There are several problems to be dealt with in regards to groundwater flow. These graphics will demonstrate some, but certainly not all, of the issues
to be faced:

J&C, no idea about the water wall, unfortunately. The literal meanings of the characters for "particles" in that picture are "grain-child," so it
is, unfortunately, a very broad term. When there are things not explicitly said but likely inferred, I promise I will make notes at the bottom to
convey as much as possible.
All that being said, Ｆｏｒ this next image, do you have any more context than what I could translate? Only because there's a character that could
mean "tearing/severing/breaking" (as in the earth) or "analysis" (as in the document). It changes the meaning of the image considerably and
there's really not enough context for me to say definitely what it is, one way or the other.
I'm on a roll... if anyone wants anything else translated. Again, it's not native, but hopefully a bit more informative than Google
From this post Aircooled in the mega thread
and further analyzed in
this post by me in the same thread,
The Geology of Fukushima (direct link to 1.21 MB pdf)
The good news is that the radioactive water leaking from the plant will not be able to spread towards the Japanese inland and the Abukuma plateau
due to the downward slope of the geological layers. The bad news is that there exists a fault which appears to be active right under the Fukushima
Daiichi plant itself: this allows, and will continue to allow, radioactive pollution of aquifers over a depth of several hundreds of meters, as it
runs through the different "waterproof" strata (4). This also means that the radionuclides will naturally be carried towards the sea by this
underground water stream flowing through the permeable layers of sandstone. Sandstone is indeed the ideal rock for aquifers, as it is both permeable
and fractured, providing easy movement of water. And finally, there is the problem of the type of rock on which the plant was built being rather
"soft", meaning that an earthquake can only destabilize the buildings.
As early as March 31, 2011, Tepco announced that the groundwater was contaminated with radioactive iodine, according to an analysis of a sample
taken at a depth of 15 meters under the first reactor (link ). Today, if one or more coriums have sunk into the ground, this pollution has very likely
been increasing. But Tepco no longer shares any information about the pollution of groundwater. Their only concern is to present a beautiful
reassuring façade, which will never solve this disastrous pollution of soil and groundwater: underground contamination is irreparable, because there
is no access to it.
This has been going on for over two years now.
I'd like to make note of the reference to methane gas in regards to reactor 3 that seems to traverse into reactor 4, is it possible that the
earthquake disrupted a pocket of methane beneath the site that seeped into R3 and thence into R4 building to explosive levels and that it was a
methane explosion that destroyed reactor 4 rather than a hydrogen explosion?
I don't think hydrogen would do the damage that is obvious in reactor 4.
We'd have to know the volume of the building to be able to determine the explosive potential present if methane were to reach the proper air/fuel
ratio and then be able to match that to the damage as presented in the pictures. No video has ever surfaced of reactor 4's explosion, that I know of.
Redneck, do you really think that the coriums have completely ablated the concrete basemats of the foundations and are now open in the environment
below the reactor buildings? And, if so, how deep do you think they have dug?
