OverviewAI-generated summary
Phillip D. Hays' research focuses on hydrology and water quality, with an emphasis on understanding the interactions between surface water and groundwater in Arkansas. His work investigates the impacts of agricultural operations, such as swine slurry holding ponds, on local water quality. Hays also studies the influence of land use and human activities, including highway construction, on stream chemistry and groundwater systems. His research has examined the potentiometric surfaces and water-level changes in key aquifers within Arkansas, contributing to a better understanding of regional hydrogeology. He has published 68 papers and has been cited 1,050 times, with an h-index of 13. Hays collaborates with researchers at the University of Arkansas at Fayetteville.
