In our professional evaluation of modeling requirements for the proposed 20-year Rosemont water supply, we determined the ADWR Tucson Active Management Area (TAMA) model is the best option for simulating regional groundwater level changes caused by proposed groundwater withdrawals. The model was developed by the U.S. Geological Survey and ADWR for the purpose of simulating groundwater level changes in the TAMA. Hydrogeologic conditions in the TAMA, including aquifer parameters and hydrogeologic units, have been substantially investigated and incorporated into the model over the almost 40-year development period of the model, resulting in the current calibrated regional model we selected to project effects of proposed Rosemont pumping.
