Tepco to start purifying waste water on 15th

Not the highly radioactive water they dumped into the sea...

http://www.wsws.org/articles/2011/apr2011/japa-a06.shtml

From the article:

"Some of the most dangerous water has already seeped from the plant,
although it remains unclear how much. That water, thought to be coming from
reactor 2, is giving off radioactivity of 1,000 millisieverts an hour. Just
15 minutes exposure to this water would result in emergency workers at
Daiichi reaching their permitted annual limit of 250 millisieverts."

We only have Tepco's word as to how much highly radioactive water was
released into the sea. As it turns out, all of the information we received
early on greatly downplayed the seriousness of the situation. Who would be
surprised if we found out tomorrow that the amounts Tepco have released
into the sea were triple or quadruple the amounts reported up to now and
that additional information has been withheld?

Who would be surprised to find that the initial quake and follow up quakes
initiated 'Liquefaction' http://www.youtube.com/watch?v=ODTu3cZ2AVs
underneath the area housing the reactor cores and caused their
rupture in the first place? Who really knows how much water has been
contaminated as a potential result?

Where would all of that potential radioactive water go? What would it contaminate?
What would be the ramifications for soil, water and air, from that potential contamination?

What valuable information would 'airplane analogies' tell us about such
potential repercussions?
