Fukushima Leak Now an 'Emergency' Underground barriers not working, radioactive water now rising to ground level By Ruth Brown, Newser Staff Posted Aug 5, 2013 5:41 PM CDT 28 comments Comments Workers in protective suits and masks wait to enter the emergency operation center at the crippled Fukushima Dai-ichi nuclear power station.

Shinji Kinjo tells Reuters that TEPCO's "sense of crisis is weak" and the country can't rely on the power company alone to fix the problem. "Right now, we have an emergency," he says. The company built an underground shoreline barrier to keep the contaminated water from reaching the ocean, but Kinjo says it isn't working—it's just forcing the water over and under the barrier. "If you build a wall, of course the water is going to accumulate there. And there is no other way for the water to go but up or sideways and eventually lead to the ocean," says a former nuclear engineer. "So now, the question is how long do we have?" The Asahi Shimbun newspaper reports that the contaminated water could reach the ground's surface within three weeks. Once that happens, says Shinjo, "it would flow extremely fast."
