contaminated sediment near storm drain outfalls. With dredging  
completed by spring, the sight of Americas Cup racing yachts arriving  
at their temporary dock in the lagoon seemed a harbinger of the  
approaching end of the Superfund era at the Point.

Just outside the Seaplane Lagoon, another dredging operation was  
started and finished at one of the maritime ship piers where the Cape  
Orlando had been docked. By November, the massive ship was back at  
dockside, hull lights glowing at night.

In one of the most complicated and contaminated areas east of the  
Seaplane Lagoon, cleanup work began at an area 30 feet below ground  
where a cleaning solvent used on aircraft parts had seeped into the  
groundwater. After driving a series of metal bars down to the  
contaminated area, the soil, groundwater, and solvent were heated to  
just below simmering by means of electricity. This turned the water  
and solvent into vapor, which was then vacuumed out into a filtering  
system through a series of pipes.
