epa recommendations on safe levels of percholorate in water

I'm slow on this, but the Integrity of Science blog has a post about a special report in the Oregonian about the efforts of the White House and Pentagon to hinder the EPA's promulgation of recommendations for safe levels of perchlorate for water. The Pentagon's interests in this is that percholorate is a component of rocket fuel, and the Pentagon may wish to be shielded from cleanup costs.
