The GRS readings suggest the water is subsurface.

See this:

Earth, Wind and Fire: What's Missing?
"In the map of hydrogen abundance from orbit, Gusev shows a high hydrogen abundance. The hydrogen abundance at Gusev and Meridiani are similar to that closer to the poles (~50% latitude) and could represent between 20-50% of subsurface H2O within one meter of the surface.
This is particularly intriguing because Gusev and Terra Meridiani (the destination for the companion Opportunity rover) are positioned as one of only several equatorial areas with high hydrogen compositions."
