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]
