===Contamination===
It was revealed in 2007 that during the 1980s a contractor had dumped up to 1,000 pounds of [[urea]] at a pond on the TTR, resulting in the die-off of 61 horses in 1988.<ref>[http://www.lvrj.com/news/11783161.html CONTAMINATION PROBE: 61 horses died in '88 at test site], Las Vegas Review Journal, Nov. 24, 2007.</ref>  The fluid had been used as a de-icing agent.  The [[Bureau of Land Management]] investigated in November 1988, and imposed remedial actions and assessed a $15,000 fine.  In 2007 over concerns that the chemical was infiltrating groundwater, a whistleblower unsuccessfully attempted to get the [[United States Environmental Protection Agency|Environmental Protection Agency]] to intervene, leading to an August 2007 inquiry with the [[Department of the Interior]] by Senator [[Harry Reid]].
