Tepco finally admitted the “possibility” that contaminated water penetrated to the deep layer of the ground

Tepco finally admitted the possibility that contaminated water penetrated to the deep layer of the ground. Tepco announced in the extraordinary press conference of 6/24/2014.

Fukushima Diary has been pointing out the possibility for months.

(cf, Tritium density in deep underground broke the highest record ever, 4,700,000 Bq/m3 ) Tepco was stating that the contaminated water reached 15m underground, but it’s stopped by impermeable layer right underneath.

However 120,000 ~ 140,000 Bq/m3 of Tritium was measured 25m underground from the sample of 6/10/2014 as well. Tepco is still “under investigation” for the cause, but they are stating the construction of frozen water wall might have spread the contaminated water accidentally.

If the contaminated water is penetrating to deep layer of the ground, there are few measures to stop it spreading. It can also travel underground of the ocean bed to come up to the sea offshore of Fukushima plant.
