I agree, in principle...and, if it is simply ripped lava with little or
no soil on top, the water leaves the land pretty directly downwards
through the rip zone and into the mostly ever-present cracks and
fissures and tubes and chambers and so on.  It's a very porous place...
:-)  

Plantings over the whole area would probably have best chance to uptake
some.  There's far less chance (than most other situations I can think
of) that plantings on (for example) the lower boundaries of the
property will ever touch (to clean) any of the water that infiltrates
uphill of them.
