Welcome to the Environmental Hydrology Laboratory (EHL), a research unit within the Soil and Water Science Department at the University of Florida.

The EHL promotes teaching, research, and outreach activities related to hydrologic processes. The motivation of the EHL is grounded in the sustainability of water resources. We emphasize both water security for human use and protection of natural systems. We support minimizing and remediating human impacts on hydrologic ecosystems.

Our teaching and research is focused in three major areas:

  (1) sustainability of water resources for urban and agricultural users,
  (2) coupled hydrologic and biogeochemical cycles in wetlands and watersheds, and
  (3) protection of groundwater quality, including remediation of contaminated sites.
