I just posted the article that the head of Fukushima's fisheries associations has agreed to the government/TEPCO plan of "groundwater bypass".
However, there are two problems.
First, the drains near the H4 area where the leaking RO (reverse osmosis) waste water tank is located are general-use drains, and they go out to the ocean OUTSIDE the plant port, as I show in the black arrow in the upper right corner in the map below:
So far, the water in the drains have little radioactive materials, and no radioactive materials have been detected in the seawater in the south of the plant, according to the Nuclear Regulatory Authority in the August 21, 2013 meeting.
The second, and far more serious problem, I think, is that the location of the H4 area with at least one leaky tank is JUST TOO CLOSE to the 12 wells that TEPCO has dug for the groundwater bypass plan, to intercept and draw uncontaminated groundwater before it hits the reactor buildings.
