> Tritium is already present in the ocean

Would that be like saying "carbon dioxide is already present in the atmosphere"?

We've increased the atmosphere's CO2 concentration by 50%. A few grams of tritium won't significantly change its concentration in the ocean.

Is that true locally though?

There is sure a lot of water in the ocean, but it's still possible to poison stuff locally, wherever you drop the stuff is going to have higher concentration, at least for a short while.

Another commenter down the thread:

>The process for releasing typically dilutes to a standard level before releasing into the ocean/ other water way. So when it's released, it's already at a level you could swim in (drink?), there's no process for it accumulating into a more concentrated form in the ocean, and it has a half-life of 12 years.

It would be if we added way more tritium. We are adding a very small amount compared to what is already there naturally and even that will decay away.
