Suffice it to say that it's probably a fairly high number if you take it over seven years and 23,000 substances. If you could get back to me on that, I would be very much interested.
I have a follow-up question. There are 4,000 substances now to be analyzed, and the departments, working together, are going to be analyzing that. What's your estimate of what the cost is going to be to the federal government to analyze those 4,000 substances?
