What happened there?

I think that it was just human error.

I mean, we're talking about, as you know, when you get into policy issues, you get into... painful acronyms, terminology that doesn't always make sense.

And, you know, sometimes you probably need a special degree just to understand one particular policy issue.

And so I think state officials misread what the requirements said, put out the wrong number.

And, you know, I think that led to the confusion.

Now, I think it's important to note, you know, even though we're talking about what maybe seems like a small difference, zero to 15 percent, You know, I think it's important to remember, number one, obviously lead, the health professionals are clear, lead is unsafe at any level and it's harmful at very small levels.

What's the difference?
