Jiji Press, May 28, 2014: Tritium levels at Fukushima No. 1 well top Pacific dumping limit, Tepco admits […] The discovery was the first report of over the limit tritium in groundwater at the wells since Tepco began discharging water […] from one of the 12 wells on Monday, 1,700 becquerels per liter of tritium was detected, exceeding the maximum limit of 1,500 becquerels, the utility said on Tuesday. […] Tepco stopped pumping water from the well on Tuesday night, and said it plans to step up groundwater monitoring. The utility is now releasing groundwater from the 12 wells into the sea after temporarily storing it in tanks and checking radiation levels.

The Big Picture, May 27, 2014 (at 45:00 in): Radiation levels keep rising near Fukushima plant — “Radiation levels have spiked to an all-time high in the seawater surrounding Japan’s Fukushima nuclear power plant. Earlier this month Tepco announced they detected similar levels in groundwater at the plant. They say that the cause of the spike is still unknown. […] Tepco has proven that they are not capable of dealing with this massive problem. The situation at Fukushima has gotten worse, not better. It’s time for the international community to step in and prevent an even more serious disaster.”
