required air pollution control equipment. In a release, IBP states that it doesn’t “agree with the nature and extend to the claims made in the federal government’s lawsuit.” but it’s glad to put the matter behind it. IBP was recently acquired by Tyson Foods. Government officials say with the settlement, they hope IBP will now be a better neighbor. For the Great Lakes Radio Consortium, this is Lester Graham.
Lake Michigan had a record number of beach closings this year. The Great Lakes Radio Consortium’s Jonathan Ahl has more:

Lake Michigan had a record number of beach closings last year. The Great Lakes Radio Consortium’s Jonathan Ahl reports.
The Lake Michigan Federation is reporting almost six hundred beach closings on Lake Michigan in 2001. That’s up from just over four hundred last year. Federation director Cameron Davis says most of the closings are due to wastewater carrying bacteria to the lakes when treatment plants are at capacity. He says the solution is to cut back on development near the lakes:
“We need to try to limit the amount of pavement that’s being laid down all across the region, so that rainwater naturally filters through the ground rather than getting shuttled off into a sewage treatment plant.”
Davis says the number of beach closings on Lake Michigan should actually be higher than his report shows. He says Michigan does a poor job testing for bacteria near beaches, and says Wisconsin’s numbers are excluding Sheboygan County where there have been problems in the past. For the Great Lakes Radio Consortium, I’m Jonathan Ahl.
Lake Michigan beaches were closed more often this summer than ever before. As the Great Lakes Radio Consortium’s Jonathan Ahl reports, beach closings can translate into significant economic loss:

Lake Michigan beaches were closed more often this summer than ever before. The Great Lakes Radio Consortium’s Jonathan Ahl reports.
A report from the Lake Michigan Federation shows an all-time high of 600 beach closings in 2001. High levels of bacteria found in the water caused most of the closings. Federation director Cameron Davis says in addition to the environmental problems, the closings have an economic impact on the region:
“Take a look at a place like Chicago that gets 60 million visitors a year to the lakefront. And you get a beach closing Labor Day weekend or a fourth of July weekend. You’re looking at millions of people, some from around the world, that can’t visit the beaches here.”
Davis says the bacteria is getting into the water when heavy rains force wastewater and sewage carrying human and animal waste past treatment plants and into the lake. The Lake Michigan Federation is setting up a center to help citizens and community groups solve bacteria problems at beaches. For the Great Lakes Radio Consortium, I’m Jonathan Ahl.
Around the country, more and more people are getting interested in earth-friendly solutions to everyday problems. Sometimes they hit on a way of solving two problems at once. The Great Lakes Radio Consortium’s Stephanie Hemphill reports on a project that combines household wastewater treatment with a solar greenhouse.
Millions of American women rely on birth control pills to prevent pregnancy. Millions more depend on replacement hormones to prevent symptoms of menopause like hot flashes and osteoporosis. Both medications contain a synthetic version of the female hormone estrogen. And now, researchers at the University of Mississippi found that some of that estrogen ends up in wastewater. The Great Lakes Radio Consortium’s Steve Frenkel has more on the potential effects:
