The humid weather is resulting in "sweaty" cold water pipes in our
basement.
I have read the suggestion to insulate the pipes just like with hot
water pipes. However, I am concerned that while this may reduce the
sweating, there still will be some condensation, but now the
condensation will be trapped against the pipe.
Should I be worrying about this? If so, what should I do to minimize
the potential for mildew and mold in this trapped moisture?
Second, I find that the condensation only occurs on the first few feet
of pipe in from the grounde. Is it possible that conduction causes the
water in the first few feet of pipe to stay cold all the time leading
to heavy condensation while beyond that the water for the most part
has warmed up (except when the water is actively running) so that
there is much less active condensation?

Pawlowski is, again, correct.
The water on the pipe surface comes from the air.
Thus, a well sealed insulation jacket will not allow moisture to fomr
on the pipe.

And it may increase the water heating bill.

Not in any measurable way. I assume you are meaning the heat the cold
water picks up in the line while waiting for some draw. It is minimum.
Even a few degrees rise in a pipe run of 40 ft doesn't add up to a
sneeze.
