Los Alamos National Lab, America's premier nuclear weapons research and development facility/factory, seemed to weather the Las Conchas wildfire without a major nuclear incident (e.g. the potential threat of fire releasing dangerous levels of radiation in to the air from various Material Disposal Areas or lab facilities). A new threat exists now, but this time from flash floods potentially washing contaminated soil in to the Rio Grande river, the source of drinking water for many New Mexico communities including the capital Sante Fe.  According to a July 11, 2011 article by Reuters:
...In a recent PressTV interview (below), Willem Malten of the Los Alamos Study Group states "there is a frantic community effort under way with mainly Native Americans sandbagging their own homelands while the [The Los Alamos National] Laboratory just removed 12,000 cubic yards of contaminated soil from the canyons."
The soil in the canyons above Los Alamos National Laboratory, the linchpin of American's nuclear weapons industry, contains materials with trace amounts of radiation and hazardous chemicals such as polychlorinated biphenyls (PCBs) that were dumped there decades ago, said Fred deSousa, spokesman for the lab's environmental control division.
Over the weekend, about 1,200 cubic yards of contaminated soil was removed primarily from two canyons -- Los Alamos and Pajarito -- that run through lab property, deSousa said.
The erosion control effort, which included the installation of 600 feet of water diversion barriers, will continue this week, he said.
PressTV: 'Monsoon rain could flood Los Alamos with contaminants'
Some key points were raised in the interview. Approximately 4 minutes in to the interview Malten states that a year long Associated Press investigation has found that the NRC (Nuclear Regulator Commission) has allowed aging nuclear power plants to run beyond their natural lifespan by relaxing previously set safety standards. Also of note is the segment of the interview starting at 7 minutes 7 seconds. Here Malten says that there has been "too cozy of a relationship between the nuclear industry, regulators and politicians for too long." The Obama administration received $210,000 in campaign contributions from the nuclear industry according to Malten.
