In a development that will surprise absolutely no one, the Environmental Protection Agency (EPA) declined to protect the nation's drinking water supply from contamination by the chemical ammonium perchlorate.

Don't expect to see a limit put on this stuff anytime soon, either. The reason? I'm willing to bet it has something to do with the fact that both NASA and the Department of Defense routinely dispose of the substance - used in both rocket fuel and the manufacture of munitions - by diluting it and dumping it on the ground.

The EPA argues that percholate has been found in less than one percent of American water supplies. One percent may not seem like much, but it still represents more than 150 municipal drinking supplies. And when you factor in that the substance has been linked to incidence of thyroid problems in both children and pregnant women, even one percent seems like too much.

Once again, when push comes to shove, you can always bet on the engines of government bureaucracy to put their own interests and needs before that of the public - even when it comes to the issue of dangerous chemicals in the drinking supply.
