The Environmental Protection Agency has
a new water saving program called Water
Sense. It’s similar to the Energy Star label
for electronics. To get the Water Sense
program’s endorsement, toilets must use less
water. But, people have been complaining
about the old style low-flow toilets since they
were first required in the mid-1990s. Lester
Graham reports on what’s changed since then:

The problem with those old low-flow toilets is the companies didn’t really re-design them – they just made the tank smaller. Some of them just didn’t do the job.

Hugh Maquire has one in his home. He’s had a bad experience with his.

Maquire: “I had to flush my low-flow toilet six or seven times. What is that saving you?”

Graham: “ Doesn’t save you much water that way does it?”

Maquire Doesn’t save you much water at all. Plus it’s annoying. It’s embarrassing, ‘cause everybody’s hearing you flush the toilet six or seven times, wondering what the heck’s going on in there.”

So, we asked Matt Grocoff with Greenovation TV to set up a demonstration for us. Behind the Bgreen Retail Store in Ann Arbor, Michigan three different models of these new Water Sense low flow toilets are set up on five-gallon buckets so we can see what gets flushed… and what comes out.

Grocoff: “I always joke there were three things that set back the environmental movement: there was the original low-flow shower head, the original low-flush toilet and Jimmy Carter’s sweater. ‘Cause what that said to everybody was ‘You’re going to pay more for it; it was going to be less comfortable and you were going to have to sacrifice and it wasn’t going to perform as well.’ And with these new generations of redesigned toilets, you’re getting a higher quality product than even the existing one-point-six gallon or even a three gallon per flush toilet”

Graham: “Let’s see it.”

These toilets all have dual flush capabilities. A full flush is 1.28 gallons. A half flush – just 0.8. To prove how well they work, he’s just using the point-eight gallon flush. Matt’s got tennis balls, potatoes, and little rubber duckies.

Grocoff: “We got three duckies.” (flush sound)

Graham: “ Well, that seemed to work. No duckies. What’d you think of that, Hugh?”

Maquire: “I felt sorry for that ducky, but it was a great demonstration.”

And, again, that was the half-flush at 0.8 gallons, half of what the old low-flow standard was. Matt upped the ante.

Grocoff: “Two tennis balls and two potatoes. This is going to be the real challenge.” (flush sound)

Then more potatoes.
(flush)

And more duckies.
(flush)

Now, Matt’s demonstration is hardly scientific, but of the three brands we tested – a Kohler, a Toto and a Coroma – it appeared to me the Coroma worked best, at flushing duckies and potatoes anyway.

Rudy Wilfong is a dealer for Coroma. The toilet is made in Australia. He says Australia has had one-gallon-per-flush restrictions for 30 years, so they’ve designed them to work.

Wilfong: “And they don’t plug. They flush better than the 1.6 gallon toilets with half the water.”

And compared to the old low-flow toilets, you can expect to save about 1,000 gallons, per person, per year. They do cost more, but the pay back compared to a regular low-flow is about 2 to 2.5 years. If you’ve got one of those three-gallon-per-flush models, or even an old 6 gallon model, your payback will be a lot faster.

Graham: “Alright, Matt, I’m going to give you one more chance to impress me. What have you got here?”

Grocoff: “Alright. So, here we’ve got a full t-shirt. (flush) Very nice.”

Maquire: “Hey, Matt. I had a black t-shirt. Do you see it anywhere?” (laugh)

Graham: “Well, this was pretty impressive. Where can I get some more information about this?”

Grocoff: “Of course, you can go to Greenovation-dot-TV and you can see a video and some photographs of some of these toilets.”

Graham: “ Alright. Matt Grocoff of Greenovation-dot-TV. Thanks very much.”

Grocoff: “Alright. Thanks, Lester.”

It’s estimated, every year, somewhere

of old asphalt shingles end up in landfills.
Some states are short on landfill space.
Lester Graham reports, they’re now
encouraging grinding up and recycling
the old shingles:

Two-thirds of American homes have asphalt shingle roofs. They last twelve to twenty years before they need to be replaced.

Since most of the material in asphalt shingles is the same stuff used in asphalt pavement, that’s where they’re going.

(sound of machinery)

New businesses are popping up across the nation that take the shingles.

Chris Edwards is co-owner of Ideal Recycling in Southfield, Michigan. He says roofers can dump old shingles at his place cheaper than taking it to the landfill.

“And then they can also sell it to their customers that they are recycling and it’s green. So it does help the contractors quite a bit.”

Several states are studying how the material holds up for asphalt roads, but for now most of the singles are mixed in asphalt used for parking lots.

Businesses keep track of the supply-
chain, but no one really keeps track
of trash in the same way. Lester
Graham reports some researchers
think there’s something to learn
from what we throw away:

MIT researchers are going to keep track of some trash, using smart tags – tiny electronic tags. They’ll tag thousands of piece of trash, like plastic bottles. Then they’ll track them online in real time.

Assaf Biderman is with the MIT SENSE-able City Lab. He says already the public seems interested, but he hopes some other people follow along: big city decision-makers and waste disposal companies.

Biderman: “Who could benefit greatly from a better understanding of how garbage moves through the system with the idea of making their processes as good as possible.”

Graham: “Save some fuel, maybe?”

Biderman: “Save some fuel, you know, be better to the environment. I think everybody can benefit.”

Exhibits in New York and Seattle open this week, but starting tomorrow, anyone can follow the trail of trash online at MIT’s trashtrack website.

Company Trash, Classroom Treasures

Furniture stores and architectural

pile up. Usually, they get thrown in
the trash. But, in some cities, they
are starting to make unused design
samples available to artists and art
teachers. Julie Grant has more:

(sound of Anita looking thru boxes)

Anita Gardner is rummaging through boxes of old tile samples. They’re still attached to those three-fold sample books you’d see at a design store. But she’s imagining what else the kids at her community center might make with them.

“You have to see it first, sometimes. Sometimes it doesn’t come. It comes later and then you go, ‘we can do this and we can do that.’”

Gardner is at a special event called ZeroLandfill. Furniture stores, architects and design centers can drop off unwanted materials, and people like Gardner can take whatever they want – for free.

“This has been a godsend to us, because we really don’t have a lot of money to spend on arts and crafts.”

Last year, she found a lot of unused fabric – so she taught the kids at her center to sew quilts.

“And a lot of children in our community have never even threaded a needle. Now they’re learning to use sewing machines. They’re learning to piece all types of fabric together. They’re learning patterns and designs. They have no idea, they’re actually learning math.”

And in inner city neighborhoods, where kids can go to bed cold in the winter, Gardner is especially pleased that she’s started a quilt-making trend. It also warms the hearts of the folks who organize ZeroLandfill.

David Fox helps to run these events in Cleveland.

“A lot of samples end up just being discontinued and then, where does this all go? And it ends up being thrown out a lot of time. Or – they just have so much stuff they just keep hoarding and hoarding and hoarding.”

About five years ago, some folks at architecture and design firms around Cleveland, as well as a carpet company, all started talking about what to do with their unwanted material. They were spending a lot of money to send it to the landfill. So they held a one-day drop-off for companies to recycle it.

Fox says they soon realized their trash might be treasure to artists and art teachers.

“It was a program that started as a one-day thing. Firms were able to come and drop stuff off. But it has turned into a yearly process and now it’s even gone to other cities.”

Fox says they’ve already saved more than 100 tons of material from going to the landfill.

Arts and crafts teacher Anita Gardner says it’s also provided innumerable lessons for kids and teenagers at her community center.

“They see now that anything can be art. Anything can be a craft. And it doesn’t have to cost a lot to be beautiful.”

ZeroLandfill has been training architecture and design firms how to organize these events regularly. They’re now held annually in cities around Ohio – and new ZeroLandfills are being held in Minneapolis, Louisville and Boston this year.

Federal and state governments have cut
back on monitoring some big sources of
pollution, and small sources are rarely
monitored. Lester Graham reports it’s a
problem that’s even tougher when state
budgets are cut:

Industry does not pollute like it did in the 1960s or 70s. Today, regulators monitor most of those big factories.

Tom Lyon is the Director of the Erb Institute for Global Sustainable Enterprise at the University of Michigan.

“Big smokestack industries we have a fairly good eye on, but there are a lot of areas that we still don’t have a good handle on.”

Like small businesses which collectively can release a lot of toxins, and farms that use pesticides and fertilizers on millions acres.

Jennifer Sass is a Scientist with the Natural Resources Defense Council. She says, under the Bush Administration, pollution monitoring of big industry was cut back. Sass says that monitoring needs to be restored and expanded to smaller sources.

“If we quit our monitoring programs, then we don’t really know. It’s a lot like putting our head in the sand.”

But many state agencies say they don’t have the resources to keep track of all those sources of pollution.

As governments tighten their belts,
it’s getting harder for them to pay
scientists to monitor the health of
the nation’s ecosystems. So increasingly,
they’re turning to citizens who do
that kind of work for free. Ann Dornfeld
reports on the growing influence of these
“citizen scientists”:

It’s the kind of cloudy, wet day that most people spend indoors. But the cold and wet doesn’t matter as much when you’re planning to spend your day at the bottom of a Puget Sound fjord.

(sound of divers splashing into water)

About 75 miles from Seattle, these scuba divers are conducting volunteer surveys for REEF, an organization that monitors fish populations around the world. The data help researchers understand where fish live, and in what kind of numbers. It’s the kind of information governments need to understand how fishing and pollution are affecting waterways.

Back on the boat, surveyor Janna Nichols has just emerged from the 48-degree water. She pulls out her survey and goes down the list marking off what she’s just seen.

“Sunflower stars, definitely, many of those – saw a lot of those around. No sand dollars, no sea urchins. Ah! Ooh! Ah! Here’s an exciting one! I saw a giant nudibranch! A very small giant nudibranch. But those are very cool to see – a treat!”

Identifying fish can be tricky, because the same species can have different coloration depending on its age, gender, or even time of the year.

“Black-eyed gobies were everywhere. I would say under a hundred of them. And – they were mating! Because I don’t know if you noticed, they had black pelvic fins. And they kind of hover around and say “Hey, baby baby, look at me!”

As much fun as these “citizen scientists” have, professional scientists take the data these divers collect seriously. Last summer volunteer surveyor David Jennings went diving in Washington’s Olympic National Park Marine Sanctuary. He was excited to see the colorful tiger and china rockfish he’d heard were abundant at the park. But when he got there, he only saw a couple. So he looked at the past six years of REEF survey data to see how the rockfish populations had changed.

“One of the best sources was someone that wrote up a diving experience he had in 2002 where he saw dozens of tigers and many chinas. Whereas I in a week of diving saw two tigers and just three chinas. so it was a very big contrast to what people saw in the past.”

Jennings took the data to the Washington State Department of Fish and Wildlife. That’s the agency that decides fishing limits. Greg Bargmann is a department fisheries biologist who’s working on next year’s catch limits for rockfish. He says even though the REEF divers aren’t as highly-trained as the state biologists, the data they collect are more current and cover a wider area.

“The REEF survey shows a very dramatic decrease in abundance over the last five years. Our state surveys don’t show that, but we have a lot of imprecision in our surveys so we’re relying on the REEF surveys to look for changes in population.”

That’s because the state can’t afford to send its biologists out as often or to as many sites as the volunteers dive.

“We really appreciate the interest of our citizens to spend time going out there and using their own transportation costs and their own equipment to go out and collect data, and to listen to us and collect things that are not easy to do sometimes.”

You don’t have to dive to be a citizen scientist. In Ohio, citizens track everything from salamanders to spiders. In California, tighter budgets mean more poaching – and not enough game wardens. So states are training volunteers to do more work. And across the country, the Environmental Protection Agency relies on citizens to monitor water quality in lakes and streams.

Bargmann says while governments rely on citizen scientists more during budget crunches, he sees programs like these becoming increasingly important for keeping track of the health of the environment.

Stimulus Funds for Home Weatherization

The government stimulus package included billions of new dollars for home weatherization programs. The money is used to help low income folks make their homes more energy efficient. But some critics say it’s not a good use of federal tax dollars. Julie Grant reports:

Chris Graham spends his days checking the energy efficiency of people’s homes.

Today he’s at Sandra Richards’ in Mogodore, Ohio.

Graham: “Hi Sandra.”

Sandra: “How are ya?”

Graham: “Wonderful. And you?”

Sandra: “Better.”

Graham: “Better?”

Sandra is 55. Her house is clean and neat. She was a nurse for many years, but today she’s sitting on the couch, watching TV. A broken foot spiraled into problems with her knee and hip – and other health problems.

“I mean I’ve just had so many things go on in such a little time. I was working 12 hour days, and one month later, I couldn’t work at all.”

Sandra qualified for the home weatherization program because she doesn’t have much in the way of income anymore.

Chris Graham says he’s been to a lot of homes where people are far worse off. They can’t get around, they don’t have money coming in, and their houses get cold in the winter.

Graham heads to the basement.

“The first thing we have to make sure is that the heating unit is not in terrible, dilapidated shape. And that it does not have more than a specified amount of carbon monoxide in the flu gasses.”

He turns on the furnace and sticks a probe into the flu pipe.

(sound of a tester)

Grant: “Looks like a receipt came out.”

Graham: “It kind of is. It tells you exactly what was going on there.”

Looks like Sandra’s furnace is running pretty well. 81% efficiency.

But Graham sees evidence of carbon monoxide on her old water heater.

“It’s 17 years old and it just plain needs changed. It’s got burnt, scorch all over it. So we’re gonna do that.”

That could cost more than $1,000.

But the home weatherization program can afford it these days. The stimulus packaged included $5-billion for this kind of work – compared with less than a quarter of a billion dollars last year. The new money has to be spent within two years.

And some people think that’s just too much money – too fast. Leslie Paige is with a taxpayer watchdog group called Citizens Against Government Waste.

“There’s always a lot of waste in government spending anyway, but when you spend it quickly and there’s very little oversight, that’s almost a prescription for seeing a lot of that money go for waste and fraud and losing to abuse.”

That kind of criticism is shocking to David Shea. He’s director the Community Action Council of Portage County, Ohio – the organization that hires inspector Chris Graham.
The weatherization program has been around since 1976 and Shea says they have to report their spending in about a hundred different ways.

“It’s not like money is being thrown out at agencies and just say, ‘oh go out and do it.’ There are volumes and volumes of written regulations that have been around for a long time. We do so much sophisticated reporting; they know how every dollar is being spent. Always. Always.”

Shea’s office used to have one crew out weatherizing homes around the county. Since the stimulus money’s come in, he’s hired a second crew. But there are so many people wanting their services, the waiting list is still years long.

(sound of a fan)

Back at Sandra Richards’ house, inspector Chris Graham has sized a big fan into the front door. He’s depressurizing the house – so he can see where air is escaping. Graham says she’s going to need some doors sealed and new insulation in the attic.

He says Sandra will feel more comfortable, so she won’t need to turn up the heat in the winter. That means she’ll save on energy costs, and will use less fossil fuels.

That’s the whole idea of this project – to use less energy in the future, and to help millions of families that couldn’t afford to improve things on their own.

California is putting together
a huge green jobs training program.
Lester Graham reports it will mean
thousands of workers trained for a
growing part of the economy:

Last week, lost in the news of wildfires and state budget problems, California Governor Arnold Schwarzenegger announced the biggest state-funded green jobs training program in the nation. California is leveraging federal stimulus dollars with state money and public-private partnership matching funds.

“This $75-million program will train more than 20,000 workers for clean and green jobs in the future.”

Green jobs – such as repairing hybrid and electric cars, installing solar panels and building wind turbines.

Governor Schwarzenegger says this Clean Energy Workforce Training Program is where economic growth starts.

“There are still people out there who think that protecting the environment will slow the economy down, but it’s quite the opposite here in California and all over the United States.”

Some business leaders say the green sector likely will be the only growth sector in this economy for a while.

Shrinking Salmon Populations

A federal judge says the Obama
Administration soon has to come
up with a plan to restore endangered
salmon runs to the Pacific Northwest’s
biggest rivers. Ann Dornfeld went
gill net fishing on the Columbia
River to find out what’s at stake:

(sound of a boat moving through water)

Gary Soderstrom is a fourth-generation Columbia River salmon fisherman. Even though it’s his work, on a sunny summer day there are few places he’d rather be than casting a gill net on this tranquil bay near the mouth of the Columbia.

“Just being this far from the dock, it’s just a whole different world! All the nights and the days I’ve put out here, I still feel good when I get out here.” (laughs)

Soderstrom – or Suds, as he’s better known – says gillnetters today catch salmon pretty much the same way his great-great-grandfather caught them. The main difference today is motors help fishers lay out and reel in their nets.

(sound of reel squeaking as net is laid)

“See how he’s layin’ up the bank here, and then he’s gonna go across. That’ll create a trap for the fish if he leads ’em over to the beach, and they might get confused.”

The technique might not have changed much. But this river has. These days, a dozen species of salmon and steelhead on the Columbia are listed as endangered. One of the biggest factors is the hydroelectric dam system that provides most of the power to the Pacific Northwest. Those dams keep young salmon from making it to the ocean. Suds says that’s why his son won’t be a fifth generation fisherman.

“There used to be several thousand fishermen on the Columbia at one time. Now there’s a couple hundred of us that are still active. Most guys like my son and them have went and got other jobs to try and raise families on.”

Federal law requires the government to restore the endangered salmon runs. For years, fishers and environmental groups have been calling for the removal of four dams on the Snake River, a tributary of the Columbia.

But the Clinton and Bush Administrations backed other plans to restore salmon runs. Those plans ranged from spilling a small portion of water through the dams to trucking baby salmon around the dams. Federal courts rejected those plans as insufficient. Now a federal judge has told the Obama Administration it has until mid-September to come up with a plan that goes far beyond the scheme President Bush proposed last year.

Ann Dornfeld: “What do you think is the chance that they’re gonna take out the dams?”

Gary Soderstrom: “Well, about like me winnin’ the Powerball! (laughs) I mean, don’t think it’s ever gonna happen, but realistically, it’d work.”

Suds says he’d also like to see tougher restrictions put on farmers who irrigate their crops with water from the Columbia.

“Irrigation systems, a lot of them are still water hogs. I think they should be forced into using the least amount of water they can get by with.”

It’s been about 15 minutes, and it’s time to reel in the nets.

(sound of reeling in nets)

We’ve brought in one 17-pound coho.

(sound of salmon hitting the floor)

But like most of the other fish caught on the Columbia these days, it was raised in a hatchery upstream.

Suds says for years he’s been volunteering his time on advisory councils and boards throughout the state to try to restore the habitat that once brought millions of salmon down the river the natural way. But what he’d really like to do is meet with President Obama and explain the river’s history to him firsthand.

“But in my situation, being a peon fisherman, you’ll never get to talk to a guy like him. Y’know, if you could bring him out here and show him what I’ve shown you today, maybe he’d have a clearer understanding of what’s going on out here.”

Suds Soderstrom says he wants the president to make good on his promise to let science dictate his policies, rather than politics – which always seem to favor development.

“Sooner or later you’re either gonna have fish or people. And the people seem to be winning.”

The new Administration has until September 15th to propose its plan to save endangered salmon. The federal judge who’s been overseeing the process for years has made one requirement: this time, the plan has to work.

More People, Fewer Fish

For decades now, we’ve been pushing
the limits on how much fish we can
catch. Mark Brush has been looking
at the recent trends:

If you look at the news, you get the picture. Declining salmon runs in British Columbia. Herring season cancelled along the West Coast. And tuna populations nearing collapse.

Over-fishing and damage to the environment are big problems in the world’s oceans, but you see declining fish stocks in the nation’s freshwater bodies as well.

Bill Carlson’s family has been fishing the Great Lakes since the 1870s. They catch fish called chub. But the chub are in serious decline.

“The chub population has just taken a real plunge, but we’re not sure what we’re experiencing is just a change in their habitat.”

These fish go through boom and bust periods. But since the chub’s main food source has disappeared, some biologists think the chub will have a tough time making a comeback.

So between over-fishing and environmental damage, the only good news seems to come from areas where there are strict rules in place – giving these fish stocks a chance to bounce back.
