Jenn Hoyle Fair’s professional experience and academic research focus on the challenges of long-term protection of our drinking water supply. Her approach to water resource management has evolved from the more controlled confines of engineered treatment technologies and remediation programs to the broader and more complex problems of using land management strategies to protect water quality at the source. Hoyle’s primary professional goal is to contribute to the growth and establishment of watershed management as a primary means for protecting our drinking water supplies through study of how improved modeling and monitoring methodologies can better advise watershed management practices.

Fair’s undergraduate studies in membrane filtration at Yale led to water resource engineering positions at nationwide engineering/consulting firms. As both a water supply and a groundwater remediation engineer, she learned first-hand the ecological and financial cost of upstream contamination and downstream treatment. At F&ES as a master’s student Fair focused coursework on three areas: fluvial geomorphology, hydrologic and hydraulic modeling, and payments-for-watershed-services mechanisms that can incentive landowners to manage land for source water protection. After her first stint at F&ES she worked as a stream engineer writing basin-scale management plans and designing river restoration projects for the New York City Department of Environmental Protection, the water utility for New York City, which avoids expensive filtration of water supply via an aggressive watershed management program.

As a doctoral candidate at F&ES Fair continues to focus her research on improving mechanisms for surface water protection at the watershed-scale using hydrologic modeling tools. Fair uses complementary field measurement and modeling approaches to examine the manner in which streamflow frequency and duration interact with biogeochemical processes to affect the utilization and export of dissolved organic carbon from a large drainage network. 

Fair hopes that her doctoral work at F&ES will prepare her to re-enter the field of drinking water management with improved understanding and tools necessary to make basin-scale decisions on investment in natural treatment solutions for water supply protection. Her long-term goal is to contribute to solutions to contentious water resource management problems around the globe.
