Modeling of Lead Concentrations and Hot Spots at General Aviation Airports

I'm pleased that a paper I contributed to just got published:

Transportation Research Record, the Journal of the Transportation Research Board, No. 2569, p. 80-87, "Modeling of Lead Concentrations and Hot Spots at General Aviation Airports", by Stephen N. Feinberg, Jeremy G. Heiken, Marc P. Valdez, Jim M. Lyons, and Jay R. Turner.

I'm surprised the modeling worked out as well as it did. So easy to make difficult-to-detect errors with this intricate stuff.
