Suburban growth typically degrades
the quality of rivers and lakes. But
developers are finding ways to protect
water quality even as they build housing
developments and malls. Stephanie Hemphill
reports on a stream in a major metropolitan
area that still has trophy-sized native
trout in it – and how people are working
together to protect the trout:

A half dozen people in waders stand nearly waist-deep in a bend of
the Vermillion River. They’re getting ready to send electric shocks
through the water.

(sound of gas motor starting)

They’re looking for trout.

They’re stunning the fish so they can catch them in nets. When they
have about ten fish of all sizes in their bucket, they pull their boat to
the side to count and measure them.

“You can see on the one he’s pulling out right now, it’s a male, it’s got
that big hook jaw on the front. 532. These are millimeters; that’s
about 21 inches. ”

Brian Nerbonne is a trout habitat specialist with the Minnesota
Department of Natural Resources, and today he’s a happy man. He’s
collecting a healthy batch of trout on this river just thirty minutes from
downtown Minneapolis. He figures the big ones they’re finding are
about six years old.

“Fish grow really fast in the Vermillion: you saw when we were
shocking there’s a lot of a other fish, suckers, creek chubs, and things
like that they can eat, they grow a lot faster eating those other fish
than if they were just eating bugs.”

Biologists regard trout as a kind of canary in the coal mine. These
trout are healthy, and that’s a sign that this river is healthy for all
kinds of animals, including people.

As you walk along the stream, you can see schools and houses and
roads literally a stone’s throw from the river. Typically, development
like this threatens the trout, because it produces warm, dirty storm
water runoff.

Twenty years ago, a local sportsmen’s group asked the state to
designate parts of the Vermillion River as a trout stream. That would
mean local governments would have to do more to protect the water
quality, and not all of them were happy with the idea.

State planner Michele Hanson had the task of coaxing local officials
to get on board.

She did that by doing what the DNR is doing today – shocking the
river to show local officials there was something there worth
protecting.

“Once everyone believed us that it’s trout stream, then we went out
and met with every community along the river, of the section that we
were going to designate as trout stream, to tell them what it would
mean to them, what changes might happen.”

It would mean every town, every township and county that the river
flowed through would have to make some changes in the way they
developed.

Now, in some sections of the river, builders must leave a buffer to
protect the stream, as much as 150-feet wide.

Also, they need to avoid increasing the amount of runoff. Rainwater
that sheets off roads and driveways and rushes directly into the river
is too warm for the trout.

Builders are learning how to get the water to soak into the ground
instead. They can build narrower streets and shorter driveways.
They can build rain gardens and other landscaping that holds the
runoff long enough that it can soak in.

The state is also building structures in the river to provide better
hiding places and spawning grounds for the trout.

It’s all aimed at holding onto a rare treasure – a healthy trout stream in
a major metropolitan area.

The Fish Are Floundering

A new study shows things are getting
worse for fish in North America. Lester
Graham reports water pollution is the problem:

The U.S. Geological Survey finds nearly twice as many kinds of fish are now listed
as imperiled today than just 20 years ago. 61 types of fish have gone extinct.

Howard Jelks is the lead author of the study.

He says the decline in fish is because most streams, rivers, and lakes are in worse
shape because of sprawling development, farmers’ chemicals, and pollution washed
off parking lots and streets.

Even if you don’t go fishing, or really even care about the fish, Jelks says there’s a
reason you should care.

“You know, at a certain point, it’s a quality of life issue. If it’s not good enough for
some of these fish, it’s probably not good enough for your kids to swim in.”

And the experts say that means we all have to think about what’s going down the
drain and what chemicals we’re putting on lawns, and on farms.

Environmental groups are

pollution from farm fields in states
that drain into the Mississippi River
and its tributaries. The pollution
contributes to a so-called ‘Dead Zone’
in the Gulf of Mexico. Chuck Quirmbach
reports:

Nine groups from states bordering the Mississippi River are calling for standards
to limit nitrogen and phosphorus pollution. The main source of the chemicals
is runoff from farms.

Attorney Betsy Lawton is with Midwest Environmental Advocates.

She says it’s been ten years since the Environmental Protection Agency said it
would make states in the Mississippi Basin protect and clean up the waters.

“EPA has long held that it would step up and take action when states failed to do.
It has set several deadlines for states to take this type of action and limit this
pollution but has let the states slide from those deadlines.”

The nitrogen and phosphorus flow down the Mississippi into the Gulf Dead Zone
– an oxygen depleted area of about 8,000 square miles – or the size of the state
of Massachusetts.

Construction Sites Mucking Up Rivers

Some home builders say the housing market
is tough enough. They don’t need environmental
regulations that make it tougher on them. But
some “green” builders say the housing industry
can improve the environment, do the right thing
for communities, and still make money. Julie Grant
reports:

Have you ever driven by a construction site and seen all that dirt? A lot of that dirt is washed off the site by
rainstorms and ends up in local creeks and rivers.

Russ Gibson is with Ohio Environmental Protection Agency.
He says that dirt kills aquatic bugs and fish.

The dirt covers up gravel bottom streams – that fills holes
where bugs want to live. If bugs can’t live it mucks up the
food chain. Gibson says fishermen know when this
happens.

“You’ll have some of the smaller fish and the bait fish, like
minnows and darters, will feed on the small bugs that live
there. If you don’t have bugs to feed the bait fish you don’t
have bait fish to feed the big fish.”

Beyond that, the silt from construction sites can also muddy
up where fish lay their eggs.

And enough construction dirt can fill a stream so much that it
can make flooding more of a problem.

So, how much dirt are we talking about?

The EPA estimates that 20 to 150 tons of soil per acre is lost
to storm water runoff from construction sites.

That means every time a new house is built, truckloads of
soil can wind up in local streams.

If a homebuilder pulled a truck up to a bridge and dumped a
load of dirt into a creek, people would scream. But because
construction site runoff is gradual and not as obvious,
builders get away with it.

Lance Schmidt is a builder. But he’s not your typical builder.
They used to call him a “tree-hugger builder.” These days
he’s seen as a trend setter.

Schmidt says nobody in the building industry is talking much
about construction silt.

“Believe me, stormwater’s not a fun issue to talk about. (laughs)”

But it’s one of the biggest pollution problems in creeks and
rivers.

Schmidt’s crew just dug a hole for the foundation of a small
house. He’s climbs up on one of four mounds of dirt. He
knows when it rains, some dirt can get washed away, and
end up in a nearby river. That’s why he puts up sediment
barriers. But most of the time no one checks to see if he
does.

“There aren’t any regulations as far as I know. I mean other
than if somebody was to complain.”

The Environmental Protection Agency in Ohio says it does
regulate construction sites. But, usually just the larger ones,
where there might be problems. The homebuilding industry
doesn’t really think it’s the problem.

Vince Squallice is director of the Ohio Homebuilders
Association.

“Construction and earth disturbing activities in construction is
not causing the siltation problem in Ohio.”

Squallice says farmers are mostly to blame for dirt runoff in
the rivers. It’s true that sediment runoff from farms is a huge
problem. But the EPA says sediment runoff rates from
construction sites are typically 10 to 20 times greater than
from farmland.

Squallice says builders already have to deal with too many
regulations such as setbacks from streams.

“Some of the regulations recommended to protect streams go
overboard in terms of environmental protection.”

Squallice says because of the housing bust, it’s a time to
help homebuilders, not enforce more environmental
regulations.

Builder Lance Schmidt says homebuilders need to look at it
a little differently. They can help solve a problem, keep
streams clean, and help cities with flooding problems.

“And that’s the avenue that I’ve decided to attack at. Rather
than attack the regulations, let’s sit back and find ways that
we can actually do this.”

Schmidt says there are lots of creative building ideas that
can reduce flooding, and improve the rivers for fish and other
wildlife. But in this competitive market, builders won’t do it
until everyone has to play by the same rules. And he
doesn’t expect that to happen without better enforcement by
regulators.

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.

Factory Farms – Water Pollution

Transcript

(sound of giant fans)


About a thousand cows are in this building, eating, lolling around, and waiting for the next round of milking.


There’s a sharp smell of manure hanging in the air. Big fans are blowing to keep the cows cool, and to keep the air circulated.


Stephan Vander Hoff runs this dairy along with his siblings. He says these big farms are good for consumers:


“We’ve got something here and we’ve been able to do it in such a way that we’re still producing at the same cost that we were fifteen years ago. It costs more now for a gallon of gas than a gallon of milk. And so, that’s something to be proud of.”


Vander Hoff’s dairy produces enough milk to fill seven tanker trucks everyday. They also produce a lot of waste. The cows in this building are penned in by metal gates. They can’t go outside. So the manure and urine that would normally pile up is washed away by water.


Tens of thousands of gallons of wastewater are sent to big lagoons outside. Eventually, the liquefied manure is spread onto nearby farm fields. It’s a challenge for these farmers to deal with these large pools of liquid manure. The farther they have to haul it, the more expensive it is for them. Almost all of them put the manure onto farm fields.


It’s good for the crops if it’s done right, but if too much manure is put on the land, it can wash into streams and creeks. In fact, this dairy has been cited by the state of Michigan for letting their manure get into nearby waterways.


(sound of roadway)


Lynn Henning keeps a close eye on Vander Hoff’s dairy.


(car door opening and closing)


She steps from her car with a digital camera, and a device that measures water quality.


(sound of crickets and walking through the brush)


She weaves her way down to the edge of this creek.


“This is the area where we got E. coli at 7.5 million.”


High E. coli levels mean the water might be polluted with dangerous pathogens. Lynn Henning is testing the creek today because she saw farmers spreading liquid manure on the fields yesterday. Henning is a farmer turned environmental activist. She works for the Sierra Club and drives all over the state taking water samples and pictures near big livestock farms.


Henning says she got involved because more of these large animal farms expanded into her community. She says when the farmers spread the liquid manure, it can make life in the country pretty difficult:


“The odor is horrendous when they’re applying –we have fly infestations–we have hydrogen sulfide in the air that nobody knows is there because you can’t always smell it. We have to live in fear that every glass of water that we drink is going to be contaminated at some point.”


Water contamination from manure is a big concern. The liquid manure can contain nasty pathogens and bacteria.


Joan Rose is a microbiologist at Michigan State University.


“If animal wastes are not treated properly and we have large concentrations of animal waste going onto land and then via rainfall or other runoff events entering into our water – there can be outbreaks associated with this practice.”


Rose tested water in this area and found high levels of cryptosporidium that likely came from cattle. Cryptosporidium is the same bug that killed people in Milwaukee back in 1993. Rose says livestock farmers need to think more about keeping these pathogens out of the water. But she says they don’t get much support from the state and researchers on how best to do that.


For now, the farmers have to come up with their own solutions.


(sound of treatment plant)


Three years ago, the state of Michigan sued Stephen Vander Hoff’s dairy for multiple waste violations. The Vander Hoff’s settled the case with the state and agreed to build a one million dollar treatment system. But Vander Hoff isn’t convinced that his dairy was at fault, and thinks that people’s concerns over his dairy are overblown:


“If we had an issue or had done something wrong the first people that want to correct it is us. We live in this area. So why would we do anything to harm it?”


Vander Hoff is upbeat about the new treatment system. He says it will save the dairy money in the long run.


The Sierra Club’s Lynn Henning says she’s skeptical of the new treatment plant. She’ll continue to take water samples and put pressure on these farms to handle their manure better. In the end, she doesn’t think these big farms have a place in agriculture. She’d rather see farms go back to the old style of dairying, where the cows are allowed to graze, and the number of animals isn’t so concentrated.


But farm researchers say because consumers demand cheap prices, these large farms are here to stay and there will be more of them. Because of this, the experts say we can expect more conflicts in rural America.

Corn Ethanol: More Water Pollution

Government-funded programs that pay for
conservation on farmland have done a lot to
improve the environment over the past twenty
years. The federal government has paid farmers
to take some cropland and set it aside to protect
waterways and wildlife habitat. In the second of
our two-part series on ethanol, Julie Grant reports
that some of that conservation is being stalled:


A good hard rain can wash a lot of valuable soil off a farm field.
John Wallbrown grows corn and soybeans on his farm. He says losing
soil is just like losing money. The soil carries with it all the
nutrients he’s put in the fields to help the crops grow, things such as
nitrogen and phosphorous. Wallbrown says he’s put in a good number of
grass waterways through the fields to help filter the water and hold on
to that soil:


“And so when you put in a grass waterway, it dramatically reduces the
amount of erosion. And it is just better for the water supply, better
for our crop. We’re keeping our soil in our field as opposed to it
getting put away.”


What Wallbrown calls nutrients in the field are considered pollution
once they wash into rivers and lakes. So Wallbrown says planting grass
near waterways is good for everyone. Except it means he’s got to use
land that otherwise could be growing crops, and that’s a loss of
income.


Wallbrown has gotten various government assistance to offset those
losses. The largest program, is called the Conservation Reserve Program, known as the
CRP for short.


John Johnson is with the US Department of Agriculture. He says when
you add up all the farms like John Wallbrown’s around the country, the
CRP is making a huge difference in reducing agricultural runoff into
waterways:


“Over 450 million tons of topsoil annually are prevented from eroding
because of CRP. We’ve got lots of really good benchmarks and measurements of
success of CRP, in both water quality, soil erosion and wildlife
habitat.”


But that set-aside land is in demand these days. There’s been a huge
call for bio-fuels to help reduce American dependence on foreign oil.
Bio-fuels are made from crops such as soybeans and corn, especially
corn. So Johnson says the government has decided to stop enrolling
new farmland into the conservation program:


“The overriding concern was that there is a need for a larger supply of
corn and soybeans and wheat production right now, so given the need for
that production, let’s just take a pause right now from enrolling large
acreage of additional farmland into the CRP.”


Corn is used to make ethanol, a fuel that’s now commonly blended with
gasoline. That’s caused corn prices to nearly double so farmers say
they’re planting 12 million acres more corn this year than last year.
That’s the most corn grown in the US in more than 50 years.


Ralph Grossi, director of the American Farmland Trust, says corn needs a
lot more nitrogen fertilizer than other crops. And when it rains,
nitrogen moves quickly from the fields to the waterways. That’s
especially true when grass strips don’t filter the runoff.


Grossi says that nitrogen drains into creeks and rivers from 36 states
into the Mississippi River and eventually to the Gulf of Mexico. There
it causes huge algae blooms that then die, sink, and the decaying
matter causes low oxygen in the water called hypoxia. That’s why the
Corn Belt has been blamed for creating a huge dead zone in the Gulf of
Mexico each year:


“If you increase corn production and don’t add the conservation practices
it will add nutrients and exacerbate problems in the gulf with hypoxia.
But it’s not just in the gulf, it’s problems for every local water
district that has to purify water for drinking and other urban
purposes. As they have to contend with more nutrients, that increases
their costs of cleaning the water.”


Grossi says the best place to clean the water is at the source. He
says that’s why the government must continue to help farmers pay for
grass waterways and buffer strips – those things prevent farm nutrients
from getting into the water in the first place. He says the need for
grass waters is even greater now that so much farmland is being planted
in corn to meet the demand for more ethanol.

Cities around the country are trying to figure out how to encourage economic growth, and protect the environment at the same time. Stephanie Hemphill reports on one case where both could be winners:


Like a lot of cities, runoff from this city’s streets – polluted with salt, oil, and fertilizer – flows into a waterway. In Duluth, Minnesota, the waterway is Lake Superior.


A local group wants to turn some vacant land near a popular downtown park into a storm water garden that would clean up runoff.


But city councilor Jim Stauber says by state law, the publicly-owned land must be used for economic development.


“We have been very, very clear, and our city attorney staff has been very clear, you can’t put it here.”


Advocates such as Jill Jacoby say that’s a narrow view of economic development.


“Tourism is economic development, and what we’re creating is recreation and tourism.”


And increasingly, experts say environmental benefit often also benefits the economy.

Fertilizer Makers Cut Back on Phosphorus

Transcript

Two major manufacturers of fertilizer are cutting the amount of phosphorus in their products by half. Fred Kight reports the move should help reduce water pollution:


Phosphorus is a major source of water pollution in many parts of the country. It can create algae blooms. When these blooms die off they rob the water of oxygen, often killing underwater plants and animals.


Scotts Miracle Gro is one of the companies cutting back on phosphorus. Rich Martinez is the chief environmental officer for Scotts. He says the problem occurs when the product doesn’t go where it’s intended:


“We did it as our part of contribution to a reduction in phosphorus losses – material moving off target that might end up in the water.”


Officials from Lebanon Seaboard say they’ll also reduce the amount of phosphorus in their fertilizers. Martinez says gardeners will probably see the new, lower phosphorus products on shelves by next spring.

Cloning Plant Species for the Future

Lots of people worry about the extinction of animal species. But plant conservationists
say plants are even more threatened than animals. People are starting to go to great
lengths to protect them. There are banks set up to save seeds and large-scale efforts to
educate people about threats to plants. Researchers, park biologists, and others have
teamed up in one state to save a type of wildflower. Julie Grant reports:


Biologist Mike Johnson is trying to walk carefully. He’s balancing a tray of plastic
containers while hiking down damp, sun-dappled cliffs. Each container holds a few starts
of northern monkshood. These wildflowers have only been found in four states.
Johnson is in Gorge Park, one of only three places in Ohio where monkshood have been
found:


“And, in Gorge Metropark they only exist in one area, and that makes them very
vulnerable to both natural and human induced impacts.”


People who walked the Gorge in the 1980s remember seeing thousands of the blue-
hooded wildflowers. But by 2000, there were only 13 of the plants left here. Johnson
says they were being killed by the salt used to melt ice and snow on a recently built
highway. People dug a ditch to divert melted salt that washed off the road. The monkshood have
done a little better since then. There’s now a stand with 190 of them, but
conservationists want to make sure this wildflower survives long term. Today Johnson is
planting new monkshood starts on the opposite side of the River, away from the
highway:


“So the goal is to establish satellite populations throughout the Gorge Metropark, so if
for some reason they were to die out in one area, they wouldn’t die out in the park
altogether.”


You might think that Johnson and other plant people could just collect seeds from the
surviving monkshood in order to grow new plants, but the director of conservation at
the Holden Arboretum says seeds aren’t reliable enough. They often don’t grow into
plants. Brian Parsons says that when the monkshood population started to decline, the
Arboretum started looking for new ways to preserve the plant’s genetic diversity:


“The only true way to capture that is to clone the plants, so we made the recommendation
to investigate cloning because scientific literature indicated that plant potentially had the
capacity to respond to that type of propogation.”


The Cincinnati Zoo plant research program specializes in plant cloning. So it cloned the
monkshood that Mike Johnson and another biologist are planting today.


Down in the gorge, they use a trowel to dig around in the rocky soil. They’re looking for
planting conditions that will give the monkshood the best chance to survive:


“Literally, that, over there is perfect. There’s not full sunlight. The trees above are
filtering out a lot of it. Just a little sunlight is getting down to the bottom and you’ve got
cool, clear springs. And even though we have all the surrounding development, there are
still springs in the gorge that are fairly uncontaminated from urban runoff and pollution.”


Water drips onto the biologists from the overhanging rock formations. They plant a
couple of monkshoods right in the crevices of the rocks. The leaves are reminiscent of a
buttercup. They are in the same family of plants. They’re not in bloom now. In the
spring, the delicate blue flowers remind some people of a religious hood. That’s how the
plant got its name.


Once Johnson puts these small monkshood starts in the soil, it’s hard to distinguish them
from the other ground-cover. That’s not a bad thing. Johnson says it’s best if people don’t
know exactly where to find the rare northern monkshood:


Grant: “You think people would poach them or something?”


Johnson: “Yeah. Yeah. It’s possible. We don’t generally try to advertise their location.
Anytime something’s rare, it’s valuable and somebody might want to take it.”


Plant specialists believe each plant species provides a purpose in nature, and might hold
some promise for pharmaceuticals or some other use. They’re just not sure yet what
people can learn from the northern monkshood. That’s why they want to make sure it
survives.
