TEPCO's been struggling to keep Fukushima's scorching reactors cool. They've also been struggling to deal with the massive volume of (now radioactive) coolant water. It's not going so well—tons of it are spilling into the ground, Reuters reports.
The leak's a consequence of TEPCO's botched attempts to purify contaminated water held in giant storage containers—an effort that's been marred by mechanical screw-ups and delays. And now, the realization that 15 metric tons of it have already seeped into the ground around the plant, filling the soil with radioactive isotopes. [Reuters]
