Kristen Uhlman

 Kristine Uhlman, RG, is retired following 42 years in hydro-geology, including her most recent positions with the University of Texas at Austin and Texas A&M where she authored the Texas Well Owner’s Guide to Water Supply.  At UT Austin she was part of a research team investigating the impact of hydraulic fracking for the enhancement of oil/gas development on drinking water aquifers and earthquake development.  Prior to that she was at the University of Arizona, Water Resources Research Center for nine years where she developed a state-wide educational outreach program on water resources and watershed planning. Under a grant with the Arizona Department of Environment, she and her team modeled every watershed in the state of Arizona and published a series of watershed planning documents.  With the University she published the Arizona Well Owner’s Guide to Water Supply.  

With a degree in Hydrology from the University of Arizona (1974) and a Masters in Civil Engineering from the Ohio State (1975) Ms. Uhlman started her career with the United States Geological Survey and then worked with various consulting firms throughout the United States and internationally.  Her work included the investigation of several ‘Superfund’ sites and the construction of numerical models to design groundwater clean-up systems, as well as expert witness testimony on environmental sites under litigation for damage to drinking water aquifers. Ms. Uhlman has extensive experience in groundwater resource management and protection.  Her aquifer characterization experience includes subsurface exploration in many geologic settings, including the arid regions of the Middle East and the Southwestern United States, glacial outwash aquifers, fractured bedrock, karst, and coastal areas susceptible to salt-water intrusion. Project experience includes geologic data acquisition and analysis; project management; aquifer characterization; environmental site remediation and compliance; aquifer vulnerability assessment; groundwater modeling; and, expert witness testimony. Prior to retirement she was appointed to the position of Executive Editor of the journal Ground Water.  Ms. Uhlman is a frequent speaker to the public, local and state government, and scientific conferences on groundwater quality issues and tools/information necessary to improve groundwater resource management.

Ashley Hullinger

Ashley Hullinger is a Research Analyst at the University of Arizona Water Resources Research Center. She manages the Water RAPIDS Program (Water Research and Planning Innovations for Dryland Systems) based at the WRRC in Tucson and extending through several counties in Arizona. Much of Ms. Hullinger’s work revolves around developing effective and down-to-earth tools to understand complex water resources situations and promote sustainable water management throughout Arizona, especially in rural watersheds. As part of the Cooperative Extension, she works directly with communities looking at issues that span beyond physical water resources to consider the people and history that have contributed to current conditions. She assisted and led research to develop a water budget, future water scenarios, and other watershed resources in the Upper Gila River Watershed, specifically in Graham and Greenlee Counties, which informs her current efforts in the Globe-Miami area and Pinal County.

Ms. Hullinger holds a M.S. in Urban Planning, with a concentration in Water Resources, from the University of Arizona and B.A. degrees in History and Geography from the University of Kansas.
