Following up on Neal's suggestion; you tape the square of plastic to the concrete wall. Tape all four sides.

Thanks nealtw and slownsteady. The vapor does appear on the backside of the plastic. So it seems to come from the outside. Do you think that maybe I should open that area and let it dry out? Is this a common occurrence?

Water does not usually leak thru solid concrete but it will wick thru it from cold to warm.
