That's an interesting, read, thanks for sharing! For what it's worth, the study used massively higher doses of tritium than what's being released: 10 million becquerels/L in the study water (which is 1,000x the drinking water limit) compared with - per Reuters - 63 becquerels/L in the wastewater.

I stopped short of saying that I didn't think there would be environmental harm because it does seem like there's cause for concern, even if the tritium has a relatively short half life. But I don't know if the claims being made by opponents are justified.
