Plane Down in Hudson River - NYC

fuel contamination

Now that we know this same a/c experienced a compressor stall in the right engine 2 days earlier....and that US Airways prefers a pilot to carry less than full fuel....would condensation be a factor? Could an engine go through a series of stalls from water contamination in the fuel and be damaged to the point that the damage is not noticed until tasked? Is a compressor stall so routine that they go unreported?
