So what’s the conclusion as to what’s happening?

As I wrote about in a thread a couple weeks back (here, here, and here), this should have been fine, and was fine on paper.

According to official statements it was going to be diluted, before release, to a level that was even lower than what Fukushima NPP put out while operational. Then it was going to be released at a rate that maintained this concentration.

Did Japan lie? Did it not dilute how it said it would? Was it a technical failure and dilution did not occur at the level they said it would, or was it released too fast at the dilution level they set? Was there not testing at release time/site?
