Sometimes we hear complaints that environmental regulations stop us from doing what we want with our property.
Environmentalists say there’s one issue where doing the green thing can attract a bunch of red tape.

Shawn Allee reports it’s about using rain water to flush our toilets.

This story starts at a forest preserve in Lake County, Illinois, north of Chicago.

Jill Stites is here to show off the forest preserve’s custom-built welcome center.

Stites: This building was built for people to come out and see what people could do in their own homes.

In other words, the idea was, we could do it, it didn’t break the bank entirely, here’s something you might want to try, that sort of thing?
Stites: yes, you can really do green building in a responsible way.

Stites shows me how the building collects rain water from the roof.
That keeps rain out of sewers.
That way, the local waste-water treatment plant doesn’t waste chemicals and electricity to purify rainwater.
After all, rainwater’s already clean and you can store it in cisterns, like this one.

Stites: It collects water off of the roof and goes directly in there. and there’s a spout on the bottom of the cistern that you can hook up a hose to and water your flowers with.

But Stites’ building wanted bigger bragging rights.
They wanted to prove people can collect rain water for more than just flowers.
You can use it for something more urgent: flushing your toilet.

Stites: you don’t need drinking water to flush your toilet. you’re saving the water from going to the storm sewers to be treated to come back as drinking water when that’s not necessary.

There was trouble, though.
The forest preserve district couldn’t get a permit to use rain water in the toilets.

It wanted a connection to city water, as a kind of backup.

But the state worried untreated rain water might somehow contaminate the city’s drinking water.

It took years to get special permission.

Stites: We’re bragging about it. It’s been in the paper about the possibility of it happening and we’re hoping by summer that it’s going to be a fact.

Well, the Lake County Forest Preserve District got its permit, but it won’t let the issue die.
It wants average homeowners to have an easier time, so do environmental groups.

Ellis: It’s a time-consuming process. If we’re going to have more individuals and business doing this, it’s just going to become a bureacratice mess if they have to get variances every time.

This is Josh Ellis.
He’s with the Metropolitan Planning Council in Chicago.
He wants rain collection for toilets to go mainstream in Illinois, but state law needs an update.

Ellis: It would just be a matter of course instead of a special process just to run your toilets a little bit differently.

He says engineers and plumbers have proven rain water collection can work for toilets, safely.

Ellis: We just need to upgrade the plumbing code and I think it will be smooth sailing from there.

Maybe smooth sailing … if you have the cash.
I ask an industry leader for specifics.
His name’s Joe Wheeler, and he’s with the American Rainwater Catchment Systems Association.
The U-S Environmental Protection Agency estimates, each year the average household spends just 200 dollars on water.
Wheeler says, for a rain water collection system …

Wheeler: You could do a really good job for about 4500 to 15,000 dollars. Every house is different. We’re not talking McDonald’s Big Macs here, we’re talking every one of them is a unique situation.

Wheeler says overseas, using rainwater for toilets is common and cheap.
Take Germany, for example.

Wheeler: Basically when you go into a home, you don’t know … you can’t tell the difference.

But Wheeler says German homes and businesses get pushed toward rain harvesting.

Wheeler: People would actually get a rebate on their waste water and that gave the whole market in Germany a critical mass.

It doesn’t work like that here, so in the U-S, rain harvesting for toilets is nowhere near critical mass.

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

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.”

Drugs in the Water

  • There is some confusion about what to do with unused medications (Photo source: Shorelander at Wikimedia Commons)

The drugs we take are showing up in our drinking water, and they’re showing up in fish. The federal government’s now saying that in most cases, you should never flush unused drugs down the drain. There are safer ways to dispose of them. But even if you want to do the right thing, it’s not always easy. Rebecca Williams takes a look at what you should and should not do with your medications:

The drugs we take are showing up in our drinking water, and they’re showing up in fish. The federal government’s now saying that in most cases, you should never flush unused drugs down the drain. There are safer ways to dispose of them. But even if you want to do the right thing, it’s not always easy. Rebecca Williams takes a look at what you should and should not do with your medications:

In the U.S., there are about 12,000 brand name and generic drugs on the market. And who knows how many over the counter drugs.

Scientists are finding many of these drugs in our water. Everything from caffeine, to allergy and anti-cancer drugs, to antidepressants.

Now, they’re finding these drugs at very low levels. But they’re pretty much everywhere.

An Associated Press investigation found trace amounts of pharmaceuticals in the drinking water of more than 40 million Americans.

“You know, we don’t think it’s enough to cause public harm but honestly nobody’s sure.”

That’s Sahar Swidan. She’s a pharmacist.

Right now, Swidan’s going through a five foot tall box of prescription drugs that people have brought to her store in Ann Arbor, Michigan. They might be expired, or just not needed anymore.

(sound of pill bottle shaking)


“Asthma medications, growth hormones for patients – so really the gamut could be anything and everything.”

A disposal company picks up the drugs about once a month and incinerates them.

Swidan’s drug take-back program is pretty rare. Many pharmacies are not set up to collect unused drugs.

One reason is, it takes a lot of work. Swidan has to sort through the drugs and make sure there aren’t any controlled substances – things like narcotics. It’s illegal for pharmacies to take these back in most cases.

The Drug Enforcement Agency is talking about revising their disposal rules for controlled substances. But for now you usually have to get rid of them yourself. So, how do you do that?

You can dissolve pills or caplets in water, and mix in kitty litter or coffee grounds. That’s to make the stuff look gross and undesirable. Then dump it all into ziptop bags, wrap it up in duct tape, and throw it away.

But to make things more complicated, there’s still a short list of drugs that you’re supposed to flush down the drain. The Food and Drug Administration says the drugs on this list are too dangerous to toss in the trash.

Connie Jung is with the FDA’s pharmacy affairs department. She says the drug label will tell you if you’re supposed to flush them.

“For the small number of prescription drugs that have flushing recommendations they have these because the drugs are strong narcotic pain relievers or other controlled substances. These drugs can be dangerous to those who aren’t supposed to be taking them, particularly children or pets.”

Jung says the FDA is currently reviewing disposal methods for these kinds of drugs… because flushing them down the toilet is starting to raise some questions.

An even bigger problem is that most of the drug residues getting into our water are coming from drugs we take and excrete.

Bryan Brooks is a researcher at Baylor University. He recently found low levels of seven drugs in fish caught near wastewater treatment plants. He says these sewer plants just can’t filter out drugs.

“These wastewater treatment facilities were largely not designed to treat to really ultra low levels. Compounds like birth control medications can be active at low part per trillion levels.”

Right now Brooks is trying to sort out what effects drugs are having on fish.

Hormones like estrogen appear to be feminizing male fish. Antidepressants might change how fish behave. And no one’s sure how drugs might be affecting our drinking water.

Brooks says one thing that can be done at the treatment plant is adding reverse osmosis filters. But they’re expensive.

Brooks says there’s not much we can do about excreting drugs, but at the very least we shouldn’t be flushing drugs down the drain.

Cargo Ships Oppose Proposed Ballast Rules

A proposed bill requiring ocean-going foreign vessels to dump their ballast water before they enter the Great Lakes is receiving strong criticism from shipping groups. The Great Lakes Radio Consortium’s Tracy Samilton reports:

A proposed bill requiring ocean-going foreign vessels to dump their ballast water before they
enter the Great Lakes is receiving strong criticism from shipping groups. The Great Lakes Radio
Consortium’s Tracy Samilton reports:


Helen Brohl of the Great Lakes Shipping Association agrees that the introduction of invasive
species into the lakes from ballast water is a problem. Zebra mussels alone have caused about a
billion dollars in damage since they got into the Great Lakes from foreign vessels in the
1980s. But Brohl says a bill proposed by a Michigan Congresswoman is too radical. She says
requiring ships to dump virtually all their ballast water before entering the Great Lakes would put
an end to international shipping in the area.


“When you have no cargo on a ship you have to use ballast water to even out the vessel in rough
weather. It’s a very dangerous thing not to have ballast water on board.


Brohl says a better approach is to require ships to use stringent ballast water management. That
includes regular flushing and keeping sediment out of the water.

Intimate Disclosure

Warm weather means sprinklers, car washings, and
jumbo plastic pools. In the Great Lakes region, where water is
virtually everywhere, we sometimes need to be reminded that water is a
precious resource. Great Lakes Radio Consortium commentator, Julia
King, can think of at least one way to conserve – but technology is
thwarting her effort:
