Meridiani Drying Up?

When the original news of Opportunity's watery finds at Merdiani were announced in early 2004 .. we had a region of Mars that to quote NASA was "drenched in water" with long standing pools or lakes on the surface.

However, the most recent science results all refer to "ground water" rather than surface water producing the concretions etc. It also seems that much of the bedrock making up the walls of Endurance Crater... and Victoria Crater are vast "fossilised" dune fields - not very watery at all. Is the story of water at Merdiani drying up?
