Many information sources were used to develop this issue of the Arroyo, which summarizes Arizona's current water situation, future challenges, and options for closing the looming water demand-supply gap.
The first numerical groundwater flow model of the Pinal AMA was developed by the Arizona Department of Water Resources (ADWR) in 1990. This report documents an extensive update of the 1990 model.
Please see the attached responses to Groundwater Modeling Workgroup action items GW-75, GW- 76, GW-77, GW80 and GW-81 for your review and consideration.
Pinto Valley Mining Corp. submitted a mining plan of operations proposing to expand mining operations onto National Forest System lands to access mineralization that extends onto claims on National Forest System lands, to extend the mine life for approximately 19 years, to address existing Open Pit slope instability in the southeastern portion of the pit, and to consolidate prior authorizations that are reasonably incident to extraction, transportation, and processing of mineral deposits.
