"In some agricultural and metropolitan areas, eastern Arkansas and central Utah for example, the water resources are literally being mined. Taken out of the ground at a rate faster than they can ever be replenished. Some of it is fossil water, laid down in geological epochs far in the past, which can never be replaced. In the rice and soybean fields of eastern AR, the farmers have to pump from deeper and deeper depths as the water surface drops. And when this happens, the aquifer often compacts from the pressure of the overburden of earth, reducing its capacity to accept any new water, even if any is available. To date, the water in an aquifer can only be replaced by rainfall in an area it can reach the aquifer by soaking into the earth. Perhaps the only other possibility is the desalinization of sea water, which will likely be possible only when new energy sources become very, very cheap. Note that Texas has a coastline, and a possible future resource. If Oklahoma water is going to be sold to Texas, the contract had better be year-to-year, contingent upon excess supply being replaced by rainfall. Or Oklahoma will regret it, and possibly end up buying water from Texas in the future."
