Or equivalently "Graduate students are being exploited."
(Addendum: Even if this is possible, if there is a source of radiation strong enough for that anywhere near inhabited areas, you probably have bigger issues than a little tritium in the water.)
unless you assumed the sewage was somehow radioactive
I was going to say that even that should be removed by distillation, and the water molecules shouldn't become radioactive, but now I'm not sure. Deuterium can capture neutrons to form radioactive tritium, but Wikipedia doesn't say if regular hydrogen can do the same to form deuterium.
This reminds me of Asimov's short story "Strikebreaker", where a person becomes untouchable by pressing the button for a remote-controlled waste treatment plant.
Since you need to treat sewage before putting it in the ground, and ground water before putting it in the water supply, what is new about connecting those two points? Do people think the sewage magically stops being sewage once it leaves the system?
I'd wager a guess a free country would be anywhere in the US outside of the 100-mile constitution-free zone around the borders
This also includes the coastline and international airports. So, maybe the interior of Alaska is free.
