Geologist with a bit of a background in hydrogeology here:Thanks to all who answered. The reason for my question is that I moved from an area that is relatively arid but fracking is occurring. Many people are complaining that the water used as a base for fracking is gone forever from the earth's water recycling system. I don't know how much water is used but the amount is small enough that is brought to the site in trucks so in the grand scheme of things is not that much. Also some is recaptured and reprocessed and/or reused. Therefore it is obvious that there is not a net loss but a net gain of water to the earth's system because much more water is gained by the burning of the fuels made from the oil produced as well as the natural gas the by products such as propane. Many more gallons of oil comes out of the ground than water is injected, if it were not the case there would be no economic incentive to do it, and each gallon of oil causes an increase of about one gallon of water even though it is the form of water vapor for the time being. At some point that water vapor becomes liquid water. The extra water and carbon dioxide encourages the growth of plants particularly in arid regions and tends to balance the system.
Please actually try reading my posts before you comment. You're embarassing yourself.California has real stupid water rules.
Interesting in one post we are told it takes for ever to recharge ground water, and in the next, if it rains lots the ground does not sink.
Aquifers cover large areas. Pumping water for a golf coarse, may be from the same aquifer. I am not familiar with California and can not wait for it to crack off and take all the crazy people with it towards Hawaii. Or better yet they vote to leave.
You're purposely twisting my words into what you want them to be. Yes, years with heavier rains will have more recharge, but it's small compared to the amount being pumped. The recharge by itself would not be enough to stop the subsidence. It's the reduced pumping.Your Quote. "Years with heavy rains and lots of surface water have far less subsidence since there is more aquifer recharge, and far less ground water pumping. Dry years see significant land subsidence."
I see Aquifer Recharge in your quote.
...and other states do not use as much water as California does. California's huge industry and immense agriculture has tremendous water demand. California produces 50% of the nations fruits and vegetables, and that requires a TON of water.Other states have little surface water. They have reasonable water rules.
