July 16 marks likely worst - and most forgotten - US nuclear accident

On July 16, 1979, just 14 weeks after the Three Mile Island reactor accident, and just 34 years to the day after the Trinity atomic test, the small community of Church Rock, New Mexico, became the scene of another nuclear tragedy.

Ninety million gallons of liquid radioactive waste, and eleven hundred tons of solid mill wastes, burst through a broken dam wall at the Church Rock uranium mill facility, creating a flood of deadly effluents that permanently contaminated the Rio Puerco river.
