Yes, Micrococcus can be pathogenic, but I'd sooner think the person who 
sampled the well was sloppy (I hope it wasn't you :) ).  Micrococcus are 
among the most widespread airborne contaminants Š they're everywhere 
just blowing around.  As far as disease causing, they would be 
opportunistic, ie., affecting an already sick person or immune 
suppressed person.  I'd have the water check again.  The lab the did the 
testing may be dusty and the Micrococcus may be from them, not your 
water.  Also, beware if they have a vested interest ($$$) in you 
deciding to flush your system.
