Seawater contamination - Fukushima brief update

And, again not very surprisingly, we've just seen our first hint of some of the site's geological setting with a reference in the Japanese media that TEPCO has indicated that there seems to be a permeable sandy layer underneath the levels of the pipe tunnels / cable tunnels ("trenches") at the Fukushima Daiichi site that may be permeated with contaminated water. A hint that some sort of further injection to either the piping or ground is intended today was given.
