You might not expect much good
environmental news to come from
sewage plants, but, believe it or
not, there is some on occasion.
And in one case, that good news
even involves thriving salmon.
Shawn Allee has the story:

Sewage plants are often out of sight, out of mind, and people usually like it that way. But people who work at the water treatment plant in East Chicago, Indiana, want everyone to know about an ecological come-back story there.

I’m game. So I meet the plant director Peter Baranyai.

Allee: “You’ve got this strange mix of some really striking natural areas, rivers and streams, but then everything’s kind of dotted by industry as well, and has been for a long time. What kind of industries are we talking about in this region?”

Baranyai: “Basic steel mills, oil refineries, chemical industries also.”

Allee: “So, when they’re talking ‘heavy industry’, they really mean it here?”

Baranyai: “Yes.”

Allee: “What are we looking at here?”

Baranyai: “We’re trying to look at our discharge channel. That’s the effluent from our treatment plant. This pipe here’s a 60-inch pipe.”

Allee: “You can see the water moving out of it pretty quickly.”

The treated wast water is from nearby homes and factories. And when it leaves the pipe, you’d swear it’s a natural stream. Apparently, it’s fooled plenty of critters, including Chinook salmon.

Each Fall, salmon swim from Lake Michigan, past shipping canals, steel mills and chemical factories – just to spawn in the treated waste water.

Baranyai: “They’re not being too cooperative today because I don’t see too much.”

The salmon spawned earlier than normal this year, so, I only find dead salmon on the banks.

Baranyai: “This was a, oh, almost 4-foot chinook salmon.”

Allee: “Or the evidence of it.”

Baranyai: “And he died.”

Allee: “Again, they’re kind of programmed to die after they spawn.”

Baranyai: “Yeah, he died on the rocks here.”

The government introduced Chinook salmon to Lake Michigan decades ago, but for a long time, salmon wouldn’t spawn here, and birds and nearly everything else shied away, too.

Baranyai says one problem was that they used to disinfect water with chlorine.

Baranyai: “It’s a very effective way of disinfecting, but it continues to disinfect downstream. It’s not selective, usually anyhthing that’s alive, it usually kills. It pretty much sterilizes everything. And that’s how most water treatment plants in our country do that, still.”


Baranyai says in the late 80s, things turned around. His plant added better filters, and now, when they disinfect water, they kill bacteria with ultraviolet light, not chlorine. In just a few years, salmon started spawning – right in the plant. Plus, fresh-water sponges grow in the plant, and herons showed up. Word got around.

Roger Klocek was a biologist at Chicago’s Shedd Aquarium at the time. He learned the news from a fellow scientist.

Klocek: “I thought he was nuts, literally. What are you talking about?”

Klocek says you have to understand, for a long time people ignored water treatment plants or they expected them to remove only the worst industrial pollutants.

Klocek: “I had no idea that waste water plants themselves could actually contribute to an improved ecology.”


Allee: “Maybe the opposite, they were putting chlorine in the water or bacteria, if they weren’t disinfecting.”

Klocek: “Absolutely, you know we hear constantly that technology is going to save us and I really don’t believe that. I think we put too much stock in that, but it sure is gratifying to see when there is some technology that makes a remarkable improvement.”

Klocek says, too often, people assume industrial areas like East Chicago will always be ecological basket cases.

He says, sure there’s room for improvement, but having one concrete example of something that works? That can give you hope about what nature can do if you give it a chance.

Greening the Capital City’s Rooftops

Green roofs are increasing in popularity across the US, especially in cities, where
there’s not a lot of space for gardens. Sabri Ben Achour explores the trend in
Washington, DC, where the city government is promoting the practice for it’s
environmental benefits:

In Washington, you can see flowers and vegetables growing on top of homes,
businesses, even government buildings throughout the city. DC officials say
Washington has nearly 70,000 square feet of rooftop greenery. Only Chicago has
more.

One big fan of these so called green roofs is a popular small hotel, Tabard Inn, just a
few blocks from the White House.

“There’s about 10 varieties of sedum on this roof.”

Sarah Murphy is giving a tour. She’s a horticulturalist.

“This is a very pungent oregano here on the corner, it looks heavily used.”

The city of Washington pays building owners about one-fourth of the cost of
incorporating greenery on rooftops. One big reason? Rainwater runoff.

Sarah Loveland works for an environmental consulting non-profit called DC
Greenworks.

She says Washington has what’s called a combined sewer system. The sewer
system doesn’t just take in what’s flushed down the drain, but also all the rain
running off roofs and streets.

“If you imagine that our sewage treatment plant has a dam, and the sewage system
combines with the storm water system before the treatment plant.”

So, when there’s a heavy rain, that dam at the sewage treatment plant overflows.

“You have both raw sewage and runoff from the streets going directly into the river
untreated.”

Three billion gallons of it a year, at one point.

The EPA sued the District of Columbia.

The city had to spend $150 million to address the problem. Part of that money goes
to green roof grants.

The green roofs slow down rain water – give it some place to soak instead of just
running off straight down the gutter. The city says roofs in the city prevent a million
gallons of storm water runoff from entering the Potomac River.

The roofs also insulate buildings – especially during the summer. Some studies
show they reduce energy costs by 20-30%. And they reduce the heat island effect in
the city, since they don’t get blisteringly hot like traditional roofs.

Green Roofs even offer some habitat for creatures, like bees.

Sarah Loveland with Greenworks, the consultant agency, says rooftop gardens are
also increasingly popular for growing food.

“Veggies are really popular, herbs are really popular – this is a trend that’s taking off
in the restaurant industry. There’s a lot of buzz around it.”

Blueberries and herbs abound in the rooftop gardens of the Tabard Inn, where Paul
Pell is executive chef.

(sound of celery chopping)

“Yeah, we go up and get whatever we want, so it’s fresh. We just climb out the
window when we need it. Chocolate basil goes with ice cream, nasturtiums go with
soups and salads.”

Washington has an advantage over some larger cities in its promotion of rooftop
gardens because federal law prohibits skyscrapers in the nation’s capital, so most
buildings don’t cast shadows over their neighbors.

As a result, most rooftops are sunny – all they need is greenery to soak up the rays.

One group wants part of the economic stimulus package to plug up some leaks. It says old toilets and leaky water pipes below city streets are wasting water. Chuck Quirmbach reports:

The group is called the Alliance for Water Efficiency. It’s made up of plumbing manufacturers, contractors, city water systems, and enviromental groups.

They want about ten billion dollars of the economic stimulus package to go to shovel-ready projects that conserve water.

Alliance board member Susan Stratton says the work could include everything from century-old city water pipes to replacing many older, water-wasting toilets in private homes.

“This requires the skills of a plumber and it requires retailers and wholesalers to deliver products. These are things we know how to do. There are people in the work environment who have these skills and can ramp up pretty quickly.”

Stratton says cutting water use would also save energy by reducing power use at water utilities.

Some cities are looking at taking away parking
on residential streets and replacing it with shallow
ditches full of native plants that filter stormwater.
It’s a way to reduce the polluted runoff that flows
into lakes, rivers and the ocean. As Ann Dornfeld
reports, not everyone is thrilled with the idea:

We’re walking down a winding lane lined with maple trees, tall, dry grasses and
evergreens. Bright white snowberries dot the dark branches. It feels like a walk
in the country. But we’re actually admiring a big-city sewer system.

This little valley – a sort of shallow ditch – is called a “bioswale.” Its plants filter
out pollutants that run off the street. And special, thirsty soil helps the water
absorb into the earth. Sections of the street are narrowed to make room for the
bioswales, so some parking along the street is lost. But houses without
driveways get two parking spaces between the swales.

The bioswales have thick layers of native grasses, shrubs and other plants. It’s
kind of a wild, natural look. Debbie Anderson lives on a nearby street. As she
walks by the bioswale she says to her it just looks messy.

“We think it looked nice when it was first built, but it hasn’t continued to
look good, I don’t think. We moved out here because there was no
sidewalks and the streets were wide open and we like that. Lots of parking,
we can have lots of company. This way you can have, what, two people
that can come? That’s it! No. I don’t want it.”

That’s a pretty familiar argument to Bob Spencer. He’s with the City of Seattle’s
Public Utilities office.

“The big thing is the lack of parking. People really get into using these
street right-of-way shoulders as their personal parking spots.”

But not everybody thinks parking spots are more important than doing something
to reduce water pollution. Spencer says the neighbors on this street actually
competed with other blocks to get these bioswales. It’s free landscaping – and
the city even worked with each homeowner to choose plants that would blend
with their existing garden.

Spencer says the city’s traditional method of dealing with stormwater has washed
contaminants into a nearby creek.

“Well, in the surrounding streets around here, we have what’s called ‘gutter
and ditch’ drainage. And what happens is the water runs off the property
and the impervious streets and rooftops. And it enters a ditch and then
goes pell-mell screaming down to our local salmon-bearing creek, Piper’s
Creek.”

It’s not just Seattle’s creeks that are flooded with runoff. Untreated rainwater
flows straight into lakes and the ocean, polluting them. Cities across the country
are looking for ways to deal with toxic runoff like that.

Spencer says Seattle is pioneering
large-scale natural drainage. In other words, the rain is allowed to drain like it
does in the wilderness. The plant roots slow the water so it can absorb into the
earth. That helps prevent flooding. Pollutants like heavy metals, pesticides
and fertilizers are trapped in the soil, and some of them are broken down in these bioswales.

“So we’ve got a little bit more like a forested system in that we have a duff
layer that acts as a sponge.”

Spencer says the city hasn’t tested the water quality of the runoff that eventually
enters the creek. But he says the runoff has been slowed to a trickle.

“It infiltrates and holds and keeps here 99% of that runoff. So that’s a
pretty large flush of water that’s not entering the creek with this system.”

Officials in Seattle’s city government like the green look of the bioswales. And
they help the city meet federal pollution guidelines. City Council President
Richard Conlin says over the course of three bioswale projects, the city has been
able to lower the cost to about the same as conventional stormwater treatment.

Seattle’s newest bioswale system will be at the foot of Capitol Hill. That’s where
seemingly half of the city’s young people live, in blocks full of apartments,
nightclubs and parking lots.

“It’s actually the densest urban neighborhood west of Minneapolis and
north of San Francisco. So it has a lot of impervious surface.”

Stormwater from Capitol Hill rushes off the hard surfaces and down to a lake. So
the city is taking advantage of new development at the bottom of the hill. It’s
planning to filter the runoff through bioswales before it pollutes the lake.

“And once we’ve done that, I think we’re pretty much ready to say this is
the standard from now on.”

Conlin says the city will likely install bioswales in all new developments, and on
streets where the most runoff enters waterways.

He says cities around the country are contacting Seattle to find out how to install
bioswales of their own.

No New Federal Dollars for Restoration

For the past year, the federal government, states, and
Indian tribes have been devising a unified restoration plan to
clean up and protect the Great Lakes. They released a first draft
this summer. But as negotiations continue, state governments and

For the past year, the federal government, states, and Indian tribes have been devising a
unified restoration plan to clean up and protect the Great Lakes. They released a first
draft this summer. But as negotiations continue, state governments and environmentalists
say the effort is being undercut by a major player. The Great Lakes Radio Consortium’s
Shawn Allee has more:


The first draft of the restoration plan called for dozens of ambitious measures. They
included cleaning up toxic waste and keeping invasive species out of the Great Lakes.
But more than anything, the first draft raised expectations.


“The public response to the draft report that was released this July was very
encouraging.”


David Naftzger is with the Council of Great Lakes Governors.


“Public meetings were held throughout the region and there is broad-based support for
restoring and protecting the Great Lakes.”


State governments generally praised the draft, but questioned the federal government’s
commitment to the effort. Now, they and environmental groups worry their fears were
justified.


Last month, administration advisors issued an internal report that called the first draft of
the plan too ambitious and too costly.


One major sticking point is how to prevent sewage from getting into the lakes. Sewer
upgrades could cost tens of billions of dollars. States want more money, but the
president’s advisors are balking.


Benjamin Grumbles is with the Environmental Protection Agency’s water division.


“We all agree that more work needs to be done on sewer overflows and that the federal
government will continue to provide money, but it’s not realistic to expect an infusion of
that level in the near term.”


Grumbles says federal help’s required to improve sewers everywhere, not just in the
Great Lakes. Grumbles says the administration’s committed to identifying long-term
restoration goals. Administration advisors say continuing negotiations should focus on
short-term measures that require no additional spending.


But David Naftzger says federal leadership should mean more federal dollars.


“This is deeply disappointing, while more can be done with existing resources and there
can be improvements to existing programs, quite simply many of our region’s challenges
require additional funding.”


The plan’s final draft is due next month.


Until then, state governments and environmentalists hope to prod what they see as an
increasingly reluctant partner.

Jump in Great Lakes Beach Closings

A new report says the number of beach closings in the U.S.
increased last year compared to 2003. The report says the number of
closings in the Great Lakes region jumped more than sixty percent.
The Great Lakes Radio Consortium’s Michael Leland has more:


The report by the Natural Resources Defense Council says the number of
closing or health advisory days last year was higher than ever in the
group’s fifteen years of record-keeping.


Throughout the region, there were about three thousand closing or health advisory days in 2004. They say that’s due in part to states monitoring more beaches more often, but also due to
increased sewage and stormwater runoff. Mike Shriberg heads the Michigan environmental group PIRGIM.


“Under the Clean Water Act, we should not be discharging raw or
partialy-treated sewage or, in fact, any polluted water into the U.S. What’s
happening now is we’re having a third-world solution to our sewage problems,
by allowing much raw or partially-treated sewage to flow freely into our
waters.”


The NRDC is calling for tougher enforcement of state and federal clean
water standards, and full federal funding of proposals to modernize sewage
systems along the Great Lakes and other waterways.

Government Releases Plan for Great Lakes Restoration

A coalition led by the federal government is proposing a massive restoration effort for the Great Lakes. Environmental groups say they like most of what’s in the plan, but they’re worried the money to carry it out might not be there. The Great Lake Radio Consortium’s Michael Leland has more.


The draft plan from the government’s task force makes dozens of recommendations. The recommendations include spending billions to modernize municipal sewer systems near the Lakes to cut down on pollution, new federal laws to fight invasive species, and cleaning up some of the Lakes’ most toxic spots.


Andy Buchsbaum is with the National Wildlife Federation’s Great Lakes office. He says a lot’s been done over the last few decades to clean up the Lakes, but there are signs the Lakes are still sick.


“So what you’re seeing is you are seeing real depression of the yellow perch in Lake Michigan, you’re seeing problems with whitefish – they’re sicker and leaner – and you’re seeing some crazy things happen with walleye. Right now there is a good walleye fishery in places, but they were depressed for awhile, and the fluctuations are getting wilder and wilder.”


President George Bush created the Great Lakes Regional Collaboration last year. The task force includes several federal agencies, along with state, local and tribal officials from the region. It also includes representatives from business and conservation groups.


Its members say the group’s draft proposal represents a great opportunity for governments to work together to coordinate the dozens of programs underway throughout the region to restore the Lakes. It can also help bring new money to carrying out those programs. Scott Hassett heads the Wisconsin Department of Natural Resources.


“So if there’s a realistic likelihood of getting the kind of resources and money and brining them to bear, these eight states have to come up with a unified plan, it is a very important point in the process.”


It’s still up in the air how much all this will cost. Environmental groups estimate about twenty billion dollars over the next five years, though the EPA says it’s too soon to put a price tag on the proposal.


Tom Kiernan with the National Parks and Conservation Association. He says the plan is a good one that will make a difference, if Washington and the states commit to paying for it.


“But now we must call the question as to whether federal and state governments will fully fund this plan. If they fully fund the plan, the health of the Lakes and our collective quality of life will improve. If they do not, the Great Lakes as we know them and love them will continue to slowly die.”


The task force will collect public comment on the proposal during the next two months. It also plans to hold five public meetings on the plan throughout the Great Lakes region. The final document’s due out in December.

Report: Sewer Systems Fail to Meet Standards

According to a new report, from an environmental advocacy group,
city sewer systems around the Great Lakes are failing to meet federal
Clean Water Act standards. The Great Lakes Radio Consortium’s Steve
Carmody reports:


The Environmental Integrity Project analyzed data from federal, state and
other sources to compile its review of municipal waste water systems in the
region.


EIP’s Michelle Merkel says researchers found most municipal waste
water sewage systems failed to meet standards to prevent untreated sewage
spills; failed to adequately report the spills when they occurred; or had
inadequate plans to prevent such spills in the future.


Merkel adds, due to a lack of state and federal oversight, the problem may
actually be worse:


“The true extent of the problem is really unknown because the states just aren’t doing a good job of tracking it and making the cities track it.”


To address the problem, The EIP wants the EPA and state regulators to
enforce combined sewer overflow rules, require public notification of spills
within 24 hours and arrange for more federal-state financing for future
sewer improvement projects.

Epa Drops Sewage Blending Proposal

The Environmental Protection Agency has dropped its plans to adopt a controversial policy for sewage treatment plants. The Great Lakes Radio Consortium’s Mark Brush reports:

Transcript

The Environmental Protection Agency has dropped its plans to
adopt a controversial policy for sewage treatment plants. The Great
Lakes Radio Consortium’s Mark Brush reports:


The EPA was planning to sanction a practice known as sewage blending.


Sewage blending is used when treatment plants are hit with large volumes of
storm water. Partially treated sewage is blended with fully treated
sewage, and then released into nearby waterways.


Mike Shriberg is with the Public Interest Research Group. He says the
announcement is a positive step for clean water.


“What would’ve happened if this policy had passed is that sewage blending
would’ve become the end game. It would’ve been what wastewater treatment
plants do to treat sewage anytime that it rains. Now that option is gone.
So the plants that are doing it now have just been told that they need to
fully treat sewage in the future.”


The EPA said it dropped its proposal after receiving more than 98,000 public
comments. The announcement came shortly before Congress
was to vote on a bill to stop the sewage blending proposal.

An Alternative to Waste Incinerators

  • A new process called alkaline hydrolysis is forecasted to be a cheaper, safer way to dispose of animal carcasses. (Photo by Dr. Beth Williams, University of Wyoming, courtesy of CWD Alliance)

Animal research labs usually get rid of carcasses by burning them in incinerators. Now, a new more environmentally friendly technology is being used to dispose of the diseased dead animals and the lab supplies they contaminate. The new method has worked well enough that hospitals are considering it as a way to dispose of medical waste. The Great Lakes Radio Consortium’s Julie Halpert reports:

Animal research labs usually get rid of carcasses by burning them in incinerators. Now, a new more environmentally friendly technology is being used to dispose of the diseased dead animals and the lab supplies they contaminate. The new method has worked well enough that hospitals are considering it as a way to dispose of medical waste. The Great Lakes Radio Consortium’s Julie Halpert reports:


Until recently, the only safe way to destroy diseased tissue and other infectious waste was to burn it in an incinerator. But dangerous chemicals such as dioxins spew from the incinerator smokestacks, and burning leaves behind a toxic ash.


(sound of machine whirring)


Now, there’s an alternative to burning. Dr. Gordon Kaye stands in a spotless room beside one of the units manufactured at a company he helped found, WR Squared, in Indianapolis, Indiana. The unit will eventually be used to dispose of 5,000 pounds of dead animals – about the equivalent of five large cows – that were used for veterinary research.


But there will be no smoke. There’ll be no fire.


Kaye’s idea for a new type of disposal technology began 12 years ago when he was a pathology professor at Albany Medical College. He was frustrated with how much it cost to dispose of dead research animals. So, he started experimenting with a new technology. And alkaline hydrolysis was born.


“Well, there are no air emissions from it. It’s a sealed system. It takes place in a hermetically sealed pressure vessel. No dangerous products are produced in it because of the temperature which it takes place.”


Alkaline hydrolysis works like this: infectious waste goes into a tightly sealed vessel, along with strong alkalis which are very caustic. The waste is then cooked at temperatures well above boiling. A chemical reaction causes the waste to break down. The infectious components are neutralized. When it’s over, you end up with two products: a sterile, water-like solution, that can head to a sanitary sewer system, and sterile crushed bones, the consistency of powder, that can be used as fertilizer. Because the end products are clean, they don’t require complicated disposal, so the process is cheaper than incineration.


WR squared now has 60 units in 15 states, primarily at research facilities. The U.S. Department of Agriculture has purchased several of them. New York was the first state to allow use of the technology. Ira Salkin directed that state’s medical waste program when it approved WR squared’s process.


“It has less potential problems than is being found with incineration and the use of incineration in the U.S. is decreasing and therefore their system holds great promise. As the numbers of incinerators decrease, one finds they have this alternative to be used to treat pathologic material.”


Environmentalists agree with Salkin that the technology is sound. Horhay Emmanuel is with Health Care Without Harm. He notes that it’s especially effective for one troublesome type of waste, cattle dead from Mad Cow disease.


“Not only does it destroy infectious agents, but it also destroys prion-contaminated waste. And prions are what are believed to cause things like Mad Cow disease, which are difficult to destroy, even by incineration, so WR squared has been shown to destroy these prions in the contaminated waste.”


Last April, The Environmental Protection Agency approved alkaline hydrolysis, along with incineration, as a way to treat Mad Cow diseased waste. And WR Squared’s Gordon Kaye sees that as a big future market.


Horhay Emmanuel, with Health Care Without Harm, says while alkaline hydrolysis is generally good for the environment, there is one concern. The fluid that’s produced could overwhelm some small town’s sewer systems. The company says in communities with small sewer systems, the solution can be released more slowly or during off-peak hours.


So, alkaline hydrolysis process is cheaper, it pollutes less, government agencies like it, and environmentalists find little to criticize.
Now, the company is broadening its reach to treat hospital waste. Many hospitals are using smaller, not very efficient incinerators that pollute more.


WR Squared’s Gordon Kaye says he expects big growth with this new method to dispose of medical and infectious waste as labs and hospitals look for ways to replace their incinerators over the next several years.
