  Water infiltration and percolation at the University of Arizona radioactive waste burial site, Pinal County, Arizona

  Salvetti, Joseph Peter.; Dutt, Gordon R. (The University of Arizona., 1984)

  The University of Arizona produces different types of radioactively contaminated waste. It is shipped to a burial site located on the Oracle Agricultural Center in Pinal County, Arizona and disposed of in shallow pits. This study dealt with water movement at the disposal site. Monitoring of water movement through young pits was accomplished with a neutron probe. It was found that due to slumping and cracking of the pit cap, the younger pits were very susceptible to greater than normal water infiltration. Further data were gathered around the older pits by deep soil sampling for tritium activity. Water fluxes and travel times to the major aquifer were calculated from these data. Estimates of travel times range from 40 to 230,000 years to reach the principal aquifer at 150 m.

  The Archaeological Survey of the Northern Tucson 138 kV Transmission Line System: The Northern Tucson Basin and Lower Santa Cruz Valley, Arizona [No. 132]

  Rozen, Kenneth (Arizona State Museum, The University of Arizona (Tucson, AZ), 1979)

  In August 1978, an archaeological survey of the proposed Northern Tucson 138 kV Transmission Line System was conducted by the Cultural Resource Management Section of the Arizona State Museum, under the sponsorship of the Tucson Gas & Electric Company (TG&E). The rights-of-way of about 40 miles of existing and proposed transmission lines, extending from within the city of Tucson, Arizona, north to the vicinity of Red Rock, Arizona, and the site of the proposed Tortolita Substation were surveyed. Most of the region in which the transmission line system is located has not previously been subjected to archaeological investigation. As a result of the survey, eight areas of archaeological remains were identified; four were assigned Arizona State Museum site numbers. Two of the sites are interpreted as representing the remains of prehistoric agricultural activities, while one site is a historic trash dump; the significance of the prehistoric remains at the fourth site is uncertain. The four areas of archaeological materials that were not assigned site status include two sparse scatters of prehistoric artifacts, a sparse prehistoric and historic artifact scatter, and a small concentration of lithic artifacts that is interpreted as having been produced by the reduction of one or two cobbles. In addition, numerous isolated artifacts were found widely scattered along most of the transmission line rights-of-way. Included in this report are a description of the transmission line system facilities and of the methods by which they were surveyed. The environmental setting of the project area, including its physiography, climate, geology, flora, and fauna, is briefly discussed, and a review of its archaeological background presented. The archaeological remains discovered during the survey are described, and their significance briefly discussed. Recommendations for the management of the archaeological resources are provided, and an opinion given regarding their eligibility for inclusion in the National Register of Historic Places and the Arizona State Register of Historic Places.

  Hohokam Archaeology Along the Salt Gila Aqueduct Central Arizona Project - Volume IX: Synthesis and Conclusions [No. 150 Vol. 9]

  Teague, Lynn S.; Crown, Patricia L. (Arizona State Museum, The University of Arizona (Tucson, AZ), 1984)

  This volume is the last in a series of nine reporting the work of the Salt-Gila Aqueduct, Central Arizona Project Archaeological Data Collection Studies and Supplemental Class 3 Survey Project (SGA). This study was funded by the U.S. Bureau of Reclamation (Contract No. 0-07- 32-V0101) to mitigate potential adverse impacts of Central Arizona Project construction on cultural resources in the aqueduct right-of-way. Data recovery was conducted at 45 Hohokam sites along a 93 km (58 mile) transect extending from Apache Junction to a point southwest of Coolidge and near Picacho, Arizona (Fig. Intro. 1). This is the largest of the Central Arizona Project archaeological studies to date, although it may fall short of being the largest that will be conducted under the program. (excerpt from Introduction)
