As recently as December 2007, construction areas outside Orlando, Florida discovered UXO in new development areas and had to halt construction efforts. Other areas nearby, including UXO in the Indian River Lagoon thought to be left from live bombing runs performed during World War II by pilots from nearby DeLand Naval Air Station, have long been avoided by local boaters for fear of accidentally striking UXO as they motor by.
According to US Environmental Protection Agency documents released in late 2002, UXO at 16,000 domestic inactive military ranges within the United States pose an "imminent and substantial" public health risk and could require the largest environmental cleanup ever, at a cost of at least US$14 billion. Some individual ranges cover 500 square miles (1,300 km2), and, taken together, the ranges comprise an area the size of Florida.
In addition to the obvious danger of explosion, buried UXO also entails the risk of environmental contamination. In some heavily used military training areas, munitions-related chemicals such as explosives and perchlorate (a component of pyrotechnics and rocket fuel) can enter soil and groundwater. A prominent example exists at the Massachusetts Military Reservation (MMR) on Cape Cod, Massachusetts (USA), where decades of artillery training has contaminated the only drinking water for thousands of surrounding residents. An expensive UXO recovery effort is under way there.
UXO on US military bases has also caused problems for transferring and restoring Base Realignment and Closure (BRAC) land. The Environmental Protection Agency's efforts to commercialize former munitions testing grounds are complicated by UXO, making investments and development risky.
UXO cleanup in the US involves over 10 million acres (40,000 km2) of land and 1,400 different sites. Estimated cleanup costs are tens of billions of dollars. It costs roughly $1,000 to demolish a UXO on site. Other costs include surveying and mapping, removing vegetation from the site, transportation, and personnel to manually detect UXOs with metal detectors. Searching for UXOs is tedious work and often 100 holes are dug to every 1 UXO found. Other methods of finding UXOs include digital geophysics detection with land and airborne systems.
During World War I, the US Chemical Corps was established at American University, based in the University's McKinley Building. After the war, many toxic chemicals and weaponry were buried in or around the Northwest DC community where American is located. Excavations in the area are ongoing after significant discoveries were made in 2010.
Although comparatively rare, unexploded ordnance from the American Civil War is still occasionally found and is still deadly 150 years later. In 2008, for example, Civil War enthusiast Sam White was killed when a naval shell he was attempting to disarm exploded

Famous quotes related to united states:
“The men the American people admire most extravagantly are the most daring liars; the men they detest most violently are those who try to tell them the truth. A Galileo could no more be elected President of the United States than he could be elected Pope of Rome. Both posts are reserved for men favored by God with an extraordinary genius for swathing the bitter facts of life in bandages of soft illusion.”
—H.L. (Henry Lewis)
“America—rather, the United States—seems to me to be the Jew among the nations. It is resourceful, adaptable, maligned, envied, feared, imposed upon. It is warm-hearted, overfriendly; quick-witted, lavish, colorful; given to extravagant speech and gestures; its people are travelers and wanderers by nature, moving, shifting, restless; swarming in Fords, in ocean liners; craving entertainment; volatile. The schnuckle among the nations of the world.”
—Edna Ferber (1887–1968)
“What lies behind facts like these: that so recently one could not have said Scott was not perfect without earning at least sorrowful disapproval; that a year after the Gang of Four were perfect, they were villains; that in the fifties in the United States a nothing-man called McCarthy was able to intimidate and terrorise sane and sensible people, but that in the sixties young people summoned before similar committees simply laughed.”
—Doris Lessing (b. 1919)
“What makes the United States government, on the whole, more tolerable—I mean for us lucky white men—is the fact that there is so much less of government with us.... But in Canada you are reminded of the government every day. It parades itself before you. It is not content to be the servant, but will be the master; and every day it goes out to the Plains of Abraham or to the Champs de Mars and exhibits itself and toots.”
—Henry David Thoreau (1817–1862)
“A sincere and steadfast co-operation in promoting such a reconstruction of our political system as would provide for the permanent liberty and happiness of the United States.”
—James Madison (1751–1836)
