Fukushima I Nuke Plant Groundwater Contamination: TEPCO's Ad-Hoc Underground Impermeable Wall in Embankment Made It Worse: As I called it

This is just too ... (I can't even come up with the right word to describe).

Amateurish, maybe. Pathetic, maybe. And sad.

Because radioactive materials started to get detected in June this year in observation holes along the embankment in orders they didn't expect, TEPCO hastily decided in early July to inject waterglass in the soil of the embankment to create an impermeable wall in the ground. Since it is hot during the day at the plant, they made the workers work at night in full protection gear, from 7PM to 7AM, in the area with high radiation.

According to the articles below, we now know what many of us may have been suspecting all along. The idiom "Haste makes waste" exists for TEPCO.

It turned out that injection of chemicals to create the impermeable wall was too successful. It not only stopped the flow of groundwater, but raised the groundwater level significantly. So now, the groundwater is probably going up and over the hastily built underground impermeable wall, and through the porous, top part of the embankment into the open culvert.
