2013 Water in the Landscape Distinguished Seminar Series

Flint River in Georgia 

Field and Watershed Scale Research on Onsite Wastewater Systems
Tuesday, March 19, 2013, 1:30-2:30 pm
McCarty Hall (D G001)

The Center for Landscape Conservation and Ecology and the UF Soil & Water Science Department present Dr. David Radcliffe, Professor in the Deparment of Crop and Soil Science at the University of Georgia. Dr. Radcliffe will speak on "Field and Watershed Scale Research on Onsite Wastewater Systems".

In the Southeastern states, more than 40% of the homes use onsite wastewater treatment systems (OWTSs) or septic systems to dispose off household wastewater. Properly functioning OWTSs offer several advantages over centralized wastewater treatment facilities, including reduced construction and maintenance costs, elimination of sanitary sewer overflows and leaks, and recharge of water resources. On the other hand, OWTSs have been reported as the source of nitrogen (N) in groundwater and streams in a number of studies.

This presentation will highlight results from two studies conducted in Georgia:

  1. a field-scale study that was completed in 2012 where an OWTS was installed, monitored, and modeled to determine the fate of N, and
  2. a watershed-scale study that is underway where the impact of OWTS on stream flow and water quality is being determined in 24 small watersheds in metro Atlanta.

The Speaker

Dr. David Radcliffe, University of GeorgiaDr. David Radcliffe is currently a Professor in Crop and Soil Science Department at the University of Georgia. His research focus is on water movement and nutrient and sediment transport in agricultural systems and onsite wastewater systems at the field and watershed scale using field measurements and modeling studies. Dr. Radcliffe served as Associate Editor and Technical Editor of Soil Science Society of America Journal. He is a fellow of the Soil Science Society of America (2004) and has received Soil and Water Conservation Merit Award (2007) from Soil and Water Conservation Society. Dr. Radcliffe served as a Chair of S1 Division of Soil Science Society of America (2003). His research program is funded by competitive grants from U.S. EPA, USDA–NIFA, Water Environment Foundation, Georgia Department of Natural Resources, and USDA–NRCS.

Dr. Radcliffe’s seminar will be available via live video streaming and also recorded.
