Yes. GP is literally saying that 1-2 million gallons of water is a pretty small number not meaningful to anything at scale.
It's basically like framing power consumption in watt hours. A million watt hours is tiny at any scale, your whole neighborhood uses millions every day.
Please compare 1 million gallons to the 1 quadrillion gallons in the aquifer, or the 31 trillion that falls from sky each year in Nebraska and get back to me.
