  • TEPCO is currently in talks with local authorities about releasing the groundwater. (rt.com)
  • But the water buildup continues, and the short-term storage tanks that TEPCO has been relying on in the past are no longer a solution, so the operator is to set up a bypass system to prevent further buildup of the other, highly radioactive groundwater. (rt.com)
  • Radioactive materials persist in the soil and groundwater, and leftover waste from the reactor trickles from leaky underground tanks. (sciencehistory.org)
