Fracking won’t affect water level much


In most of the media, I’ve been seeing a lot about how much water it takes to frack a well. The figure I see most is 2 million gallons of water per well.

Let’s see if I can put this in perspective. When we were farming we had three irrigation wells pumping a total of 3,000 gallons of water per minute—every six hours a million gallons. So 12 hours for 2 million gallons, and in 24 hours enough water to frack two wells.

What about Marion Reservoir? One acre foot of water is enough water to cover one acre one foot deep. Three acre feet is 1 million gallons, and six acre feet is 2 million gallons, enough to frack one well.

At normal level, Marion Reservoir is 6,100 acres. Take six acre feet per well, that is enough water to frack 1,000 wells to lower the water level one foot if you could pump it out in 30 minutes. Water for 100 wells would lower the water level 1.2 inches, or 10 wells 0.012 inches.

I don’t think that would have much effect on either the water in the reservoir or ground water tables. When Marion County gets 1,000 fracked wells, that will be a lot of oil.
