Following up this article..

Extremely high density of Tritium was detected from groundwater of deep layer.

Tepco has started building the frozen water underground wall. In order to investigate the groundwater contamination outside of the wall, Tepco took sample from 25m underground.

As a result, 3,100,000 Bq/m3 of Tritium was measured from the sample taken near reactor2. The sampling date was 5/28/2014. From Fukushima Diary’s research, this is the highest reading since they started measuring.

They measured Strontium-90 from the same deep layer beside reactor4 last November.

There is a possibility that contaminated water is traveling under the sea bottom of Fukushima port to come up offshore.

From Tepco’s follow-up report on 6/13/2014, the Tritium density increased again and it reached 4,700,000 Bq/m3 in the same from the same sampling well (Location is on the map above).

Tepco hasn’t made any explanation on this increase in Tritium density. From Fukushima Diary’s research, this is the highest reading since Tepco started measuring groundwater 25m underground. There is a possibility that the frozen water wall is spreading contamination underground.
