How much water does it take to grow a hamburger?

Pretty much everything we eat needs water to either grow or create. This water is either supplied by nature as precipitation or added by man during the growing/production process. You can't tell by the size or texture of a food how much water was actually used to produce the food item. To grow that hamburger, for example, it takes water to grow the vegetation the cow eats, water for the cow to drink, water for processing the meat, maybe even water for a cow bath! It all adds up.

Hamburger (1/4 pound): Your answer: 0 gallons | Correct answer: Not so easy to answer this, but there are a number of estimates:

Thirty years ago, the Water Education Foundation offered up an answer of 1,300 gallons,

and in an additional study in 1991 came up with another estimate of about 620 gallons.

The California Beef Council sponsored a study that produced a number of just over 100 gallons,

though that number excludes rainwater.
