A new study is looking at just
how well wastewater treatment
plants remove household chemicals
and pharmaceuticals from water.
Samara Freemark reports
on why some researchers are worried
that the plants aren’t doing a good
enough job:

Most wastewater treatment plants clean water with a mix of chemicals and bacteria. But that process is decades-old. And it was designed mostly to deal with industrial pollutants.

Some people say treatment plants might not be doing a good job taking out other pollutants like household chemicals and pharmaceuticals. In fact, the treatment process can actually cause many of these pollutants to mutate – for example, some detergents break down into compounds that cause reproductive problems.

Anthony Hay is studying the issue at Cornell University.

“Hopefully they’re degraded into something non-toxic, but in some cases microbial degradation of some pollutants can actually make things worse. We need to understand what those changed products do, how they behave, and what risks they might pose.”

That’s what Hay hopes his study will help clarify.

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.

Acupuncture for the Masses

  • Some consumers choose alternative treatments, like acupuncture, because they want a smaller environmental footprint from their medical care. (Photo courtesy of the National Institutes of Health)

Acupuncture has been used as a medical treatment in Asia for thousands of years. It’s catching on in this country, but it can be pricey. Now a new kind of low-cost acupuncture clinic is springing up with a goal of bringing acupuncture to the masses. As Ann Dornfeld reports, this new type of clinic might just be healthy for the planet, too:

Acupuncture has been used as a medical treatment in Asia for thousands of years. It’s catching on in this country, but it can be pricey. Now a new kind of low-cost acupuncture clinic is springing up with a goal of bringing acupuncture to the masses. As Ann Dornfeld reports, this new type of clinic might just be healthy for the planet, too:

Esther “Little Dove” John is lying on a treatment table with the same blissful smile as someone who’s just had a massage. Except she’s about to get stuck with a couple dozen needles.

“Anything in particular you want to focus on today?”

“I have tingling in my fingers and numbness in the toes.”

Acupuncturist Jordan Van Voast taps fine steel needles into John’s hands; then her stomach, her legs, and her ears.

“All of a sudden, my body just relaxed.”

This would be a typical scene from an acupuncture clinic. Except the recliner that serves as John’s treatment table is just one in a circle of ten. It’s a treatment model called “community acupuncture.”

Jacque Larrainzar is getting treated in a chair across from John. She used to go to a standard acupuncture clinic with private rooms. But she prefers the communal style of this Seattle clinic, called – wait for it – “CommuniChi.”

“The feeling is very different. Seeing other people relax and just giving themselves the opportunity to heal is, in itself– I think it helps you to focus on yourself and heal.”

Community acupuncture clinics are designed to make acupuncture affordable to people at all income levels, regardless of insurance. Patients pay a sliding scale fee – as little as 15 dollars per treatment. It’s 60 dollars or more at a standard acupuncture clinic. Community acupuncture keeps costs down through low overhead: using one treatment room and recliners cuts down on electricity and laundry costs. And CommuniChi co-owner Serena Sundaram says that also means a smaller environmental footprint.

“All of those things are really different even than a regular acupuncture clinic, which is already a smaller footprint than a Western practice.”

You don’t need big, high-tech equipment for acupuncture or even electricity — just a place to lie down and a handful of tiny needles.

Patient Esther “Little Dove” John says she’s glad that acupuncture doesn’t involve pharmaceuticals.

“If I were using the mainstream treatment for my condition, I’d be expelling those chemicals into the environment and the fish would be taking it and the birds would be drinking it.”

Scientists have found high levels of pharmaceuticals in the water downstream from water treatment plants. They’re worried about the effect on fish.

Emily Wong is a physician at the University of Washington Medical Center. She practices Western medicine, but also studied acupuncture. Wong says there’s extensive evidence that acupuncture helps with a lot of health problems where Western medicine falls short, like headaches, back aches, and nausea.

But, she says acupuncture is no panacea. She says some acupuncturists claim to be able to treat conditions like kidney stones without scientific evidence to support their claims.

“I see it as being more similar to, for example, physical therapy as a modality that treats many conditions quite well, and as an alternative to a surgical approach or perhaps a pharmacological approach to some conditions.”

If acupuncture works as well or better than a stay at the hospital or a prescription of drugs, it could have a lot lower impact on the environment. And if the new community clinics bring more people to acupuncture, it’s possible the earth will get a little relief too.

Holistic Medicine for Pets

Veterinarians who use a holistic approach to healing make up only about one percent of

Veterinarians who use a holistic approach to healing make up only about one percent of
all veterinarians in the country. But their numbers are growing. And so is their
popularity among pet owners. The mainstream veterinary community wants to see more
science behind the methods used by holistic veterinarians. Kinna Ohman
reports:


The snow’s starting to fall as I arrive at a small, yellow farmhouse. I hurry my dogs up to
the front door and step inside.


(Sound of dogs)


This is the veterinary clinic of Dr. Konrad Kruesi. He’s a holistic veterinarian with a
different approach to animal healthcare. One thing Dr. Kruesi does is to take a lot of time
teaching clients how to help heal their animals. He says it’s hard work but most clients
embrace the idea:


“Nine out of ten of them do a wonderful job. They do make food, they learn
massage, they learn to stretch their animal, they’ll buy air filters for the allergic
individual. They see that healing is a progression.”


Pet owners who switch to holistic veterinarians such as Kruesi swear by this approach,
and Neil and Joannie Alcorn are perfect examples. They found Dr. Kruesi after the local
veterinarians said they’d run out of options to help their dog Poppy. Poppy developed
complications after picking up a rare parasite, and the veterinarians tried everything from
exploratory surgery to steroids. Neil Alcorn says after ten months of this, they told him
to prepare for his dog’s death:


“The vets were now basically saying you should get prepared for the fact Poppy’s
not going to last much longer. And they didn’t have anything else to offer.”


But the Alcorns decided to keep trying. They researched holistic veterinarians and came
across the name of Konrad Kruesi. Right away, Dr. Kruesi says he taught the Alcorns
how to prepare fresh, homemade food for their dog. They started with a simple puree of
natural foods and offered it to Poppy. Within a few days, their dog was showing more
interest in food for the first time in months. Dr. Kruesi then added natural supplements to
help build up Poppy’s strength. Neil Alcorn says the good results continued:


“It was so remarkable. Within between two to three months, she had been weaned
off of every single medication, including the steroids, and was beginning to function
again as a living being.”


Veterinarians such as Kruesi say this kind of care shows how a natural and holistic
approach should be part of standard veterinary treatment, but there’s no policy within the
mainstream veterinary community to link clients such as the Alcorns with holistic
veterinarians.


Dr. Craig Smith is with the American Veterinary Medical Association. He says most vets
are cautious about fully supporting holistic veterinary medicine until they see more
science:


“Unfortunately, for too many of the complementary and alternative veterinary
medical therapies, including some of the nutritional recommendations, we don’t
have the science. I’m not saying it doesn’t work, it obviously does work for some
animals. The question is how can you, as a practicing veterinarian, develop your
level of confidence to say this is going to work for your dog.”


So the larger community of veterinarians is reluctant to endorse holistic medicine as part
of standard animal care, but this doesn’t stop pet owners such as the Alcorn from
continuing to use the holistic methods for their animals. They’re much more involved in
their animals’ healthcare, from preparing meals to being part of decision making at the
local veterinary office. Neil Alcorn says they don’t need to go further than Poppy for
proof it works. She’s still going strong six years after the local veterinarians gave up on
her:


“She was sixteen years old this last September. This weekend I took her hiking for
several two to three mile hikes. And she still plays with us. She’s gray, she’s
showing her age but then so are we all. And we have every hope of sending birthday
congratulations to Dr. Kruesi on Poppy’s seventeenth birthday next September.
(laughs) Even to us, it’s a bit of an amazing story.”

Asian and Black Kids Misdiagnosed

A new study has found that a test used to identify kids with asthma could
misdiagnose children of certain ethnic backgrounds. Karen Kelly has the story:

Transcript

A new study has found that a test used to identify kids with asthma could
misdiagnose children of certain ethnic backgrounds. Karen Kelly has the story:


Until now, doctors looked for a standard level of nitric oxide in a child’s breath when diagnosing asthma.
But a study of 650 kids in Detroit and neighboring Windsor, Ontario led to a surprising discovery: healthy kids of Asian descent had two times more nitric oxide than what’s
considered normal, and healthy African-American kids exhaled 50 percent
more of the gas.


Dr. Thomas Kovesi conducted the study, which was published in the journal
Chest.


“If based on this test, a child gets diagnosed with asthma when they don’t have
asthma, it’s possible that they’ll end up on medications the child won’t benefit
from. Every medication has potential side effects.”


Kovesi tells parents to ask their doctors to consider their child’s ethnicity if the
kid is taking an exhaled nitric oxide test.

Preserving Cultural Remedies

  • Faith learned about the use of many herbs for home remedies from her father in Louisiana when she was a small girl. (Photo by Kyle Norris)

When most of us get sick we go to the doctor and get medicine. But
some people are holding onto the old ways of healing. And many
people think we could learn a lot from the old ways. Kyle Norris has
this story:

When most of us get sick we go to the doctor and get medicine. But
some people are holding onto the old ways of healing. And many
people think we could learn a lot from the old ways. Kyle Norris has
this story:


The small store is called Nature’s Products. It’s in a neighborhood with
a lot of abandoned buildings and store-front churches. When you walk
inside the store, the smell of incense clings to your clothes.
Green plants hang in the windows, and there are jars and jars of bulk herbs lining
the shelves.


Gary Wanttaga opened the store thirty years ago. He’s always been
interested in natural healing techniques and herbal medicine. That all
might sound new-agey, but this place is not new-agey at all. The
reason Wanttaga opened the store in his hometown of Detroit was
because he wanted to help the people who lived here:


“In lot of urban areas people are very limited on resources. They’re limited
with money. They’re limited with shopping resources. And this is one way
that I try to give back to the community”


Wanttaga says one of the main reasons he’s stayed in Detroit is because of
his customers. They’re some of his biggest teachers. Many of his
customers are older African-Americans. They came from the South to work
in the factories during World War II. When they came they brought with
them a cultural knowledge of herbs and natural healing techniques.


One of his customers is 72-year-old Faith. That’s her legal name – just
“Faith.” She grew up in a segregated farming community in Louisiana. Her
father was a farmer, and he taught her all about the herbs:


“I’m the youngest child of all, so I’m the baby. And he would often let me
ride on his shoulder. And sometime I’d be saying ‘Papa, what is this?’ and he
would tell me what that was, we’d be walking through the fields and he
would tell me what was, and he would tell me different things, what you use this for
what you use that for. I had 100 questions. Boy, I was a kid I had a 100
questions.”


She says back then, everyone knew about the herbs, and everyone used
them. At that time, people who were poor or black or who lived in rural
areas did not often have the option of going to a doctor. And so they turned
to the plants and trees around them for medicine, and they developed a great
knowledge about what did and didn’t work to keep people healthy:


“The pine tree was used for many things. Because it’s one of things where
you get turpentine from. It was definitely used for healing. And we used
turpentine for sores. And it works today! If you get a cut and you put
turpentine on it immediately as soon after you hit it, it will never be sore.”


Herbs were out first form of medicine. That’s what Suzanna Zick says.
She’s a naturopathic physician who teaches at the University of
Michigan. She says we have a collective knowledge about herbs that’s
thousands of years old. She says when you compare that to what
modern-day science knows about herbs, it’s not much of a comparison:


“In a sense we have just a tiny little window that science shows us, as
compared to the long use.”


Zick says we could learn a lot from these folks and the knowledge they
have, but not many researchers are studying people like the customers
here in Detroit:


“I think that we can actually learn what herbs they’re using a lot of and
what for. Because I think those are probably the ones that would be of
most interest. In particular, it’s a good question too if they’re using
them with conventional medications, it’s for safety issues. But also if
this is their primary health care for some of them, if it’s working, then
this is a very inexpensive way of providing health care for people who
might otherwise get none.”


Everyone we heard from in this story said the same thing. For us to
have good health, the old-school ways of healing can work hand-in-
hand with modern-day doctors and science. But the people who know
about the herbs are growing older and dying, and their knowledge is dying with them.
