SpeclaG supplement
<br />S -4
<br />is designed to monitor Arizona effluent - dominated streams for
<br />whole -water estrogenic activity using a variety of in vitro bioassays,
<br />examine treatment and polishing methods that can remove estro-
<br />gens from wastewater and establish levels of estrogenic activity in
<br />stormwater runoff. Water resource managers need this information
<br />to regulate water reuse practices safely and efficiently in Arizona.
<br />Detection of Noncytoptbogenic and Treatment Resistant Human Virus Popu-
<br />lations in Drinking Water Using Integrated Cell Culture /PCR. $53,630.
<br />Dr. Kelly Reynolds, Environmental Research Laboratory, Dept. of Soil, Wa-
<br />ter and Environmental Science.
<br />Contamination of surface water resources by human viruses is
<br />causing considerable concern due to their small size and long -term
<br />survival that make them less likely to be removed by treatment pro-
<br />cesses. A rapid and reliable method for the evaluation of drinking
<br />and reuse water supplies and disinfectant efficacy for the elimina-
<br />tion of a variety of human pathogenic viruses in drinking water will
<br />be developed by this work.
<br />Improved Turf and Landscape Irrigation Management for Northern Arizona.
<br />$48,020. Dr. Paul Brown, Dept. of Soil, Water and Environmental Science;
<br />Dr. Peter Waller, Dept. of Agricultural and Biosystems Engineering.
<br />The objective of this project is to improve the efficiency of
<br />landscape irrigation in Northern Arizona by developing a multi-
<br />faceted educational program. Specific aspects of the program will
<br />include the development of: 1) publications that describe and en-
<br />courage proper landscape irrigation management in high elevation
<br />areas; 2) a website to disseminate project information; 3) irrigation
<br />demonstration projects; 4) annual landscape irrigation workshops
<br />in Payson, Flagstaff, and Prescott; and 5) a small network of au-
<br />tomated weather stations that will improve irrigation management
<br />by providing accurate estimates of evaporative demand in Payson,
<br />Flagstaff, and Prescott.
<br />Educational Workshops and Feasibility Study for Sustainable Forage Pro-
<br />duction on the Havasupai Reservation. $17,215. Dr. Edward Martin, Dr.
<br />Donald Slack, Dept. of Agricultural and Biosystems Engineering• Elisabeth
<br />Didier, Assistant Agent, Agriculture Natural Resources, Mojave County.
<br />Adjacent to a remote corner of Grand Canyon National Park,
<br />the Havasupai Reservation is accessible only by helicopter, pack ani-
<br />mal or foot, with food and supplies imported into the community.
<br />A feasibility study to investigate the possibility of restarting agricul-
<br />ture coordinated with educational workshops on water conserva-
<br />tion, water quality, irrigation practices and crop production would
<br />help the tribe become more sustainable. Effluent and creek water
<br />are available water resources. Utilizing the waste water will have the
<br />dual benefit of using a resource that already exists in the village and
<br />reducing the loading of waste ponds which are a potential source of
<br />health problems when rains flood the village and lead to contamina-
<br />tion of Havasu Creek.
<br />Simulated Basin Model for Water Resource Planning and Education.
<br />$108,680. Dr. Kevin Laney, Dept. of Civil Engineering and Engineer-
<br />ing Mechanics; Dr. Paul Blowers, Dr. Wendell Ela, Dept. of Chemical and
<br />Environmental Engineering Dr. Paul Brooks, Dr. Steven Stewart, Dept. of
<br />Hydrology and Water Resources; Dr. Paul Wilson, Dept. of Agricultural and
<br />Resource Economics
<br />A valuable interactive tool to improve water resources manage-
<br />ment decisions will be provided by developing an integrated deci-
<br />sion support simulation model. Understanding the impact of alter-
<br />native management options, including identification of new water
<br />sources, conservation measures, water reclamation and water treat-
<br />ment on a cost effective basis will be possible for both technical and
<br />non - technical constituents. Selection and evaluation of alternative
<br />management plans for specific locations will be possible by tailoring
<br />the general model with local information. In addition to identifying
<br />solutions for water managers and policy makers, the model will be
<br />critical in educating the public and generating acceptance of water
<br />plans.
<br />The Evaluation of Paleo Data to Determine Past, Present and Future Hydro-
<br />logic Variability in Arizona. $53,820. Dr. Victor Baker, Dept. of Hydrol-
<br />ogy and Water Resources; Dr. Jeffrg Dean, Dr. David Meko, Dr. Ronald
<br />Towner, Laboratory of Tree -Ring Research; Dr. Juan Valdes, Dept. of Civil
<br />Engineering and Engineering Mechanics
<br />It is critically important that agency planners, land managers,
<br />politicians, public interest groups and the general public understand
<br />past hydrologic variability, the frequency and severity of extreme
<br />events, and the probabilities of their incidence in order to make
<br />more informed decisions concerning the management of Arizona's
<br />water resources. The proposed paleohydrological research, along
<br />with historical records and paleoclimatic data, will be assembled
<br />into a database to enable assessment of hydrologic trends. The
<br />resulting increased accuracy for prediction of return periods for
<br />floods and droughts, plus the more accurate characterization and
<br />forecasting of drought periods, will have a tremendous impact on
<br />water policy and management.
