Special Sapplaawvd <br />this work will have immediate and direct benefits to the San Pedro <br />River ecosystems and its stakeholders as well as region -wide ben- <br />efits. Conservation planners and regional water planners are seeking <br />tools to make informed decisions regarding effects of water alloca- <br />tion decisions on environmental amenities. <br />Occurrence and Control of Emerging Waterborne Pathogens in the State of <br />AH.Zona. ,$46,340. Dr. Charles Gerba, Dept. of Soil, Water and Environ- <br />mental Science. <br />The parasite Naegleria fowleri and the Norwalk virus are two <br />pathogens that have recently emerged as water quality problems in <br />Arizona. N. Fowleri in the water supply caused the death of two <br />young children in separate episodes in Peoria, and the Norwalk vi- <br />rus has caused illness among <br />visitors to Grand Canyon <br />National Park on river rafting <br />expeditions. The potential hu- <br />man exposure to N. Fowleri <br />from drinking water and ef- <br />fectiveness of current control <br />measures will be examined. <br />Sources and potential control <br />methods for N. Fowleri will <br />be investigated. The work <br />will provide much needed <br />information to public health departments, water departments, and <br />government agencies. <br />Quantifying Potential Endocrine Disruption in Effluent Dominated and Efflu- <br />ent Dependent Waters within Arizona: Fish as Habitat Assessment Biomark- <br />ers. ,$49,000. Dr. David Walker, Environmental Research Laboratory, Dept. <br />of Soil, Water and Environmental Scdencel Dept. of Wildlife and Fisheries <br />Science; Dr. Dennis McIntosh, Dept. of Soil, Water and Environmental Sil- <br />ence. <br />As population centers grow in Arizona so does the prevalence <br />of effluent dominated waters (EDW's) which are becoming increas- <br />ingly important as habitat for wildlife. These waters may contain <br />chemicals which can cause endocrine disruption in vertebrates, <br />often resulting in decreased fecundity at the population level. While <br />emerging technologies exist to rapidly analyze endocrine disruption <br />in EDW's, they often fail to address the long -term, chronic effects <br />of low -level exposure to these chemicals. In order to better under- <br />stand these effects, native species of fish will be grown in captivity <br />using water collected from EDW's throughout the state and their <br />blood and plasma levels analyzed for sex hormones and morpho- <br />logical abnormalities. This quantification will enhance the ecological <br />characterization of EDW's so that appropriate treatment technolo- <br />gies can be implemented to reduce any detrimental effect caused by <br />endocrine disrupting compounds. <br />Hydrologic and WaterQuality Modeling for Watershed Assessment and <br />Planning. ,$23,060. Dr. Pbill f Guertin, School of Renewable and Natural <br />Resources. <br />The project is to improve and expand the functionality of a <br />user - friendly decision support system (DSS) called the Automated <br />Geospatial Watershed Assessment (AGWA) tool. This is already an <br />effective tool for use by stakeholders to develop, understand and <br />S -3 <br />evaluate alternative watershed management strategies. Modifications <br />of the system would enable application for developing watershed - <br />based water quality plans that address non -point source pollution. <br />Arizona Water and Pesticide CD. ,$'19,110. Louis Carlo, Dr. Paul Baker, <br />Dept. of Entomology and Cooperative Extension. <br />The use and misuse of pesticides due to drift, over application, <br />and unsafe storage are leading to accumulating pesticide residues <br />in our waterways. The Arizona Water and Pesticide Safety CD is a <br />multimedia distance learning course that will explain the problem of <br />pesticides in our waterways and it will teach safety guidelines to pro- <br />tect community health and environmental quality. Plans include the <br />distribution of this multimedia distance learning course throughout <br />Arizona. This CD will strengthen outreach and education aimed at <br />providing a high- quality water supply and watershed environment in <br />Arizona. <br />Tailored Drought Planning forAtkona. ,$47,570. Dr. Greg Garfin, Institute <br />for the Study of Planet Earth; Dr. Barbara Morehouse, Institute for the Study <br />of Planet Earthl Dept. of Geography and Regional Development; Dr. An- <br />drew Cowrie, Dept. of Geography and Regional Development. <br />The recent drought and its differential impacts across the state <br />highlighted the lack of a statewide process for identifying and ad- <br />dressing water management stresses, particularly in rural areas. This <br />project, conducted in coordination with the Arizona Drought Task <br />Force, will include (1) analysis and synthesis of hydroclimatologi - <br />cal information on drought at temporal and spatial scales useful for <br />drought monitoring and decision making; (2) identification of local - <br />scale sensitivities and vulnerabilities to drought within Arizona; (3) <br />characterization of interactions among risk factors across different <br />levels from local to state to federal; and (4) education and outreach <br />emphasizing interpretation and use of scientific information, fore- <br />casts and related decision tools. <br />Estrogenic Activity in Reclaimed Water and Stormwater. ,$50,630. Dr. Rob - <br />ertArnold, Dept. of Chemical and Environmental Engineering Dr. David <br />Quanrud, Arid Lands Studies; Dr. Kevin Laney, Dept. of Civil Engineering <br />and Engineering Mechanics. <br />Arizona surface waters that are effluent dominated frequently <br />contain levels of estrogenic compounds that are known to pro- <br />duce developmental problems in continuously exposed fish.
