There is a man-made canal that connects
the Mississippi River system with the Great
Lakes. The Chicago Ship and Sanitary Canal
makes shipping cargo between the waterways
possible. It also makes it possible for invasive
pests in the water to invade both systems.
The big concern right now is a big, nasty group
of fish known as Asian Carp that’s already
invaded the Mississippi and some of its
tributaries. An electric barrier has been built
in the canal to try to stop the fish from getting
into the Great Lakes. Lester Graham talked with
Jennifer Nalbone about the problem. She’s the
Director of Navigation and Invasive Species with
the environmental group Great Lakes United:

Jennifer Nalbone: They are just incredible eaters, and they get as big as 3 to 4 feet, 80 to100 pounds when mature. And they are just prolific. Some species, the females can produce over 1 million eggs in their lifetime. So the fear is, like they’ve done in the Mississippi River Basin, they’ll get so big, they’ll have no predators, they’ll eat so much food, and there’ll be so many that they’ll basically take over the ecosystem. In some areas, where they’ve invaded, upwards of 90% of the river’s biomass is carp.

Lester Graham: You’ve probably seen this fish on videos or something like that – they’re the ones that as a boat passes by, they’ll jump out of the river, and sometimes even hit the boaters.

Nalbone: I admit, the first time I saw a video of the jumping silver carp, I was so startled I laughed at it. But there’s nothing funny about 50, 60, 70 pounds of fish flying at you when you’re going 20 miles an hour. It could kill someone.

Graham: Now, there’s this electric barrier in place that actually shocks the water so the fish is discouraged from coming into the area. But now there’s concern that the fish has invaded a nearby river, the Des Planes River, that’s very close to this canal. So, why’s that a problem?

Nalbone: Our concern is with flooding. Just last year, we saw major floodwaters in the Des Planes River, where floodwaters connected the Des Planes and the Chicago Sanitary Ship Canal in streams of water several feet deep. And carp could be carried into the Chicago Sanitary Ship Canal in those floodwaters.

Graham: So, what are you proposing? How could we stop the fish from going any further?

Nalbone: Well, the long-term solution is hydrologic separation of the Mississippi River Basin and the Great Lakes Basin. Army Corps of Engineers has been authorized to study that problem, but that’s a multi-year project. Right now, what we’re concerned about are floodwaters this fall. We are pressing that the Army Corps of Engineers put in place sandbags or berms in the low points between the Des Planes and the Canal. And also fill in some of the culverts in the IMN Canal that connect to the Chicago Sanitary Ship Canal.

Graham: Now, I’ve watched this situation for years – long before the Asian Carp invaded the Mississippi River system – and I’m wondering, even if further millions of dollars are spent, to try to put up barricades or stop this fish, whether it’s simply inevitable that this fish will get into the Great Lakes.

Nalbone: Well, this is a battle against time right now. If we can block the future floodwaters from the Des Planes – which is probably our biggest hole in our defense right now – and plug the culverts in the IMN, we can buy ourselves some good time. But we won’t be out of the woods until we separate the Mississippi and the Great Lakes Basin. But we can’t let this invasion happen. It would be, perhaps, the greatest anticipated ecological tragedy of our time. So, I don’t think that inevitable is an option. We have to get it done.

Graham: Jennifer Nalbone is with the group Great Lakes United. Thanks, Jennifer.

Nalbone: Thank you, Lester.

Close Contact Endangers Dolphins

Television dolphins like Flipper
and the performing dolphins at
Sea World can trick people into
thinking it’s okay to feed and
swim with wild dolphins. But
Rebecca Williams reports dolphin
researchers say our behavior can
hurt and even kill dolphins:

(sound of a shorebird crying out)

Fort Myers beach is packed with tourists. I meet a guy named Justin who’s here in Florida from Cleveland. He’s already gotten close to wild dolphins.

“We were out here swimming and dolphins got within a foot of us. It was amazing. I’ve never seen that.”

In this case, he wasn’t doing anything wrong – because the dolphins came up to him. But swimming with wild dolphins can actually be considered harassment if you approach them or touch them.

That’s bad for the dolphins because it can change their behavior. It can disturb their feeding and resting behavior. And it can separate dolphins from their babies.

So it’s illegal to swim with or harass dolphins. You can get fined and even end up with some jail time. And that’s just the beginning of the dolphins’ problems.

Dolphin encounters are getting more common in Florida and Hawaii and a lot of other places. There’ve been more tourists and more boaters in the water… and more commercial operations that promise you’ll get a chance to feed or swim with dolphins.

As cool as it might be for us, it’s actually terrible for dolphins. When people feed them they can get addicted to human handouts.

Cartoon Dolphin PSA: “For me it started with one hit of sardines, oh sardines… that’s where I learned to beg. It was easy to score free fish… with this dolphin smile? Yeah it’s illegal but no one cares…”

That’s a cartoon dolphin in rehab with a bear, a raccoon and a seagull. All those other animals we’ve gotten into some bad habits with.

It’s a message put out by the Mote Marine Laboratory in Sarasota.

(sound of dolphin playing in tank at the Marine Lab)

Randall Wells is the head of dolphin research at the lab. He’s spent almost four decades studying dolphins.

He says, in recent years, there’s been a dramatic increase in the number of dolphins getting into trouble with people. More people feeding them and getting too close to dolphins in their boats.

“And we’ve seen an increase in mortality from these kinds of interactions – from people luring animals in towards boats, in towards fishing gear. Dolphins have begun to take bait from lines getting tackle including hooks and lures in their bodies and killing them or seriously injuring them.”

He says, if you feed a dolphin, it’ll often start begging for food from people. And that dolphin will teach its babies or other dolphins to beg.

Sometimes they’ll even eat things that aren’t food. One dead dolphin had a plastic snake in its stomach.

If dolphins get closer to boats, they can get snared in fishing line. It can slice through their flippers. Once, Randall Wells rescued a dolphin that had a Speedo on its head. And because it couldn’t shake it off, the suit was cutting into the dolphin’s flesh.

Wells and his team have been doing a lot of outreach to stop people from getting too close to dolphins. And he says most of the time, it works.

“But there’s still a half percent of people that, by their own admission, insist on interacting with these animals – feeding them and approaching them in ways that are illegal, just because they can and they’ve never seen the negative consequences of doing that.”

If you want to go on one of those dolphin viewing tours, there are some ways to make sure the tour operator’s not adding to the problem.

Stacey Horstman helps run a program called Dolphin Smart. It certifies dolphin tours as responsible.

Right now there are only four businesses in Key West and one in Alabama that’ve gotten certified. But, she says, if you’re in a place without Dolphin Smart tours, you can still ask questions.

“Just to make sure that feeding is not being promoted in any way, that they’re promoting responsible viewing from a distance.”

That means staying at least 50 yards away from dolphins.

She says any ad that shows people swimming with dolphins or handing them fish is usually a sign of an irresponsible business. So those are ones to stay away from.

Dolphins might look cute and friendly, but Horstman says they are wild animals and they need their space.

Osprey Nest Near Fish Hatchery

Ospreys are birds of prey that eat fish. Todd Melby tells us
about a pair of osprey that tried to nest near a fish hatchery:

The osprey is a raptor that scoops fish out of rivers and lakes.

So when a pair of osprey decided to mate near a DNR fish hatchery south of
Minneapolis, biologists were delighted and worried.

Ospreys rarely nest so far south. So that was good news. What worried biologists was
whether the birds would eat the fish. Biologists decided these fish were too small.

Another worry was the ospreys’ choice of a nesting site. In this case, the birds picked an
electrical power pole.

Lisa Gelvin-Innvaer is with the Minnesota DNR.

“They like high areas. Places that have room for them to put their nest. Transmission
poles often provide that.”

Biologists decided that was a bad idea, so they’ve built a tall nesting platform near the
power pole.

“We’re hopeful with the new nesting platform, that they’ll come back and attempt to nest
again.”

Canada’s Blue Flag Beaches

Beaches on the Great Lakes have

Beaches on the Great Lakes have
been closed a lot this summer because of
pollution. But instead of raising the
white flag of surrender, in Canada, they’re
starting to raise a blue flag. Julie Grant
reports the Blue Flag Programme certifies
a beach is safe:

(sound of beach)

It’s a clear, cool summer morning by Lake Ontario. Some
people are playing volleyball, others are walking along the
boardwalk at Woodbine beach, on the east side of Toronto.
Nobody is swimming in the lake.

Beach person 1: “No I don’t swim here.”

Beach person 2: “I grew up here, and I’ve never actually
swam in Lake Ontario. Sometimes they were closed and it
was always off and on, so it never seemed like a good thing
to do.”

Beach Person 3: “It’s gross, man. It’s pretty nasty. One
time I found a couple of Band Aids. After that, I was like, ‘I’m
not going back in this water.’”

City leaders say those views are outdated.

Lou DiGeranimo is Toronto’s general manager of water.
He’s in charge of everything from drinking water to sewers
and storm water runoff.

DiGeranimo says the Lake’s bad reputation lingers
from the time when Toronto was a major port for lumber, for
shipbuilding, and for foundries.

“When you talk to certain people in the city, they remember
the old industrial heart of our city and they think that Lake
Ontario is polluted and you shouldn’t swim in it. Well we beg
to differ. You can swim in it and our water quality is actually
quite good.”

DiGeranimo is trying to change the public image of Lake
Ontario one beach at a time. So far he’s been able to get six
Toronto beaches certified as safe by an international
program called Blue Flag. DiGeranimo says the blue flag
shows that someone besides the city is checking up on the
beaches.

“There’s an external group, Environmental Defense, that
actually, we work with. And they themselves are part of a
larger international group who come round and audit to
make sure that we are following the program accordingly.”

Thousands of beaches in The Caribbean, Europe and South
Africa fly blue flags. Toronto has some of the first beaches
in Canada to be certified by the program. The city has to
test water quality every day. It also has to provide
lifeguards, recycling containers, and environmental
education programs.

But water quality is usually the biggest obstacle for beaches
trying to get a certification.

(sound of beach)

A blue flag waves in the wind at Toronto’s Woodbine beach.
But not without considerable cost. The sewer used to
overflow regularly here into Lake Ontario. The city built
underground retention tanks to store sewage overflow until it
could be sent to a treatment plant.

But multi-million dollar sewer fixes usually are not possible
for many cities.

So DiGeranimo says people also need to take action at
home. Toronto has been trying to educate people to be
careful what they wash down the drain. And DiGeranimo
says Toronto banned the use of some lawn chemicals
because they were polluting the Lake.

“If I took a bag of chemicals and then just dumped it in the
river, I could charge you for impairing the water quality. But
if you dumped it on your lawn first, and then it ended up in
the creek, that would be okay. So in the city we passed a
bylaw that restricted the use of certain chemicals.”

That kind of ban would be a tough sell in most U.S. cities. It
wasn’t easy in Toronto either.

But Jody Fry says it’s helped the city earn Blue Flags at
many beaches. Fry is Canada’s national Blue Flag program
coordinator. She says people on all shores are starting to do
the work to certify their beaches.

“It raises awareness both at the beach and throughout the
community of what actions people can take to help improve
the water quality. Which, I think, people are looking for,
because they want to help contribute to protecting the
environment.”

The city of Toronto hopes to raise Blue Flags at five more
beaches soon. For now, they want to spread the word – if
you see a Blue Flag flying at the beach, it’s a signal that you
can trust that the water is clean for swimming.

Report: Beach Closings Still High

The number of days beaches were
closed due to pollution last year was
the second highest on record. Mark Brush
reports, that’s according to a new report
by an environmental group:

The National Resources Defense Council says beaches across the country were closed to
swimmers for more than 22,000 days last year.

Sometimes the beaches were closed when sewer plants would overflow.

Nancy Stoner is with the Natural Resources Defense Council.

She says most of the time beaches were closed after a big rainstorm

That’s because rain washes pollution into the water.

“I’m more cautious now after swimming after a heavy rainfall. And the other thing about
it is that the ocean beaches in general tend to be cleaner than beaches that are in bays
and sounds and other protected areas, so it makes me want to go to the ocean.”

Ocean waves tend to wash away the pollution a lot faster.

Beach closings along the Great Lakes were twice as high as the national average.

Paying for Ponds to Stem Farm Runoff

Since the dust bowl days of the 1930s Depression, the government has been working with farmers to reduce erosion. Today, soil conservation is better. But fields still lose a lot of topsoil because not all farmers use the best conservation methods. Dirt is washed away by rain. That silt clogs up streams, rivers and lakes.

Since the dust bowl days of the 1930s Depression, the government has been working with
farmers to reduce erosion. Today, soil conservation is better. But fields still lose a lot of
topsoil because not all farmers use the best conservation methods. Dirt is washed away
by rain. That silt clogs up streams, rivers and lakes. But one region is trying to intercept
the silt before it gets to the river system. The GLRC’s Lester Graham reports:


Farm fields in all or part of 38 states drain into the Mississippi River. Some of the
tributaries of the Mississippi are so silted that dredges have to operate around the clock to keep river
shipping lanes open.


The Sangamon River in central Illinois is not big enough for shipping cargo, but it does
run into the man-made Decatur Lake. The city of Decatur gets its water from that lake
and often has to dredge it to keep the water inlets from clogging up.


Keith Alexander is the Director of Water Management for the city of Decatur, Illinois.
He says a little soil erosion on enough farms adds up:


“And the drainage area that runs into the lake is 925 square miles of some of the world’s
best topsoil. We have literally a half-a-million acres of corn and soybean fields that flow
into our lake that we use for drinking water purposes.”


Not only does the silt clog the lake, it also carries fertilizers and pesticides with it,
polluting the lake. The city has offered farmers financial incentives to reduce soil
erosion. But it hasn’t gotten enough participation from farmers to solve the problem. So,
the City of Decatur decided to try another approach. They would offer money to landowners to build ponds. Those ponds would be located in key drainage areas next
to farm fields.


Shannon Allen is a watershed specialist with the Macon County Soil and Water
Conservation District. He says it turned out to be a pretty popular program:


“The landowners wanted it for recreational purposes, obviously fish, maybe swimming
or whatever. We’re putting them in so we can collect sediment from the farm fields
above them so they don’t go into the river system.”


Shannon Allen says the ponds work a lot better at keeping silt out of creeks and rivers and lakes
than other methods to reduce erosion.


“Basically ponds collect 90% of the silt. And, so anytime you can put up a pond, you’re
doing better than a grassed waterway or a terrace that don’t reduce sediment loads by that
much.”


The city offers up to 5,000 dollars to landowners, but that’s well short of the actual cost. A typical pond
can cost 20 to 25,000 dollars to build. But landowners have been taking the city’s offer.


Alan Roberson owns a few acres at the bottom of a sloping corn field. About 42 acres
drains onto his property and then into a creek. He says when he moved there, there was
just a big ditch where stormwater from the neighboring farm fields washed a bigger and
bigger gully, carrying sediment to the creek:


“There was places eight, ten feet deep. We’ve lived here almost 20 years and it just kept
getting deeper as it went along. I hated to even come down here and look at it because it
was getting so bad. So, I’m glad that program came along to take care of it. As you can
see, it’s not doing that anymore.”


Roberson took advantage of the city’s pond program. Where the gully used to be, a carpet
of green lawn now borders a picturesque little pond.


Alan Roberson says the pond has a pipe in the bottom of it, kind of like a bathtub plug. It
was part of the design required to get the matching funds from the city. When the pond
fills up with silt, Roberson will be able to drain it and dig out the soil:


(Sound of water trickling)


“See this valve down here? You can actually pull that up. It could very well be 20 years
from now they’ll get enough silt in here where a person will have to bring it down. But
like I said, it’s designed to do that.”


That silt is some of the richest dirt in the corn belt and could be sold back to farmers or
used for gardens or flower beds. The landowner will have to pay the cost of digging it
out, but it’s that much more silt that won’t have to be dredged from the lakes or the rivers
that feed them, where people get their public water supply.

Ten Threats: Botulism Kills Beach Birds

  • Interns for Presque Isle State Park in Erie, Pennsylvania walk along a Lake Erie beach picking up dead birds. (Photo by Lester Graham)

Researchers are beginning to understand what’s killing thousands of
Great Lakes shorebirds. It might be part of a larger problem indirectly
caused by humans. The Great Lakes Radio Consortium’s Lester Graham
reports:

Transcript

We’ve been bringing you reports from the series, ‘Ten Threats to the Great Lakes’ which is now looking at the threat to beaches. Our guide through the series is Lester Graham. He reports that scientists are beginning to understand what’s killing thousands of Great Lakes shorebirds. It might be part of a larger problem indirectly caused by humans.


Researchers are beginning to understand what’s killing thousands of
Great Lakes shorebirds. It might be part of a larger problem indirectly
caused by humans. The Great Lakes Radio Consortium’s Lester Graham
reports:


Along parts of Lake Erie, Lake Ontario, and Lake Huron, large numbers
of dead birds and fish are washing up on shore. If they’re left there, the
disease that killed them can be passed on to other wildlife. That’s why
park officials such as Mike Mumau at Presque Isle State Park at Erie,
Pennsylvania ask their staff to watch out for the dead carcasses.


“Our interns do a great job. They’re the eyes of the staff that are out. So,
there’s probably three to four days a week that they’re out on the
beaches, checking to see if they have anything.”


Since 1998, untold numbers of fish and sometimes hundreds of dead
birds a year have washed up on just these eight miles of Lake Erie beach.


Eventually, researchers figured out the problem: type “E” botulism. It
slowly paralyzes the birds until the respiratory system shuts down. Most
of them don’t make it that long. They get so weak they can’t hold their
heads up out of the water and they drown.


(Sounds of walking and shovel)


Leslie Jones and her fellow interns are headed out to an area to pick up
some dead seagulls on the beach.


“When we’re out here doing migratory bird studies, we might see some
and then we pick them up as soon as possible. A lot of times, we get
radioed from different people like lifeguards and they have us come out
and pick them up so that the disease doesn’t spread throughout the rest of
the ecosystem.”


They find five dead birds rotting on the beach. They bury the maggots
because they could carry the botulism toxin and other birds might eat the
maggots. They shovel the bird carcass into a black plastic garbage bag.


“If they’re very fresh, this one, obviously not very fresh, but, if we get a
fresh one, we actually freeze them and they’re sent off to be tested
botulism, but, something like this we’ll just bag up until we can get them
incinerated to get rid of all the disease.”


The fresh carcasses are shipped to the National Wildlife Health Center in
Madison, Wisconsin.


There, Grace McLaughlin is among the researchers who are beginning to
put the puzzle together.

Here’s what they think is happening. The invasive species zebra mussels
and quagga mussels create huge mussel beds that begin a complicated
biological phenomenon. Organic matter collects there, and then decays. It
lowers the oxygen level in the immediate area of the mussel beds. Type
“E” botulism spores occur naturally, but when the oxygen level goes
down, they begin reproducing like crazy. The waste they produce is the
toxin.


“That toxin will accumulate in the organic matter as well as in the water
in the immediate vicinity of the mussel beds. As the mussels do their
filter feeding, they will accumulate the toxin in their tissue. They are not
susceptible to the toxin. However, when the fish start coming down
there and eating the mussels, they become intoxicated, lose their ability
to swim properly and become easy prey for the birds that come in.”


The fish that feeds on the mussels the most is another invasive species,
the round goby. Researchers made the connection when they noticed the
botulism started being a problem shortly after round gobies arrived in big
numbers.


The type “E” botulism toxin has killed tens-of-thousands of birds such as
cormorants, terns, loons, ducks, and seagulls.


Back at Presque Isle State Park, Mike Mumau says it’s terrible to see so
many birds die.


“We just do our best on our end to stop the botulism cycle. When we
can, provide samples, and also, keep it a positive recreational experience
for all our visitors. They don’t want to see birds decomposing and
rotting out on the beaches, so we’re pretty diligent with that.”


Researchers say that’s about the best that can be done. Since ocean-
going vessels brought zebra mussels, quagga mussels, and round gobies
to the Great Lakes, all three of the invasive species have flourished. It
will likely be a long time before we’ll ever begin to understand the full
extent of the damage to the native wildlife of the lakes.

Researchers Call for Hydrilla Hunt

Great Lakes researchers are looking for volunteers to help search for an invasive aquatic
plant that can choke out native vegetation, and make it tough to fish or boat. The Great
Lakes Radio Consortium’s Erin Toner reports:


Universities and Sea Grant programs throughout the region want people to search bays
and inland lakes for a non-native plant called hydrilla. It’s been found in waterways in
southern states and on the East Coast. Researchers want to make sure hydrilla doesn’t
gain a foothold in the Great Lakes.


Howard Wandell is an inland lakes specialist at Michigan State University. He says
hydrilla forms a net of vines at the surface of the water.


“It’s difficult to motorboat through and obviously trying to cast fishing lures through it is
very difficult if not impossible. And of course then just the idea of even trying to swim
in it, people are very repulsed by the idea of trying to go out and try to recreate in this
tangled mass of vegetation.”


Wandell says hydrilla also blocks sunlight, which can kill native water plants.

Tug-Of-War Over Great Lakes Seawall

Cities along the Great Lakes often depend on sea walls
to keep the crashing waves from eroding the shoreline. Some of
those walls have been around for close to a century. One city wants
to rebuild its protective walls. But the neighborhood near one popular
section is not happy about it.


They say the huge limestone blocks give
the area character. They don’t want concrete to replace any of it. But
the structure is deteriorating, and the city and Army Corps of Engineers
want to shore it up. The plan for repairing the seawall is igniting an
age-old debate between historic preservation and shoreline protection…
and it’s got an entire neighborhood ready to fight. The Great Lakes Radio
Consortium’s Lynette Kalsnes has more:


(Sound of water)


Jack Reed stands on the edge of the huge limestone rocks that make up the seawall, drying himself off. He just swam a mile along the shore of Lake Michigan. He drapes a big flannel sheet over his head that he’s fashioned into a makeshift changing tent, and modestly gets out of his swimsuit.


The 67-year-old has been swimming off this rocky peninsula that juts into Lake Michigan for forty years now. He says the trees and the giant limestone rocks made him appreciate nature and realize how much he needs a break from the city.


“I sort of hate to leave and go back to the grind, ’cause when you’re out here, you can relax and look at the sky and get in the water and watch the birds and the clouds go by. It’s like a vacation trip, just as long as you have time for.”


The place where Reed comes to swim and relax is called Promontory Point. The point is lined with large limestone blocks that stretch along the water like a chunky, irregular staircase.
People come here to swim, fish and bicycle. They have picnics, walk their dogs and throw Frisbees.


The city and Army Corps want to replace a lot of the limestone with concrete. They say the limestone seawall is getting weak. They just overcame an important obstacle by winning approval for their concept from the Illinois Historic Preservation Agency which recognizes the limestone wall as a historic part of Chicago. Jack Reed says replacing the limestone with concrete would make the Point seem sterile.


“The thing about concrete is it’s artificial. It’s manmade. We spend most of our lives inside buildings and buses and subway tunnels; that’s all manmade.”


Reed says he comes here to escape what he calls the “concrete jungle” of the city. He says the limestone makes a soft, naturalistic transition between land and water. But the lakeshore isn’t as natural as it looks.


Less than a century ago, this whole area was part of the lake. The point was created by dumping debris into the lake in the 1920s. Workers built the limestone seawalls on top of wood shorings. Now the wood is rotting, and the rocks are shifting. The city and the Army Corps say that’s dangerous for people and for the shoreline.


And the Illinois Historic Preservation Agency says there needs to be balance between safety and historic preservation and making the shoreline accessible to people with disabilities. David Blanchette is with the state agency. He says the wall has to be reconstructed to stabilize the shoreline.


“Our job is to make sure that this historical resource, which was built for a specific purpose quite some time ago, preserves as much hisotric character as possible, but still allows it to function for its intended use.”


The work at Promontory Point is part of a 300-million dollar project to replace miles of old limestone revetments along the city’s lakeshore, but the point has caused a snag in the plan. Community members and preservationists have stalled the work at Promontory Point for years now.


The Landmarks Preservation Council of Illinois put the point on its list of ten most endangered historic places in the state, putting it at odds with the Historic Preservation agency.
And Council president David Bahlman says it’s one of the few spots left where the lakeshore hasn’t been hardened with concrete.


“Let’s say it’s an unacceptable compromise that moves closer to ensuring that two-thirds of the point is going to be destroyed.”


Most critics acknowledge something needs to be done to protect the shore from erosion. But they say it’s entirely possible to come up with a plan that preserves limestone on the entire seawall, not just part of it. A community group is now lobbying the U.S. Senate for legislation to prevent funding for construction unless the limestone wall is preserved much as it is. A similar measure has already passed the U.S. House.

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.


For the GLRC, I’m Michael Leland.
