We exports huge amounts of grain. The groundwater we're depleting isn't for our own use, it's to feed other countries.

Which is why it is a federal issue since the federal government controls interstate trade. Thus it’s accurate to say that America is depleting its aquifers. Which is the point of my response to you.

That you think states control their own water suggests you don’t understand the issue. For instance, one state can’t just put a dam on river and declare all of the water theirs and not allow distribution of it to other states.
