Dive Summary:

• Problems at the Fukushima nuclear plant in Japan are far from over. On Wednesday, Japan’s Prime Minister Shinzo Abe urged the Tokyo Electric Power Co. (TEPCO) to handle the plant’s massive leak, which has been spewing out tons of toxic water into the ocean everyday for the past two years since the plant’s meltdown in March 2011.
• A makeshift barrier TEPCO made to block toxic underground water from entering the ocean has failed. Meanwhile, the utility has delayed public notice of the myriad problems.
• "For the next two to three years, I think water management would be their biggest challenge," Dale Klein, a former U.S. Nuclear Regulatory Commission chairman overseeing TEPCO's reform committees, told CBS. "But there will be more surprises," such as power outages, leaks and other unknowns, he said.

From the article:

“While the extent of sea contamination remains unknown, TEPCO has estimated that up to 40 trillion becquerels of radioactive tritium, a water soluble element that can affect DNA but is believed to be less dangerous than cesium or strontium, might have leaked into the sea over the past two years.”
