    in fracking is from aquifers and as such is not renewable in the sense of other renewables.

    •  The majority of aquifers are recharged by ongoing (0+ / 0-)

      processes; mainly percolation of precipitation. Only some -- mainly in areas where today's climate is now drier than it was in the past -- are not at least partly recharged today.

      The effect of hydrofracturing on potable water aquifers is something that should be studied by the U.S. Geological Survey and the states, in concert with EPA. Whether it will or not is another question.

      That said, this article is about a pipeline; not about hydrofracturing.

      for example the Oglala in the midwest. yes, aquifers re-charge eventually, but it's usually on GEOLOGIC time scales (thousands, millions of years).
