Water issues of Rosemont copper mine

Water attorney Hugh Holob published in the Tucson Citizen a substantive piece on the ground water issues around the proposed Rosemont copper mine.

I was struck by the comparisons between Rosemont's planned water use and that of existing users.

Holub says Rosemont has an ADWR permit for up to 6,000 acre-feet per year which is about one-tenth the amount used by agriculture and mining in the Green Valley area currently. Golf courses in the area use about 4,500 acre-feet. [right, ground subsidence in Green Valley - Sahurita during the period 2-2007 to 3-2008, based on satellite interferometry. Credit, ADWR]

    what's your point?

  2. 1. There's an article online with some interesting comparisons of water use

    2. Existing water use is relatively large compared to what has been permitted by Rosemont

    3. There's measurable subsidence going on in the area likely due to groundwater withdrawal. What will be the impact of the Rosemont operation on groundwater?
