Pharmaceuticals in Water Supply Causing Bizarre Mutations to Wildlife
By Greg Peterson
E Magazine
From inter-sex fish in the Potomac River to frog mutations in
Wisconsin, federal officials are spending this summer studying the
effects of pharmaceuticals such as pain killers and depression medicine
on the environment, because the drugs have turned up in America's
drinking water.
The cumulative effect of trace amounts of pharmaceuticals and
personal-care products in the water on humans isn't yet known, but the
Environmental Protection Agency (EPA) is taking preventative measures.
Pharmaceuticals have already been linked to behavioral and sexual
mutations in fish, amphibians and birds, according to EPA studies.
Better sensors have revealed that trace amounts of pharmaceuticals,
including narcotics, birth control, antidepressants and other
controlled substances, are in the drinking water and in U.S. rivers,
lakes and streams. The growing public debate on pharmaceuticals in
water will heat up this summer as experts on both sideas of the issue
try to convince the public that it's either much ado about nothing or
another example of humans ignoring early warning signs such as deformed
frogs -- the amphibian considered the canary in the coal mine when it
comes to water issues.
The EPA suspects that part of the problem is consumers flushing old and
unwanted drugs down toilets or drains. Americans are taking more drugs
than ever -- especially the aging baby boomer generation.
Pharmaceuticals were found in 80 percent of the samples taken during a
U.S. Geological Survey and EPA study of 139 streams in 30 states. Many
of America's wastewater treatment plants are not designed to remove
pharmaceuticals and personal care products, the EPA says.
A 1999 (EPA and German) study of pharmaceutical and other personal-care
products concluded the "undetectable effects on aquatic organisms are
particularly worrisome because effects could accumulate so slowly that
major change goes undetected until the cumulative level of these
effects finally cascades to irreversible change -- change that would
otherwise be attributed to natural adaptation or ecologic succession."
Meanwhile, federal officials continue to study the human health effects
of the pharmaceutical compounds found in water known as endocrine
disruptors, including possible links to neurological problems in
children and increased incidence of some cancers. Federal officials are
investigating a wide range of fish health problems in Cheasapeake Bay
and its watershed. Several studies of the Potomac and Shenandoah rivers
have revealed inter-sex fish, a wide range of "abnormalities in which
both male and female characteristics are present within the same fish."
The abnormalities include nine male smallmouth bass from the Potomac
River near Sharpsburg, Maryland (about 60 miles upstream from
Washington) that developed female eggs inside their sex organs.
Inter-sex bass were also found in a study three years earlier, after
fish kills about 170 miles upstream in the South Branch of the Potomac
in Hardy County, West Virginia.
The suspected causes include "previously banned compounds...such as DDT
and chlordane, natural and anthropogenic hormones, herbicides,
fungicides, industrial chemicals and an emerging group of compounds
that may act as endocrine disruptors," according to a 2006 summary of
the various studies prepared by the U.S. Geological Survey. Other
studies have linked endocrine disruptors to possible cancer in humans.
A recent survey of "cancer in Hardy County, where some residents get
drinking water from the South Branch, found rates of cancer of the
liver, gallbladder, ovaries and uterus that were higher than the state
average," according to the Washington Post.
Officials are investigating whether there is a link between the
increased cancer rates, river water and altered fish including the
possible connection to wastewater discharges containing trace
pharmaceuticals. This is disconcerting to residents of metro
Washington, D.C., because the Potomac River is the main source (75
percent) of drinking water for 3.6 million residents, including the
Maryland and Virginia suburbs.
Regulatory issues won't be tackled for years to come, but the EPA isn't
waiting for more study results before taking action. The EPA is
educating the public and funding pharmaceutical programs by concerned
groups and state and local government agencies.
In the short term, numerous grassroots and government pharmaceutical
collection projects have sprung up worldwide from police stations to
pharmacies to church parking lots.
One of the larger efforts was held in April in northern Michigan. A
coalition called the Earth Keepers opened 19 free drop-off sites over a
400-square-mile area, geographically the largest one-day pharmaceutical
collection in U.S. history. Funded by the EPA, Thrivent Financial and
others, the faith-based collection involved 400 volunteers from more
than 140 churches and temples, university students, an American Indian
tribe and two nonprofit environmental groups.
The nonprofit Superior Water-shed Partnership arranged the technical
side of the collection including law enforcement officers and
pharmacists at all collection sites because of strictly enforced
federal laws governing controlled substances with po-tential for abuse
like narcotic pain medicine.
"The Earth Keeper network is one of the most effective tools for
addressing Great Lakes pollution," said Carl Lind-quist, director of
the Superior Watershed Partnership. "The pharmaceutical collection was
a proactive approach to a serious environmental issue that is just
getting national attention."
The U.S. Fish and Wildlife Service and the American Pharmacists
Association recently launched "SMARxT DisPOSAL," a public education
project about pharmaceuticals and fish that includes a traveling
awareness show, brochures and a website for consumers and health
professionals. The campaign will visit select U.S. cities this fall and
be expanded in 2008.
Studies show that pharmaceuticals in the environment break down fairly
quickly but get replenished at an alarming rate because of increased
American drug use. America's huge healthcare network is addressing the
problem of improperly disposed pharmaceuticals by education and "green
chemistry" -- encouraging drug companies to develop medications that
break down more quickly.
Hospitals for a Healthy Environment (H2E) held a pharmaceutical waste
management summit in May for its members including 1,600 hospitals that
run 4,000 clinics and long-term care facilities. Hazardous chemical
incinerators are used by many hospitals to dispose of unused
pharmaceuticals. Industry experts say these incinerators have scrubbers
and are closely monitored, yet incineration of medical waste "is highly
problematic" and other solutions are needed.
"Incinerators are not the solution, but we knew we had to get
pharmaceuticals out of sewers because waste water treatment plants are
not capturing it," says Laura Brannen, H2E executive director. Green
chemistry and a careful reduction in the amount of pharmaceuticals used
by hospitals are among the "lifecycle approach" to solutions that
Brannen supports.
Hazardous chemical waste management is heavily regulated, but
pharmaceutical cleanup hasn't kept pace, according to H2E. "The current
EPA regulations were designed to handle 55 gallon drums of chemicals
out of industries," Brannen says. "The EPA needs to reassess their
regulations ... they [haven't] updated the list of hazardous chemicals
in pharmaceuticals in over 20 years. We must address the source --
using less and making what we do use as environmentally preferable as
possible. If we are only dealing with the pharmaceutical waste at the
back door we are going to be buried."
In communities without pharmaceutical collection programs, the EPA is
also concerned about diversion -- unused drugs being stolen out of
trash cans. They recommend crushing pills or capsules and mixing the
drugs with cat litter or coffee grounds. The recreational use of
prescription medicines is now the second worst drug problem facing
American teenagers, according to the White House Office of National Dug
Control Policy.
The White House says 6.4 million Americans admit abusing prescription
drugs and most say they got the pharmaceuticals from friends or
relatives. Pharmaceutical collections are one of several tools being
used to reduce the problem by 15 percent over three years.
"While EPA continues to research the effects of pharmaceuticals in
water sources, one thing is clear: improper drug disposal is a
prescription for environmental and societal concern," says EPA
Administrator Stephen L. Johnson. "Following these new guidelines will
protect our nation's waterways and keep pharmaceuticals out of the
hands of potential abusers."
