Permeability in metamorphic rock tends to be nonexistent, as this particular kind of rock, formed from cooling lava,  is quite dense.  However, where these rocks are fractured, some permeability may occur; even so, only a small amount of water may exist in the fissures.  In the US, however, these rocks extend over large areas, and curiously, large amounts of ground water can be extracted from them.
