Why Did It Take So Long?

The Japanese government is going to step in and help at Fukushima, though specifically how is uncertain.

Estimated 75,000 gallons of contaminated water per day leaking into ocean, but activity concentrations not provided.

"The plan calls for freezing the soil around the buildings to shut off the flow of contamination into nearby groundwater, and thus end the leaks into the sea. Doing this would require an ice wall nearly a mile in length that would reach almost 100 feet, or 30 meters, into the ground. Officials said that an ice wall of such a scale had never been attempted before, making it unlikely that Tepco could pull off the feat alone."
