New Contaminated Water Leak At Daiichi Came From Same Tanks

A rise in contaminated water in the “C” drainage channel up on the hill was detected around Thursday. TEPCO has now admitted that water in the weir area of the H4 tank area may be to blame. A small leak in the pipe penetrations of the weir caused a leak of about 25 liters of water. TEPCO had been transferring standing water between the H6 and H4 weirs. They noted an unusual rise in the water of the H4 weir and later determined it was filling by natural siphon between the two weirs.

TEPCO now considers the leak of contaminated water from the two tank groups to be the cause of the newest rise in contamination at the drainage canal. The H4 tank group was the cause of a massive radioactive water leak over a year ago that caused considerable alarm when it was realized that it had leaked out to sea.

Photos below show the tank groups with the drainage canal as the solid white line running left to right below the tanks. The second image shows the connecting systems between the tank groups where the leak is said to have happened.
