Results of Hydrochemical Characterization of Groundwater Upper Queen Creek/Devils Canyon Study Area

In February 2010, Montgomery published a report entitled "Interim Results of Groundwater Monitoring, Upper Queen Creek and Devils Canyon Watersheds" (M&A 2010) which reported all hydrochemical and isotopic data available through the second quarter of 2009. The current report presents hydrochemical and isotopic data collected since M&A 2010 was published.
