Is that water still there? Maybe underground?

I think so. 

The age of the deposit is strongly indicated by the thickness of the layer of ordinary red-brown, wind-blown dust deposited on top of it.  Laying down a deposit that thick would take only a few thousand years. If the silica depositing water trickled up from below (more likely in my opinion, because the silicate rich soil isn't everywhere in that area, as it would be if given a chance to weather away), it could be even younger than that.
