|Contamination from test firing ranges
What are the health effects?Persistent fears among residents
The main purpose of DU shells is to destroy tanks made of heavy metals. Test firing of DU shells from tanks requires a large firing range; aerial bombing practice from airplanes requires huge desert bases.
Changing perceptions of the government
Unfortunately, the permissible area happens to lie entirely within a national desert wildlife preserve. DU rounds have been test-fired here since the early 1970s, because radioactivity and heavy metal pollution were not considered serious problems until the mid 1980s. However, a US Congress decision required the Air Force to find 44,500 hectares (about 170 sq. miles) for a wildlife preserve in another part of the state to compensate for the land it contaminated in this area.
Grace Potorti (45) =pictured=, executive director of the NGO Rural Alliance for Military Accountability based in Reno, Nevada, explains the change in attitude of the state residents and state government as follows.
"Nevada cooperated with atmospheric nuclear tests at the Nevada Nuclear Testing Site since the beginning of the 1950s. Until the mid-1980s, it welcomed every expansion of military presence. Then things changed. Though the military presence was doing wonders for the economy, the people and the state government began to realize that the damage to the eco-system and the health of the residents from the use of DU and other munitions surpassed the benefits.
1.5 million unexploded shellsThrough the Internet, the Alliance exchanges information with grassroots groups located near military bases all around the country. According to Potorti, the great majority of DU firing ranges are located in sparsely populated areas and are embroiled in controversy regarding radioactive contamination.
One of these is the Army's Jefferson Proving Ground (JPG) in southeast Indiana. To demonstrate the power and accuracy of DU rounds, test firings were repeatedly carried out over 22,300 hectares (about 85 sq. miles) between the mid-80s to 1994. The legacy is about 70 tons of DU, shell fragments, and contaminated storage buildings.
Since 1941, JPG has been test-firing various other kinds of weaponry as well-about 1.5 million unexploded rounds were simply abandoned there.
Tremendous clean-up costsThe Department of Defense has decided to close JPG, but closing and returning the base to the state of Indiana requires decontamination. An environmental report on JPG by researchers at the Los Alamos National Laboratory (New Mexico) in 1996 estimated that a total of $7.8 billion would be needed to clean up the DU alone.
Faced with such a mind-boggling figure, the cleanup has bogged down. Until it takes place, wild deer and other animals living in the vicinity of the radiation-contaminated base will absorb depleted uranium through the air and food.
Area residents have long hunted deer for food and pleasure. People who eat that venison will absorb depleted uranium concentrated by the food chain. They can buy safe drinking water, but they cannot escape the dangers of raising cattle, other livestock and crops on contaminated water.
Though the Department of Defense assures the residents that contamination on the base will not affect their health, Potorti says, "People around here are very worried."
Moreover, as seen in communities living near the firing range of the Energetic Materials Research Test Center attached to the New Mexico Institute of Mining and Technology in Socorro, New Mexico, and the Sierra Army Depot in Herlong, California, the historic homes of native American tribes are being contaminated, and health problems are emerging.
