OXNARD - For 39 years, millions of gallons of wastewater contaminated with heavy metals and several radioactive isotopes was discharged by Halaco Engineering Co., which operated a scrap metal salvage facility located adjacent to the Ormond Beach Wetlands in Oxnard until 2004.

The solids that settled out of the wastewater were piled onto a slagheap that grew 40 ft. high and encompasses about 28 acres. According to the Regional Water Quality Control Board, the slagheap emitted ammonia and radioactive elements such as thorium and uranium-238. Unlined ponds leaked contaminated wastewater into the wetlands, the ocean and groundwater.

Thorium is naturally occurring, but has been shown to cause an increase in cancers of the lung, pancreas and blood in workers exposed to high levels of it in the air.

On March 7, the Environmental Protection Agency (EPA) proposed adding the Halaco site to the national list of Superfund sites. Once on the list, federal funds can be issued to help with cleanup."

What is depleted uranium?

Depleted Uranium: "

Uranium Munitions = Depleted Uranium

half life of 4.5 billion years *

What is depleted uranium? Natural uranium ore from the mine goes through an enrichment process designed to separate uranium 235 (U-235), the isotope used for nuclear weapons and nuclear reactors, from uranium 238 (U-238), a low-level radioactive by-product. The highly radioactive isotope U-235 accounts for less than 1% of mined uranium; nearly all the rest is U-238.

The vast quantity of highly toxic metal (U-238) generated by this process is called "depleted uranium" or "DU." DU emits primarily alpha radiation, and its half-life is thought to be about the age of the Earth, or 4.5 billion years. DU is approximately 2.5 times denser than iron and 1.7 times denser than lead. This high specific gravity means that, as a projectile fired from a tank or aircraft, it carries enough kinetic energy to blast through the tough armor of a tank. Furthermore, the impact of this penetration generates extreme heat. DU is pyrophoric, meaning that it burns on impact and can set the target on fire. DU is easy to process and endless quantities can be obtained free from the Department of Energy (DOE), which controls DU and considers its use in munitions to be "utilization of waste material." Retrieved 08/11/04 http://www.chugoku-np.co.jp/abom/uran/special/index2.html

As U-238 breaks down, an ongoing process, it creates protactinium-234, which radiates potent beta particles that may cause cancer as well as mutations in body cells that could lead to birth defects.

When a depleted uranium round hits a hard target, as much as 70 percent of the projectile can burn on impact, creating a firestorm of depleted uranium particles. The toxic residue of this firestorm is an extremely fine insoluble uranium dust that can be spread by the wind, inhaled and absorbed into the human body and absorbed by plants and animals, becoming part of the food chain. Once in the soil, it can pollute the environment and create up to a hundredfold increase in uranium levels in ground water, according to the U.N. Environmental Program.

The United States military has never confronted an opponent that used depleted uranium. Most exposure to American military personnel has been a result of fire from their own forces. MATTHEW L. WALD The New York Times Oct 19, 2004

Radioactive water near Hopi springs

Two Hopi villages and their wells lie in the path of a radioactive plume of water

A plume of radioactive water is moving toward two Hopi villages, threatening to contaminate wells and spring-fed drinking water for about 1,000 residents.

Nothing has been done to contain or remove the waste.

Hydrologists, geochemists and consultants have said the radioactive waste appears to have been taken from a Cold War-era uranium milling site near Tuba City and buried at a public dump 1 mile east of the communities.

The villages of Upper Moenkopi and Lower Moencopi have seen levels of radioactive uranium in their ground water that appear to be above normal for the area, though these levels are still well within drinking water standards established by the U.S. Environmental Protection Agency.

Hopi water managers fear these readings are a sign the leading edge of the radioactive plume might already be hitting the villages' groundwater supply.

"It's a matter of jeopardizing people's lives" if nothing is done, said Harris Polelonema, community service administrator for Lower Moencopi.

Everyone's trash heap

Tuba City's dump was opened by the Bureau of Indian Affairs a mile east of town. It was used for more than 40 years until it was covered with sand in 1997. Situated on the boundary marking Hopi and Navajo lands, the dump was a disposal site for medical waste, animal carcasses, paint, batteries and tires, nearby residents said in interviews.

"We have no paper record of what's actually in the site," said Lynelle Hartway, an attorney working for the Hopi Tribe.

This makes it difficult to assign responsibility for the estimated $23 million cost of removing contaminants thoroughly, which is what both tribal governments want.

Test wells at the dump show uranium levels up to 10 times higher than the level the EPA considers safe for drinking water. This uranium plume appears to be moving south and west toward Upper Moenkopi and local washes.

If the villages' water and the Navajo Aquifer were to become contaminated, the uranium could bioaccumulate in produce that the Hopi people depend on and in natural vegetation consumed by the livestock, researchers fear.

"While the problem isn't too dramatic based on concentration, the cumulative effect over time could be," said geochemist Bill Walker, who analyzed the site.

No one's responsibility

People working for both tribes have been seeking to have the dump cleaned up and the radioactive water pumped out, but they have made little headway over the years.

The Department of Energy won't clean up the dump because the Navajo Nation didn't raise the issue soon enough and because it contains much more than just radioactive waste.

The tribe should have raised the issue before the department's congressional authority to conduct cleanups under the Uranium Mill Tailings Remediation Act expired in 1998, the department told Navajo Nation President Joe Shirley Jr. in letters.

And the EPA has been hesitant to designate the dump a federal cleanup site, because it isn't an immediate danger.

"The emergency response office decided there was not an emergency and immediate risk to the public," said Andrew Bain, EPA's remedial project manager for Superfund in the West.

That leaves open the possibility of trying to bill cleanup costs to the company that merged with Rare Metals Corporation: El Paso Natural Gas Company.

Building a case

Some EPA and other government officials have suggested the radioactive waste in the dump could not be the result of uranium milling operations just a few miles down the road. Or perhaps, they said, it occurred naturally.

But during a geochemical analysis at the dump, Ray Johnson and Laurie Wirt, of the U.S. Geological Survey, found similarities between the uranium found in the dump and the types of ore milled at the nearby Rare Metals Corporation uranium mill.

Wirt died in a boating accident in 2006.

Walker, the geochemist and consultant, has found that the geology around Tuba City is "highly unlikely" to host uranium deposits, meaning it doesn't form there naturally.

Instead, he's also found evidence linking the radioactive plume in the dump to the chemicals used in the milling process at the Rare Metals mill.

"We've got fingerprints and good, solid data," Walker said.

But the person the EPA has assigned to work on this site, Carl Warren, isn't convinced the radioactive plume poses a threat to human health.

Nor is Warren certain there's any connection between what's in the radioactive dump and the uranium that was processed at Rare Metals.

Neither is the Department of Energy -- the agency usually responsible for cleaning up radioactive waste left over from wartime weapons production.

"The DOE did not find any evidence that would support the allegations that Rare Metals Corporation disposed of contaminated equipment or uranium mill tailings at the Tuba City landfill," it said in a letter to Shirley. " ... DOE believes that the ground water contamination discussed in your letter is not from the former mill site but is from the Tuba City landfill or some other nearby source."

Giving up the springs

The villages of upper Moenkopi and lower Moencopi live differently, but share the same water sources that naturally flow out of the ground.

Upper Moenkopi has electricity and running water inside the homes.

Lower Moencopi has electricity in a few homes. The stone and mortar houses lack plumbing because the traditional property owners elect not to install most utilities.

Lower village residents get water by going outside to a handful of faucets hooked up to gravity-loaded pipes fed by springs.

On a sandy road in the upper village, a metal pipe sticks out of a hillside spring, "Susungva," under a large tree. It pours clear, cold water into a basin of stone, next to a valley where Hopi farmers plant their fields every year. It's common to stop here and take a mouthful straight from the pipe.

"Even those that have running water in their homes, they still like to drink that spring water," said Chiropractor Alan Numkena, the lieutenant governor of Upper Moenkopi.

Upper Moenkopi has drilled wells to tap the deeper Coconino Aquifer as an alternative water source, but the villages need a $1.4 million reverse osmosis treatment system to make the water potable due to salinity.

There's no funding to pay for the treatment system, said Wilbert Honahni Sr., an economic development specialist with the Moenkopi Developers Corporation, a non-profit. And in a village where two to three families sometimes share a house, there are many other competing financial priorities.

There are going to be house-to-house surveys, interviews about the dump and public meetings for these residents in the months to come. Every fact must be documented in the political attempt to gain funds, excavate the contaminants of the dump and pump out the radioactive plume.

More test wells are pending near the dump, to see how far the uranium contamination has traveled. The village drinking water will be tested routinely.

"We tell them," said Hartway, the attorney for the Hopi Tribe, "that we will do whatever we can to know exactly what is in their water."

Spero News | Nuclear hypocrisy and Iran

Nuclear hypocrisy and Iran

Dick Cheney is right -- a nuclear-armed Iran is not a pleasant prospect, and we have to do something. But the most effective option is the hardest to swallow.

Article Tools
The Bush administration is very focused these days on Iran’s nuclear program. This focus has only sharpened in the aftermath of the International Atomic Energy Agency’s recent report that Iran continues to enrich uranium in defiance of a UN Security Council demand.

“A nuclear-armed Iran is not a very pleasant prospect for anybody to think about,” Vice President Dick Cheney told ABC News’ Jonathan Karl in Australia. “It clearly could do significant damage. And so I think we need to continue to do everything we can to make certain they don't achieve that objective.” Asked if the administration would continue to pursue diplomacy, the vice president responded that while “we've been working with the EU and going through the United Nations with sanctions… the President has also made it clear that we haven't taken any options off the table.”

In the White House, “options on the table” is code for military action. There have been many media reports of U.S. preparations to attack Iran. But the primary rationale for such an attack – to prevent Iran from going nuclear – is deeply problematic. Not only is the United States beefing up its military in general, it is even planning a modernization of its nuclear arsenal. The nuclear hypocrisy of the Bush administration makes any resolution of the conflict with Iran all the more difficult.

U.S. Military Spending

The new round of hand-wringing and saber-rattling about Iran’s nascent but worrisome nuclear program comes just a few weeks after the Bush administration announced its new budget, which included billions for nuclear weapons development. The Department of Energy’s “weapons activities” budget request totals $6.4 billion, a drop in the bucket compared to the Pentagon’s $481.4 billion proposed budget. But the budget for new nukes is large and growing -- even in comparison to Cold War figures.

During the Cold War, spending on nuclear weapons averaged $4.2 billion a year (in current dollars). Almost two decades after the nuclear animosity between the two great superpowers ended, the United States is spending one-and-a-half times the Cold War average on nuclear weapons.

In 2001, the weapons-activities budget of the Department of Energy (DOE), which oversees the nuclear weapons complex through the National Nuclear Security Administration (NNSA), totaled $5.19 billion. Since President Bush’s January 2002 “Nuclear Posture Review” asserted the urgent need for a “revitalized nuclear weapons complex” -- “to design, develop, manufacture, and certify new warheads in response to new national requirements; and maintain readiness to resume underground testing” -- there has been more than a billion-dollar jump in nuclear spending. Included in the $6.4 billion 2008 request is money for “design concept testing” of two new nuclear warhead designs that officials hope will be deployed on submarine-launched intercontinental ballistic missiles-- even as U.S. warships set their helms towards the Strait of Hormuz to menace Iran back from the nuclear brink.

Costly, Illegal, and Dangerous

Key to revitalizing nuclear weapons is Complex 2030, the NNSA’a “infrastructure planning scenario for a nuclear weapons complex able to meet the threats of the 21st century.” It is a costly, illegal, and dangerous program aimed at rebuilding the 50-year-old nuclear facilities where the weapons are both assembled and disassembled.

How Costly? The DOE estimates that Complex 2030 would require a capital investment of $150 billion. But the Government Accountability Office says that is way too low to fund even the basic maintenance of the eight nuclear facilities currently operational throughout the country.

Why Illegal? Complex 2030 promises a return to the Cold War cycle of design, development, and production of nuclear weapons, runs the risk of a return to underground nuclear testing, and could require the annual manufacture of hundreds of new plutonium pits -- the fissile “heart” of a nuclear weapon. These plans directly contradict U.S. treaty promises in 1968 “to negotiate toward general and complete disarmament.”

How Dangerous? Every step the United States takes away from the international consensus on the illegality and immorality of nuclear weapons is a new incentive and justification for other nations to pursue and brandish nuclear weapons. In a 2006 report, the independent “Weapons of Mass Destruction” Commission estimated the dark likelihood of ten new nuclear powers within a decade. At the end of January, the Bulletin of the Atomic Scientists advanced the hand of its Doomsday clock to five minutes to nuclear midnight, in part as a result of “renewed U.S. emphasis on the military utility of nuclear weapons.”

As the United States surges forward in its nuclear renaissance, the threat of nuclear terrorism and accidental nuclear strikes remains a grave yet under-funded priority. The administration occasionally raises the specter of nuclear-armed terrorists. In February 2004, for example, President Bush warned, “In the hands of terrorists, weapons of mass destruction would be a first resort.” Despite its rhetoric, however, the administration has done nothing to accelerate efforts to destroy and safeguard loose nuclear weapons and bomb-making materials, allocating about $1 billion a year to these crucial non-proliferation efforts (roughly the same amount that the Bush administration has been burning through each day in Iraq). At this rate, it will be 13 years before Russian nuclear material is secured.

The contradictions between what the administration is demanding of Tehran and other powers, and the capabilities it is pursuing for its own arsenal, are provocative and dangerous -- a pernicious form of nuclear hypocrisy.

Dick Cheney is right -- a nuclear-armed Iran is not a pleasant prospect, and we have to do something. But the most effective option is the hardest to swallow. Under the Nuclear Non-Proliferation Treaty, the United States agreed to an “unequivocal undertaking” to “eliminate” its nuclear weapons arsenal. Honoring that commitment -- and encouraging other declared and undeclared nuclear states to do the same -- would undercut Tehran’s arguments about why nuclear firepower is necessary. Oh, and by the way, it would also make the world feel a whole lot safer.
