Dullness Ring around faucett & soap dispenser

My specific problem is that we recently had installed "Black Impala" granite
countertops.  In just a few weeks we developed dulling or cloudiness
surrounding, approx. 1/2 inch around, the sink faucett and more, approx. 1
inch, around the soap dispenser.  The soap dispenser was a litlle loose and
I figure that water from countertop wipe ups might have been sliding down
the drill holes and getting into the granite from the raw inside of the
drill holes.  Perhaps our somewhat hard Connecticut well water is causing
the dullness.  Is this a stain?  Can you fix it from the surface?  How?  Any
help/advice will be appreciated.

Thanks,
