Most of the fuel would evaporate before it hit the ground because of the fine dispersion of the droplets. Most of the evaporated fuel would not condense, but be broken down by various chemical reactions in the upper atmosphere.

If dumping occurs at the usual altitudes it's supposed to, it dissipates, but that's not necessarily the case down low. AA had a widebody takeoff a few years ago from DFW (heading north) and had a problem that necessitated an immediate return. They started dumping on the climbout, and some suburbs to the N-NW (Lewisville and Flower Mound) had neighborhoods where parked cars and other surfaces had a thin coating of fuel residue on them.
