quote:
In February, the EPA issued a safety standard that any amount of perchlorate less than 24.5 parts per billion in drinking water was safe. That was much higher than the 6 parts per billion California set as a public health goal, and higher still than EPA's original draft standard of 1 part per billion, a proposal environmentalists embraced. From what I remember of other news accounts, the danger posed by perchlorate is not well understood and remains an open issue in the scientific and medical community. This is why settling on a safety standard has been so difficult. And will make any lawsuit difficult.
