In the Great Lakes region, farmers are one of the biggest users of water. They
pump water from underground aquifers or from lakes and streams to irrigate their
crops or water livestock. Agriculture has been criticized for its large withdrawals
of water. Farmers say they want to be recognized in a Great Lakes water use
agreement as efficient water users, but as Erin Toner reports… it’s unclear
whether that’s true:

The series, Ten Threats to the Great Lakes is now looking at the threat of water withdrawals from the Great Lakes. Our guide through the series is Lester Graham. He says a lot of businesses and homes use water from the basin, but one group says its use is especially efficient.


In the Great Lakes region, farmers are one of the biggest users of water. They
pump water from underground aquifers or from lakes and streams to irrigate their
crops or water livestock. Agriculture has been criticized for its large withdrawals
of water. Farmers say they want to be recognized in a Great Lakes water use
agreement as efficient water users, but as Erin Toner reports… it’s unclear
whether that’s true:


Scott Piggott is the sixth generation to grow up on his dad’s cattle farm in a small
town in central Michigan. He says not everything on the farm is perfect, but he
says he grew up knowing that you have to do things right to protect the
environment.


“If we don’t begin to stand up and say, look, this is what we’re doing to protect
the environment, I think more people will continue to say, hey, they’re not telling
us what they’re doing, they must be doing something wrong.”


Piggott also works for the Michigan Farm Bureau. He says his goal is to make
sure every farm in his state is doing everything it can to protect the environment,
including conserving water they use for irrigation.


But Piggott and the farm bureau oppose broad regulations for large water users,
such as farmers. That’s proposed in a draft of a Great Lakes regional water use
agreement. Piggott argues the agreement should treat farmers differently because
the water they use goes right back into the ground.


Piggott said in a Farm Bureau press release that, “95 percent of the water that
touches a farm field seeps into the soil providing aquifer recharge.”


Later, he qualified his statement.


“It is estimated that 95 percent of the water that touches an open, pervious space
seeps into the soils and a portion of that, which I would infer that, it does provide
aquifer recharge, but necessarily does all 95 percent of it go towards aquifer
recharge. I think that might be debated. The quote could probably be stronger in
a given direction, but I stand by it.”


Piggott says his information is based on Environmental Protection Agency
estimates. But is his 95 percent figure true?


Jon Bartholic is with Michigan State University. He’s done research on water
use on farms. He says of all the water that falls on a farm – that’s rainfall and
irrigation – about 70 percent of it evaporates.


“So the remaining part, 30, 40 percent depending where you are. It might be
almost 0 percent, if you’ve got clay soil and it’s all run off, is there to potentially
to go back and recharge the aquifer.”


Bartholic’s estimate is that 30 to 40 percent potentially flows back into the Great
Lakes basin and its aquifers – that’s nowhere near 95 percent. Bartholic says farmers
do consume water.


“Clearly, farmers are being very conscientious about their water use, but, yes, if
you use water for crops and have economic value, there is some consumptive
usage of that water.”


Other water experts in the region say the issue is complicated. A lot of factors
effect how much water used to irrigate crops actually gets back to the aquifer.
Although one expert says at best the 95-percent estimate is “theoretically
possible” if conditions were perfect.


Conditions are rarely perfect.


Mark Muller is director of the Environment and Agriculture Program with the
Institute of Agriculture and Trade Policy in Minneapolis. Muller says it’s
generally agreed that right now there’s plenty of groundwater in the Great Lakes
region, but he says there is still reason for concern. That’s because in other areas of the
country, aquifers thought to be plentiful have gone dry.


Muller says managing Great Lakes water resources is important for the close to
40-million people who rely on the basin for their drinking water. He says
managing that water correctly is also crucial to sustaining the region’s farming
industry.


“Industry and agriculture is going to look at the Great Lakes basin as a place
where they should set up shop. So, I think we should realize that we have a very
valuable resource that’s only going to become more valuable in future years.”


Muller adds that public opinion is very important to shaping the Great Lakes
regional water use agreement. He says any misleading information, from any of
the stakeholders, is just not helpful. That’s why the farm bureau’s claim that 95-
percent of the water used for irrigation recharges the aquifers is more important than
just an optimistic viewpoint. It’s seen by some as a public relations spin.

Ten Threats: Air Pollution Into Water Pollution

We’re continuing our series, Ten Threats to the Great Lakes. Our guide through the series is Lester Graham. In this report he explains one of the threats that experts identified is air pollution that finds its way into the Great Lakes:

Transcript

We’re continuing our series ‘Ten Threats to the Great Lakes’. Our guide through the
series is Lester Graham. In this report he explains one of the threats is air pollution that
finds its way into the Great Lakes:


It’s called ‘Air Deposition.” Melissa Hulting is a scientist at U.S. Environmental
Protection Agency. We asked her just what that means:


“Air deposition simply is just when materials, in this case pollutants, are transferred from
the air to the water. So, pollutants in particles can fall into the water. Pollutants in rain
can fall into the water, or pollutants in a gas form can be absorbed into the water.”


So, it’s things like pesticides that evaporate from farm fields and end up in the rain over
the Great Lakes. PCBs in soil do the same. Dioxins from backyard burning end up in the
air, and then are carried to the lakes


One of the pollutants that causes a significant problem in the Great Lakes is mercury. It
gets in the water. Then it contaminates the fish. We eat the fish and mercury gets in us.
It can cause babies to be born with smaller heads. It can cause nervous system damage
and lower IQ in small children if women of childbearing age or children eat too much
fish.


One of the notable sources of mercury is from power plants that burn coal.


(Sound of coal car)


Railroad cars like this one empty their tons of coal at power plants all across the nation.
More than half of the electricity in the nation is produced at coal-burning power plants,
and with a 250-year supply, coal is going to be the primary fuel for a while.


One coal producing state is acknowledging that mercury is a problem. Doug Scott is the
Director of the Illinois Environmental Protection Agency. He says coal is important to
the energy mix, but we need to reduce pollutants such as mercury as much as possible.


“The policy of the state has been to try to work with the power plants to try to burn
Illinois coal as cleanly as you can. Now, that means a lot more equipment and a lot more
things that they have to do to be able to make that work, but we’re committed to trying to
do both those things.”


And, Scott says the federal government’s mercury reduction program does not go far
enough soon enough, but the electric utility industry disagrees.


Dan Riedinger is spokesman for the Edison Electric Institute, a power industry trade
organization. Riedinger says, really reducing mercury emissions at power plants just
won’t make that much difference.


“Power plants contribute relatively little to the deposition of mercury in any one area of
the country, including the Great Lakes, and no matter how much we reduce mercury
emissions from power plants in the Great Lakes Region, it’s really not going to have a
discernable impact in terms of improving the levels of mercury in the fish people want to eat.”


“Relatively little? Now, that flies in the face of everything I’ve read so far. Everything
I’ve read, indicates coal-fired power plants are a significant contributor to the mercury
issue in the Great Lakes and other places.”


“It’s really not quite that simple. Power plants are a significant source of mercury
emissions here in the United States, but most of the mercury that lands in the Great
Lakes, particularly in the western Great Lakes is going to come from sources outside of
the United States.”


Well, it’s not quite that simple either. The U.S. EPA’s Melissa Hulting agrees some of
the mercury in the Great Lakes comes from foreign sources, but recent studies show
some mercury settles out fairly close to the smokestacks. She says you can blame both
for the mercury in your fish.


“You blame the sources that are close by and you blame the sources that are far away.
The bottom line with mercury is that we’re all in this together and it’s going to take
everybody reducing their sources to take care of the problem.”


Taking care of the problem is going to take some money, and that will mean we’ll all pay in
higher utility bills. The Illinois EPA’s Doug Scott says it’ll be worth it if we can reduce
mercury exposure to people.


“We know what the issue is. It’s not a matter of us not understanding the connection
between mercury and what happens in fish, and then what happens in humans as a result
of that. We understand that. We know it, and we also know to a great degree what we
can do to try to correct the problem, and so, it’s a matter of just going out and doing it,
and so I’d like to think it’s something that can be done sooner rather than later.”


And since Great Lakes fish have elevated levels of mercury, sooner would be good.
It’ll take a while for the mercury already there to work its way out of the ecosystem and
return to more normal levels.

Ten Threats: Coaster Brook Trout

A lot of native fish have been hurt by pollution, invasive species and changes we’ve
made on the lake, but one fish stands out. For anglers, the Coaster Brook trout might have
been the greatest Great Lakes fish. It was abundant, fun to catch and lived in the cleanest
water, but throughout the 20th century, its populations declined just as the health of the
lakes did. Now, slowly, a diverse group of people is trying to save the fish in an effort
that could improve the Great Lakes too. The Great Lakes Radio Consortium’s Chris

A lot of native fish have been hurt by pollution, invasive species and changes we’ve
made on the lake, but one fish stands out. For anglers, the coaster brook trout might have
been the greatest Great Lakes fish. It was abundant, fun to catch and lived in the cleanest
water, but throughout the 20th century, its populations declined just as the health of the
lakes did. Now, slowly, a diverse group of people is trying to save the fish in an effort
that could improve the Great Lakes too. The Great Lakes Radio Consortium’s Chris
McCarus reports:


(Sound of river waterfall)


Hundreds of feet above Lake Superior, the Salmon Trout River flows fast and falls hard
onto a rocky bottom below. Much of the river lies within a large tract of private woods
and hills. It’s been untouched for about a century.


Peter Dykema and his family are part owners of the land. He speaks with affection about
fishing for coaster brook trout here as a kid.


“Well as you can tell it’s a beautiful river and there’s nothing a 14 year old boy would
rather do than get his feet cold and wet and throw flies into trees. So, I did it every
chance I had.”


Dykema is nostalgic because those days are long gone for almost everybody. He’s part
of a group of activists trying to restore the coaster brook population.


Coaster brook trout have sparkling colors. They’re even more colorful than Rainbow
trout, and they grow a lot bigger. They can reach 2 feet and 4 pounds. These indigenous
fish used to live in 200 streams around Lake Superior. People came from all around the
nation to fish for them. Presidents Roosevelt and McKinley came to Michigan to catch
them, and they were caught by the boatload.


Over fishing was one of the biggest reasons why they were nearly wiped out. Their
habitat was damaged from mining and road building. Silt filled in the rock bottom where
they like to lay their eggs. That also hurt the fish.


Logging damaged the coaster brook’s habitat. Scott Libants is a fish and wildlife
researcher at Michigan State University. He says loggers dammed up streams to flood
them. Then they packed them with logs. When they had enough, they broke the streams
back open so the logs would float down to the lake to be sold.


“You knock the dam out and send all the trees down. You scour the watershed. It’s like
flushing a toilet.”


The fish haven’t recovered since. They just couldn’t take the abuse.


The Salmon Trout River still has them because the private landowners banned fishing
and didn’t alter the land. It’s one of only a handful of streams in the U.S. and Canada
that still has the coaster brook trout.


(Sound of people walking in the woods)


Downstream on the way to Lake Superior, Peter Dykema and state environmental
officials walk to the spot where they have equipment that counts the numbers of coaster
brooks going up river to lay their eggs. Dykema says they counted more than 80 fish last
season. The population seems to be slowly increasing here, but the stream still isn’t
perfect. There’s too much sand and not enough gravel for laying eggs.


“Most of the sediment problem we are looking at is a creature of the last 40 or 50 years.
So if we can stop the input, I’m hoping that the river will be able to cleanse itself.


The sediment Dykema is talking about comes from the points where roads cross the river.
People and cars jar soil loose and it fills up the riverbed. This is the fish’s current
challenge. Coaster brook trout are sensitive and susceptible to pollution. Conservation
officials use brook trout as indicators of high water quality. Coaster brooks will die if
they don’t have nearly perfect conditions.


(Sound of Lake superior waves lapping on rocks.)


Few anglers alive today have seen coaster brook trout, but if they could this would be the
place. It’s where the Salmon Trout River meets Lake Superior. For a diverse group of
conservationists, this place symbolizes what people did to the land and water of the
region.


Laura Hewitt is visiting from Trout Unlimited in Wisconsin.


“This is a fish that presidents came to fish for, that Hemingway wrote about. It’s
something that captures the imagination, it touches the soul. It’s a fish that we care
very much about and think it can be sort of a rallying point for action in the basin.”


Those working to preserve the last few hundred coaster brook trout say we should feel
lucky that they’re not all gone. They say now’s the time to keep what’s left, build it up,
and use the eggs from this small population to start the fish in other streams of Lake
Superior. Then perhaps within our lifetime, our children can enjoy the fish that our great
grandfathers did, and in doing that, they’ll know the water’s clean.

Downtown Residential Development on the Rise

For decades, Americans have been fleeing the grit of city life for the serenity of suburbia. And while that trend still continues, a new pattern is emerging. The long commutes that are often part of suburban life are driving many people back to the city. The Great Lakes Radio Consortium’s Steve Frenkel reports from Chicago:
