Some planning experts are worried that the rapid development in cities and suburbs is
paving over too much land and keeping water from replenishing aquifers below ground.
The Great Lakes Radio Consortium’s Lester Graham reports:


In nature… when it rains… the water slowly soaks into the ground and makes its way
through the soil and rock to eventually be stored as groundwater. Some of it makes its
way underground to be stored in aquifers. And some of it slowly seeps through the rock
for a while and then resurfaces as springs to feed streams during times when there’s not a
lot of rain. It’s a natural storage system and a lot of cities rely on that water.


But when we build buildings and houses and parking lots and roads, a lot of the land
where the rain used to soak into the ground is covered up. Instead the rainwater runs off
the hard surfaces and rushes to stormwater gutters and ditches and then overloads creeks
and rivers. Even where there are big expansive lawns in the suburbs… the rain doesn’t
penetrate the ground in the same way it does in the wild. The grass on lawns has shallow
roots and the surface below is compact… where naturally-occurring plants have deep
roots that help the water on its way into the earth.


Don Chen is the Executive Director of the organization Smart Growth America. His
group tries to persuade communities to avoid urban sprawl by building clustering houses
and business districts closer together and leave more natural open space.


“With denser development you have a much lower impact per household in terms of
polluted runoff.”


Chen says the rain washes across driveways and parking lots, washing engine oil, and
exhaust pollutants straight into streams and rivers instead of letting the water filter across
green space.


Besides washing pollutants into the lakes and streams… the sheer volume of water that
can’t soak into the ground and instead streams across concrete and asphalt and through
pipes can cause creeks to rise and rise quickly.


Andi Cooper is with Conservation Design Forum in Chicago. Her firm designs
landscapes to better handle water…


“Flooding is a big deal. It’s costly. That’s where we start talking about economics. We
spend billions and billions of dollars each year in flood damage control.”


Design firms such as Cooper’s are trying to get developers and city planners to think
about all that water that used to soak into the ground, filtering and being cleaned up a bit
by the natural processes.


Smart Growth America’s Don Chen says those natural processes are called infiltration….
and Smart Growth helps infiltration…


“And the primary way in which it does is to preserve open space to allow for natural
infiltration of water into the land so that there’s not as much pavement and hard surfaces
for water to bounce off of and then create polluted runoff.”


People such as Chen and Cooper are bumping up against a couple of centuries or more of
engineering tradition. Engineers and architects have almost always tried to get water
away from their creations as fast and as far as possible. Trying to slow down the water…
and giving it room to soak into the ground is a relatively new concept.


The U.S. Environmental Protection Agency is trying to get communities to give the idea
some consideration. Geoff Anderson is the Acting Chief of Staff for the EPA’s Office of
Policy, Economics and Innovation.


“Anything you can do to keep that water on site and have it act more like it does in its
natural setting, anything you can do to sort of keep that recharge mechanism working,
that’s helpful.”


The EPA does not require that kind of design. It leaves that to local governments and the
private sector. The Conservation Design Forum’s Andi Cooper says sometimes getting
companies to think about treating water as a resource instead of a nuisance is a hard
sell…


“You know, this is risky. People tell us this is risky. ‘I don’t want to do this; it’s not the
norm.’ It’s becoming less risky over time because there are more and more
demonstrations to point to and say ‘Look, this is great. It’s working.’ ”


But… corporate officials are hesitant. Why take a chance on something new? They fear
if something goes wrong the boss will be ticked off every time there’s a heavy rain.
Cooper says, though, it works… and… reminds them that investors like companies that
are not just economically savvy… but also have an environmental conscience.


“A lot of companies are game. They’re open. If we can present our case that yes, it
works; no, it’s not risky; it is the ethical thing to do; it is aesthetically pleasing; there are
studies out there that show you can retain your employees, you can increase their
productivity if you give them open spaces to walk with paths and make it an enjoyable
place to come to work everyday.”


So… doing the right thing for the environment… employees… and making investors
happy… make Wall Street risk takers willing to risk new engineering to help nature
handle some of the rain and get it back into the aquifers and springs that we all value.

An Environmental Protection Agency official wants local governments to take a broader view
when making land use plans for their communities. The Great Lakes Radio Consortium’s Lester
Graham reports:


Often planners don’t look past their own city borders when making decisions. Geoff Anderson
wants that to change. He’s the Acting Chief of Staff for the EPA’s Office of Policy, Economics
and Innovation. Anderson says city officials often look at land use planning one site at a time
instead of looking at how their decisions will affect the entire area…


“The two scales are very important and I think in many cases too much is paid to the site level
and not enough is given to the sort of broader regional or community context.”


Anderson says that’s especially important when planning for stormwater drainage. He says too
many communities think about getting the water to the nearest stream quickly without thinking
about how that rushing water might affect flooding downstream.

Thirsty City Waits for Water Diversion Law

  • Diversion of water from the Great Lakes is a controversial issue. Many worry that diversion could affect life in the ecosystem. Others worry about obtaining sources of fresh water for drinking. (Photo by Brandon Bankston)

Great Lakes governors and their counterparts in Canada are working on a legal agreement called Annex 2001. The document will determine how water from the Great Lakes will be used and who gets to use it. Controversy has already erupted over the possibility of one city’s bid for the water.

Great Lakes governors and their counterparts in Canada are working
on a legal agreement called Annex 2001. The document will determine how
water from the Great Lakes will be used and who gets to use it. Controversy
has already erupted over the possibility of one city’s bid for the water.
The city is looking toward the completed Annex for guidance. The Great
Lakes Radio Consortium’s Christina Shockley reports:


Dan Duchniak says he’s an environmentalist.


“We have the low-flow showerheads in our house, we have the low-flow faucets, we have the high-efficiency washers and dryers, our kids know about those, you know, they think they’re fun.”


But Duchniak is in the middle of a bitter fight with other environmentalists and officials over his area’s largest natural resource: water from Lake Michigan. Duchniak is the water manager for the City of Waukesha, Wisconsin. It’s just west of Milwaukee. Waukesha is only about 20 miles from the Lake Michigan shore. Right now, Waukesha gets its water from wells that tap an aquifer deep within the ground. But Duchniak says the wells won’t sustain the long-term needs of the city.


“As the water levels drop, the water quality degrades, and what happens is we’ve seen an increase in different water quality parameters, one of those being radium.”


And radium is a health problem. In very high doses, radium can cause bone cancer. To solve its water problems, the City of Waukesha might ask for access to Lake Michigan water. But even though the community considers the lake part of its back yard, there’s a major problem. Even though it’s close, Waukesha sits outside the Great Lakes basin.


That means the area’s ditches and streams drain away from the lake. Rain water runoff and treated water from the sewer system flow toward the Mississippi River Basin. The governors and premiers might include a rule in the Annex 2001 that says communities sitting outside the Great Lakes basin must return treated water to the lake, if they use it.


Engineers who study water in the area say Waukesha could make the case that the city is already using Great Lakes water. That’s because the city’s wells tap into water beneath the surface that supply water to Lake Michigan. But environmentalists say that argument isn’t going to fly. Derek Sheer is with the environmental group “Clean Wisconsin.” He says Waukesha would be pumping a lot more water directly from the lake than the underground aquifer would replace.


“They’re not returning 13 million gallons of water back to the Great Lakes by any stretch of the imagination.”


But the city of Waukesha knows that if the finalized Annex 2001 looks anything like the early drafts, the city would have to return most of the water it uses back to the lake. Waukesha’s water manager, Dan Duchniak says that could be done in a combination of ways. The city could pump it back to the lake, pump it to a nearby stream that flows to the lake, or stop using the ground water completely and let it flow back to the lake.


People on both sides of the water issue seem to agree on one thing: because of the huge amount of water in the Great Lakes system, and its natural ebb and flow, the amount of water the City of Waukesha would take would not harm the Great Lakes’ ecosystem. Even if it’s not pumped back.


Art Brooks is a professor at the Center for Great Lakes Studies at the University of Wisconsin-Milwaukee.


“The amount of water they intend to withdraw would probably lower the level of Lake Michigan on the order of a millimeter or so, probably less that five millimeters per year.”


But it’s not just Waukesha that has environmentalists worried. Professor Brooks and environmentalist Derek Sheer say if Waukesha gains access to Great Lakes water, it could set a dangerous precedent. Sheer doesn’t want other states and countries to start withdrawing Great Lakes water.


“If Waukesha and Arizona and Georgia and all these other places start pumping large amounts of water out of the basin, we could see a dramatic lowering of the water in the lakes.”


The city of Waukesha says it needs the water and would abide by whatever the Annex 2001 agreement sets down. And Waukesha’s water manager, Dan Duchniak, says that includes what it determines about return flow. He says arguing about the issue right now is a waste of time, since the Annex isn’t done. Beyond that, Duchniak says Waukesha is part of the Great Lakes system, and is not about to suck the lakes dry.


“Lake Michigan is in our back yard. We can see Lake Michigan from here. We’re not that far away from it.”


The experts say Waukesha would only be the first in line to ask for Great Lakes water. With suburbs sprawling away from the big cities on the lakes more and more towns will be eyeing the Great Lakes when demand for water exceeds their underground supplies.


A draft of the Annex could be ready this year, but it will most likely go through a lengthy series of votes before it becomes law.

Wind Turbines Stir Up Neighbors (Part 2)

Most people think renewable energy is a good idea. It’s better
than burning fossil fuel to create electricity. But “green energy”
alternatives
can be controversial. Windmill farms are springing up all across the
nation.
Some people think the windmills are eyesores. But others say windmill farms
can help preserve the agricultural landscape by supplementing the income of
farmers. In the second of a two-part series on wind energy, the Great Lakes

Most people think renewable energy is a good idea. It’s better than burning fossil
fuel to create
electricity. But “green energy” alternatives can be controversial. Windmill farms
are springing
up all across the nation. Some people think the windmills are eyesores. But others
say windmill
farms can help preserve the agricultural landscape by supplementing the income of
farmers.
The Great Lakes Radio Consortium’s Linda Stephan reports:


For 30 years, Matt Mauer raised crops and livestock on his farm about 10 miles from
the Lake
Michigan shoreline. Today, he’s in his backyard looking at the land now farmed by
his daughter
and son-in-law. Standing there, he feels a crop they’re not harvesting.


“The good Lord makes it windy all the time for us, so let’s use it, you know.
Because I’m like
everybody else. When I get up in the morning, I want lights.”


Mauer’s hoping to put four wind turbines on his family’s farm near Ludington,
Michigan. That
would power about 24-hundred homes. Nearby, a renewable energy company’s working with
other farmers to build a hundred turbines in the area. Mauer says many of his
neighbors want in
on the deal because they think wind energy could help save their farms.


“It’s hard to make a living just farming right now. And I consider the wind one of
the crops that
we could harvest. It will help keep farmers on the land. Like if, in this place, if
we could get
seven–thousand dollars a year, six-thousand dollars a year for four of them, that’d
make it a hell
of a lot easier to keep the people here and farm.”


The state government’s backing similar projects. It’s training financial advisors
to show farmers
how they can turn a profit with windmills.


But not everyone likes the idea. Some people who live in the area around the
planned windmills
say they’re worried the towers would destroy the region’s charm. That’s linked to
property values
and to tourism. And they don’t like the size of the proposed windmills. Each one
would be four-
hundred feet tall. The blades would have a diameter nearly as long as a football
field.


It’s a story that’s heard in many places. Cape Cod, Massachusetts, the prairies of
Illinois, and
around the Great Lakes. For example, a Michigan couple who wanted large-scale
turbines on
their property ended up losing a court-battle against local government that opposed
the plan. And
two turbines already in place in Mackinaw City – between Lake Michigan and Lake
Huron –
have some unhappy neighbors as well.


Thomas and Virginia Alexander’s home is about 15-hundred feet away from the windmills.
They’re in their eighties and they both wear hearing aids… but even without them,
they say the
windmills are loud…


Tom Alexander: “There’s things about it we don’t appreciate, at times the noise –
not always –
depending upon the wind and the direction.
Virginia Alexander: “Yesterday. Very noisy yesterday. The wind was high and they,
you could
really hear them.”
Tom Alexander: “Just a continual swish, swish, swish, swish, swish.”


Windmill developers say the sound is no louder than normal speech. But this noise is
different. It
goes beyond the frequencies of normal speech. The sound can travel long distances
through both
the ground and the air. They keep Virginia Alexander awake some nights.


Tom and Virginia Alexander’s son Kelly lives next door with his family. He calls
himself a
windmill victim. He has this advice for others:


“Don’t let them go in your backyard. There are places they can go. You don’t just
put those in
somebody’s backyard. I don’t think it’s right.”


A lot of people agree with the Alexanders. Even wind energy boosters concede that
location is
key to successful projects. David Johnson heads up the program for the state of
Michigan that’s
encouraging farmers to allow windmills on their land. He says turbines should be
constructed
where there’s lots of wind and few neighbors. But he says when people say ‘no’ to
windmills,
they should consider the alternative.


“So, does that mean that you should build another big coal-fired plant? Is that the
preferable way
of doing it with the global warming impacts and the mercury pollution and so on that
go with
that? Is that the choice that the public wants to make?


States across the nation are struggling to find the right balance between clean
energy and the
beauty of an uncluttered landscape. Few regulations are in place right now. More
and more,
communities will be facing the decision of whether clean energy and keeping farmers
on the land
is worth the price of adding wind turbines to the scenery.

Tribal Governments Demand Role in Annex 2001

Tribal and First Nation governments from the Great Lakes region say they’re being left out of negotiations to craft a sweeping new framework for regulating Great Lakes water. The Great Lakes Radio Consortium’s Sarah Hulett reports:


Representatives from about 75 Native American communities in the U.S. and Canada are demanding a more prominent role in the decision-making process for the agreement known as Annex 2001. The agreement aims to limit Great Lakes diversion. But many tribal groups say the draft agreement is weak.


The Council of Great Lakes Governors says it plans to invite tribal groups to a forum shortly after the New Year. Frank Ettawageshik is the tribal chair of the Little Traverse Bay Bands of Odawa Indians, in northern michigan. Ettawageshik says he has yet to see the offer. But he says tribal governments don’t just want to be consulted as Indian communities.


“Of course, the governments are made up of many communities. But it’s not just a matter of wanting community input. It’s a matter of wanting input at a government-to-government level.”


The Council of Great Lakes Governors is handling Annex negotiations. The eight governors and two premiers are expected to sign the agreement sometime next year.

Outdoor Lab Forecasts Global Warming Effects

Scientists from around the world are studying how higher levels of carbon dioxide will affect forests 100 years from now.

Scientists from around the world are studying how higher levels of carbon dioxide will affect forests 100 years from now. They’re doing that by pumping higher levels of CO2 and ozone into stands of trees. The Great Lakes Radio Consortium’s Mike Simonson visited the experimental forests and has this story:


(sound of “quiet area”)


The north woods of the Great Lakes states are stands of millions of acres of pine, maple, birch, and aspen forests. It’s a perfect place to try to figure out how trees will react to the higher levels of ozone and carbon dioxide scientists expect in the future.


(sound of beeping fence gate)


The first thing you notice at Aspen Free Air Carbon Dioxide Enrichment Project – Aspen FACE for short – is two huge tanks inside the fenced in enclosure. Each one is bigger than an 18-wheel tanker truck. They’re full of carbon dioxide… CO2. So much CO2 is used in this experiment, the tanks are filled twice a day.


(sound of filling tanks)


If you looked at the site from an airplane, you’d see 12 circular tree stands surrounded by 30 foot high pipes. Those pipes pour CO2 or ozone gases or both into the air surrounding birch, sugar maple, and aspen trees. The scientists know that greenhouse gases in the earth’s atmosphere have been increasing. They believe two centuries of industrial pollution has contributed to the problem. And they expect the CO2 and ozone levels to double by the end of this century. They’re raising the level of greenhouse gasses in different mixes to see what the predicted levels will do to forests.


This open air project is different than previous experiments. David Karnosky is with Michigan Tech. He’s the Project Manager for Aspen FACE. He says before these kinds of projects, they just tested trees inside places like greenhouses.


“We needed to get out of those chambers. We needed to have a more realistic, real world sort of situation where we had multiple trees. We wanted real intact forest communities. We didn’t want to have just a small number of trees inside of a chamber.”


The United States Department of Energy launched this experiment in Wisconsin’s northwoods seven years ago. Karnosky says they’re learning how the trees react to the higher CO2 levels, and that could shape the future of the world’s timber industry.


“Who will be the winners? Who will be the losers? Will aspen or birch or sugar maple? In northern Wisconsin here we’ve got probably 40 million acres of those species mixes. What’s going to happen under elevated CO2 in the next 100 years? Will these forests remain as they are?”


(sound of driving on gravel)


Driving to one of the experimental circles, we pull up to a ring of trees. Mark Kubiske is one of the two full-time on-site researchers.


“Now this particular ring is an elevated CO2 plot. CO2 is delivered through this copper pipe. It runs to that fan, there’s a large fan right on the end of that gray building.”


The scientists have found that trees in the CO2 circles grow 30 percent faster than trees without the gas.


“The trees are larger in diameter, they’re straight, they have lots of leaf area, they just look very healthy. That is just in tremendous contrast to the ozone ring. We’ll go up around the corner and look at one.”


Nearby another circle of trees is not doing nearly as well. The trees are skinny, twisted not as tall as the other sites. Higher ozone levels are hurting the trees.


At the sites where pipes emit both ozone and CO2, the tree growth seems normal – except for some stunted maple trees. The leaves of the aspen and birch take in much of the CO2, convert it to sugar which goes to its roots, eventually becoming a natural part of the soil. That suggests forests may help alleviate gases that cause global warming. The Project Director, David Karnosky says CO2 and ozone appear to cancel each other out. But he says it’s too early to draw any firm conclusions. Ultimately, he says governments will be able to look at this glimpse into the future and try to come up with emissions policies that help.


“The whole issue of the Kyoto protocol, our government not signing off on that. There’s been some relaxing of the feelings from what I’ve seen from the President’s report now that they’re beginning to realize that elevated CO2 is having an impact on global warming and could be impacting our plant communities.”


Karnosky says it’s possible that besides reducing emissions, governments might determine that planting more trees might be very helpful in reducing greenhouse gasses worldwide.

Is Sewage an Untapped Energy Source?

  • Who would've thought that sewage could produce electricity? The University of Toronto's David Bagley did. (photo by Davide Gugliemo)

A Toronto researcher says most communities are underestimating a potential source
of cheap electricity – raw sewage. The Great Lakes Radio Consortium’s Karen Kelly reports:


University of Toronto professor David Bagley collected waste water at a North
Toronto water treatment plant. He took the sewage into his lab, dried it and
then burned the solids to see how much energy they produced. He estimates the
energy produced from sewage at three treatment plants could produce more than
100 megawatts of electricity. That could be enough to keep a small town going
for a year. But Bagley says few take advantage of this resource.


“Our measurements show that there’s enough energy that we should be able to
completely offset the electricity needed to run the plant, and have extra
left over the send back to to the grid.”


Bagley finds communities are reluctant to invest in the equipment they’d
need to convert sewage into power. But he’s hoping to to design a cheaper
and more efficient system so more people can get the most out of their sewage.

Seeking Answers to Spring Sewage Dumpings

One of the biggest dumpers of raw sewage into the Great Lakes this year may be heading toward a solution that puts the clean-up burden on local citizens. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:


Several cities dumped sewage into the Great Lakes during heavy rains this spring and summer. Milwaukee’s overflow total was about five billion gallons. A task force set up by Milwaukee’s mayor concludes much of the problem came from rainwater leaking into the sewer system through illegal hookups and cracked pipes between homes and sewer mains. Mayor Tom Barrett says reducing the so-called infiltration and inflow, or, I and I, will be expensive.


“Well, we’re obviously going to have to put more dollars into I and I in Milwaukee. The city has done that, we’re doing more in this budget, we’re going to continue to do more… I think each of the communities is going to have to face that issue.”


The “communities” are the roughly 30 smaller cities that use the Milwaukee sewer system. Wisconsin’s attorney general is trying to ge the city and suburbs to work together. Milwaukee and many other Great Lakes cities are also asking the U.S. government to spend more money on reducing sewer overflows.

Report: Renewable Energy Can Kickstart Job Growth

  • Turbines like these not only could help produce energy from a renewable and seemingly infinite resource, but could also create thousands of new jobs, according to the Union of Concerned Scientists.

A new report says a national renewable energy policy could create thousands of new
jobs in the Midwest. The Great Lakes Radio Consortium’s Erin Toner reports:


The report by the Union of Concerned Scientists urges Congress to adopt a policy
requiring 20 percent of the nation’s energy to be produced using renewable sources
by the year 2020. Those sources could be wind, solar, or geothermal energy. The report
says such a policy could create thousands of new jobs in manufacturing, construction and
maintenance.


Jeff Deyette is an energy analyst with the Union of Concerned Scientists. He says
rural communities – especially farmers – could be the biggest winners under the proposal.


“Farmers that were chosen to have wind power facilities sited on their land could get up
to as much as $4,000 per turbine to lease on their property.”


Deyette says a national renewable energy standard could save consumers nearly 50 billion
dollars by 2020. He says that’s because increased competition from renewables would help
lower the demand and the price of natural gas.

Epa Calculates Illnesses Caused by Sewage Overflows

Sewage overflows during heavy rains have long been implicated in
illnesses in people. For the first time, the Environmental Protection
Agency has come up with an estimate of just how many people are getting
sick from swimming at contaminated beaches. The Great Lakes Radio
Consortium’s Tracy Samilton reports:


The EPA estimates that somewhere between 3,500 and 5,500 beachgoers get sick
every year when untreated sewage is flushed into rivers, streams and lakes
by heavy rains. The EPA’s Ben Grumbles says the report is another reason
for cities to fix their aging sewage systems – despite the high cost.


“And it can literally add up to hundreds of millions, a couple of billion dollars, for
very large cities, to fix the problem for the long-term.”


Grumbles says many communities can avoid that bigger expense by investing
in new technologies to better manage existing systems – and keeping pipes
well-maintained and free of debris.


Environmental groups say they hope legislators are listening. Congress just reduced
the fund from which communities can get loans for sewer projects by 500 million dollars.
