NHK WORLD, Aug, 26, 2013: [...] Workers are still unable to say when they will be able to stop the water from seeping into the ocean. In May, highly radioactive groundwater was detected in an observation well on the sea side of one of the reactor buildings. Levels of radioactive materials in nearby waters have since risen. The plant operator, Tokyo Electric Power Company has been trying to contain tainted groundwater from leaking into the ocean since the accident. [...] But all the attempts have been unsuccessful. In addition, the utility has yet to pinpoint the cause of the contaminated groundwater. TEPCO workers are struggling to remove the existing contaminated water from under the ground. There is also a need to monitor the arrival of large amounts of groundwater to prevent it from being contaminated. [...]
Salon, Aug. 23, 2013: [...] This week, alarming news has been pouring out of Japan’s Fukushima Daiichi nuclear power plant [...] As we’re now learning, more problems have been building beneath Fukushima’s surface, to a far greater extent than officials have been willing to acknowledge until now, when the severity of the situation has become impossible to ignore. [...] Beneath the surface, however, the situation was far from contained. [...] From the beginning, that contaminated water has been leaking. [...] For the past two and a half years, a “massive underground reservoir” of contaminated water has been building up underneath the plant. Tepco is widely alleged to have not done enough to contain it. The slow, seeping buildup of a second catastrophe came to a head this summer. [...] The underground reservoir has been climbing above barriers set to contain it, and experts now fear that it’s about to reach the Pacific Ocean. Amid frustration that Tepco could have done more to prevent this from happening are fears that it’s unprepared to handle the coming fallout. [...]
