If you have some "education about radioactive materials" you'd know that the half-life of tritium is 12.5years and that it is a beta emitter. This type of radiation isn't harmful unless ingested. You would also know that the water has been diluted to safe levels before being released in the ocean, and even after that dilution, it will also not be released all at once, further reducing the chance of re-concentration and making radiation poisoning impossible. Finally since this is tritium we are talking about it, it isn't a bio-accumlator and if you did drink too much tritated water, the treatment would be to drink an increased amount of tap water.

Since you are still just "asking questions," about how Tritrated water is "treated" it kind of sounds like you don't actually know about radioactive materials at all otherwise you would know about H3, i.e. tritium and wouldn't be concerned about "treatment" only the concentration of the released water.

Nuclear bad! Solar just around the corner! Ignore current emissions!
