Matthew D. LaPlante of The Salt Lake Tribune found that the U.S. Army made several errors in its attempts to dispose of Utah's stockpile of lewisite, a now-illegal agent similar to mustard gas used in chemical warfare. Lewisite can be disposed of in two ways: by incineration, which can release arsenic into the air without the right filters; or by neutralization, a process supported by most environmental groups, which disposes of the chemical by dissolving its components in hot water. After building a multi-million dollar plant to neutralize the chemical, the Army incorrectly found that the neutralization process was ineffective and tore down the plant a few years later.
Now many are balking at the Army's plans to build a properly-filtered incineration plant in the same area. The Healthy Environment Alliance of Utah is calling for the Army to rebuild the neutralization plant, which they see as a safer practice.
Looks like you haven't made a choice yet.
