The process of updating the Pinal model geology was begun in 2007, and had not been addressed since Modeling Report No. 2 (Corkhill and Hill, 1990). The purpose of this provisional report is to document the data collection activities and findings of the hydrogeologic framework of the study area. This report will be finalized after the Pinal Active Management Area (AMA) Regional Groundwater Flow Model report which documents the update and recalibration of the groundwater flow model in Pinal County have been completed.

Groundwater monitoring in the upper Queen Creek and Devils Canyon watersheds was initiated by RCM in early 2004. The current RCM groundwater monitoring program includes 19 wells, boreholes or shafts. Based on results of hydrogeological characterization studies conducted to date, three principal aquifers have been identified. The purpose of the groundwater monitoring program is to provide hydrologic data for continued development and refinement of the conceptual hydrogeologic model for the ALT aquifer and adjacent aquifers in the study area that might be impacted by block-c
This report summarizes the meteorological, nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), and particulate matter (PM) data collected at the Resolution Copper Project near Superior, Arizona for the first quarter, January 1-March 31, 2013.
An investigation of hydrogeologic conditions for the Superior Basin has been completed by Montgomery. The chief objective of the survey was to evaluate the cause of recent water level declines reported for some wells located within and adjacent to the Queen Creek corridor through the Superior Basin, as well as observed declines in discharge from Whitlow Ranch Dam.
