  • Evaluating the Effectiveness of the Casa del Agua Water Conservation Demonstration Tour in Promoting Water Conservation Behaviors

    France, Glenn; Office of Arid Land Studies, University of Arizona, Tucson, AZ 85719 (Arizona-Nevada Academy of Science, 1989-04-15)
    A typical single family residence in Tucson, Arizona (Casa del Agua) was retrofitted with water conserving devices, graywater and rainwater recycling systems, and a low water use landscape. An educational tour designed to promote the incorporation of these water saving techniques has been ongoing at the home since December, 1985. A questionnaire survey was administered between April and July 1988 to determine the extent of water conservation behavior, demonstrated by the adoption of the water conservation techniques, of the Pima County population and the tour participants. Both population samples exhibited similar water conservation behaviors. It was also determined, from the analysis of the survey results, that the tour led to additional water conservation technique adoption.
  • Water Conservation Potential Research at Casa del Agua

    Foster, Kennith E.; Karpiscak, Martin M.; Office of Arid Land Studies, University of Arizona, Tucson, AZ 85719 (Arizona-Nevada Academy of Science, 1989-04-15)
    Casa del Agua is a research and demonstration project to test the efficiency and liveability of a house that has been relandscaped and redesigned with water saving and recycling devices. Ongoing research focuses on six interrelated tasks: 1) water quality and sampling to characterize graywater and rainwater and to determine their potential to impact the environment; 2) water balance analysis that quantifies fresh water use, graywater production and use, and rooftop runoff and use; 3) evaluation of system components that could enhance graywater reuse; and 4) maintenance and modification of existing systems. An interpretation of recent data and information derived from the performance of the above tasks indicates the effectiveness of the project's water-saving strategies, as well as other significant findings relevant to water conservation in an urban, residential setting.
  • A Planning Process for Water Supply Development

    Olson, Steven L.; Arizona Department of Water Resources, Tucson A M A, Tucson, Arizona 85701 (Arizona-Nevada Academy of Science, 1989-04-15)
    Arizona's Groundwater Management Act has changed the perspective that water providers must use when planning to meet growing water demands. The goal of safe-yield in the Active Management Areas and the requirements of both the Second Management Plan and the Assured Water Supply provisions will require all water providers to consider other options besides additional groundwater development when expanding their water supply plans. A simplified process will be presented that stresses the need for well thought-out, cost-effective water resource planning to meet management requirements for both public and private water providers. The process relies on an initial projection of water demand, an analysis of demand reduction potential, an examination of supply alternatives, and a discussion of the characteristics that must be considered when weighing the demand reduction and supply alternatives for implementation. Development of water supply plans that meet existing and future needs for growing service areas will be increasingly important to water providers in Arizona and throughout the and West.

  • Organic Contaminants in Urban Lake Sediments: A Preliminary Assessment

    Amalfi, Frederick A.; Sommerfeld, Milton R.; Department of Botany, Arizona State University, Tempe, Arizona 85287 (Arizona-Nevada Academy of Science, 1989-04-15)
    Bottom sediments from several urban lakes located in the Phoenix metropolitan area were collected and analyzed for organic priority pollutants. The lakes selected for analysis were broadly representative of the diversity of lake characteristics found in the Phoenix area. That is, lakes were sampled that had different types of primary water sources and that were located in watersheds of differing degrees of urbanization. Preliminary results indicate that only nine of the 114 listed organic priority pollutants were found in measurable quantities in the sediments of the lakes surveyed. The pollutants detected were either phthalate esters or volatile or semi-volatile halogenated compounds. None of the pollutants were common to all the lakes sampled. Dibutyl phthalate was detected in three of the six lakes. A larger database is being developed and will be necessary to determine whether a statistical correlation exists between watershed characteristics and feedwater, and organic composition of lake sediments.
  • Perils of Progress - Hydrogeological Hazards in Las Vegas Valley, Clark County, Nevada

    Katzer, Terry; Brothers, Kay; Department of Research, Las Vegas Valley Water District, Las Vegas, NV 89153 (Arizona-Nevada Academy of Science, 1989-04-15)
    The prehistoric Indian population in Las Vegas Valley found abundant water for their needs from springs flowing from the base of numerous fault scarps throughout the valley. The faults are generally considered to be compaction faults caused in part by subsidence resulting from dewatering aquifers as the climate became dry and warm during the interglacial periods of the Pleistocene. The valley's aquifers, for historical purposes, eventually reached steady state conditions which lasted through nearly the first half of this century. Urban growth then created a demand for water that was satisfied by overdrafting the ground-water system, which reactivated subsidence. Today, subsidence effects cover about 1,000-1,300 km² of the valley and the maximum vertical displacement is about 1.5 m. As the demand for water continued to increase with population, large imports from the Colorado River via Lake Mead provided abundant water, which helped create additional hazards: a rising shallow water table, resulting from over irrigating landscapes (secondary recharge), intersects land surface in places in the central and eastern part of the valley creating a hazard to structures and facilities; the potential increases in liquefaction; and, the potential for degradation of the deep aquifers from downward percolation of the poorer quality water from the shallow system.
  • Water Quality of Streamflow from Selected Forested Watersheds in Arizona
