<br />Graham County Cooperative Extension, Jome Burge, Safford Agricultural
<br />Center.
<br />This project involves the modification and use of a mobile
<br />trailer, to bring water education to K -12 students in Graham,
<br />Greenlee and northern Cochise counties. Students will rotate
<br />through hands -on experiments at four stations focusing on the
<br />water cycle, watershed education, groundwater dynamics, and water
<br />chemistry /biology housed in a specially designed mobile laboratory.
<br />As the first of its kind in the state, the vehicle will deliver water edu-
<br />cation to rural areas and serve as a prototype for use in other coun-
<br />ties across Arizona.
<br />"Unless we manage water as a precious resource,
<br />using the most advanced scientific research to assure
<br />water quality and water supply, all other efforts to
<br />develop aglobally competitive economy in Arizona
<br />will come to naught. " UA President Peter Likins
<br />Mountain Block Recharge and the Hydrology of Caves: An Interactive Dis-
<br />play .$18,620. Susan Pater, Cocbise County Cooperative Extension; Kim
<br />McReynolds, Area Agent, Natural Resources
<br />Interactive displays, a touch - screen kiosk and an animated
<br />web site will be developed, produced and maintained to increase
<br />hydrologic literacy of the general public at Kartchner Caverns. The
<br />Caverns is the state's newest and most popular state park that draws
<br />200,000+ visitors a year. Understanding mountain block recharge,
<br />the hydrology of caves, the hydrology of the nearby San Pedro Riv-
<br />er, and the importance of groundwater will lead to greater public
<br />awareness of water resource concerns and the need for conserva-
<br />tion.
<br />Know Your Water: Manual of WaterQuakiy and Treatment for the Home
<br />Owner, x$37,075. Dr. Janick Artiola, Dept. of Soil, Water and Environmen-
<br />tal Science; Dr. Kathryn Farrell -Poe, Dept. of Agricultural and Biosystems
<br />Engineering.
<br />A handbook of water quality parameters, water quality stan-
<br />dards and home treatment options will be produced for the general
<br />public to assist them in making informed decisions about the need
<br />and use of potentially costly home water treatment. An electronic
<br />version will also be available for direct web access.
<br />Destructive Treatment of Halogenated, Semmolatile Solvents in Soil- Vapour
<br />Extraction Gases. ,$24,500. Dr. Eduardo S/eZ, Dr. James Baygents, Dept.
<br />of Chemical and Environmental Engineering; Dr. Brian Barbaris, Superfund
<br />Basic Research Program; Dr. J. Brent Hiskey, Dept. of Materials Science and
<br />Engineering Dr. Eric Betterton, Dept. of Atmospheric Science.
<br />This project will examine and implement a cost - effective al-
<br />ternative technique for field scale treatment of sites contaminated
<br />with hazardous semivolatile chlorinated solvents. Trichloroethylene
<br />(TCE) and perchloroethene (PCE) are primary contaminants of
<br />dozens of hazardous waste sites in Arizona. The removal of these
<br />solvents from soil vapor extraction gases from the vadose zone will
<br />be explored using a gas diffusion membrane - electrode assembly
<br />obtained from a modified fuel cell. The contaminants will be con-
<br />verted to non - halogenated, nontoxic products.
<br />Antibiotic - Resistant Bacteria and Endotoxins in Association with Land Ap-
<br />plication of Biosolids: Possible Impact on Quality of Groundwater Supplies
<br />and Comparison to Other Routes of Work- Related and Household Exposure.
<br />,F55,660. Dr. Patricia Rusin, Dr. Chris Rensing, Dept. of Soil, Water and
<br />Environmental Science.
<br />Research will determine whether antibiotic - resistant bacteria
<br />and endotoxins in biosolids used as an agricultural land amend-
<br />ment act as a significant source of contamination to Arizona water
<br />resources or pose a risk to public health. Evaluation of the relative
<br />health risk of antibiotic- resistant bacteria and endotoxins from bio-
<br />solid application compared to other common routes of exposure,
<br />the impact on groundwater, and transfer of antibiotic resistance
<br />genes to soil and groundwater bacteria will be explored. This will
<br />be pertinent information for the biosolids industry, regulatory agen-
<br />cies and the community as use of this soil amendment continues to
<br />increase.
<br />Quantifying Mountain Front Recharge in Southeastern Arizona. $52,620.
<br />Dr. James Hogan, Dr. Brenda EkwurZel, Dept. of Hydrology and Water
<br />Resources.
<br />Quantification of natural recharge and improved conceptual
<br />understanding of natural recharge rates are crucial for developing
<br />water resources management strategies and establishing and main-
<br />taining riparian conservation goals. Isotopic tracers will be used to
<br />investigate mountain front recharge, which is an important if not
<br />dominant recharge pathway for alluvial basin aquifers in Arizona.
<br />Water resources managers will be able to use the information gen-
<br />erated to better quantify natural replenishment rates and have an
<br />improved understanding of how climate, vegetation change and
<br />development might impact recharge rates.
<br />Integrated Water Education Implementation in the Classroom. ,$58,140. Dr.
<br />Lisa Elfring, Dept. of Biochemistry & Molecular Biophysics; Dr. Elizabeth
<br />Hancock, Dr. Jean Morrill, Dept. of Hydrology and Water Resources.
<br />Water resource kits for classroom use based on critical themes
<br />(i.e. water quality, watershed processes) will be developed and sup-
<br />plied to teachers, with specific training, to enable effective delivery
<br />of quality water education. Course material will be integrated into
<br />the existing curriculum. Classroom support will be provided by
<br />graduate students trained to function as water education specialists.
<br />Increased understanding of water science and improved instruction
<br />in science and math are anticipated. Over a three year period it is
<br />projected that there will be thousands of face contacts with these
<br />new resource materials.
<br />Development of Riparian Evapotranspiration and Ecohydrologic Models
<br />to Predict Changes in and Consequences of Riparian Water Availability.
<br />,$69,510. Dr. Thomas Maddock III, Dr. James Sbuttleworth, Dept. of Hy-
<br />drology and Water Resources, Dr. Travis Huxman, Dept. of Ecology and
<br />Evolutionary Biology.
<br />This project will lead to the completion of a new groundwater
<br />model for evapotranspiration (ET), and refinement of an ecohydo-
<br />logic model to predict the hydrological and ecological changes in,
<br />and consequences bf, riparian zone water availability. Products of
