U.S. Pharma Factories Dumping Huge Quantities of Drugs Into Public Sewers, Rivers and Waterways
(NaturalNews) In spite of claims by pharmaceutical companies
that they do not discharge their products into the water supply,
federal researchers have discovered that waters downstream
of pharmaceutical plants are more heavily contaminated
with drug residue than waters elsewhere in the country.
In one study,
conducted by scientists at the U.S. Geological Survey (USGS),
researchers tested the water entering two water treatment plants
down the sewer line of several pharmaceutical factories,
as well as at other plants not receiving sewage from drug plants.
Researchers discovered drugs at
"much higher detection frequencies and concentrations"
at the plants receiving effluent
from pharmaceutical factories.
Drugs detected included opiates,
a barbiturate and a tranquilizer.
In a second study,
researchers from the Environmental Protection Agency
tested the water entering a wastewater treatment
plant in the city of Kalamazoo, Michigan,
down the sewage line from a Pfizer drug factory.
They found that the water entering the
plant was exceptionally high in levels
of the antibiotic lincomycin,
which the factory was producing at that time.
"There's some product going down the drain,"
said Bruce Merchant,
the city's public services director.
Prior studies have shown that lincomycin
can cause genetic mutations,
and that it encourages the growth of cancer
cells when combined with minute
concentrations of a number of other drugs
that are common in surface water.
The two studies are among the first to test longstanding claims
by the pharmaceutical industry that factory emissions are not a
significant source of drug residue in drinking water supplies.
"It's critical that those types of assumptions
are confirmed through real testing,"
USGS researcher Herb Buxton said.
Research outside of the United States also suggests that
pharmaceutical companies are major sources of drug pollution.
In Switzerland, a test by drug company Roche found
that a full 0.2 percent of active drug ingredients enter
the environment during the manufacturing process.
Another study found that 100 pounds of the antibiotic ciproflaxin
were entering the water every day from a drug factory in India.
