It is common to hear things like it takes one gallon of water to create a single almond, or watering a lawn can take X gallons per month/year, or it takes X gallons to make one pound of beef or yield X pounds of alfalfa.

My question is, is that water “gone forever”? Or does the water thats used return to the water table/cycle in some other form. When you water the lawn does a large amount of that seep into the ground, evaporate, and return to the atmosphere?

Or is the water used in these ways truly gone forever (in terms of humans being able to use it again)?

    Sometimes it becomes toxic. Sometimes it’s relocated to a different watershed. The only time it is removed is when it’s split into O2 and H2, but the oxygen tends to stick around, and the hydrogen will soon reunite with oxygen
