The Wall Street Journal printed an article today on the Arsenic issue, which I recommend you read. The regulation which Mr. Bush cancelled was under consideration for seventeen years before being put into effect. "Dozens of studies" were conducted. The margin of safety for Arsenic (in federal regulations) "is lower than for virtually any other substance the EPA regulates." On the other hand, it is expensive to get rid of, so that very large outfits like ARCO (which runs Anaconda Copper) hired people to prove that Arsenic really isn't dangerous. And then suppressed the studies when the results showed that yes, it really was that dangerous. The article mentions three additional instances where scientists were misquoted, or bribery was attempted, in an effort to make it appear that Arsenic really wasn't all that bad.
So with this background, our President now tells us, that Clinton made a decision "at the very last minute," which he, George W. Bush, "pulled back," "so that we can make a decision based on sound science."
All this is in today's WSJ. I read it every day, and in my opinion the WSJ is not infected by any liberal bias.
