Alan Fryar's interests broadly cover hydrogeology and environmental geochemistry. Areas of emphasis include delineating rates and sources of groundwater recharge and discharge; interactions of groundwater and surface water; chemical evolution during groundwater recharge and flow; and natural attenuation of contaminants. Research projects with students have included controls on the composition of groundwater in regional sedimentary aquifers, such as within the Bengal basin of India and the Texas High Plains; sediment and pathogen transport during storm flow through karst aquifers in the Inner Bluegrass region of central Kentucky; groundwater flow to streams in the Gulf Coastal Plain of western Kentucky; and the fate of trichloroethene, a common solvent and suspected carcinogen, in geologic media. These projects have been supported by the Kentucky Department for Environmental Protection, the U.S. Department of Energy, and the U.S. Geological Survey as well as by UK. Student research typically includes a combination of field work, laboratory analyses, and mathematical modeling, and involves collaboration with other researchers at UK and elsewhere. Students commonly take courses not only in Geological Sciences, but also in related fields, such as Biosystems and Agricultural Engineering, Civil Engineering, Geography, and Plant and Soil Science. Former students have found work with consulting firms, with government agencies, and as university and high school teachers.
