The nation's military toxics scandal deepened last week with two new
revelations: (1) the Department of Defense sent a report to Congress
announcing it has discovered 3081 additional chemically contaminated
sites besides the 14,401 they had reported earlier; this increases the
officially-reported number of poisoned military sites by 21%.
(WASHINGTON POST 3/29/91, pg. A4.)
Secondly, the U.S. Environmental Protection Agency (EPA) revealed this
week that the engineers who built nuclear weapons at the Hanford,
Washington, reservation in the 1950s dumped 127 millions gallons of
highly radioactive waste into the ground just a few miles from the
Columbia, the nation's 4th largest river. (NEW YORK TIMES 3/28/91, pgs.
1, B6.) The TIMES reported that "Dirt from the reservation may be as
dangerous as highly radioactive wastes stored in special tanks. But the
federal government is still struggling to measure the level of
contamination and has little idea of how to contain the danger. Wind,
rain, birds, animals, and underground water flow can all spread the
radioactivity to the Columbia River, which forms one border of the
reservation, and even further afield."
3081 More Military Points of Blight
Summarizing the Defense Department's own report to Congress on the 3081
new contaminated military sites, the WASHINGTON POST said, "According
to the report, some of the nation's worst toxic waste problems occur at
military bases, where the testing, manufacture, and maintenance of
weapons resulted in pollution of the local environment. Poisonous
substances dumped on land have penetrated deep into underground
currents of water, threatening nearby streams or drinking water wells."
The report lists 1855 individual military bases (17% over last year's
1579) and installations as having contaminated sites; many
installations have several contaminated sites.
Radioactive Wastes Bulldozed into Trenches
The radioactive wastes newly discovered in the soils at Hanford contain
two long-lived elements: Technetium-99, with a half-life of 212,000
years and iodine-129, with a half-life of 16 million years. The half-
life of a radioactive element is the time it takes for half of it to
change into a less harmful substance via natural radioactive decay. At
the end of 10 halflives, only a small proportion (1/1024, or 0.09%) of
the original material remains. For this reason, scientists say 10 half-
lives is the duration of the hazard for any radioactive element. Thus,
the soil at Hanford will remain radioactive with technetium-99 for 2.1
million years and with iodine-129 for 160 million years. Homo sapiens
(modern humans) have inhabited the earth for less than 1 million years.
Radioactive iodine is a particular hazard to humans because iodine is
an essential element that we all need in our diet to avoid thyroid-
deficiency disease. Therefore, the human body selectively extracts
iodine from food, water and air, storing it mainly in the thyroid
gland. Radioactive and nonradioactive iodine are identical from a
chemical viewpoint, so humans (and other living things, for that
matter) are unable to differentiate one from the other, storing both
kinds in the thyroid. Radioactive iodine causes fatal thyroid cancer.
Until now, nuclear engineers and scientists have said that the main
engineering challenge they face is to figure out some place to stash
these wastes for millions of years in a way that guarantees that future
generations will not be harmed by our blunders. This week's revelations
at Hanford made the problem seem even more difficult: Randall F. Smith
in the DOE's regional office in Seattle said, "the technology may not
exist to recover some of the wastes dumped in the dirt" at Hanford. The
implications of these words are ominous; if Mr. Smith is right, the
U.S. military has already set in motion the unavoidable radioactive
contamination of one of the nation's major rivers.
The TIMES put this new revelation into context as follows: "Hanford was
already known to be one of the most polluted radioactive dumping
grounds in the world.... More than five years after the complex began
to open itself to outside scrutiny, such skeletons continue to come to
Critics point out that the nation's nuclear scientists today are
continuing to create new "skeletons"-more of the same radioactive
materials--still without any idea where to put them for safety. Most of
the wastes are temporarily stored in tanks near where they are made.
However, the federal Department of Energy "is still discharging
chemical and radioactive wastes into the soil [at Hanford] in 27
individual streams, even as engineers try to find ways to clean up past
releases," the TIMES reported last week.
Technetium-99 and iodine-129 are not the only radioactive elements
dumped into the ground at Hanford. The wastes also contained strontium-
90 at concentrations "thousands or tens of thousands of times higher
than allowable limits for public access," according to reports written
by General Electric at the time the dumping occurred in the 1950s.
Strontium-90 is much more radioactive than technetium-99 or iodine-129,
and therefore is more hazardous but also more short-lived, with a half-
life of 28 years (meaning it will be gone in "only" about 300 years).
Strontium-90 mimics calcium in the environment, entering food chains
(including cows' milk) and ending up in human bones and teeth where it
is a potent carcinogen.
At the time this massive dumping occurred, General Electric was running
the Hanford reservation under contract to the old Atomic Energy
Commission (AEC), which has since become the Department of Energy. It
is not clear why government authorities have not tried to force General
Electric to pay for the cleanup, rather than taxpayers. Cynics
speculate that one reason may be General Electric's ownership of NBC
television. Good TV coverage is essential to a successful campaign bid
by any national political candidate, even a popular incumbent.
In addition to strontium, the dumping included unspecified quantities
of plutonium-239, which has a half-life of 24,400 years; plutonium is
among the two or three most potent carcinogens ever discovered.
According to the TIMES, the wastes began moving through the environment
almost immediately after they were dumped into trenches. Secret reports
unclassified two years ago, said that as early as May, 1958, workers
found radioactive rabbit and coyote dung scattered over a 2000-acre
The TIMES reported July 31, 1990 (pgs. A1, A16), that 177 tanks on the
Hanford reservation holding millions of gallons of radioactivity were
in danger of exploding. The TIMES said then, "after years of secrecy
and sometimes outright falsehoods in public statements, the Department
of Energy has recently" acknowledged the danger of explosions.
